MISSION CONTROL STATUS REPORT

MISSION CONTROL CENTER
Status Report #19

Sunday, May 2, 1993, 5 p.m. CDT

Ground controllers in Houston and Germany are beginning to develop plans for a
10th day in space following mission managers' decision to extend STS-55 one
day.

Crew members have been taking measures for the last several days to save enough
energy for an extra day on orbit.  Their efforts were rewarded this morning
when managers announced that Columbia's 14th flight would end Thursday, May 6,
with landing at the Kennedy Space Center. Pre-flight planning included
discussions about activities on an extra day, but details of the 10th day will
be developed over the next few days.

This afternoon, Pilot Tom Henricks performed a variety of orbiter tasks such as
stowage of the Crew Telesupport Experiment and a waste water dump.  Mission
Specialist Jerry Ross, however, was busy with materials science and biology
experiments.  Earlier today, Ross was the final subject in the saline infusion
experiment that designed the study the cardiovascular system in orbit.

Ross also provided additional information about the contents of the orbiter
refrigerator/freezer.  Following those discussions, ground controllers in
Germany and Houston believe the unit has plenty of space for the required urine
and blood samples.

Following a handover from the "day shift" -- Commander Steve Nagel, Henricks,
Ross and Walter, the "night shift" -- Mission Specialists Charlie Precourt and
Bernard Harris and Payload Specialist Hans Schlegel -- will begin another busy
day of payload activities.  All seven crew members will participate in a
conversation with German Federal Minister of Research and Technology Matthias
Wissman at 5:20 a.m.  CDT, followed by a press conference.

Columbia continues to work with no new systems anomalies in a 162 by 156 orbit.

MCC Status Report #20

MISSION CONTROL CENTER
STS-55 Status Report #20

Monday, May 3, 1993, 6 a.m. CDT

Columbia's crew remained on schedule as they worked through various
experiments in the German Spacelab and tended to several housekeeping chores.

German Space Agency Payload Specialist Hans Schlegel manipulated the Rotex
robotic arm from onboard Columbia, using a hand controller and wearing special
goggles that provided three-dimensional views from TV cameras mounted on the
robot's gripping mechanism.  Schlegel gave ground controllers at the German
Space Operations Control Center an overview of the robot controls onboard as he
evaluated them.

In addition, Schlegel, along with fellow lab crewman Bernard Harris, closely
watched the meals they ate and later took a trace substance as part of an
experiment that tracks the amount of nitrogen in the body in weightlessness.
Work with melting metals and studying plant cells also continued in experiments
onboard, as did studies of the behaviour of fluids in weightlessness.

The crew also organized the blood and urine samples in the freezer aboard the
spacecraft to move the empty racks in the freezer to the front and assist in
keeping down the amount of time required to store new samples inside.  The
samples in the freezer were disorganized because the crew has been keeping the
door open for very short periods of time as samples are stored, thus most
samples were in front and most empty spaces in the back of the unit.

The contingency waste bag that wastewater is flowing into aboard Columbia also
was moved to a wet trash compartment under the middeck floor that provides good
ventilation to reduce any odors from the bag.

STS-55 Status Report #21

Monday, May 3, 1993, 10:30 a.m.  CDT

The STS-55 crew held an on-orbit press conference with German news media at
5:20 CDT this morning.

The Blue Team of Steve Nagel, Tom Henricks, Jerry Ross and Ulrich Walter took
over Spacelab experiment work and Orbiter operations at 6 a.m.  CDT.

Walter, along with Harris and Schlegel of the Red Team, are test subjects this
morning for a study of the whole-body nitrogen turnover.  Investigators want to
further understand the interaction beween the observed loss of nitrogen and
muscle function and size under micro gravity conditions.  In preparation for
the study, the astronauts monitored their diets before the Shuttle mission so
that investigators could determine each one's 24-hour energy requirements and
dietary composition.  For the test, the astronauts ingest a special tracer
amino acid that will show up in the blood and urine samples collected over a
12-hour period during which they eat special meals that provide specified
amounts of nutrients.

Other experiments underway this morning include measurements of the body's
blood pressure regulating system, and a cell polarity and gravity study.
Garden cress roots are being studied to determine how much the absence of
gravity affects cellular development in the roots.

Columbia is performing well.  Power management measures are being followed to
maintain cryogenic fuel margins for the extra day of science operations added
to the flight.

Houstonians will be able to see Columbia pass overhead on Tuesday morning at
5:58 a.m.  CDT. Columbia can be seen for about two minutes 15 degrees above
west-southwest traveling to 57 degrees above south-southeast.

MARS OBSERVER MISSION STATUS
April 30, 1993

The Mars Observer spacecraft switched to an automatic fault protection mode,
called "contingency mode," at approximately 1:30 a.m.  Pacific Daylight Time on
Thursday, April 29.  Ground- controllers at JPL discovered the situation at 6
a.m.  PDT, when the Madrid Deep Space Network facility did not receive the
expected spacecraft signal at the scheduled acquisition time.  All telemetry
indications were normal at conclusion of the preceding pass at Goldstone. At
reacquisition, indications were that the spacecraft was no longer in normal
inertial reference mode.

Contingency mode is designed to restore communications when the spacecraft
loses attitude reference and cannot point the high-gain antenna at Earth. The
reconfiguration automatically switches spacecraft communications from the
high-gain to the low-gain antenna.  Data rates are reduced and the solar arrays
are repositioned to a more favorable orientation toward the sun.  Preliminary
indications suggest that the spacecraft lost inertial reference to the sun,
which triggered the fault protection mode.

The incident, which last occurred on April 9, 1993, is understood and not
considered serious.  No hardware problems were involved and the spacecraft
performed perfectly in switching to contingency mode.  The Mars Observer flight
team planned to return the spacecraft to normal cruise mode today.

Today the Mars Observer spacecraft is about 22 million kilometers (13.5 million
miles) from Mars and 204 million kilometers (127 million miles) from Earth. The
spacecraft is traveling at a velocity of about 7,200 kilometers per hour (5,000
miles per hour) with respect to Mars.
