5/11/93: NASA AND NATIONAL INDUSTRY RESEARCH GROUP SIGN AGREEMENT
Charles Redmond
Headquarters, Washington, D.C. May 11, 1993
Cheryl Eberwein
National Center for Manufacturing Sciences, Ann Arbor, Mich.
RELEASE: 93-82
NASA and the National Center for Manufacturing Sciences (NCMS) have
signed an agreement which will allow the two organizations to propose joint
research projects.
The national center is a non-profit research consortium created by U.S.
industries to conduct, sponsor, fund and otherwise promote scientific
research, development and demonstrations of technologies or scientific
applications which will improve manufacturing processes and materials in the
United States and Canada.
NASA Administrator Daniel Goldin said "One of NASA's responsibilities
is to help transfer our skills and knowledge to the industrial base of this
nation. This agreement will help us carry out that responsibility." Goldin
added that NASA has much to learn from the NCMS member industries and
looked forward to research projects which would use NASA's aeronautical and
space science test facilities in joint projects with industry.
Under terms of the agreement, NASA divisions or centers can propose
joint research projects with individual member industries of the NCMS. The
industries are equally free to propose joint research projects with elements of
NASA. The collaborative activities also can include joint workshops covering
any manufacturing process or material or research facility.
These separate research projects would be subject to separate
agreements in two categories: reimbursable and non-reimbursable. The
reimbursable activities include those uses of NASA facilities such as wind
tunnels or vacuum chambers for research projects which NASA has a minimal
collaborative interest. The non-reimbursable activities would include
collaborative projects using NASA or NCMS industry facilities or equipment
for which both parties have a strong interest.
The overall agreement maintains a NASA program priority for use of
facilities which might be covered in separate joint research agreements. The
agreement also calls for shared distribution of profits produced by NCMS
member industries achieved through collaboration with NASA.
Conversely, the agreement allows NCMS members which shared in
collaborative research projects to have reasonable access for reasonable
periods of time to NASA patents which resulted from that research.
Because the overall agreement allows for patentable research, the
agreement is heavily oriented toward the protection of both NASA and NCMS
member industry's intellectual and patent rights.

% Mars Observer switches to
contingency mode;
% Skylab, Spacelab, Space Station
conference;
% Improvements to the world's
largest wind tunnel planned.
Once again, the Mars Observer went into
contingency mode, the self-protective default
mode, about 7:57 a.m. EDT, Sunday, May 9,
1993.
The sun sensor on the spacecraft indicated
that the position of the sun was not in the
same location as its on-board flight software
expected it to be. This caused the
contingency mode to occur. Communication
automatically switches to the low-gain
antenna and all unnecessary power loads turn
off.
Flight controllers at NASA's Jet Propulsion
Laboratory have decided to evaluate some
software modifications that will improve the
spacecraft's attitude control performance
before returning the Mars Observer to the
normal outer cruise mode.

On May 13, in Huntsville, Ala., the
International Conference on Skylab, Spacelab,
Space Station, and Beyond will be held. The
all day event will mark the 20th anniversary
of the launch of Skylab, the world's first space
station. The Conference will also
commemorate the 10th anniversary of the
first mission of Spacelab, a research
laboratory carried of the Space Shuttle; and
the 10th anniversary of Space Station
concepts development.
Astronauts, scientists, engineers and
managers from around the world will discuss
the gained knowledge and expertise provided
by these programs of space exploration.
Exhibits of space hardware and other
memorabilia from the Skylab, Spacelab, and
the Space Station development will be on

Thanks to a $25 million NASA sound
insulation project, the world's largest wind
tunnel will soon become the world's quietest.
NASA plans to design and install an acoustic
lining in the 40-by-80 foot test section of the
National Full-scale Aerodynamics Complex at
the Ames Research Center.
The improved wind tunnel will help U.S.
industry to develop quieter engines for a
future high-speed civil transport and for new,
advanced helicopters. The project design will
take the next 2 years to complete. The
construction on the wind tunnel is scheduled
to begin in the spring of 1995.

GALILEO
MISSION DIRECTOR STATUS REPORT
POST-LAUNCH
April 23 - 29, 1993
SPACECRAFT
1. On April 22 and 23, delta Differenced One-way Range (DOR) passes were
performed over DSS-14/63 (Goldstone/Madrd 70 meter antennas) and DSS-14/43
(Goldstone/Canberra 70 meter antennas), respectively. Initial results \
indicate the delta DOR pass on April 22 was unsuccessful due to ground
station hardware problems but the one on April 23 was successfully performed.
2. On April 23, a cruise science Memory Readout (MRO) was performed for the
Magnetometer (MAG) instrument. Analysis indicates the data was received
properly.
3. On April 23, the spare power relay contacts were commanded closed via the
spacecraft stored sequence. These relays were commanded closed by the CDS
(Command Data Subsystem) prior to launch and were again commanded closed to
preclude the possibility at Jupiter of the PPS relays/wiring being a
source of internal electrostatic charge (IESD).
4. On April 26, cruise science Memory Readouts (MRO) were performed for the
Extreme Ultraviolet Spectrometer (EUV), Dust Detector (DDS), and Magnetometer
(MAG) instruments. Preliminary analysis indicates the data was received
properly.
5. During the period from April 26 to April 27, a navigation cycle was
performed. This navigation cycle provided near-continuous acquisition of
two-way doppler and ranging data during three consecutive passes of the
spacecraft over DSS-63, DSS-14, and DSS-43.
6. On April 26, real-time commands were sent to test slew the Radio Relay
Antenna (RRA) in preparation for the mini-sequence slew test on April 28.
The RRA was slewed from approximately 3.5 degrees from stow to approximately
20.3 degrees. Preliminary analysis indicated the antenna slewed to about 18
degrees which was well within the predicted range. The RRA was commanded back
to approximately 15.2 degrees from stow. Preliminary analysis indicated the
antenna reached about 15.8 degrees also well within the predicted range. The
RRA motor temperature was at 1 degree C at the start of the activity and had
increased to 1.6 degrees C at its completion.
After verifying proper RRA slewing, the RRA slew test mini-sequence was
uplinked to the spacecraft for execution on April 28. Upon successful uplink,
a Delayed Action Command (DAC) was sent which will reposition the stator on
May 4 to its initial pre-test position. Also, a DAC was sent to turn the
Two-Way Noncoherent (TWNC) on April 28 prior to the start of the RRA slew test
mini-sequence.
7. On April 27, a NO-OP command was sent to reset the command loss timer to
264 hours, its planned value during this mission phase.
8. On April 28, the RRA slew test executed nominally. The spacecraft under
stored sequence control performed six RRA slews starting at about 16 degrees
from stow and going to 53 degrees, back to 25 degrees, then to 51 degrees,
back to 22 degrees, then to 48 degrees and then back to 21 degrees. All of
the slews were well within the predicted range. The RRA motor temperature was
at 2.3 degrees C at the start of the activity and had increased to 4.4
degrees C at its completion. After completion of the RRA slews, real-time
commands were sent to reconfigure back to the pre-test configuration.
9. The AC/DC bus imbalance measurements have not exhibited significant change
(greater than 25 DN) throughout this period. The AC measurement reads 17 DN
(3.9 volts). The DC measurement reads 134 DN (15.7 volts). These
measurements are consistent with the model developed by the AC/DC special
anomaly team.
10. The Spacecraft status as of April 29, 1993, is as follows:
a) System Power Margin - 75 watts
b) Spin Configuration - Dual-Spin
c) Spin Rate/Sensor - 3.15rpm/Star Scanner
d) Spacecraft Attitude is approximately 23 degrees
off-sun (lagging) and 4 degrees off-earth (leading)
e) Downlink telemetry rate/antenna- 40bps(coded)/LGA-1
f) General Thermal Control - all temperatures within
acceptable range
g) RPM Tank Pressures - all within acceptable range
h) Orbiter Science- Instruments powered on are the PWS,
EUV, UVS, EPD, MAG, HIC, and DDS
i) Probe/RRH - powered off, temperatures within
acceptable range
j) CMD Loss Timer Setting - 264 hours
Time To Initiation - 203 hours
GDS (Ground Data Systems):
1. The first Galileo-GDS test of the MGDS V18.0 Command System (CMD) took
place April 27, 1993 with DSS-61 (Madrid 34 meter antenna). The test went
well and demonstrated that the new command system interfaced with the new DSN
(Deep Space Network) Group 5 Command Processor Assembly (CPA). The test was
successful and the next test for V18.0 CMD is scheduled for May 1, 1993 with
DSS-15 (Goldstone 34 meter antenna).
2. The April System Engineers Monthly Report(SEMR)/Ground System Development
Office (GSDO) MMR was conducted Thursday, April 29. A review of current
Project and Institutional (DSN and MOSO) system status was conducted. On-going
cruise development plus the GSDO Phase 1 and 2 delivery schedules, past months
accomplishments and potential problem areas were discussed. No significant
schedule changes or significant problems were reported.
TRAJECTORY
As of noon Thursday, April 29, 1993, the Galileo Spacecraft trajectory
status was as follows:
Distance from Earth 187,745,300 km (1.26 AU)
Distance from Sun 296,335,800 km (1.98 AU)
Heliocentric Speed 89,100 km per hour
Distance from Jupiter 522,015,800 km
Round Trip Light Time 20 minutes, 58 seconds
SPECIAL TOPIC
1. As of April 29, 1993, a total of 70259 real-time commands have been
transmitted to Galileo since Launch. Of these, 65150 were initiated in the
sequence design process and 5109 initiated in the real-time command process.
In the past week, 74 real time commands were transmitted: 73 were initiated
in the sequence design process and one initiated in the real time command
process. Major command activities included commands to perform the initial
RRA slew test, uplink the RRA slew test mini-sequence, DACs to reposition the
stator and turn the TWNC on, reset the command loss timer, and execute the
RRA slew test.

MARS OBSERVER MISSION STATUS
May 3, 1993
The Mars Observer spacecraft was returned to normal cruise mode at 3:15 p.m.
Friday, April 30, 1993, after spending about 38 hours in a fault protection
mode known as "contingency mode." In contingency mode, the spacecraft
automatically switches from the high-gain to the low-gain antenna and
repositions itself to a more favorable orientation toward the sun.
No hardware problems were involved in the incident and the spacecraft performed
perfectly in switching to contingency mode. JPL's flight engineering team will
continue to study the problem until an adequate software fix can be designed
and uplinked.
Today Mars Observer is about 21 million kilometers (13 million miles) from Mars
and about 209 million kilometers (130 million miles) from Earth. The spacecraft
is traveling at a velocity of about 7,200 kilometers per hour (4,500 miles per
hour) with respect to Mars.

MARS OBSERVER MISSION STATUS
May 10, 1993
The Mars Observer spacecraft again switched into contingency
mode -- a self-protective default mode -- at about 4:57 a.m.
Pacific Daylight Time on Sunday, May 9, 1993. Flight controllers
at JPL have decided to evaluate some software modifications that
will improve the spacecraft's attitude control performance before
returning to the normal outer cruise mode.
Contingency mode occurs when the spacecraft is unable to
correctly identify its position in space with respect to certain
stars and the sun. Specifically, the spacecraft's sun sensor
indicates that the position of the sun is not in the same
location as its on-board flight software expects it to be. When
that happens, the spacecraft thinks it has lost its attitude
reference and automatically points at the sun, throwing the high-
gain antenna off target with Earth. Communications are
automatically switched from the high-gain to the low-gain
antenna. All unnecessary power loads, such as the science
instruments and tape recorders, are turned off.
A software fix that will redefine some attitude control
parameters is being evaluated by JPL systems engineers. That
software was expected to be ready for uplink in the next several
weeks.
Today Mars Observer is about 20 million kilometers (12.5
million miles) from Mars and 220 million kilometers (136 million
miles) from Earth. The spacecraft is traveling at a velocity of
about 7,000 kilometers per hour (4,000 miles per hour) with
respect to Mars.
