NEW COSMIC BACKGROUND EXPLORER PHOTOS RELEASED


     Four new images from NASA's Cosmic Background Explorer are 
available to media representatives through the Broadcast and 
Imaging Branch, 202/358-1741.  Today, these images are being 
presented at the 181st Meeting of the American Astronomical 
Society in Phoenix, Ariz.

     The images show the universe in the full range of infrared 
wavelengths.  They show infrared sources such as dust within 
Earth's solar system, stars in the Milky Way Galaxy, and dust and 
stars in other galaxies.  

     The pictures were created from the Diffuse Infrared 
Background Experiment onboard COBE, which is the first space 
instrument to make a comprehensive search for the ancient fossil 
known as cosmic infrared background radiation.  This radiation is 
the remnant from the formation of the earliest objects in the 
universe, created 10 to 20 billion years ago.

     COBE, launched Nov. 18, 1989, is managed by NASA's Goddard 
Space Flight Center, Greenbelt, Md., for the Office of Space 
Science and Applications, Washington, D.C.

NASA INVENTION YIELDS BETTER, FASTER STRESS MEASUREMENTS

     A NASA engineer has developed an idea that could revolutionize the way 
engineers measure strains and stresses on products as varied as cars, planes 
and nuclear reactors.

     Karl Anderson at NASA's Ames-Dryden Flight Research Facility, Edwards, 
Calif., has invented a method to prevent errors caused by temperature changes 
in the wires that connect instruments, called strain gages, to recording 
devices.  Anderson's method uses a circuit called a "constant current loop"
that produces more accurate data while using smaller and sometimes fewer wires. 

     "I had been aware of the problem since coming to NASA in 1964," said 
Anderson.  "About a year ago, I came up with a different point of view and was 
able to find a practical solution."

     Researchers use strain gages to do structural tests on new products.  The 
common testing method uses a wiring system called the "Wheatstone bridge" 
that has been employed for almost 150 years.  However, thermal changes in the 
wires can result in errors when specimen temperatures vary greatly.  

     Anderson's new constant current loop circuit suppresses unwanted effects 
from the lead wires and records only the correct strain and stress data.  It 
should produce great cost and time savings because engineers now can get 
valid measurements easily in situations where earlier tests had to be repeated 
and averaged to get accurate readings.

     "The constant current loop will tremendously benefit the measurement 
world that relies on electrical resistance to show what is going on," said 
Anderson.

     NASA has applied for patents on the innovation.  Anderson will present the 
new constant current method for strain gage signal conditioning and test 
results at a Western Regional Strain Gage Committee meeting in Pasadena, 
Calif., in February and at the International Instrumentation Symposium in 
Albuquerque, N.M., in May.

     NASA Technical Memorandum 104260, which details Anderson's research
results, is available from the National Technical Information Service, 5285
Port Royal Road, Springfield, Va. 22161.

RELEASE:  93-8

UNIVERSITIES FLY OZONE RESEARCH BALLOON FROM TEXAS TO FLA.

	A NASA-sponsored university group will launch a high-altitude research
balloon on Jan. 11, inaugurating a cooperative program to measure ozone
distribution and wind parameters in the Earth's stratosphere.

	Following launch from the South Shore Harbor Resort and Convention
Center, League City, Texas, at 8 a.m. EST, the 76-foot diameter, helium-filled
balloon will ascend to an altitude of 110,000 feet and fly across the Gulf of
Mexico to Florida.

	When the balloon reaches central Florida, a radio command will be sent
to parachute the gondola and its instrument package back to Earth for recovery
and reuse.

	Throughout the day-long flight, cooperating teams of amateur radio
operators in Texas, Louisiana, Mississippi, Alabama and Florida will receive
position reports, ozone data and video images from the balloon's 50-pound
gondola and will relay this information via high-frequency radio to a Utah
State University balloon chase van.

	The radio operators also will "home" on the payload's radio beacons to
assist in recovering the gondola and balloon.  In addition, the Federal
Aviation Administration will track a radar transponder in the gondola during
ascent and descent through controlled airspace.

	The instrument package was designed and built by a volunteer team of
space grant students and faculty from Utah State University's Space Dynamics
Laboratory and from the Bridgeland Amateur Radio Club in the Cacha Valley of
northern Utah.  This flight is the eleventh for this team and the first of 24-
hours' duration.

	Extended-duration flights will be launched from Canada, the United
States, Mexico and Central America to measure ndistribution and stratospheric
circulation on a long-term basis.

	The balloon is a revolutionary "superpressure" design manufactured by
Winzen International of San Antonio and Sulphur Springs, Texas.  It is
fabricated of Nylon film thinner than a human hair and is designed to stay
aloft continuously for a year or more.

	The balloon launch is sponsored by NASA's National Space Grant College
and Fellowship Program Office, Washington, D.C., and will take place during the
third annual meeting of all 50 state consortia.  The District of Columbia and
Puerto Rico also are participating in the program.

SPACE STATION FREEDOM PROPULSION FIRING TESTS UNDERWAY

	Static firing tests of a propulsion development test article for Space
Station Freedom began in late December at NASA's White Sands Test Facility
(WSTF) in New Mexico.

	The test series will validate the concept and preliminary design of the
propulsion module to be used for space station attitude control, orientation,
speed and altitude control and avoidance of space debris.

	"Freedom is no longer a 'paper-station'," commented Richard Kohrs,
Director of the Space Station Freedom Program in Washington, D.C..  "And the
beginning of critical tests with the propulsion module system at White Sands
represents the next and certainly not the last in a long string of reality
checks for Freedom focussing on launch of the first element in the assembly
sequence in about 3 years."

	"We have seen Space Station Freedom progress from concept to design
and now to validation of hardware," said Larry Morata, Vice President and
General Manager of McDonnell Douglas Aerospace (MDA) Space Station Division.
"We are on the way to constructing a facility that will promote science and
exploration for years to come."

	During Shuttle's second space station assembly flight, two propulsion
modules will be positioned on Freedom.  Two more will be added following
man-tended capability and an additional pair will be added prior to permanently
manned capability.

	Early propulsion modules will have 13 thrusters located at both ends
and on top of each module.  On later modules, the number of thrusters will be
scaled down to nine.  The thrusters can be fired independently, allowing
precise positioning of the station.

	The article being tested in New Mexico has 10 small thrusters, each
with an operational range of 9 to 25 pounds of thrust and three large thrusters
with 20 to 55 pounds of thrust.

	MDA Space Station Division, under contract to the NASA Johnson Space
Center (JSC), Houston, is responsible for the development and testing.
McDonnell Douglas previously carried out structural dynamics and vibration
testing at JSC.  The test series will continue at WSTF as needed to complete
validation of the design.

The spacecraft is in Array Normal Spin and continues to perform as
expected. Teams are continuing to study the Attitude Control Subsystem
miscompared star problem.

Downlink is via the HGA (High Gain Antenna) at 2 kilobits per second.
Uplink is at 125 bps using the LGA (Low Gain Antenna). HGA calibration
activities were completed last evening.  Those calibrations indicate
HGA performance to be nominal.

With completion of C5 B as scheduled at 7:00 PM last evening, no flight
sequences are currently active.  This is to provide a ten day window to
allow upload of a new Flight Software build.

Teams are preparing Flight Software Build 7.1.1 for uplink on January 13
though 15.  Build 7.1.1 contains changes to AACS (Attitude and Articulation
Control Subsystem) Fault Protection logic determined to be necessary by
the Spacecraft Team.  These changes are not related to the Celestial
Sensor Assembly miscompared star situation.

The next Flight Sequence, C6 B (necessary C6 A activities were moved
into C5 B) is scheduled to go active on January 18.

Ka Band Link Experiment (KaBLE) activities have begun and are scheduled
to take place daily through January 12.  There are additional KaBLE
opportunities projected for January 16 and 17.

                             January 6, 1993
                               1:00 PM PST

The spacecraft is in Array Normal Spin; the downlink data rate is at 250
bps while the uplink data rate is 125 bps utilizing the Low Gain Antenna.

A new Star Catalog/Ephemeris load was uplinked last evening and
verification of successful execution of the "Use" command received.

Teams are continuing to evaluate Attitude Control subsystem telemetry to
determine what is causing the misidentified star situation.  The Celestial
Sensor Assembly misidentified star counter continues to increment to an
average of 10 during each 100 minute ANS revolution of the spacecraft,
after which an expected star is detected and the counter reset to zero.
A correlation has been developed between the misidentified star count
increase and the time at which Mars comes into the CSA's field of view.
However, there has been no verification that this is the source of the
problem from the Tiger Team, which continues to review data and examine
all theories.

Mission Operations System teams feel that the spacecraft is performing
predictably and have procedures in place to respond to any further
occurrences of the problem prior to spacecraft loss of inertial reference.

Uplink of Flight Sequence C5 B which would affect transition to High Gain
Antenna operations is scheduled for this evening, with activation to occur
tomorrow morning.  HGA operations will significantly increase the
downlink data rate capability.  Upon successful transition to HGA
Operations is verified, the Ka Band Link Experiment (KaBLE) will begin.

     All spacecraft and science operations are performing well.
Ground controllers are carrying out routine data-gathering
activities and experiment reconfigurations as required.  The 34-
meter ground antennas are being used for ranging when the
spacecraft is sending data at a low bit rate.  Seventy-meter-
antenna ranging passes are also performed periodically.  

     Earth-pointing maneuvers were carried out on Dec. 27 and 30,
1992, and on Jan. 3, 1993.  The next maneuver is scheduled for
Jan. 7, 1993.

     Today Ulysses is about 688 million kilometers (428 million
miles) from Earth, traveling at a heliocentric velocity of about
32,000 kilometers per hour (21,000 miles per hour).  Ulysses is
about 15.5 degrees south of the ecliptic plane in which the
planets orbit, slowly looping its way back toward the sun.
