In total, they closed out 18 C/O Mod Proposals and 8 ECPs. Four

additional C/O Mod Proposals (MSFC-213, 215, 216, and 217), Engineering

Change Proposal (ECP) 87, and our MSL-2 proposal in response to RFP 8- 

AP-32-MSL-2 were negotiated but not incorporated by SA at the period's

end.

Seven C/O Mods were received from MSFC, and we responded to

eleven C/O Mods, ten of which were received prior to the start of this

report period.

Responses are being prepared to seven C/O Mods at this period's

end; one ECP that will have a cost 'impact is in preparation. Thera are

currently 17 unnegotiated C/O Mod Proposals and 2 ECPs with a cost 

impact in the MSFC evaluation process.

WBS 05.2 - Information Management 

During this period, PMIC Information Management activities

resulted in the reproduction of 83,076 pages in support of various SPPO

and PMIC documentation requirements. We added 80 new documents to our

3-1

4. SPACELAB MISSION NO. I

WBS 75.0 - PAYLOAD INTEGRATION REQUIREMENTS

WBS 75.2 - MPE DESIGN

Design of additional flight stowage item mockups was completed.

Mockups will be fabricated and used in the PCTC during the SL-1 mission.

WBS 75.9 Ground 0 erations Analysis and Requirements Definition

We continued to support KSC activities through GIRD maintenance.

The Ground Operations employee assigned to KSC for SL-1 Mission Manager

support returned to MSFC.

WBS 75.11 - Configuration Change Coordination and Processing

During this period, we supported the SL-1 Delta Flight Readiness

Review (FRR). We compiled a listing of all changes processed through

the various configuration control boards (CCBs) subsequent to the SL-1

Phase 1I FRR. This listing was utilized by the FRR team in evaluating

the payload readiness for flight. We processed 14 engineering change

requests (ECRs) through the MSFC Level II CCB. Most of these changes

applied to requests for approval of late stowage items and included

approval of Revision E to the SL-1 stowage list. We processed a change

approving the SL-1 payload deintegration requirements which were incorporated into the SL-1 GIRD. We processed six field engineering changes

(FECs) which were implemented onsite at KSC.

We participated in the Joint Integrated Simulations at the JSC

POCC. This participation included the monitoring of the POCC terminal

in the Customer Services Room, the maintenance of an activities log, and

the maintenance of SPAN-CSR action requests. We forwarded these action

requests to the specified actionees.

WBS 75.13 - Integ rated Pa.vload ComDatibilit

The Mission Manager's payload integration support group at KSC

continued to support the payload activities. Primary tasks were

r

replacement of expendable SL-1 flight item;, impacted by the launch

delay, and review and updating of the SL-1 deintegration requirements

fi

based on updated guidelines, We arc also supporting the simulation

activities at the POCC and the HOSC in preparation for the November 28,

1983, launch.

WBS 95.0 - PAYLOAD FLIGHT OPERATIONS INTEGRATION

WBS 95.1 - Onboard Flight/Mission Operations

Launch date changes from September to October and finally to

November caused portions of the Payload Flight Data File (PFDF) to be

revised and put through the printing and fabrication process again.

These revisions required additional short-term effort, which we provided

to meet the delivery requirements.

We continued to support the Integrated Training/Proficiency

Training (IT/PT) that was rescheduled and conducted in October and

November 1983.

WBS 95.2 POCC Requirements

Four of the five remaining POCC cadre training simulations were

conducted at JSC and supported from the Huntsville Operations Support

Center (,?i .' and the Payload Crew Training Complex (PCTC). Joint Integrated 1 mulation (JIS) -04 was a 72-hour mission simulation, which

started on Monday, September 19, 1983. For the first time, virtually

all of the elements that will function during the mission participated

in the simulation. We prepared the MSFC simulation script and assisted

in the coordination of that script with the JSC simulation team. We

also participated in the debriefing of the simulation held on September

23, 1983, at which we presented the payload malfunctions that had been

included in the script for that simulation.

We participated in the conduct of 8-hour simulations on

September 28, 1983, and October 6, 1983. These were on-orbit simulations for which we coordinated the payload inputs to the simulation

script with JSC and participated in both the sim prebriefing and debrifing.

A 57-hour simulation, JIS-07, was conducted October 11-13, 1983.

Again, we prepared and coordinated the payload portion of the script and

9 

4-2

participated in the conduct of the simulation and the simulation

prebriefing and debriefing.

^. POCC Operations Training Documents (DR FI-05) were prepared and

delivered for Joint Integrated Simulations 02, 03, and 08.

3 The HOSC HRM Data Base was finalized and delivered on October

26, 1983,

f

WBS 95.3 - Payload Data Processing Requirements

We incorporated changes resulting from a meeting with the

iv

Principal Investigators in preparation for republishing the Spacelab

Data Processing Facility Requirements Document; Part I, and the Video

w*

Requirements Document.

We assisted Boeing in checking out modifications to the

Automated Data Requirements System (ADRS).

WBS 95.4 - Public Affairs Inflight Video a nd Photographic Requirements

We participated in the: four Joint Integrated Simulations

conducted at JSC during the reporting period by manning the TV Ups

position in the POCC.

The contents of the TV/Photo Ops Book were continually changing

Jill

throughout the reporting period. Revision A to the final document was

delivered on September 30, 1983. Changes to this issue were in progress

at the close of the reporting period.

The last payload crew training on TV operations was conducted in 

the PCTC using flight type TV cameras and associated equipment.

The following parts/materials were delivered during this report

period:

® Twenty-five electrical cables to KSC

o Cable markers and lacing tape to KSC

0 Two RAU mounting brackets to MSFC/MDTSCO

® MLI material to the University of Iowa

© Two connectors to the Naval Research Laboratory.

MLI

The following MLI blankets are in work at Sheldahl:

0 Experiment 6

0 Coldplates 1 and 12

® Experiment 10 electronics.

Our manufacturing division has been authorized to fabricate the

coldplate MLI tent frames. The 2219 aluminum tubing specified on the

drawings could not be obtained in time to meet any reasonable delivery

schedule; therefore, 6061 aluminum tubing was ordered for this job and

is Lxpected not later than November 21, 1983. The work will then proceed and delivery should be complete not later than December 23, 1983.

Cables

Of the 54 MPE cables in work, 23 are at KSC, 12 are at MSFC for

baking, 9 are in fabrication, and 10 are on hold for various reasons,

i.e., awaiting; connectors baking; 2 EOS from MSFC; and GFE connectors

from MDTSCO. Fabrication of the three VFI cruciform cables will begin

upon receipt of tie wraps and wire.

The PCA modifications are ii, work and will be complete not later

than December 9, 1983.

5-1
WBS 75.0 - PAYLOAD INTEGRATION REQUIREMENTS

WBS 75.2 - MPE Final Desia

Meetings were held with the Experiment 10/11 instrument

developer to review new insulation requirements for the HRTS telescope

and the status of the design for the additional radiator area on the

SUSIM instrument. An additional meeting was held at NRL to examine the

hardware and trial fit the insulation designs to the flight hardware.

The results of this meeting require some redesign of the HRTS aperture

door blankets and a new start on the SUSIM designs. These changes will

necessitate an approximate 3 to 6 weeks slip in design baseline and

release for fabrication.

The PCA design documentation was updated during this period to

incorporate the new ESA/DS clamp unit actuation system design and add

interface provisions to the PCA assembly fixture for the new ESA/DSprovided X-struts: This PCA assembly documentation and associated Part

I and II CEI specifications, materials lists, and associated analyses

will be submitted for MSFC Level II baseline on or before November 21,

1983.

WBS 75.9 - Ground Operations Analysis and Requirements Definition

For SL-2, we are preparing the initial release of the deintegration requirements for early review submittal on December 14, 1983. GIRD

maintenance for SL-2 is continuing.

WBS 75.10 - Safety and Quality Assurance

Trips were made to experiment developer facilities on Experiments 3, 7, and 9 to acquire data for the ground and flight safety data

packages. The GSE/ECE Ground Operations Data Package was updated to

Phase III status and submitted for MSFC review. There are still many

open items which will be closed after receipt of GFE data. We prepared

Acceptance Data Packages (ADPs) and held Acceptance Reviews for 25

cables.

5-2
WBS 75.11 - Configuration Change Coordination and Processing

We continued to process ECRs and ECPs against SL-2 baselined

documentation. This effort required the preparation of PCN folders, the

tracking of the change data in the SCIT, the distributiLl of change

evaluation requests, and the preparation and processing of CCB directives for SL-2 changes submitted to SPPO. We published a weekly SL-2

Open Action Report, K014, and a TBE Drawing Release List (DRL) which

reflects all SL-2 MPE CEIs being built by TBE.

We submitted for MPE Project Office review the SL-2 blanket

drawings for Coldplates 5, G, 8, 9, and Experiment 10, and released the

following SL-2 ECPs to SPPO:

the SL-2 IIAs and submitted for distribution.

WBS 75,,13 - Integrated Payload Compatibility

The PCA Verification Requirements Document (DR IR-28) and Mass

Properties Report were updated to incorporate the new PCA actuator

system, new ESA parts, and revised JA-061 requirements.

An IPRD ECR was developed and submitted to revise the weight

allocation for Experiment 9.

The initial structural verification package from Experiment 14

was reviewed. Discrepancies in the package were discussed with the

experiment developer via telecon. In addition, three trips were taken

to experiment developers' facilities (Experiments 3, 7, and 10) to

review progress and discuss how to complete an acceptable verification

package.

We also initiated a review with MSFC of weld X-rays for Experiment 10. Portions of the welds were found inadequate and the developer

was asked to correct the problem. Additional dynamic analysis of

Experiment 6 was performed to resolve questions posed by MSFC S&E.

We initiated the task of updating the SL-2 Cruciform/PCA NASTRAN

dynamic model for use in a "basedrive" analysis to validate design load

factors. Fracture Control Plans were completed for Experiments 1 and 9

and were submitted to the Fracture Control Board. In addition, a

preliminary fracture screening was performed for Experiment 7 and the

fracture analysis begun.

The Fracture Control Plan for the PCA was updated during this

report period and submitted to design for analysis.

WBS 35.0 - SUPPORT SYSTEM DEVELOPMENT

WBS 35.1 - Mission Peculiar Equipment MPE

Hardware

SL-3 MPE hardware fabrication and mockup fit-checks have

proceeded on a "fast as possible" basis during this period. Fabrication

completion, testing, and shipment of the Racks 6, 9, and 11 hardware

were accomplished by September 30, 1983, with very few open items.

Design revisions and engineering changes have resulted in the addition

of several items to be shipped to KSC. These remaining items will be

shipped on or about November 18, 1983.

Fabrication completion of Rack 4 MPE was accomplished on

November 7, 1983. Mockup buildup is being accomplished at this time

with completion to be November 21, 1983. Rack 4 flex hoses have not

been received as of this date and progress is being hampered by fitcheck problems (i.e., ground rack not built to SPAH specifications).

Shipment of Rack 4 MPE will be delayed until the end of November.

ESS assembly piece part fabrication and buildup has proceeded

ahead of schedule. MPESS, payload adapter, utility bridge, and

experiment mounting assemblies are complete and are being integrated at

this time. Minor problems have occurred during fit-check but are being

resolved.

Underfloor MPE hardware fabrication was completed November 4,

1983, and mockup buildup will begin shortly (emphasis has been placed on

Rack 4 and ESS to date). No major problems are foreseen on this

assembly, assuming flex hoses arrive and fluid flow tests can be

accomplished in a timely manner.

Rack 3 MPE started the fabrication cycle the end of October.

Hardware consists principally of reinforcing angles, shims, closure

panels, cables, and attachment hardware.

Vacuum vent MPE hardware has been on hold because of emphasis on

other assemblies, and no measurable progress was made during this

period. Approximately 50 percent of this hardware is completed and

6-1
shipment on December 16, 1983, should not present a problem once other

assemblies are finished and work can proceed.

We completed MPE verification forms for the MPE hardware and

processed verification data for Racks 4, 5, 6, 7, and 11.

Cables

The six cables for Rack 11 were shipped to KSC on September 30,

1983. All other cable fabrication is awaiting cable lengths, which are

to be determined the week of November 16, 1983.

Documentatio n

The 0&M Manual for the Module Rack 4/Underfloor Fluid Loop was

completed and delivered on schedule on November 10, 1983.

WBS 75.0 - PAYLOAD INTEGRATION REQUIREMENTS

WBS 75.1 - Configuration Design Definition

Conceptual layouts and feasibility studies were prepared for

adding the SL-1 metric camera, galactic wide field camera, and an additional MPESS to the SL-3 payload.

experiments were also reviewed, and comments were submitted with closure

action.

Studies were initiated to identify and assess the impact of

inclusion of the Very Wide Field Camera experiment as part of the SL-3

payload. This included consideration of the power and energy budget,

cable interface requirements, and mission timeline. Proposed changes in

mission sequence testing were coordinated with TOE personnel at KSC.

WBS 75.7 - Structural/Mechanical System Integration

We completed checking of the payload bay and underfloor MPE

analysis for verification. We also completed analytical verification of

all MPE in Rack 4, the payload bay, and the underfloor area. We

reviewed approximately 25 structural/mechanical verification items submitted by the experiment developers.

We participated in an analysis to determine the impact of adding

additional experiments to the mission. The Fracture Control Plan for

MPE was revised to include Racks 5 and 7 MPE and revisions to the SL-3

payload bay ESS. A fracture control problem with the DDM experiment

hinge pins was also resolved.

WBS 75.8 - Pointing Stabilization Systems Integration

We participated in a study to evaluate two alternate orbital

attitudes for the SL-3 mission. The study determined how many additional VRCS thruster firings would be required for each alternate attitude compared to that predicted for the gradient attitude. A second

output of this study was the line of restrictions for ATMOS for 360-

degree viewing.

WBS 75.9 - Ground Operations Analysis and Requirements Definition

We supported and participated in the SL-3 Prelevel IV Coordination Meeting at KSC during September 21, 22, 23, 1983. The initial

release of the SL-3 deintegration requirements was submitted on

September 17, 1983, 7 weeks ahead of the scheduled date of December 2,

1983. We have also provided a Ground Operations employee for SL-3

Mission 11anager support at KSG beginning November 4, 1983. GIRD maintenance and coordination activities are continuing at MSFC.

WBS 75.10 - Safety and Quality Assurance

The GSE/ECE Ground Operations Safety Compliance Data Package was

updated to Phase III and submitted to MSFC for transmittal to KSC. The

chase III Safety Review has been scheduled for November 15, 1983, and

review materials are currently being developed. We prepared ADPs and

held Acceptance Reviews on Racks 6, 9, and 11.

WBS 75.11- Configuration Management

SL-3 Configuration Change Coordination and Processing activities

during this period required extensive change processing coordination

with the MSFC Level II and the PMIC/TBE Level IV GCBs. We supported

MSFC Level 11 CCB meetings on September 27, 1983, and October 27, 1983.

This support included the preparation and distribution of the agendas

and minutes for these meetings and the preparation of Level II CCB

Directives (CCBDs) reflecting the board dispositions of the change

requests considered during these meetings. The September 27, 1983,

Level II CCB agenda included 19 scheduled change requests and 2 walk-on

change requests. We prepared and coordinated 12 Level II CCBDs reflecting Level 11 CCB dispositions which included the baselining of the MICG

and ARCLSP IIAs and board direction for PMIC/TBE issue of Revision B to

the SL-3 IPRD. Support for the PMIC/TBE Level IV CCB encompassed the

preparation of Level IV CCBDs approving 6 SL-3 MPE drawing revisions,

baselining 17 SL-3 MPE drawings, and approving engineering change orders

(ECOs) against previously baselined SL-3 MPE drawings.

We provided the drawings, parts lists, and outstanding ECOs

required to assemble the acceptance data packages for SL-3 Racks 6, 9,

and 11.

We continued to process and track actions to close DNs submitted

against the various milestone review data packages and published

periodic reports reflecting open DN actions. We published on a regular

basis reports reflecting SL-3 baselined documents, open change activities, and TBE released drawings.

WBS 75.13 - Integrated Payload Compatibility

ECR TBE 3-0169 was approved with modification by the MSFC Level II

board. We supported the DDM IRR on Se p tember 29 with updated verification

status, and processed over 150 other instrument verification packages.

The following SL-3 MPE materials lists were submitted to MSFC:

Racks 4, 5, 6, 7, and 9. The materials list for Rack 11 siould be submitted shortly. The following SL-3 PI experiments were coordinated with

the MSFC Materials Laboratory: MICG, ARCLSP, GFFC, and DDM. Numerous

drawings and ECOs were reviewed for various MPE programs to ensure that

the materials called out on these documents meet the design requirement of 

toxicity, flammability, stress corrosion, etc.

WBS 75.14 - Mass Properties

The mass data base was updated in preparation for the Mass Properties Quarterly Report scheduled for November 30, 1963. We assisted in the

stowage analysis effort and supported verification item reviews on instrument hardware. Mass data was provided for racks that have been shipped to

KSC.

the support stand assembly for the OAST-1 DAE was completed, and the

final drawing (G4-60372) was issued.

A final issue of the MSL-1 Metallic and Nonmetallic Materials

List (DR IR-36) was issued. An EGO to MSLi-1, MPE drawing (F4-30594) was

issued to facilitate the GAS Can Insulation Blanket. A feasibility

study was initiated to add a materials mounting plate to the MSL-1 payload.

An MPESS Shipping Cradle Tent Stand was designed and analyzed. 

The second GFE Interdyne tape recorder was received for MEM on

November 8, 1983. Prior to formal acceptance by the government, the

tape recorder was tested at the TBE facility. The test indicated the

recorder was operational in both read and write modes. The first

recorder will be sent to Interdyne for refurbishment after Interdyne

receives a new four-track head.

The MEM PC board was received from the vendor. The board components were mounted and board testing was completed. Numerous artwork 

errors were found and corrected by the use of green wire techniques. 

The prototype board is now operational.

The MEM modification of the SEP enclosure started. The card

gauge and brackets are complete.

The MEM software was completely tested. The fast tape rewind 

(120 IPS) was replaced with the fast search (40 IPS) rewind. This was

necessary because of the removal of the head disengagement capability. 

7-2
WBS 75,4 - Command and Data Requirements

We participated in a telecon with the OAST-1 MSFC Payload Operations Working Group during review of PIP Annex 3, Flight Operations

Support Annex. Discussions included clarification of commands and

applicable end item feedback for DAC, SAC, and SCCF. We reviewed Change 1

to PIP Annex 4, Command/Data and corrected nomenclature for OAST-1 use of

the FMDM pulse output discrete. A Data Change Request (OCR) is being

written by Dick Welch at JSC.

WBS 75.5 Environmental System Integration

Additional analyses and coordination were performed to resolve the

thermal problem with the OAST-1 SAE tape recorder. A thermal problem with

the OAST-1 SCCF was resolved. Thermal isolation is being added between

the SCCF and the MPE. Additional analyses of the OAST-1 PCB were completed and a technical memo prepared.

WBS 75.7 - Structural/Mechanical Systems Integration

The OAST-1 integrated payload model was updated to the latest SAE

mass and CG. A copy of the model was sent to John Sunkel at JSC as

t

requested by MSFC. The OAST-1 Fracture Control Plan for the SAE experiment was completed and submitted to the Fracture Control Board for review.

WBS 75.8 Pointing/Stabilization Systems Integration

We continued the task to resolve u.,ST-1 ON 2-452-2873. We validated new aerodynamic data (bay doors open) that was received earlier from

Review conducted with KSC on October 25, 1983. The OAST-1 GSE/ECE Ground

Operations Safety Data Package was updated to Phase III status and submitted to MSFC for review prior to submittal to KSC.

We prepared ADPs and held Acceptance Reviews on the OAST-1 thermal

isolators and MPESS SN 004 and its associated GFIE.

WBS 75.11 - Configuration Change Coordination and Processing

We concluded processing changes against the OSTA-2 baseline with

the approval of ECP 94F. This ECP completed the incorporation of outsttnding ECOs into the OSTA-2 Cable Assembly Drawings to reflect as-built

configuration.

We continued to process all ECRs and ECPs against the current

OAST-1 and MSL-1 baselines. This effort required preparation of PCN

folders, processing of change evaluation requests, tracking changes in

SCIT, and preparation of CCBDs. We published weekly a partial payload

open action report, K32A, which lists all outstanding open actions against

DAST-1 and MSL-1 baselined documentation.

We continued to track OAST-1 and MSL-1 DN open actions and published each month the open actions in the partial payload DN SCIT Report,

K062.

We baselined the OAST-1 IPL Verification Plan, JA-148, and the

Cable Interconnect Diagram and Electrical System 5chgmatic. The following

OAST-1 ECPs were released to SPPO.
7-5

All OAST-1 drawings and CEI specifications have been baselined

except the OAST-1 Thermal MPE Part II CEI Specification and the OAST-1

Payload Installation/Assembly Drawing, F4-10030.

We baselined the MSL-1 Ground Integration Requirements Document

(GIRD), JA-143.

We submitted the MPESS (SNs 003 and subsequent) Operations and

Maintenance Manual, PMIC-0&M-3864, for S&E review and evaluation prior

to baselining.

During this period, we baselined and submitted for MSFC evaluation the ADSF Middeck Electronics Module Assembly and associated drawings and processed 14 Class II ECOs through the TBE/PMIC Level IV CCB.

We distributed these baselined drawings and ECOs for the manufacturing

effort and submitted these documents to the MSFC Documentation Repository.

We continued to process and track ON closeouts against the ADSF,

ARC, and IEF milestone review data packages and to process change

requests submitted by MSFC organizational elements. We published on a

regular basis reports depicting ON and open chanae activities.

WBS 75.12 - Interface Agreemer- s

The CCB meeting held on October 18, 1983, included the review of

ECRs to the DAE and SAE IIAs. Action was deferred on all submittals

presented. 

WBS 75.13 - Integrated Payload Compatibility 

We attended the OAST-1 POWG telecon with JSC on November 2,

1983. The latest OAST-1 timeline was reviewed and data was presented to

support the MSFC proposal to allow VRCS maneuvers with the SAE array at

70 percent deployment. JSC subsequently agreed to this operation which

will significantly decrease the number of deplo yments on the array.

Several ON closeouts were submitted and several previously submitted closeouts were approved. Most of the remaining open issues 

relate to thermal analysis, GSE for handling MPE and experiments, and
pointing and stabilization, including alignment. Most of these issues

are being actively worked.

We supported a 2-day MSFC working group meeting to review the

procedures in the Flight Operations Support Annex and the STS crew

checklist.

In a followup telecon with JSC and Rockwell representatives on

the changes to the connectors at the SIP interface, it was agreed that

TBE would revise the MPE cable connectors and JSC would provide hardware

to support this change.

The SCCF interface plate was received at JPL and a fit-check of

the actual hardware verified the interface compatibility.

A potential thermal problem with the SCCF surfaced and several

telecons resulted. The present approach will be fur TBE to provide four

thermal isolators as MPE to go between the SCCF interface plate and the

SCCF support brace. Low emissivity thermal tape will also be provided

by Jr^L and applied to both sides of the SCCF interface plate by TBE.

We attended and participated in regularly scheduled OAST-1 payload working group meetings at MSFC. Although no definite guidelines

have been provided by MSFC with regard to tethered connector caps, we

have provided an attach point for SAE test connector cable covers for J3

and J7 test connectors.

At the direction of the Mission Manager, we furnished Lockheed

with silverized Teflon thermal tape to wrap the SAE tape recorder.

We attended the OAST-1 Phase II Safety Review telecon with KSC,

which reviewed the ground operations hazard analyses and safety compliance. Plans are to install the SAE NSI pyros in the 0&C Building at

KSC.

SAE verification is continuing after the IRR with open items

being closed now. The final stress analysis was received from LMSC during this reporting period, and verification requirements which were

awaiting receipt of the analysis are being worked. Several waivers on

the SAE pyrotechnique system have been progessed, but final approval has

not been received on the JSC-imposed requirements.

7-6
The SCCF IRR was held October 13. The review was very good with

only seven items being included on the Open Items List. One of these,

the GSE proof loading, has been closed with the remaining ones to be

closed nearer the time to ship to KSC.

The DAE IRR is now scheduled for December 20, with the associated documentation delivery on December 1. The primary delay in the

DAE IRR scheduling is completion and documentation of hardware testing.

The Integrated payload verification has begun with all requirements which can be satisfied by GIRD paragraphs having been sent to NASA

for evaluation. Twelve of the integrated payload verification requirements cannot be worked until the DAE data is received. The remaining

folders are being prepared for delivery to NASA.

OAST-1 MPE acceptance reviews have been rescheduled as follows:

® Electrical - December 20

o S/M - December 7

® Thermal - December 7

Manufacturing route sheets are being accumulated for support of these

Acceptance Reviews.

The MEA-A2 (instrument) Verification Plan has been received, but

the similarity statement necessary to close most of the requirements has

not.

The Interface Verification Summary Report for the SAE experiment

was completed and submitted to SPPO on September 21, 1983. The Inter- , 

face Verification Summary Report for the SCCF experiment was completed

and submitted to SPPO on October 13, 1983.

On September 20, 1983, PMIC personnel met with the MSFC Fracture

Control Board to discuss PMIC Fracture Control Plans, The MSFC Fracture

Control Board stated in this meeting that visual inspection would no

longer be acceptable for detecting surface defects. The subject PMIC

control plans were revised to incorporate this requirement and resubmitted to the Board. The MSL--1 Fracture Control Plan has been approved

by the MSFC Fracture Control Board.

WBS 75.2 - MPE Design

During this reporting period, detail design work in all areas of

the Astro-1 project proceeded rapidly. By the end of the period, 118

drawings had been delivered to checking and 25 drawings have either been

baselined or are in the process of being baselined. Critical drawings

which were baselined are the cruciform envelope drawings.

Astro design personnel supported an Astro Clamp Status Review

which was held at Rockwell, Downey.

All design-related DNs which were scheduled to be closed during

this period were closed out.

Thermal analyses of the cruciform, Integrated Radiator System

(IRS), and PCA continued during the period. The cruciform thermal model

is being updated to reflect post-PDR design changes. The sensitivity

study was completed and the results were presented to MSFC. A tentative

8-1
decision was made to place heat pipes on the cruciform. The final

decision was delayed pending the completion of additional analyses to

determine the improvement to be expected from adding heat pipes.

Updating of the IRS thermal model and simulation of the design cases

were completed. Evaluation of the heat pipe proposals was completed and

selection of a vendor is expected by November 25. Development of the

thermal model of the PCA continued. Calculation of form factors, gray

bodies, and radiation constants will begin by November 12.

Stress analyses of 4he alignment holding fixtures, alignment

simulators, and the cruciform envelope drawings were completed during

this period. Continued stress and dynamics work on the IRS and the OSP

mount plate has resulted in a number of required design changes which

are being implemented in the IRS and OSP mount drawings. Increased

weight in the instrument electronics boxes supported by the IRS and in

the MSFC-designed OSP Sun shade baffles was the primary cause of the

required redesign efforts.

Deflection analyses of the cruciform-mounted instruments were

done in support of the thermal sensitivity analyses for on-orbit alignment and stability. Basedrive efforts were begun on the cruciform and

PCA. Cruciform, PCA, and OSP analyses are proceeding on schedule.

The cruciform, PCA, and IRS Part I CEI Specifications were

reviewed, finalized, and delivered to MSFC for baselining on October 28.

Preliminary layout and design work was begun on the Astro MLI and cable

routing drawings.

During this period, work proceeded rapidly on the detail design

drawings for the Wide Field Camera (WFC). Several issues raised during

the informal PDR process were resolved. Thermal and stress models are

under development for the camera canister and a thermal model for the

camera electronics box is well underwa

were verified. We designed a new RAU serial command receiver circuit

with a lower parts count and higher reliability. A critical pulse

transformer component, which replaces 22 previous components, was

located in MSFC AGS surplus stock in both flight and breadboard form. 

The analog/discrete interface breadboard wirelist and layout is 90 percent complete. We plan to provide a wirelist and component layout to

the technician for wirewrap. PDR schematics were updated to show correct Dual In-line Package (DIP) mounted resistors and capacitors. We

provided a copy of MSFC-SPEC-521A to Tempo for EIU power supply design.

We completed checkout of the Avionics Development Facility (ADF) RAU

serial command simulator to be used to test the WFC Electronics Inter-

face Unit (EIU) RAU serial receiver. The RAU simulator uses the OPAA

prototype and Starplex firmware. We also placed orders for 90 percent 

of the EIU flight parts.

WBS 75.6 - Electrical Systems Integration

A design modification of the Astro-1 VFI thermal sensing system'

was initiated to improve the accuracy of cruciform temperature measurements. Vendors were contacted to establish price and delivery estimates

The CEI Specification Part I for the cruciform, IRS, and PCA,

and also the Systems Requirements Document were provided to MSFC on

October 28, 1983, as contract deliverables.

Revision "C" of the MPE Development Plan was distributed to all

Astro-1 team members and included the latest changes from an MSFC review

as well as revised schedule dates for certain MPE and GSE items.

An MPE development schedule was developed and distributed to the

Astro-1 team and includes a schedule for each item of MPE and GSE and

for test equipment requirements. Schedules are provided on the following pages.

The preliminary results from the deploy restow analysis were

presented to MSFC and a recommendation was made to adjust the relationship of the clamps to the IPS to ensure restow under worst case conditions. No Criticality I safety failure modes were identified for the

PCA configuration and deploy/restow sequences. Areas were identified

where data inputs were not firm, particularly in regard to IPS

characteristics. This analysis will be updated as thermal modeling is

sufficiently complete on the PCA/pallet and as the IPS characteristics

are better defined. The systems-level FMEA analysis results are

continuing to be evaluated and studied for contingency operations as

these analyses are performed.

A presentation was made to the principal investigators in a

telescopes and between the OSP and the HUT telescope. This was a key

meeting where MSFC and the PIs agreed on pointing accuracy and stability

goals.

The cruciform thermal stability sensitivity analysis was completed for 10 parametric cases and was presented to MSFC. A recommendation was made to add five heat pipes to the cruciform to improve thermal

stability and thereby improve the probability of meeting the 2-arc-sec

stability goal between the OSP platform and the telescopes. Coalignment

between telescopes and stability between telescopes will also be

improved by addition of the heat pipes.

A set of design weights was developed to establish the load

carrying capability of the IRS, the cruciform, and the PCA. These

design weights were approved by the Mission Manager and were included in

the CEI specifications. Biweekly weight reports were also submitted to

MSFC in which comparisons were made between estimated current weights

and MPE limit weights. The latest report showed the TBE MPE limit

weight to be exceeded by 206 kg.

DNs written against the MPE PDR data package have continued to

be worked. Most of the ones remaining open are to be closed with the

release of the CDR data package in January. A summary of DN status

follows:

GENERATED WITHDRAWN CLOSED OPEN

132 14 76 42

The IPRD is under revisior from RIDS written during the IPL IDE

review. Only two RIDs remain open, and that is because required data

was not received from MSFC.

All WFC PDR comments were incorporated into the documentation

and change pages were sent to MSFC.

Verification and test planning has continued in many areas.

following plans were submitted to MSFC for review:

o Instrument Alignment Plan

® IRS Acoustic Test Plan

8-13
6 IRS Thermal Vacuum Test Plan

a Pallet/PCA/Cruciform Alignment Test Plan

e UIT Instrument Verification Plan

0 NUT Instrument Verification Plan

WUPPE Instrument Verification Plan.

The WFC Test Plan was developed and is going through review by

TBE.

The use of two Spacelab pallet engineering models in the Pallet/

PCA/Cruciform Alignment Test was proposed by MSFC and is being evaluated. The special GSE and facilities required to make use of these in

lieu of special fixtures are being identified and evaluated. The

results of a preliminary assessment were forwarded to MSFC.

The requirements for use of MSFC optical instruments, ATM Clean

Room in Building 4708, cranes, and support personnel as a part of the

Astro-1 instrument alignment verification was coordinated and submitted

to MSFC.

The canister for the WFC was evaluated and reclassified as a

sealed container to eliminate the unnecessary safety requirements for

pressure vessels.

9. PREMISSION DEFINITION

TD-JA02-83-02, dated June 9, 1983, authori,ad the performance of

the MSL-2 Premission Definition Study. This study activity consists of

the initial payload integration work on the MSL-2 mission. It is

reported below in WBS sequence.

WBS 35.0 - SUPPORT SYSTEM DEVELOPMENT

WBS 35.1 - Mission Peculiar Equipment (MPE)

Fabrication of the MPESS SNO06 piece parts is 75 percent complete. Long-lead electrical connectors for MSL-2 and the Experiment

Apparatus Containers (EAC) were ordered.

Our Manufacturing Division is presently estimating manhours and

material costs for fabricating seven EACs for inclusion in our EAC proposal which is being prepared.

WBS 75.0 - PAYLOAD INTEGRATION REQUIREMENTS

WBS 75.1 - Configuration Design Definition

The MSL-2 work emphasis this reporting period was on preparing

the initial configuration design layouts for the MSL-2 configuration

leading to a preliminary design review on December 5, 1983. A 6-week

delay in drawing production was encountered due to the design change

from the ESA coldplate to the Rockwell coldplate. The assembly and

installation drawings being prepared for the December 5 PDR are approximately 85 percent complete.

WBS 75.2 - MPE Design

Approximately 95 percent of the MSL-2 MPE design drawings are

complete and will be presented at the PDR on December 5, 1983. The EAC

drawings and the EAC CEI Part I Specification are complete and will be

distributed for NASA review on November 16, 1983.

The SCU housing design was also completed during this reporting

period.

9-1

l
The System Control Unit (SCU) CCI Part I Specification was

released for formal baselining.

During this period, two SCU working group meetings were

attended. The first meeting, held on October 27, 1983, introduced the

SCU and its role in MSL. The status of the SCU, including individual

board design status and parts procurement status was discussed. The

second meeting was held on November 8, 1983, and the status, schedule,

and parts selection were discussed.

During the period, the SCU schedule was revised to reflect

changes in requirements since initial schedule definition. The impact

of the requirements changes resulted in a 2-week delay in delivery of

the flight unit, from June 1, 1983, to June 15, 1983. This delay does 

not impact the MSL system delivery date.

On October 5, 1983, a presentation was given to the EB lab on 

the SCU software. This presentation included a software requirement

overview, a review of the software architecture, and the development

approach. The software requirements for both the SCU and SCU GSE are

being documented with a Software Requirements Review scheduled for

November 21, 1983. 

On October 20, 1983, a presentation on the SCU was given to NASA

Headquarters personnel during their visit to MSFC. The use of SCU in

MSL, its hardware and software architecture, and the flexibility in

general of the SCU were discussed.

WBS 75.3 - Command/Data/Communications Systems Integration

We completed a schematic for the Buffered Serial/Digital I/O

(BSDIO) module including standard multibus interface. The parts list

was modified based on this schematic design and was provided to TBE 

manufacturing.

WBS 75.5 - Environmental System Integration

The following thermal analyses are in process for the MSL-2

MPE/PDR:

a Pressure Drop Analysis

e Heat Load Analysis

9-2
e Accumulator Analysis

* Leakage Analysis.

The geometric model of the MSL-2 payload is complete and runs

are now being set up to calculate form factors, gray bodies, radiation

constants, and heat fluxes.

Inputs for the IIAs were completed and input for the IPRD is

being developed.

WBS 75.6 - Electrical System te Integration

The development of an MPE PDR data package was initiated with

the submission of inputs to the three experiment IIAs, PIP Annex 6, the

Unique ICD, and the Integrated Payload Requirements Document. An electrical part for CEI specification was developed and submitted for inclusion in the overall systems specification.

An initial MSL-2 Cable Intel~connect Diagram (CID) and an end-toend electrical system schematic were drafted for review. The

development of a generic MSL CID and schematic was initiated based on an

explanation of the MSL-2 documentation.

Cable design drawings with associated pars and materials lists

are being developed as system design progresses.

WBS 75.7 - Structural/Mechanical Systems Integration

The MSL-2 stress analyses for the EACs, SCU, and the ETR are

complete.

The MSL-2 basedrive analysis is in the data reduction phase.

All lift-off and landing load cases have been run. Current efforts

involve tabulating the results from each case to determine the maximum

accelerations.

The NASTRAN models (dynamic and stress) for the MSL-2 experiment

and subsystem payload adapters are complete. Hand analysis of the

bolted connections are 40 percent complete. The analysis for the MSL-2

generic integrated model is complete. The analysis for the MPESS modification is 60 percent complete.

9-3
WBS 75.9 - Ground Ooerations Anal y sis and Req uirements Definition

We are proceeding with the ground operations analyses and

requirements definition as planned. We are preparing the GIRD for FDOR

data package release on February 13, 1984.

WBS 75.10 - Safety and Quality Assurance

Trips were made to each of the MSL-2 experimenter facilities to

explain the type of data required and obtain information to enable

development of a safety data package to support flight safety. Hazard

analyses were performed and a Phase I Safety Data Package developed for

review by MSFC, MSFC comments were received and will be incorporated

for submittal to JSC during the next report period.

WBS 75.11 - Confi q uration Chang e Coordination and Processin

We supported activities resulting from the MSL-2 IPL RR. We

prepared and publi c `,ed on September 20, 1983, the minutes for the

September 16, 1983, MSL-2 IPL RR Preboard Meeting. The Preboard dispositioned all UNs submitted against the IPL RR data package and recommended that the Mission Manager cancel the IPL RR Board meeting scheduled for September 28, 1983. We prepared and distributed on September

26, 1983, a Mission Manager memorandum advising the Board members of

this cancellation.

We entered into our tracking system the 89 DNs against the IPL

RR data package. These inputs reflect the Preboard dispositions and the

individuals/organizations responsible for closing assigned actions. We

publishej' on a regular basis reports depicting the status of open DN

actions.

WBS 75.12 - Interface Agreements

The three MSL-2 IIAs were revised and submitted to SPPO on 

October 12, 1983. These revisions included the closures of the outstanding Requirements Review DNs.

9-4 
On October 14, 1983, we participated in a working group meeting

at the General Electrical Company facility. On October 20, 1983, we

participated in a working group meeting at JPL.

The inputs to the STS/Payload Unique ICD-A-18425 were completed

and submitted to SPPO on October 4, 1983. Annex 1 to JSC184?5 was also 

updated and submitted to SPPO on October 4, 1983.

We participated in an MSL-2 working group meeting at JSC on

October 12, 1983, to clarify and establish the requirements contained in

the Annex 1 to OSC18425 and the STS/Payload Jnique ICO-A-18425.

We received a redlined copy of the MSL-2 STS/payload IGO on

October 21, 1983. This redlined copy was produced during the working

group meeting at JSC on October 12, 1983. The document was again

updated (redlined) and submitted to SPPO on November 1, 1983.

W6S 75.13 - Integr ated Payload Compatibility 

On October 3, 1983, SPPO made the decision to use the Rockwell

coldplates instead of the ESA coldplates for the MSL-2 payload. This

change caused a 6-week slip in the MSL-2 schedule. 

The MSL-2 Payload Integration Plan (PIP) was redlined and

submitted to SPPO on October 5, 1983. On October 6, 1983, we supported

a telecon with JSC to discuss these MSL-2 PIP changes. The Annex 6 to

JSC18425 was updated and submitted to SPPO on October 4, 1983.

On October 12, 1983, we participated in a working group meeting

at JSC to clarify and establish the requirements for the MSL-2 payload

as it pertains to the PIP and Annex 6.

A preliminary listing of the GFE for the MSL-2 payload was given

to SPPO and SPO (Mr. G. Hawkins and Mr. E. Noel) on October 7, 1983.

The official request for the GFE for both flight and ground use was

submitted to SPPO on October 26, 1983.

The Preliminary Mission Implementation Agreements for the three

MSL-2 experiments (ADSF, EML, and 3AAL) were completed and submitted to

SPPO on November 1, 1983.

9-5
The Part I CEI Specification for the Systems Control Unit '5CU)

was submitted to MSFC for baselining on November 3, 1983.

WBS 75.14 - Mass Proaqrtjes

The MSL-2 mass control data has been included in the IPRD. A

Mass Properties Report remains in the preliminary phase of dev(Jopmont

until a configuration drawing is made avallaole.

TO-JA02-83-01, dated September 20, 1983, authorized the 43S 05.5

Shuttle High Energy Astrophysical Laboratory (SHEAL) study.

The concept for the SHEAL, originally developed undor this task

and reported on at Goddard Space Flight Center on July 6, 1983, vja,

further defined during this period. Major design issues aysoci(it,!t] with

development of the two-axis pointing system for use with BSXRT (Ind LAMAR

were addressed and total resource use estimates were refined. As a

result of these analyses, a more detailed mission concept was d(..'.riv,,d

and a higher confidence cost estimate for integrating the mission way^

generated. Space Data Corporation under subcontract, developed a

concept for a two-axis system which would provide the required pointing

accuracy and carry launch and landing loads with an axially Mounted

brake system. A concept for instrument mounting to the two-axis system

was defined and the use of a GSFC-provided star tracker and gyro system

was investigated for providing pointing information for the system. The

results of the study were presented to the GSFC Mission Management team

on October 26, 1983. This presentation and the distribution of the

associated documentation closed out the activities under this task.
