5/04/93: ASTRONAUT SEDDON INJURED DURING TRAINING
Barbara Schwartz May 4, 1993
RELEASE NO. 93-032
Dr. M. Rhea Seddon, payload commander on Spacelab Life Sciences- 2
mission scheduled for launch this fall, broke four metatarsal bones in her left
foot during a routine training exercise at Johnson Space Center's orbiter
training facility May 3.
The STS-58 crew was practicing emergency egress from the orbiter, using
an inflatable slide similar to those used by the airline industry for landing
emergencies to evacuate passengers. As Dr. Seddon was sliding down the slide,
her left foot became pinned under her, causing four minor bones to break.
"There will be no impact to the mission because of Dr. Seddon's injury.
She may miss a small amount of training in the next two weeks, but she is an
experienced astronaut and most of these early training activities are refresher
courses. She will return to full-time training in two to four weeks," Flight
Crew Operations Director David C. Leestma said.
A safety review team lead by Gary Jackson of JSC's Safety Division has
been established as a precautionary measure to investigate the incident.

% STS-55 mission status;
% Mars Observer update;
% Launch preparation for Endeavour continue.
Columbia's crew continues on schedule to perform a busy curriculum of human
life science's experiments. For about an hour, communications were lost with
Space Shuttle Columbia after an errant command was sent to the spacecraft by
controllers. Flight controllers had to wait for the crew to recognize the lack
of communications and perform a procedure to restore them. At present all
communications, both on the spacecraft and on the ground, are functioning
normally.
Over the weekend, Columbia's crew members continued experiments in the German
Spacelab. Crew members administered the first I.V. in space on Saturday as
well.
On Sunday, mission managers decided to extend the STS-55 mission an extra day
to gather additional Spacelab science data. The opportunity came as a result
of the crew's ability to conserve enough electrical power. By continuing the
power saving efforts, flight controllers expect to accumulate up to 30 extra
hours of electrical generation capacity.
Columbia's extended mission will conclude with a landing at the Kennedy Space
Center on Thursday, May 6, 9:03 a.m. EDT.

The Mars Observer spacecraft returned to normal cruise Friday after spending
about 38 hours in a fault protection mode known as a "contingency mode." In
this 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.
The incident did not cause any hardware problems. However, flight engineers at
NASA's Jet Propulsion Laboratory will continue to study the problem until an
adequate software fix can be designed and uplinked.

Technicians at the Kennedy Space Center continue to prepare the Space Shuttle
Endeavour for its upcoming STS-57 mission. The targeted launch date is June 3,
1993. The STS-57 mission is scheduled to last 7 days, 23 hours.
Workers are planning to remove the fuel turbo pump from main engine #1 and make
preparations to load the pre-launch onboard propellants. Workers installed the
SHOOT payload aboard Endeavour and removed the heat shields from around the
main engine.

5/4/93: Planetary Mission Status April 1993
PLANETARY MISSION STATUS
April 27, 1993
VOYAGER 1 and 2: The two Voyager spacecraft continue their
interstellar mission with fields-and-particles data acquisition.
Voyager 1, launched September 5, 1977, is currently 7.8 billion
kilometers (4.8 billion miles) from the Sun, receding at 17.6 km
per second, after flying by Jupiter and Saturn in 1979 and 1980;
Voyager 2, launched August 20, 1977, to fly by Jupiter (1979),
Saturn (1981), Uranus (1986), and Neptune (1989), is now 5.97
billion kilometers (3.7 billion miles) from the Sun.
MAGELLAN: The Magellan spacecraft is continuing its survey of the
gravitational field of Venus, utilizing precise navigation of the
spacecraft in the near-Venus portion of its elliptical orbit,
through May 15, 1993. The Project plans to begin maneuvers to
circularize the orbit on May 25. Magellan was launched May 4,
1989, aboard Space Shuttle Atlantis with an IUS injection stage;
it radar-mapped more than 98% of Venus's surface from September
1990 to September 1992.
GALILEO: The spacecraft is now en route to Jupiter, scheduled to
go into orbit there on December 7, 1995. Spacecraft performance
and condition are excellent except that the high-gain antenna is
only partly deployed; science and engineering data are being
transmitted via the low-gain antenna. The Project is now
planning to use the low-gain antenna for the Jupiter mission and
the August 1993 encounter with asteroid Ida. Galileo was
launched October 18, 1989, by Space Shuttle Atlantis and an IUS,
and flew by Venus in 1990 and Earth in 1990 and 1992 for earlier
gravity assists and asteroid Gaspra in October 1991 for
scientific observation.
ULYSSES: The spacecraft is in a highly inclined solar orbit, now
almost 30 degrees south (relative to the Sun's equator), in
transit from its Jupiter gravity assist in February 1992 toward
its solar polar passages (about 80 degrees south and north) in
1994 and 1995. Ulysses spacecraft condition and performance are
excellent, and cruise science data-gathering continues. The
Ulysses spacecraft was built by the European Space Agency and
launched October 6, 1990 aboard Space Shuttle Discovery, with IUS
and PAM-S stages.
TOPEX/Poseidon: The satellite is healthy, and all scientific
instruments are performing normally, typically providing three
playbacks per day. The mission is to map ocean circulation.
TOPEX/Poseidon was launched August 10, 1992, aboard Ariane 52.
MARS OBSERVER: Spacecraft health and performance are normal, and
Mars Observer is on its planned trajectory leading to Mars orbit
insertion August 24, 1993, with the mapping orbit attained
November 8 and science operations planned to start November 22.
The Joint Gravitational Wave Experiment, in which Mars Observer
was joined by Ulysses and Galileo, completed data-gathering April
12, and data analysis has begun. Mars Observer was launched
aboard a Titan III/TOS vehicle on September 25, 1992.

STS-55 Status Report #22
Monday, May 3, 1993, 5 p.m. CDT
Pilot Tom Henricks and Houston ground controllers successfully transferred
graphic images this afternoon to and from Columbia with the Crew Telesupport
Experiment for the first time.
In a test with the interactive graphics system, technicians in Houston
successfully sent three messages to the orbiter. Henricks responded with two
messages. The activity was the first two-way transmission with the experiment.
Previous transmissions resulted only in a single image successfully transmitted
from Columbia.
Also today, end-of-mission plans are firming up as controllers in Houston and
Germany prepare for an extra day of science this week.
The additional time will help investigators replace lost data and improve
degraded data as well as provide additional information. Houston flight
controllers, in the meantime, have been identifying activities for the orbiter
crew and discussing the deorbit and landing options.
With the Kennedy Space Center as the prime landing site, equipment to gather
post-flight medical information has been shipped to Florida. Because of the
decreased ability to collect such information if landing were to occur at the
Edwards Air Force Base, mission managers are working to optimize the landing
opportunities to KSC.
Also this afternoon, payload activities kept Mission Specialist Jerry Ross and
Payload Specialist Ulrich Walter busy. Ross worked with materials science
experiments to develop crystals from semiconductor material and Walter
performed experiments studying the effects of polarization of cress plants in
microgravity. Both payload crew members participated in an investigation which
required that the astronauts ingest a special tracer amino acid that shows up
in the blood and urine samples. The study is focusing on the interaction
between the observed loss of nitrogen and muscle function and size under
microgravity conditions.
Columbia continues to operate without new systems anomalies as it circles the
Earth in a 162 by 157 n.m. orbit.

STS-55 Status Report #23
Tuesday, May 4, 1993, 2:30 a.m. CDT
Columbia's crew continued on schedule through a busy slate of human life
sciences experiments in the German Spacelab during the night, including an
investigation of lung function in weightlessness and the body's reactions to
glucose in weightlessness.
Mission Specialist Bernard Harris and German Space Agency astronaut Hans
Schlegel started out their 12-hour workshift without breakfast to perform a
glucose experiment that studies how much insulin an astronaut's body produces.
The two took a dose of glucose and then had three blood samples each taken over
the next hour and a half. They then had a late breakfast.
Next, Schlegel and Harris performed a series of breathing evaluations designed
to study the function of the lungs in space. Breathing measurements of both
crewmen were made first at rest and then while exercising on a stationary
bicycle.
Mission Control lost communications with Columbia for about an hour and 20
minutes after an errant command was sent to the spacecraft by controllers. The
command caused the shuttle's Ku-band dish antenna to lose track of the
communications satellite as the antenna was being switched from pointing to a
satellite over the Pacific Ocean to point at a satellite over the Atlantic.
Once communications were lost, flight controllers had to stand by for the crew
to recognize the lack of communications and then perform a procedure to restore
them. All communications equipment on the spacecraft and on the ground is
functioning normally.
Columbia is in a 162 by 156 nautical mile orbit, circling Earth every 90
minutes, 34 seconds.

The Blue Team took over the Spacelab science experiments at 7:30 central time
this morning. Red Team Mission Specialist Bernard Harris participated in a
television interview as part of a medical conference at the Mayo Clinic at 7:40
a.m. CDT.
Payload Commander Jerry Ross and German Space Agency astronaut Ulrich Walter
started out their 12-hour workshift without breakfast to perform a glucose
experiment that studies how much insulin an astronaut's body produces. The two
took a dose of glucose and then had three blood samples each taken over the

Next, Ross and Walter will perform a series of breathing evaluations designed
to study the function of the lungs in space. Breathing measurements of both
crewmen will be made first at rest and then while exercising on a stationary
bicycle.
Nagel and Henricks both exercised on the bicycle ergometer earlier this
morning. In between maneuvering Columbia to the various attitudes for the MOMS
camera observations, the inertial measurement alignments and the supply water
dump, Nagel and Henricks assisted the payload crew with experiment setups and
stowage.
Ross and Walter have stepped through several tasks on the experiments on the
behavior of various dissolved solutions in microgravity as well as checks of
plants and fungi growth studies.
At 10:03 a.m. CDT Tom Henricks reported the screen of CRT 4 went blank.
Henricks cycled the power switch to the CRT, but the screen stayed blank. Data
processing system engineers are evaluating the malfunction and may consider
sending commands to reload the computer's software.
Columbia's and the Spacelab's systems are operating well.

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.
