SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

Abstract

Two accelerometer systems, the Orbital Acceleration Research Experiment and the Space Acceleration

Measurement System, were used to measure and record the microgravity environment of the Orbiter

Columbia during the STS-87 mission in November-December 1997. Data from two separate Space

Acceleration Measurement System units were telemetered to the ground during the mission and data

plots were displayed for investigators of the Fourth United States Microgravity Payload experiments in

near real-time using the World Wide Web. Plots generated using Orbital Acceleration Research

Experiment data (telemetered to the ground using a tape delay) were provided to the investigators using

the World Wide Web approximately twelve hours after data recording.

Disturbances in the microgravity environment as recorded by these instruments are grouped by source

type: Orbiter systems, on-board activities, payload operations, and unknown sources. The environment

related to the Ku-band antenna dither, Orbiter structural modes, attitude deadband collapses, water dump

operations, crew sleep, and crew exercise was comparable to the effects of these sources on previous

Orbiter missions. Disturbances related to operations of the Isothermal Dendritic Growth Experiment

and Space Acceleration Measurement Systems that were not observed on previous missions are detailed.

The effects of Orbiter cabin and airlock depressurization and extravehicular activities are also reported

for the first time. A set of data plots representing the entire mission is included in the CD-ROM version

of this report.

1. Introduction

The STS-87 mission launched on the Space Shuttle Orbiter Columbia at 1997/323/19:46:00 Greenwich

Mean Time, which corresponds to Eastern Standard Time 14:46 on 19 November 1997. Wheel stop

upon landing was at 1997/339/12:21:02 Greenwich Mean Time. In addition to Greenwich Mean Time,

the timing convention typically used on Orbiter missions is Mission Elapsed Time (MET). This timing

system provides a measure of time elapsed since launch in days/hours:minutes:seconds. For STS-87,

wheel stop occurred at MET 015/16:35:02. The payloads manifested on this mission include the

microgravity experiments of the Fourth United States Microgravity Payload (USMP-4): three materials

science experiments growing semiconductor crystals in the Advanced Automated Directional

Solidification Furnace (AADSF); a fundamental physics investigation called the Confined Helium

Experiment (CHeX); a study geared towards an improved understanding of the growth of metals, the

Isothermal Dendritic Growth Experiment (IDGE); a semiconductor crystal growth experiment in the

French furnace MEPHISTO; combustion science studies of Enclosed Laminar Flames (ELF); materials

science investigations into Particle Engulfment and Pushing by a Solid/Liquid Interface (PEP) and the

Wetting Characteristics of Immiscibles (WCI); and two accelerometer systems, the Orbital Acceleration

Research Experiment (OARE) and the Space Acceleration Measurement System (SAMS).

One common characteristic of these experiments is that various effects of gravity make it difficult, if not

impossible, to achieve usable results when performing the experiments on Earth’s surface. Therefore,

the investigators have taken advantage of the microgravity environment afforded by being in low-Earth

orbit to perform their research. Interpretation of the experiment results both during the mission and

upon post-mission analyses of data and samples requires an understanding of the microgravity

environment in which the experiments were conducted.

This report provides the experiment teams with a post-mission interpretation of the accelerometer data

collected during the mission. The data files, processed into engineering units, are available on the

Internet; see Appendix A for data access instructions. It is such accelerometer data, combined with an

assessment of mission and experiment activities, that permits a characterization of the microgravity

environment that existed on Columbia during the mission. The text herein gives details about some

characteristics of the environment that were noted during the mission and during post-mission data

analysis. For example, the disturbances studied include the Ku-band antenna 17 Hz dither; the effect of

changing the Orbiter attitude deadband limits; the effects of different bicycle ergometer configurations;

the environment related to different Orbiter attitudes; and the effect of IDGE experiment fans and SAMS

computer hard drives. The enclosed CD-ROM contains the text of this report, plots of accelerometer

data collected during STS-87, and previous reports discussing the environment experienced by the

second and third USMP payloads [1,2]. The data plots give an overview of the environment during the

majority of the mission. The plots, which are included on the CD-ROM as Appendices B, C, D, E, and

supplementary spectrograms plotted out to the Nyquist frequencies for all SAMS sensor heads collecting

data during the mission, are also useful for identifying times when specific disturbances were apparent.

2. Mission Configuration

In addition to USMP-4, several other payloads were included on the STS-87 flight, see Table 1. The

Extravehicular Activity Demonstration Flight Test (EDFT) and the Spartan satellite deploy and retrieval

were of particular interest to the USMP-4 investigators because there was a possibility that these

activities would impact the timeline assigned to USMP-4, thus also impacting the microgravity

environment. The AADSF, CHeX, IDGE, MEPHISTO, and SAMS USMP-4 experiments were located

in the payload bay of Columbia on two Mission Peculiar Experiment Support Structures (MPESS). The

Spartan satellite and the equipment for the EDFT were also located in the payload bay, as were several

experiments on a Hitchhiker platform. Figure 1 is a schematic of the payload bay which gives an

indication of the approximate locations of the USMP-4 experiments. The OARE was attached to the

keel bridge of Columbia, underneath the other USMP-4 experiments, see Figure 2. Within the middeck,

the crew performed the USMP-4 investigations ELF, PEP, and WCI in the Middeck Glovebox Facility.

The plant growth investigations of the Collaborative Ukrainian Experiment were also conducted within

the middeck. The crew exercised on a bicycle ergometer located in the flight deck, attached to the floor

so that the long axis of the bicycle was aligned with the Orbiter XO-axis. The STS-87 crew members are

listed in Table 2.

Several of the payload bay USMP-4 experiments were started at the beginning of the mission. The

remaining experiments were initiated when the primary microgravity time started at approximately MET

005/12:00. During the designated microgravity period, the crew and Orbiter control teams attempted to

maintain a quiet microgravity environment. Prior to that time, the Spartan satellite deploy and retrieval

and EDFT activities occurred. The Spartan satellite was deployed using the Orbiter Remote

Manipulator System, with initial grapple of the satellite at MET 001/23:46. A deploy situation resulting

in an uncontrolled tumbling of the satellite resulted in replanning of the mission timeline. The satellite

was captured and returned to the payload bay by two crew members during an extravehicular activity

(EVA) at about MET 005/07:40. A portion of the EDFT was run following the satellite stow until about

MET 005/11. IDGE, Middeck Glovebox microgravity investigations, CUE operations, and Hitchhiker

experiments were performed throughout the mission. A redeployment of the Spartan and additional

EDFT activities occurred late in the mission. Times for several activities that were of interest to the

microgravity scientists are listed in Table 3. Appendix F, available on the report CD-ROM, is a copy of

the logbook kept by the Principal Investigator Microgravity Services (PIMS) team during the mission.

Numerous events of interest are indicated there. Figure 3 gives an overview of the timing of major

mission events.

3. Acceleration Measurement Program Support of USMP-4

The Microgravity Research Program’s Acceleration Measurement Program is based at the NASA Lewis

Research Center. This program provides microgravity investigators with accelerometer systems,

acceleration data analysis, and carrier microgravity environment characterization.

3.1 Accelerometer Systems on USMP-4

Two types of accelerometer systems were included in the USMP-4 contingent to provide the

experiments with a characterization of the microgravity environment of Columbia during the STS-87

mission. Two SAMS units were located on the MPESS. These units recorded and downlinked in

near real-time acceleration data in the 0.01 Hz to 100 Hz range in support of the AADSF,

MEPHISTO, CHeX, and IDGE experiments. This frequency range is mostly affected by vibrations
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

due to the operation of Orbiter and experiment apparatus and by crew activity. More information

about the SAMS is available in the literature [1-7] and details about the specific configuration of the

two SAMS units on STS-87 are provided in Table 4. SAMS Unit G, Triaxial Sensor Head (TSH) C

was activated during the mission, but set to a scientifically insignificant data sampling rate because

of data downlink restrictions. The SAMS data are reported here in terms of the Orbiter structural

coordinate system and the reference frame used is such that a forward thrust of the Orbiter is

recorded as a negative XO acceleration.

SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

During post-mission analyses for MEPHISTO in which long series of SAMS Unit F, TSH A data

were processed, it became evident that this TSH's acceleration data erroneously tracked the sensor

temperature data. This problem is most evident in the lowest frequency regime of the data.

Throughout the mission, the Orbiter was commanded to a number of different attitudes, which

resulted in different temperature profiles. For those with large temperature variations (over the

course of an orbit), the acceleration data manifests this problem most noticeably. For other periods

of relatively small temperature swings, the problem is less obvious. The analyses performed for this

report were done before this problem was noticed, but the analysis results were subsequently

examined to assure that this problem was properly accounted for.

The OARE measures the quasi-steady acceleration environment of the Orbiter Columbia. The

OARE was mounted to the floor of Columbia's cargo bay on a keel bridge, close to the Orbiter

center of mass in the Orbiter X O - and YO -axes. The location and orientation of the sensor with

respect to the Orbiter structural coordinate system are given in Table 5. The quasi-steady

microgravity environment is affected by aerodynamic drag on the Orbiter, gravity gradient effects,

rotational motion of the Orbiter about its center of mass, maneuvering of the Orbiter, venting of

water and air from the Orbiter, and crew activity. More information about OARE is available in

references [8-11]. On STS-87, the OARE was configured such that data were recorded on-board the

Orbiter and sent down to the ground periodically. The data are reported in terms of the Orbiter body

coordinate system with a frame of reference fixed to the Orbiter, such that a forward thrust of the

Orbiter (for example, during an Orbital Maneuvering System burn) is recorded as a negative Xb-axis

acceleration because a free particle would appear to translate in the negative Xb-axis direction

relative to the Orbiter.

The OARE was designed to measure quasi-steady accelerations from below 1x10-8 g up to

2.5x10-3 g. The OARE consists of an electrostatically suspended proof mass sensor, an in-flight

calibration subsystem, and a microprocessor which is used for in-flight experiment control,

processing, and storage of flight data. In support of USMP-4 experiments, the sensor output

acceleration signal was filtered with a Bessel filter with a cutoff frequency of 1 Hz. The output

signal was digitized at 10 samples per second and was processed and digitally filtered with an

adaptive trimmean filter prior to electronic storage.

OARE data are available from MET 00/00:11 through sensor saturation at MET 015/14:34 during

Orbiter re-entry. Appendix A describes how these data can be accessed through the Internet.

3.2 Accelerometer Data Flow During STS-87

The PIMS team is tasked to characterize the microgravity environment of spacecraft and other

carriers used by NASA Microgravity Research Program investigators. Prior to flight, PIMS talked

to USMP-4 project scientists and principal investigators in an effort to understand the nature of

acceleration data support required for real-time, near real-time, and post-mission analysis. These

inquiries resulted in identification of the accelerometer systems, the frequency characteristics of the

SAMS sensor heads, the real-time plot formats, and near real-time plot formats to be used in support

of the USMP-4 experiments. A combination of each of these items would allow the best correlation

between acceleration events and experiment science data.

Real-time support of the science teams was accomplished exclusively using SAMS data.

Throughout the mission, PIMS received real-time downlink data from both SAMS units, converted

the raw SAMS telemetry frame to engineering unit data, and generated data plots in the format

requested pre-mission by the USMP-4 principal investigators. Periodic updates to the plotted images

were made available approximately every two minutes through the PIMS USMP-4 World Wide Web

(WWW) page.

The plot types developed by PIMS for Unit G, TSH B real-time data were driven specifically by the

CHeX experiment team. Throughout the entire USMP-4 segment of the mission, the CHeX team

requested plots of real-time acceleration versus time, interval maximum absolute value acceleration

versus time, power spectral density, color spectrograms, and gRMS versus time (for three frequency

bands specified by CHeX). The plot types displayed using the Unit F, TSH A real-time data were

acceleration versus time and color spectrograms. PIMS selected these plots as a compromise among

varied plot type requests for the Unit F, TSH A data.

The unprocessed OARE data were recorded on the Orbiter payload tape recorder and telemetered to

the ground approximately 8-10 hours after the measurement. Because the OARE data on USMP-4

were not available in real-time, payload recorder dumps containing the OARE data were processed

by Marshall Space Flight Center's Data Reduction group for subsequent processing by PIMS

computers located at the NASA Lewis Research Center's Telescience Support Center. The results of

OARE data analysis were made available to the USMP-4 teams via the PIMS WWW page

approximately ten to twelve hours after the actual measurement time had transpired. The plot types

developed by PIMS using OARE data were limited to trimmean filtered acceleration versus time as

measured at the OARE location and mathematically mapped to the following locations within the

Orbiter: Orbiter center of mass, AADSF experiment location, and IDGE experiment location. See

Table 6 for the structural coordinates used for these locations.

The AADSF experiment team requested processing of an additional set of data depicting the quasisteady acceleration environment. This data set was from the Microgravity Analysis Workstation

(MAWS). The MAWS model is used to predict the quasi-steady acceleration environment at any

point in the Orbiter. The AADSF experiment team requested comparison plots of the MAWS

predictions of the quasi-steady acceleration environment at the AADSF experiment location with the

OARE data mapped to the AADSF experiment location. These comparison plots were generated in

support of the three AADSF experiment runs.

3.3 Roadmap to Accelerometer Data Plots

Several different types of data displays are provided in this report. The analysis techniques used to

create the plots and generate data values provided in several tables are discussed at length in [12,13].

Because some readers may not be familiar with some of the plot types and also because there are

some unusual features on some of the displays, we provide here some guidance for interpreting the

plots in this report.

Line plots have clearly marked axis labels, typically time or frequency on the abscissa and

acceleration levels in units of g (9.8 m/s2), μg (1x10-6 g), gRMS (root-mean-square of acceleration

level), or g2/Hz (power spectral density, PSD) on the ordinate. Spectrograms, presented in color

throughout this report and in the appendices, represent a series of PSD calculations performed on

successive sections of data and are arranged such that the PSD information is oriented vertically on

the page with time increasing from left to right and frequency increasing from bottom to top. Each

time-frequency bin is assigned a color corresponding to the base 10 logarithm of the PSD magnitude.

4. Microgravity Environment of Columbia on STS-87

In addition to the real-time accelerometer data displays that PIMS provided during the mission, the

PIMS team also provided data analysis and interpretation during the mission in an “off-line” fashion.

When experiment team members needed information about the STS-87 microgravity environment some

time after a particular occurrence, the PIMS team used archived data to fulfill the request. During the

mission, the PIMS team received close to 100 different requests. This section provides details on the

effects that specific events had on the microgravity environment of Columbia. The data analysis in

several examples (for instance Deadband Collapse and EVA Operations) was initiated by user requests

during the mission.

4.1 Orbiter Systems

4.1.1 Ku-Band Antenna

The Ku-band antenna is located on the forward starboard sill of the Orbiter’s cargo bay. On

orbit, this antenna is used primarily for communications between the Orbiter and the ground via

the Tracking and Data Relay Satellite System. In order to maintain line-of-sight, the Ku-band

antenna must slew to compensate for motion of the Orbiter with respect to these communications

satellites. The Ku-band antenna is mounted on gimbals, which allow for this tracking; however,

the antenna must be dithered at 17 Hz to prevent stiction of the gimbal mechanism. Reaction

torque forces at the base of this assembly introduce a strong 17 Hz oscillatory disturbance into

the acceleration environment of the Orbiter, along with various contributions from its 2nd through

at least its 6th harmonics. Focusing analysis on a narrow spectral region (0.2 Hz wide) centered

on the dither frequency, we can track the root-mean-square (RMS) acceleration for the frequency

band from 16.93 to 17.13 Hz. Figures 4 and 5 depict 56-hour periods for this type of analysis

performed on SAMS Unit F, TSH B data for the USMP-3 and USMP-4 payloads, respectively.

For both of these missions, SAMS Unit F, TSH B was mounted on the forward MPESS at the

Orbiter structural coordinates shown in Table 7.

The vertical dashed lines at the 47-hour mark in Figures 4 and 5 indicate the Ku-band antenna

stowage time, which brings antenna dithering to an end. More details on the stowage operation

are given later in this section. Table 8 aims to quantify the measured disparity between “dither

on” and “dither off” periods. The values given represent the average RMS acceleration values

for the times shown.

While the ambient Orbiter environment for this small frequency range was measured to be under

10 μgRMS, the antenna dithering added over 100 μgRMS for both USMP-3 and USMP-4 missions.

The Euclidean distance between the two Orbiter cargo bay positions enumerated in Table 7 is

approximately 5 feet, but transmission of the dither frequency vibrations for the different

structural paths to these locations is uncertain. Table 8 suggests a couple of possibilities: the

USMP-3 location was less responsive to the 17 Hz disturbance than the USMP-4 location, and/or

the dithering intensity was somewhat greater on the latter mission. Note that acceleration

measurements recorded in the Spacelab module during STS-65/IML-2 averaged around 100

μgRMS for this same 0.2 Hz wide frequency band. This would suggest, not surprisingly, that

transmission of the Ku-band dither excitation is damped by the structure of the Spacelab module.

Speculation that a Spacelab module structural mode exists around 17 Hz is not supported by

these observations.

While the dither intensity does typically vary with time throughout most missions, there are

certain times when the intensity decreases or the dither is turned off altogether. Expected off

times take place during gimbal flips. When the Ku-band antenna is actively tracking a satellite

and the line-of-sight causes one of its two gimbals to reach their physical limit, the system will

do what is commonly called a gimbal flip. Further details on this are given in Section 5.4 of [2].

During the gimbal flip, the antenna will quickly slew (20 degrees per second) until the dish is

again pointing in the correct direction on the other side of the physical stop. During fast slew

operations, the 17 Hz dither is disabled. Figure 6 shows a Ku-band antenna gimbal flip. This

overlay plot shows SAMS Unit F, TSH B YO-axis acceleration data (blue trace, left ordinate

scale) and Johnson Space Center Mission Evaluation Workstation System (MEWS) data for the

Ku-band antenna’s alpha gimbal angle (red trace, right ordinate scale), both as a function of time.

It is clear from this plot and Table 9, that when the antenna is slewing quickly (where the slope

of the red trace is large), the dither disturbance is non-existent. Also, note that when the alpha

gimbal angle stays relatively constant at about 0 degrees for several seconds just before the

3-minute mark in Figure 6, the dither intensity dips considerably (compare first two rows of

Table 9).

Prior to de-orbit, the Ku-band antenna must be moved into its stowed position so that the payload

bay doors can be closed for re-entry. Table 10 details timing of the events for this stow

procedure. The spectrogram of Figure 7 captures the antenna stow event for the USMP-4

mission. Note that this spectrogram is plotted out to the Nyquist frequency of the data, therefore

the spectra are attenuated above 25 Hz, the cutoff frequency for this TSH. From this figure, we

see the spectral peak at the dither frequency (the red horizontal streak at 17 Hz) cease just before

the 8-minute mark. The same goes for its 2nd and 3rd harmonics, the spectral peaks at 34 and 51

Hz, respectively. These are the horizontal streaks labeled H2 and H3 in the figure. We attribute

the other spectral components, that are labeled with an A, to aliasing. The three arrows near the

lower left portion of this figure mark one final item of interest on this spectrogram. These are

times when the antenna briefly stopped dithering for the purpose of fast slewing. This is

evidenced by the large slope of the red trace on Figure 8 at these times. This plot is similar to

Figure 6, except that the blue trace here (left ordinate scale) is acceleration magnitude, instead of

the YO-axis acceleration, for SAMS Unit F, TSH B. The crew performs a cable repositioning

procedure (gimbal flip) prior to stowing the antenna. This is seen around the 4-minute mark

[14]. The dither stop time, as seen on this plot just before the 8-minute mark, occurred at MET

014/20:17:52. Mean acceleration magnitude for dither-on times in Figure 8 was 264 μg,

compared to about 83 μg for the dither-off times. The highest acceleration magnitudes recorded

in the time frame of Figure 8 were in excess of 1 milli-g, and occurred over a span of about 8

seconds just before dithering ceased. When the crew takes the “KU ANT” switch to the

“STOW” position, the system moves to prescribed stow angles. Next, the system drives the

locking pins, and then performs a “wiggle” test to verify that the pins are seated properly and that

the antenna is in a locked position. This would account for the large accelerations observed just

before the 8-minute mark of Figure 8 [15].

4.1.2 Vehicle Structural Modes

Vehicle structural modes constitute some primary components of the Orbiter’s vibratory

environment in the oscillatory region of the acceleration spectrum. In the absence of substantial

transient acceleration events or crew exercise, these resonant frequencies dominate the spectrum

below about 10 Hz. They establish the ambient oscillatory acceleration environment in this

spectral region in that they are always present with varying degrees of intensity. Crew exercise

and Orbiter thruster firings tend to excite these resonances, causing heightened acceleration

levels which persist for a short period of time before damping down toward some baseline.

As evidenced by the red vertical streaks in the spectrograms on Appendix pages C-12 and C-13,

and as documented in the STS-87 As-Flown Attitude Timeline, Columbia’s thrusters imparted

numerous impulsive accelerations in an attempt to track the wayward Spartan satellite from

about MET 002/01:20 to about MET 002/12:00. Like sporadic pinging of a tuning fork, these

firings excited the Orbiter’s natural frequencies and provided the opportunity for examining the

heightened response of these vehicle structural modes. Toward that end, spectral averaging was

performed on Hanning-windowed PSDs calculated with the parameters shown in Table 11 for the

period from MET 002/02:30 to MET 002/07:30.

F A 50 1024 660 3.75

F B 125 4096 344 3.13

G B 250 8192 346 3.15

Note that the last column shows the aggregate span of the spectral average. This does not total 5

hours, as suggested by the MET span, because any candidate PSD period containing a substantial

impulsive transient (like would be the case for a thruster firing) was ignored. The intent here

was to examine the resonant ringing after these impulsive accelerations. Figures 9, 10, and 11

show the resultant PSDs. Once these were computed, the RMS accelerations were then derived

from them via Parseval’s relation to yield the results shown in Table 12.

The resonance at 3.5 Hz represents an Orbiter fuselage torsion mode and expectedly imparts

most energy in the YO ZO-plane. The strongest structural mode resides at about 4.7 Hz and aligns

primarily with the ZO-axis. Note that structural modes can be hard to identify on plots of short

periods of time, but are readily apparent when examining a long-duration spectrogram.

The spectrogram of Figure 12 represents an arbitrary 6-hour time frame where the structural

modes quantified in Table 12 are indicated by the long horizontal ticks shown on the frequency

axis. Of these, the mode at 3.2 Hz is the most obscure, while again we see that the 4.7 Hz mode

is the most intense. The RMS accelerations shown in Table 12 were computed from a time span

of repeated impulsive battering. In order to investigate the nominal behavior of the 4.7 Hz mode

measured over a longer time frame, the RMS acceleration contributed by this mode was

computed every 81 seconds for SAMS Unit F, TSH A data, and every 66 seconds for TSH B data

from both SAMS Units F and G. This RMS acceleration tracking was performed for the 24-hour

period starting at MET 010/00:00. The results for SAMS Unit F, TSH B are shown in Figure 13.

The salient features of this plot are as follows:

• the sample rate, fs, shown in small text in the upper left portion of the figure

represents how often the RMS acceleration value was computed (one sample

every 66 seconds at 0.02 samples per second),

• the alignment of this structural mode is reinforced by comparing the ZO-axis

data (blue trace) to those of the other two axes (red trace is XO-axis, green trace

is YO-axis); essentially, the XO-and YO-axes’ data represent ambient or

background accelerations in this spectral region,

• the transition to crew wake occurs just before the 4-hour mark as seen by

heightening of the blue trace (see also Appendix page C-44) and the transition to

crew sleep occurs just before the 22-hour mark as seen by quieting of the blue

trace (see also Appendix page C-47); as expected, crew movement tends to

excite this mode,

• crew exercise periods (at around hours 4 to 6 and again at around hour 18) result

in the highest measured RMS accelerations for this mode in this 24-hour period;

in fact, when the third harmonic of the shoulder-sway frequency approaches

4.7 Hz (as seen at about MET 010/05:20 on Appendix page C-44 and at about

MET 010/17:30 on Appendix page C-46), the resonant RMS acceleration level

contributed by this mode alone approaches that of Vernier Reaction Control

System (VCRS) thruster firings.

TSH B mimic those gleaned from Figure 13. Table 13 summarizes the results for all three plots.

Comparing the shaded cells in Tables 12 and 13, note that the 4.7 Hz mode was somewhat higher

in amplitude in the aftermath of the repeated thruster firings required for satellite-tracking

maneuvers. In contrast to the steady, albeit nebulous, mode at 4.7 Hz, the apparent structural

mode at about 3.2 Hz has been observed to shift in frequency. Most notable are the spectral

shifts seen on the spectrogram of Appendix page B-50 at about MET 011/12:35, 011/13:53,

011/14:39, and 011/16:43. The cause of these frequency shifts is unknown at this time.

4.1.3 Deadband Collapse

The Orbiter's attitude with respect to its orbital path plays an important role in a number of

operational concerns. Maintaining suitable orientation for links with communications satellites,

minimizing damage by space debris, and keeping proper alignment to account for the orbital

mechanics that dictate quasi-steady acceleration levels are three motivating factors for defining

an attitude. Deadband is a term used to specify the allowable deviations (number of degrees and

rotational rate of the Orbiter) from a desired attitude. The Orbiter’s Reaction Control System is

used to maintain a desired attitude, ensuring that the chosen deadband criteria are met. The

Reaction Control System consists of the Primary Reaction Control System (PRCS) and the

VRCS. The PRCS is typically used on orbit for pitch, roll, and yaw maneuvers, while the VRCS

is used for fine adjustments of vehicle attitude. The Digital Auto Pilot (DAP) constantly

monitors the Orbiter’s orientation and governs the VRCS (or PRCS), commanding the proper

sequence and direction of thruster firings required to return to attitude when a specified deadband

limit is exceeded.

On occasion, the deadband is changed as more (or less) stringent pointing needs arise or as

vehicle health issues evolve. When the deadband is changed from a higher value to a lower one,

the allowable deviation from the nominal attitude decreases. This is referred to as a deadband

collapse. There were numerous deadband collapses during the STS-87 mission, many of them

imposed for jet temperature maintenance [16]. Table 14 is a partial list of deadband collapse

times from this mission as recorded in the PIMS logbook or as indicated by examination of the

acceleration data. For these times, the DAP was changing between the A3 (0.07° deadband) and

the A12 (1.0° deadband) settings. Note, as indicated in the center column of this table, that most

of these collapsed deadbands lasted for just a few minutes. However, there were some that lasted

for nearly 10 minutes.

Table 15 gives a rudimentary accounting of VRCS thruster firing activity during time frames

before and during two of the longer deadband collapses. The values shown in the "Number of

VRCS Firings" column were retrieved from the operational downlink database maintained as

part of MEWS. The values shown in this column were tallied such that simultaneous firings

were counted as a single firing and, because the database is incomplete, these numbers represent

a minimum value. For example, during the period MET 008/07:00:00-008/07:29:00, there were

no fewer than 22 VRCS thruster firings.

Note from the shaded rows in Table 15 that, during the two periods of deadband collapse, the

VRCS firing rate was a couple of orders of magnitude greater than during nominal periods.

Qualitative examination of the spectrogram pages from Appendix D referenced in Table 14

reveals that the increased firing frequency of the VRCS during deadband collapse tends to have

broadband spectral effects. Most noticeably, it excites the vehicle structural modes below about

10 Hz, and somewhat heightens the spectrum around the Ku-band antenna dither frequency (17

Hz) and its harmonics. Figure 14 provides a quantitative measure of the effects of the deadband

collapse that started at about MET 008/07:29:48. The data for each of the four subplots in this

figure start at MET 008/07:00. The upper-left plot is SAMS Unit F, TSH A (10 Hz) data, the

upper-right plot is SAMS Unit F, TSH B (25 Hz) data, the lower-left plot is SAMS Unit G,

TSH A (5 Hz) data, and the lower-right plot is SAMS Unit G, TSH B (100 Hz) data. Note that

the ordinate scales for the four plots shown in this figure are different. Table 16 summarizes the

acceleration magnitude disparity between a portion of the deadband collapse period (MET

008/07:31 to 008/07:37) and a period preceding this (MET 008/07:00 to 008/07:29).

The values of acceleration magnitude shown in the rightmost column of Table 16 represent the

average for the time frame indicated. As expected, for each sensor the acceleration magnitude

was greater during the deadband collapse period. The difference was more extreme for the lower

frequency sensors (TSH A for both SAMS Units F and G). This is because below 10 Hz the

acceleration spectrum of the Orbiter is dominated by vehicle structural modes, which are highly

excitable by impulsive events such as thruster firings. While this is still a factor for the higher

frequency sensors, the effect of the firings is overshadowed by vehicle subsystems and

experimental equipment vibrations above 10 Hz. For these sensors, the measured acceleration

magnitude difference mentioned above is smaller because vibrations caused by experimental

equipment and vehicle subsystems (except for RCS) are not driven by these firings.

4.1.4 Water Dump Operations

The Orbiter Food, Water, and Waste Management Subsystem provides storage and dumping

capabilities for potable and waste water [17]. Supply and waste water dumps are performed

using nozzles on the port side of the Orbiter. Water dumps from these nozzles are expected to

cause a steady acceleration of about 5.0x10-7 g in the Yb-axis [18]. Figures 15 and 16 show the

effect of a simultaneous supply water and waste water dump and of a supply water dump on the

quasi-steady acceleration environment, as represented by OARE data. These water dump plots

show contributions to the Yb-axis and to the Zb-axis. While the anticipated effects on the

acceleration environment from water dumps is exclusively in the Yb-axis, effects have been

routinely observed in the Zb-axis since STS-73/USML-2.

4.1.5 Orbiter Attitudes

A summary plot of the OARE data for the entire STS-87 mission is provided in acceleration

versus time format, Figure 17, and in Quasi-Steady Three-Dimensional Histogram (QTH)

format, Figure 18 [12]. Each plot format illustrates some unique aspects of the USMP-4 mission.

Figure 17 clearly illustrates the sleep cycles of the crew through the periodic quieting of the data

on all three axes. Peak-to-peak variations are on the order of 1x10-6 g for crew active periods and

0.2x10-6 g for crew sleep periods. Figure 18 illustrates that multiple attitudes were flown in

support of separate USMP-4 payloads and the non-microgravity payloads, including Spartan.

As a result of the multiple attitudes flown to support the STS-87 mission, many of the attitudes

are not as clearly observed by examining a QTH plot of the entire mission. This is because the

QTH plot displays data related to an Orbiter attitude as a “percentage of time spent” relative to

the total amount of OARE data under examination. For the QTH plot for the entire mission, this

can result in an attitude’s contribution being somewhat “washed out,” if the time spent at that

attitude was relatively short when compared to the entire length of the mission. The various

attitudes of the STS-87 mission are more clearly observed by separating Figure 18 into two QTH

images, one for non-microgravity periods (Figure 19) and one for microgravity periods (Figure

20). Figure 19 examines the first 96 hours of the STS-87 mission while Figure 20 examines the

remaining 280 hours of OARE data. The additional attitudes observed in these two plots are

annotated in the plots themselves. Note the variable trace in Figure 20 introduced by the solar

inertial attitude in days 14/15. The respective quasi-steady acceleration magnitudes for each of

these attitudes can be extracted from the plots.

4.1.6 Radiator Deployment

Radiator panels attached to the forward payload doors are part of the Active Thermal Control

System which provides Orbiter heat rejection during a mission. The port and starboard side

radiators can be deployed independently to accommodate the heat rejection requirements for a

particular Orbiter attitude or mission. An electromechanical actuation system on the door

unlatches and deploys the radiators when open and latches and stows the radiators when closed

[19]. In deploying each radiator, six motor driven latches are unlocked and the deploy motor
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

18

moves the radiator to the desired position.

The deployment or stowage of either the port or starboard side radiators results in a general

excitation of the Orbiter structural modes. In particular, the 6.3 Hz structural mode and its 2nd

and 3rd harmonics are excited. Figure 21 combines PSDs for periods just prior to (red), during

(blue), and just after (green) deployment of the port side radiator. The excitation of the 6.3 Hz

structural mode and its harmonics is readily apparent, as is a spectral component around 9.5 Hz.

Figure 22 is an acceleration vector magnitude versus time plot during deployment of the port

side radiator. The increased magnitude around the 150-second mark of this plot illustrates the

impact of the radiator deployment on the environment.

4.2 On-board Activities

Numerous objectives slated for this mission kept the Orbiter crew busy for the duration of their work

periods. Vehicle maintenance, Spartan satellite deployment/retrieval, spacewalks, and microgravity

science were some of the key responsibilities that consumed crew time. Crew movement on-board

and in the payload bay translates to vibrational disturbances being introduced to the Orbiter’s

microgravity environment. The extent and character of the disturbances attributable to crew activity

can best be examined in differential fashion. That is, comparison of the acceleration environment

during times when the crew is active versus times when they are not active is desired. Generally,

single shift crew sleep and Public Affairs Office (PAO) events offer extended periods of crew

inactivity. For this mission, both of these scenarios took place and serve as contrast to the impact of

nominal crew activity. On the other extreme, crew exercise can have a severe impact on the

microgravity environment. On STS-87, an exercise vibration isolation device was used to minimize

the effects on the sensitive USMP-4 experiments.

4.2.1 Crew Sleep Cycle

Table 17 shows the MET start and stop times of crew sleep taken from the mission replanned

timeline. This table shows that the nominal scheduled sleep duration was eight hours, and sleep

start times shifted forward in time as the mission progressed as dictated by landing and Spartan

deployment constraints. As human nature has it, the start time for sleep can be planned, but the

transition is certainly not instantaneous. On the other hand, the sleep stop time can be enforced

with an alarm, which in this case was a daily wake-up song that was broadcast up to the crew.

These facts are evidenced by examining the sleep start/stop times in the Appendix plot pages

referenced in Table 17. For example, compare the transition of spectral levels (most evident

below about 13 Hz) that occurs around MET 003/14:40 on page B-18 to the transition that occurs

at around MET 003/22:00 on page B-19. These typify the effects seen when the crew transitions

to sleep and to wake, respectively.

The spectrograms cited in Table 17 show an obvious quieting below about 13 Hz when the crew

transitions from wake to sleep, however, they do not indicate with much precision how much

quieter the acceleration environment becomes. In order to obtain an accounting of this detail, the

RMS acceleration level contributed by the spectrum below 13 Hz was calculated approximately
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

19

every 66 seconds for a 96-hour span (MET 009/12:00 to 013/12:00) for SAMS TSH B on both

Units F and G. Figure 23 shows the results of these calculations for Unit F. The four pairs of

consecutive dashed/solid red lines indicate scheduled crew sleep start/stop times, respectively,

for this 4-day time frame. Note again that actual reduction in acceleration levels typically lags

scheduled sleep start times by at least several minutes, while increased excitation of the

environment is coincident with the scheduled wake times owing to the daily wake-up song. For

the plot shown in Figure 23, the mean RMS acceleration during the non-sleep times was 62

μgRMS, while the mean RMS acceleration during the four sleep periods was 23 μgRMS.

Calculations for Unit G yield a mean RMS acceleration during non-sleep times of 55 μgRMS, and

a mean RMS acceleration during sleep periods of 29 μgRMS.

014/22:00 B-63 015/07:00 B-65

As might be expected, the crew may have to wake during a sleep period for one reason or

another. It is quite possible that this is what happened at around MET 003/17:20, see

spectrogram on Appendix page D-18. Note in this plot that there are 5 to 10 minutes of

heightened spectral response, particularly below 10 Hz, starting just before MET 003/17:20.

This period coincides with an entry in the PIMS mission logbook, which notes that the IDGE

science team observed “their crystal rotate and move” at that time. The correlation implied here

is not a definitive cause-and-effect identification, it is merely conjecture. The IDGE team's
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

20

concern about their crystal motion prompted an unsuccessful search (by Marshall Space Flight

Center and Johnson Space Center controllers) for specific disturbance sources.

While the whole mission OARE acceleration versus time plot shown in Figure 17 clearly

demonstrates the sleep cycles of the crew, QTH plots can be employed to examine the relative

excursions in the OARE data during crew sleep versus crew active periods. Figure 24 is a QTH

plot created using a concatenation of OARE data from all the USMP-4 crew sleep periods from

MET 004/00:00:00 to the end of the mission. Similarly, Figure 25 is a QTH plot created using a

concatenation of OARE data from all the crew active periods for the same period of time. A

comparison of the figures clearly shows the effect of crew activity on the OARE data. Figure 24

indicates a tight clustering of the recorded OARE data during crew sleep, which permits a more

straightforward extraction of the quasi-steady acceleration vector from the OARE data. The

increased scatter observable in the data of Figure 25 demonstrates the impact of the crew and

equipment on the quasi-steady acceleration environment. Note, the circular/oval shaped

signature in Figure 24 is the result of the Orbiter being in a solar inertial attitude during one of

the crew sleep periods.

4.2.2 PAO Events

While crew sleep clearly provides a certain measure of quieting as detailed earlier, there are other

non-sleep times during a mission that afford similar effects on the acceleration environment.

Most notably, PAO events offer at least a brief respite for the crew. During a typical PAO event,

the crew is relatively motionless and gathered in front of a camera for audio and video

communications with interested parties on the ground. This period of minimal movement

mimics that of sleep from an acceleration disturbance perspective, albeit for a much shorter time

span. PAO events normally last around 15 to 20 minutes, compared to the 8-hour sleep periods.

For this mission, the crew participated in more than a half dozen PAO events; Table 18 lists six

of these that show up prominently on the spectrograms on the Appendix plot pages listed in the

table.

21

The longer-than-normal PAO event that takes place starting at about MET 012/14:49 (see

Appendix page B-54) exemplifies the quietude, especially below about 13 Hz or so, which can

be achieved by minimizing crew movement. For person-intensive tasks, this restriction might be

impractical or unfeasible, but situational awareness and planning may facilitate maximum usage

of desirable acceleration environmental conditions at some time in the future of microgravity

research.

The quasi-steady environment measured by OARE also exhibits a noticeable quieting during

PAO events. Figure 26 shows the effect of the fifth PAO event listed in Table 18 on the quasisteady acceleration environment. With the reduced crew activity, the quasi-steady acceleration

environment variations are more pronounced, much like the effects observed for crew sleep

periods. The variations in the OARE data during PAO events is typically 0.2x10-6 g peak-topeak. Non-PAO time intervals demonstrate a peak-to-peak variation of 1x10-6 g.

4.2.3 Bicycle Ergometer Isolation

While crew sleep periods and PAO events provide quiet microgravity conditions, other crew

activity is routinely observed to have a negative effect on the microgravity environment. Crew

members are expected to exercise to maintain physical conditioning. On STS-87, aerobic

exercise was achieved using a bicycle ergometer. During the first few days of the mission, the

ergometer was mounted to the Orbiter with each of three configurations of an ergometer

vibration isolation system called the Passive Cycle Isolation System (PCIS). During mission

planning, the mission management team requested that the PIMS team provide analysis of the

SAMS Unit F, TSH A data collected during these initial days of crew exercise to assist them in

assessing the vibration isolation performance of the PCIS. Two types of analysis were employed

to quantify the differences measured by the SAMS among the three PCIS configurations and a

hardmount configuration: (1) ∆gRMS derived from interval RMS acceleration versus time, and (2)

cumulative RMS acceleration versus frequency.

The ∆gRMS derived from interval RMS acceleration versus time analysis was aimed at quantifying

the change in the RMS acceleration level for two distinct periods: a non-exercise baseline period

and the exercise period of interest. Care was taken to ensure that no strong, non-exercise related

disturbances below 10 Hz were present for one period and not for the other. A spectrogram plot

spanning both the baseline and the exercise periods served as the basis for this check. From this

spectrogram, periods were identified as baseline and as exercise. Once these periods were

selected, a 0.5-second interval RMS acceleration versus time curve was plotted for the same time

span covered by the spectrogram. Based on this plot, the difference in the median of the RMS

acceleration values between the baseline and exercise periods was calculated. This was done for

the three (XYZ) orthogonal Orbiter structural axes and for the overall RMS acceleration

calculated from the root-sum-of-squares (RSS) of the XYZ RMS acceleration values. The

results were compiled in near real-time in tabular form on a PIMS WWW page.
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

22

After the ∆gRMS values were calculated, the cumulative RMS acceleration versus frequency

curves for both the baseline and exercise periods were plotted. These served to quantify the

contributions of spectral components at and below a given frequency to the overall RMS

acceleration level for the periods of interest.

Commander Kevin Kregel was the only crew member to exercise in all of the ergometer

configurations. Configuration #1 used stiff PCIS mounts on the front of the ergometer and stiff

mounts at the seat connection; #2 used soft front and stiff seat connections; and #3 used stiff

front and soft seat mounts. Based on analyses of Kregel's early exercise (see Table 19 below),

several observations were made. Overall, the PCIS configuration #3 was better than either of the

first two configurations. For the XO-axis only, the PCIS configuration #2 was the best. For the

YO-axis only, the PCIS configuration #1 was the best. For the ZO -axis, the hardmount was the

best. The differences among the three PCIS configurations were marginal in all cases.

RECOMMENDED PCIS CONFIGURATION: It appears that the differences

among the three configurations are marginal. However, after analyzing the

∆gRMS (gRMS exercise - gRMS background) values for the three configurations,

the final configuration was found to have the overall lowest value. Therefore,

the Mission Scientist recommends the final configuration #3 as the optimum

PCIS configuration for [Flight Days] 5-14.

The real-time PCIS data analysis relied exclusively on the SAMS Unit F, TSH A data which had

the temperature/acceleration data problem mentioned earlier. This analysis, however, was done

in a differential fashion, whereby the ∆gRMS between baseline and exercise periods was the

decisive quantity. Assuming that the anomalous low-frequency component varied only slightly

over the span of the baseline and exercise periods, then this analysis should not have been

significantly affected.

4.3 Payload Operations

4.3.1 IDGE-Related Disturbances

Early in the mission, following activation of the USMP-4 experiments, a set of acceleration

disturbances clustered around 56 Hz was noticed in the real-time spectrogram displays of SAMS

Unit G, TSH B. See, for example, the pronounced red horizontal streaks at this frequency in the

spectrograms of Appendix D. The CHeX team expressed concern about these disturbances

because of their experiment susceptibility to vibrations around 55 Hz. During the first few days

of the mission, an investigation was conducted by consulting with the various experiment teams,

Spacelab-MPESS support staff, and Orbiter subsystem personnel to ascertain the source of these

disturbances. In discussions with IDGE personnel, it was discovered that there were seven

cooling fans within the IDGE apparatus. One of the fans had its speed controlled according to a

measured internal IDGE temperature.

The spectrogram on Appendix page D-65 shows the SAMS Unit G, TSH B data during the IDGE

experiment deactivation time on MET day 015. In addition to the 56 Hz traces, the variable trace

between 35 and 40 Hz and a 74 Hz disturbance cease at the time of the IDGE power-off at about

MET 015/09:45. When the IDGE and SAMS units were returned to NASA Lewis Research

Center after de-integration from the Orbiter, a vibration assessment was performed with the

IDGE flight apparatus and SAMS Unit G, TSH B. The data acquired by SAMS for this test are

shown in Figure 27. This test confirmed that the variable 35 to 40 Hz trace, the traces around 56

Hz, and the 74 Hz disturbance were all related to IDGE fans.

During the ground testing of the IDGE hardware, another as-yet-unidentified disturbance evident

in the SAMS data was potentially assigned to IDGE. This disturbance was manifested as a

persistent spectral peak at 21 Hz (1260 rpm if a rotational source) and can be seen to start and

stop in the bench test SAMS data shown in Figure 27. A similar disturbance was seen in the

mission data. It was tightly controlled in frequency and spanned the time frame from

approximately MET 000/20:39 (see Appendix page B-7) to MET 014/15:30 (see Appendix page
SUMMARY REPORT OF MISSION ACCELERATION MEASUREMENTS FOR STS-87

24

B-62) with only two brief pauses. The first intermission started at about MET 001/05:19 and

lasted just under 7 minutes (see Appendix page B-8). The second started at about MET

013/09:58 and lasted just over 15 minutes (see Appendix page B-57). To quantify this

disturbance, its RMS acceleration was computed every 33 seconds for the 24-hour period starting

at MET 004/00:00 for TSH B on both SAMS Units F and G. The physical separation of these

two heads and their cutoff frequencies enabled a comparison of the measured impact of this

disturbance at two different locations in the Orbiter’s payload bay. Figure 28 shows the RMS

acceleration versus time for the frequency range from 20.8 to 21.1 Hz for SAMS Unit F, TSH B

measurements. As seen, the intensity of this disturbance is somewhat variable; similar analyses

of SAMS Unit G, TSH B data lead to the results summarized in Table 20. The RMS values

indicate that this disturbance is relatively close in intensity at the two different sensor locations.

plots display data up to the filter cutoff frequency for the SAMS data. When characterizing the

microgravity environment of the Orbiter, it is useful to also examine spectrograms that show data

out to the Nyquist frequency, even though the acceleration energy represented by the plot

between the cutoff and Nyquist frequencies is suppressed by filtering [12]. Such spectrograms

are included on the report CD-ROM. While studying the SAMS Unit G, TSH B Nyquist

frequency spectrograms, a strong, persistent 120 Hz disturbance was noticed. Subsequent

discussions with the SAMS engineering team and evaluation of groundtest data led to the

determination that the 120 Hz disturbance was caused by the 7200 rpm rotation of the SAMS

computer hard disk drives used to record data on orbit.

4.3.3 Orbiter Cabin and Airlock Depressurization

In preparation for the two EVAs conducted during the STS-87 mission, the crew cabin and the

airlock had to be depressurized to various degrees. In preparation for both EVAs, the cabin was

depressurized from a nominal 14.7 psi to 10.2 psi. Prior to egress, the airlock was depressurized

from 10.2 psi to the vacuum of space. This airlock depressurization was performed in two steps,

from 10.2 psi to 5.5 psi and from 5.5 psi to vacuum. The air removed from the Orbiter during

depressurization was vented through a relief valve located on the port side of the Orbiter. This

relief valve is located very near the valves used for conducting supply water and waste water

dumps. This was the first mission where the effects of cabin depressurization and airlock

depressurization on the microgravity acceleration environment were measured and recorded.

The effects of cabin depressurization and airlock depressurization are most evident in the quasisteady acceleration environment. The OARE Yb-axis and the OARE Zb-axis data shown in

Figures 29 and 30 indicate that the magnitude of the cabin depressurization can be as large as

10 μg. The OARE Yb-axis and the OARE Zb-axis data shown in Figures 31 and 32 indicate the

magnitude of the airlock depressurization can be as large as 5 μg.

Figure 33 illustrates the two step process involved in performing the airlock depressurization.

The red trace in Figure 33 is the differential pressure between the airlock and the payload bay as

indicated by data retrieved from the MEWS system. The change in the differential pressure

approximately 23 minutes into the plot causes a corresponding change in the quasi-steady

acceleration environment of about 5 μg. When 5.5 psi is reached, the venting is stopped for

about 5 minutes. The next change in pressure results in further venting that also affects the

quasi-steady acceleration environment.

4.3.4 EVA Operations

As NASA prepares to build the International Space Station in collaboration with its international

partners, successful completion of EVA missions becomes critical. Designers and mission

planners are developing the equipment and procedures for constructing the space station and,

while a good deal of testing can be done on the ground, certain tests must be performed on orbit.

Lessons learned from a series of EVA tests will serve to increase the experience base of hardware

developers, flight controllers, and the astronauts doing the spacewalks [20]. During the STS-87

mission, astronauts Winston Scott and Takao Doi performed two EVAs. Grappling and berthing

of the wayward Spartan satellite consumed much of the time on the first of these. The second

was focused on evaluation of equipment and procedures that will be used during construction

and maintenance of the International Space Station. This spacewalk was intended to accomplish

all of the primary objectives originally planned as part of the STS-80 mission in November 1996

that were not achieved due to a stuck airlock hatch [21].

For convenience, the first EVA, which took place from about MET 005/04:30 to 005/11:50 will

be referred to as EVA #1, and the one that took place from about MET 013/13:20 to 013/18:15

will be referred to as EVA #2 in the remainder of this report. A cursory examination of the

SAMS data collected during these times shows that these EVAs tended to excite the acceleration

spectrum below about 50 Hz. This increased excitation can be seen in a relative manner by

comparing Appendix D Figures 22 (during EVA #1) to 23 (after EVA #1) for SAMS Unit G,

TSH B on pages D-25 and D-26. In order to quantify this comparison and to gain a better

understanding of the effects that an EVA activity has on the Orbiter’s acceleration environment,

the RMS accelerations for a number of frequency bands were calculated as a function of time.

The RMS acceleration for each of the frequency bands shown in Table 21 was computed every

32.768 seconds from the SAMS Unit G, TSH B data for the period MET 005/06:30 to 005/15:30,

which spans most of EVA #1 and a few hours thereafter; and for the period MET 013/13:00 to

013/22:00, which spans most of EVA #2 and a few hours following. The RMS levels shown in

the “During EVA” columns represent the median values during part of the EVA (MET 005/07:30

to 005/10:30 for EVA #1, and MET 013/13:20 to 013/16:20 for EVA #2), while the “After EVA”

columns show the median values after the EVA (MET 005/12:30 to 005/15:30 for EVA #1, and

MET 013/19:00 to 013/22:00 for EVA #2). Note that for each band the levels during the EVAs

were higher, although only marginally so above about 50 Hz. The RMS acceleration levels for

the 0-10, 10-20, and 30-40 Hz bands for this sensor are appreciably lower after the EVAs. For

example, a plot of the RMS acceleration versus time for the first band (0 to 10 Hz) is shown in

Figure 34. The red segment of the trace indicates the “During EVA #1” time frame considered

for Table 21, while the blue segment indicates the “After EVA #1” span. Note from the figure

the obvious disparity in RMS levels for this frequency band.

SAMS Unit F, TSH A and B data were analyzed as described above, with the exception that the

analysis was limited by the lowpass filter cutoff frequencies of these heads (10 Hz for TSH A,

and 25 Hz for TSH B). The results shown in Tables 22 and 23 for Unit F are similar to those

obtained for Unit G.

To further investigate the sources of disturbance that may have contributed to the measured

accelerations during the two EVAs, Orbiter thruster firing activity was analyzed. The MEWS

software enabled access to a record, albeit incomplete, of Columbia’s Reaction Control System

thruster firing times. The firing count shown in the right-hand column of Table 24 gives the

minimum number of times that the VRCS jets were fired. Simultaneous firings were counted as

one. The PRCS thrusters were not fired during either EVA according to the MEWS data.

Table 24. Orbiter VRCS Thruster Firing Activity During EVAs

MET VRCS Thruster Firing Count

005/08:00 - 005/11:00 (during EVA #1) 154

005/12:00 - 005/15:00 (after EVA #1) 640

013/13:40 - 013/16:40 (during EVA #2) 414

013/19:00 - 013/22:00 (after EVA #2) 66

For EVA #1, these data indicate that the increased excitation observed during the spacewalk is

not attributable to thruster firings. The same implication cannot be gleaned from the firing count

numbers for EVA #2 taken alone, however, when considered in conjunction with those of EVA

#1, we infer that the thruster firings did not play a defining role in heightening the acceleration

spectra in some preferential manner during the EVAs. The nature of the work being done during

these spacewalks may help to explain the increased acceleration levels. It stands to reason that

cumbersome space suits and “construction” work requires greater forces be exerted by the

astronauts than nominal crew compartment activities. Also, during the EVAs the astronauts were

closer to the SAMS sensors; spacewalk disturbances originated in the Orbiter’s cargo bay, where

the SAMS heads were mounted, instead of the middeck or flight deck, where the crew was the

remainder of the mission.

4.4 Unknown Disturbance Sources

4.4.1 Twin Disturbances at 12 to 15 Hz

An unidentified pair of disturbances shows up as two closely spaced spectral peaks, most clearly

seen in the spectrograms of Appendix B. These twin disturbances tend to track each other in the

frequency domain, and gradually increase in frequency from around 12 Hz early in the mission

to over 15 Hz on MET day 11. They exhibit sharp spectral transitions on occasion. For

example, see Appendix pages B-31 and B-32 until about MET 007/01:30, Appendix pages B-35

and B-36 until about MET 008/01:40, and Appendix page B-47 at about MET 010/22:50. These

disturbances are hard to discern from about MET 008/06:30 (Appendix page B-37) to about

MET 008/18:00 (Appendix page B-38), and apparently cease sometime around MET 011/04:30

(Appendix page B-48).

4.4.2 Unknown 11.35 Hz Disturbance

An unidentified disturbance at 11.35 Hz, along with its 2nd harmonic at 22.70 Hz, is visible

occasionally in the Appendix B spectrograms. The first occurrence of this disturbance was at

approximately MET 009/14:30:00 and the last occurrence was at approximately MET

010/09:00:00. There exist eleven occurrences of this disturbance, the maximum duration being

about 15 minutes. Typical durations seem to be approximately 5 minutes in length.

Figure 35 is a plot of RMS acceleration versus time for the narrow frequency band 11.25 Hz to

11.45 Hz. The intent of this analysis was to compare the signal in this frequency band when the

11.35 Hz signal was active versus when it was inactive. The elevated levels from the 0 to 10

minute mark and from the 90 to 100 minute mark represent intervals when the 11.35 Hz signal

was present and clearly illustrate the change in signal. Appendix page B-43 shows the

spectrogram representation of this condition from MET 009/22:00 to 010/00:00.

5. Summary

The OARE and two SAMS units were used to measure and record the microgravity environment of the

Orbiter Columbia during the STS-87 mission in November-December 1997. Data from the two SAMS

units were telemetered to the ground during the mission and data plots were displayed for USMP-4

investigators in near real-time using the World Wide Web. During SAMS data processing after the

mission, it was determined that there was a problem with temperature / acceleration signals on SAMS

Unit F, TSH A. The effects of this problem can be removed from the data in some types of analyses.

Plots generated using OARE data telemetered to the ground were provided to the investigators

approximately twelve hours after data recording using the World Wide Web.

Disturbances in the microgravity environment as recorded by these instruments are grouped by source

type in this report: Orbiter systems, on-board activities, payload operations, and unknown sources. The

environment related to the Ku-band antenna dither, Orbiter structural modes, attitude deadband

collapses, water dump operations, crew sleep, and crew exercise was comparable to the effects of these

sources on previous Orbiter missions. RMS acceleration levels for the Ku-band dither disturbance

(16.93 to 17.13 Hz) were about 1.9x10-4 gRMS during USMP-4. Average RMS acceleration levels for the

4.7 Hz Orbiter structural mode ranged from 2x10-6 gRMS for the least affected XO-axis to 3x10-5 gRMS for

the most affected ZO-axis. Attitude deadband collapses necessitated by VRCS jet conditions tended to

increase the VRCS jet firing rate from approximately one firing per minute for the standard deadband

(1.0°) to greater than 100 firings per minute for the collapsed deadband (0.07°). Disturbances related to

operations of the IDGE fans and SAMS hard drives that were not observed on previous missions are

detailed in the text.

The effects of EVAs and related Orbiter cabin depressurization on the microgravity environment are

reported. The exact cause of heightened SAMS-recorded acceleration spectral levels during EVAs is not

known, although the nature and location of the work being done during the STS-87 spacewalks may

help to explain the increased levels. The effects of the cabin depressurizations performed to prepare the

spacewalking astronauts for their EVAs were best seen in the OARE data as excursions from the

background acceleration levels of as much as 1x10-5 g.

The attached CD-ROM version of this report contains the text and figures of this hard-copy along with

Appendix plots and supplementary plots representing the entire mission. These spectrograms are for

each of the four SAMS sensor heads that recorded data during the mission. The plots are useful in

identifying relative acceleration levels and the approximate start and stop times of disturbances.

Appendix A: Accessing Acceleration Data Via the Internet

SAMS and OARE data are available over the Internet from the NASA Lewis Research Center file server

“beech.lerc.nasa.gov”. Acceleration data files are arranged in a tree-like structure. Data are first

separated based upon accelerometer and then by mission. For SAMS data files, the data are further

subdivided based upon some portion of the mission, sensor head, year (for Mir data), day, and finally

type of data file (acceleration, temperature, or gain). The following figure illustrates this structure.

The SAMS data files (located at the bottom of the tree structure) are named based upon the contents of

the file. For example, a file named “axm00102.15r” would contain TSH A data for the X-axis for day

001, hour 02, file 1 of 5. The readme.doc file gives a complete explanation of the file naming

convention.

OARE data files also follow a tree-like structure, but with different branches. The data are first divided

based upon mission, and then are divided by type of data. The OARE tree structure looks like this:

Files under the canopus directory are trimmean filter data, computed by Canopus Systems, Inc. Files

under the msfc-raw directory contain the telemetry data files provided to PIMS by the Marshall Space

Flight Center Payload Operations Control Center data reduction group. Files under the msfc-processed

directory are raw files containing binary floating point values, listing the MET (in hours), and the x, y,

and z axis acceleration in micro-g’s. See the readme files under the canopus directory for complete data

descriptions.

Data access tools for different computer platforms (MS-DOS, Macintosh, SunOS, and MS-Windows)

are available in the /pub/UTILS directory.

The beech file server can be accessed via anonymous File Transfer Protocol (ftp), as follows:

 1) Open a connection to “beech.lerc.nasa.gov”

 2) Login as userid “anonymous”

 3) Enter your e-mail address as the password

 4) Change directory to pub

 5) List the files and directories in the /pub directory

 6) Change directory to the accelerometer of interest

 7) Change directory to the mission of interest

 8) Use the data file structures (described above) to locate the desired files

 9) Enable binary file transfers

10) Transfer the desired files

If you encounter difficulty in accessing the data using the file server, send an electronic mail message to

“pims@lerc.nasa.gov”. Please describe the nature of the difficulty and also give a description of the

hardware and software you are using to access the file server.

Appendix B: SAMS Color Spectrograms for Unit F, TSH B

The PIMS group has processed SAMS data from STS-87, Unit F, TSH B to produce the plots shown

here. These data were collected at 125 samples per second, and a 25 Hz low pass filter was applied to

the data by the SAMS unit prior to digitization. Prior to plot production, the raw SAMS data were

compensated for gain changes, and then demeaned. Demeaning was accomplished by analyzing

individual sections with a nominal length of 30 minutes. Users who are interested in further details for

either of these operations are encouraged to contact the PIMS group.

Color spectrograms are used to show how the microgravity environment varies in intensity with respect

to both the time and frequency domains. These spectrograms are provided as an overview of the

frequency characteristics of the SAMS data during the mission. Each spectrogram is a composite of six

hour’s worth of data. The time resolution used to compute the spectrograms seen here is 16.4 seconds.

This corresponds to a frequency resolution of 0.06 Hz.

In order to produce the spectrogram image, PSDs were computed for successive time intervals (the

length of the interval is equal to the time resolution). For the PSD computation, a Hanning window was

applied. In order to combine all three axes into a single plot to show an overall level, a vector

magnitude (VM) operation was performed. Stated mathematically:

VM PSD PSD PSD k xyz kkk = ++ 222 .

By imaging the base 10 logarithm (log10 ) magnitude as a color and stacking successive PSDs from left

to right, variations of PSD magnitude and frequency are shown as a function of time. Colors are

assigned to discrete magnitude ranges, so that there are 207 colors assigned to the entire range of

magnitudes shown.

The colorbar limits are chosen in order to minimize saturation in a given set of spectrogram plots. Data

which fall outside of these limits will be imaged as either the highest or lowest magnitude, depending on

which side they have saturated. If an area of interest seems to be saturated, care should be taken because

the actual values may lie above or below the color mapping shown on the plot.

Due to the nature of spectrograms, care should be taken to not merely read a color’s numeric value as

being the “amount” of acceleration that is present at a given frequency. In order to get this type of

information, the PSDs must be integrated between two frequencies. These frequencies (lower and

upper) form the band of interest. The result of this integration is the gRMS acceleration level in the

f f lower upper [ ] , band. The PIMS group is able to provide this type of analysis on a per-request basis.

Plot gaps (if any exist) are shown by either white or dark blue areas on the page. If a plot gap exists for

an entire plot (or series of successive plots), a comment is placed on the page to let the user know there

is a gap in the data. These “no data available” comments will not show exact times for which the data

are not available, but will only indicate missing plots.

Appendix C: SAMS Color Spectrograms for Unit F, TSH A

The PIMS group has processed SAMS data from STS-87, Unit F, TSH A to produce the plots shown

here. These data were collected at 50 samples per second, and a 10 Hz low pass filter was applied to the

data by the SAMS unit prior to digitization. Prior to plot production, the raw SAMS data were

compensated for gain changes, and then demeaned. Demeaning was accomplished by analyzing

individual sections with a nominal length of 30 minutes. Users who are interested in further details for

either of these operations are encouraged to contact the PIMS group.

Color spectrograms are used to show how the microgravity environment varies in intensity with respect

to both the time and frequency domains. These spectrograms are provided as an overview of the

frequency characteristics of the SAMS data during the mission. Each spectrogram is a composite of six

hour’s worth of data. The time resolution used to compute the spectrograms seen here is 40.96 seconds.

This corresponds to a frequency resolution of 0.02 Hz.

In order to produce the spectrogram image, PSDs were computed for successive time intervals (the

length of the interval is equal to the time resolution). For the PSD computation, a Hanning window was

applied. In order to combine all three axes into a single plot to show an overall level, a vector

magnitude (VM) operation was performed. Stated mathematically:

VM PSD PSD PSD k xyz kkk = ++ 222 .

By imaging the base 10 logarithm (log10 ) magnitude as a color and stacking successive PSDs from left

to right, variations of PSD magnitude and frequency are shown as a function of time. Colors are

assigned to discrete magnitude ranges, so that there are 207 colors assigned to the entire range of

magnitudes shown.

The colorbar limits are chosen in order to minimize saturation in a given set of spectrogram plots. Data

which fall outside of these limits will be imaged as either the highest or lowest magnitude, depending on

which side they have saturated. If an area of interest seems to be saturated, care should be taken because

the actual values may lie above or below the color mapping shown on the plot.

Due to the nature of spectrograms, care should be taken to not merely read a color’s numeric value as

being the “amount” of acceleration that is present at a given frequency. In order to get this type of

information, the PSDs must be integrated between two frequencies. These frequencies (lower and

upper) form the band of interest. The result of this integration is the gRMS acceleration level in the

f f lower upper [ ] , band. The PIMS group is able to provide this type of analysis on a per-request basis.

Plot gaps (if any exist) are shown by either white or dark blue areas on the page. If a plot gap exists for

an entire plot (or series of successive plots), a comment is placed on the page to let the user know there

is a gap in the data. These “no data available” comments will not show exact times for which the data

are not available, but will only indicate missing plots.

Appendix D: SAMS Color Spectrograms for Unit G, TSH B

The PIMS group has processed SAMS data from STS-87, Unit G, TSH B to produce the plots shown

here. These data were collected at 250 samples per second, and a 100 Hz low pass filter was applied to

the data by the SAMS unit prior to digitization. Prior to plot production, the raw SAMS data were

compensated for gain changes, and then demeaned. Demeaning was accomplished by analyzing

individual sections with a nominal length of 30 minutes. Users who are interested in further details for

either of these operations are encouraged to contact the PIMS group.

Color spectrograms are used to show how the microgravity environment varies in intensity with respect

to both the time and frequency domains. These spectrograms are provided as an overview of the

frequency characteristics of the SAMS data during the mission. Each spectrogram is a composite of six

hour’s worth of data. The time resolution used to compute the spectrograms seen here is 16.4 seconds.

This corresponds to a frequency resolution of 0.06 Hz.

In order to produce the spectrogram image, PSDs were computed for successive time intervals (the

length of the interval is equal to the time resolution). For the PSD computation, a Hanning window was

applied. In order to combine all three axes into a single plot to show an overall level, a vector

magnitude (VM) operation was performed. Stated mathematically:

VM PSD PSD PSD k xyz kkk = ++ 222 .

By imaging the base 10 logarithm (log10 ) magnitude as a color and stacking successive PSDs from left

to right, variations of PSD magnitude and frequency are shown as a function of time. Colors are

assigned to discrete magnitude ranges, so that there are 207 colors assigned to the entire range of

magnitudes shown.

The colorbar limits are chosen in order to minimize saturation in a given set of spectrogram plots. Data

which fall outside of these limits will be imaged as either the highest or lowest magnitude, depending on

which side they have saturated. If an area of interest seems to be saturated, care should be taken because

the actual values may lie above or below the color mapping shown on the plot.

Due to the nature of spectrograms, care should be taken to not merely read a color’s numeric value as

being the “amount” of acceleration that is present at a given frequency. In order to get this type of

information, the PSDs must be integrated between two frequencies. These frequencies (lower and

upper) form the band of interest. The result of this integration is the gRMS acceleration level in the

f f lower upper [ ] , band. The PIMS group is able to provide this type of analysis on a per-request basis.

Plot gaps (if any exist) are shown by either white or dark blue areas on the page. If a plot gap exists for

an entire plot (or series of successive plots), a comment is placed on the page to let the user know there

is a gap in the data. These “no data available” comments will not show exact times for which the data

are not available, but will only indicate missing plots.

Appendix E: SAMS Color Spectrograms for Unit G, TSH A

The PIMS group has processed SAMS data from STS-87, Unit G, TSH A to produce the plots shown

here. These data were collected at 50 samples per second, and a 5 Hz low pass filter was applied to the

data by the SAMS unit prior to digitization. Prior to plot production, the raw SAMS data were

compensated for gain changes, and then demeaned. Demeaning was accomplished by analyzing

individual sections with a nominal length of 30 minutes. Users who are interested in further details for

either of these operations are encouraged to contact the PIMS group.

Color spectrograms are used to show how the microgravity environment varies in intensity with respect

to both the time and frequency domains. These spectrograms are provided as an overview of the

frequency characteristics of the SAMS data during the mission. Each spectrogram is a composite of six

hour’s worth of data. The time resolution used to compute the spectrograms seen here is 40.96 seconds.

This corresponds to a frequency resolution of 0.02 Hz.

In order to produce the spectrogram image, PSDs were computed for successive time intervals (the

length of the interval is equal to the time resolution). For the PSD computation, a Hanning window was

applied. In order to combine all three axes into a single plot to show an overall level, a vector

magnitude (VM) operation was performed. Stated mathematically:

VM PSD PSD PSD k xyz kkk = ++ 222 .

By imaging the base 10 logarithm (log10 ) magnitude as a color and stacking successive PSDs from left

to right, variations of PSD magnitude and frequency are shown as a function of time. Colors are

assigned to discrete magnitude ranges, so that there are 207 colors assigned to the entire range of

magnitudes shown.

The colorbar limits are chosen in order to minimize saturation in a given set of spectrogram plots. Data

which fall outside of these limits will be imaged as either the highest or lowest magnitude, depending on

which side they have saturated. If an area of interest seems to be saturated, care should be taken because

the actual values may lie above or below the color mapping shown on the plot.

Due to the nature of spectrograms, care should be taken to not merely read a color’s numeric value as

being the “amount” of acceleration that is present at a given frequency. In order to get this type of

information, the PSDs must be integrated between two frequencies. These frequencies (lower and

upper) form the band of interest. The result of this integration is the gRMS acceleration level in the

f f lower upper [ ] , band. The PIMS group is able to provide this type of analysis on a per-request basis.

Plot gaps (if any exist) are shown by either white or dark blue areas on the page. If a plot gap exists for

an entire plot (or series of successive plots), a comment is placed on the page to let the user know there

is a gap in the data. These “no data available” comments will not show exact times for which the data

are not available, but will only indicate missing plots.

Appendix F: PIMS USMP-4 Logbook

During the STS-87 mission, members of the PIMS team monitored mission events using voice

communication loops and video downlink. Items that were of interest because of the potential impact on

the microgravity environment were recorded in the PIMS logbook. An electronic copy of the logbook is

included in the CD-ROM version of this report.

Two accelerometer systems, the Orbital Acceleration Research Experiment and the Space Acceleration Measurement System, were used

to measure and record the microgravity environment of the Orbiter Columbia during the STS-87 mission in November-December 1997.

Data from two separate Space Acceleration Measurement System units were telemetered to the ground during the mission and data

plots were displayed for investigators of the Fourth United States Microgravity Payload experiments in near real-time using the World

Wide Web. Plots generated using Orbital Acceleration Research Experiment data (telemetered to the ground using a tape delay) were

provided to the investigators using the World Wide Web approximately twelve hours after data recording. Disturbances in the

microgravity environment as recorded by these instruments are grouped by source type: Orbiter systems, on-board activities, payload

operations, and unknown sources. The environment related to the Ku-band antenna dither, Orbiter structural modes, attitude deadband

collapses, water dump operations, crew sleep, and crew exercise was comparable to the effects of these sources on previous Orbiter

missions. Disturbances related to operations of the Isothermal Dendritic Growth Experiment and Space Acceleration Measurement

Systems that were not observed on previous missions are detailed. The effects of Orbiter cabin and airlock depressurization and

extravehicular activities are also reported for the first time. A set of data plots representing the entire mission is included in the

CD-ROM version of this report.
