Following Space Shuttle Columbia's successful launch, NASA Administrator Daniel
S. Goldin stressed NASA commitment to safety and mission success.
Administrator Goldin also commended and thanked our German partners for their
patience and commitment to the success of this scientific endeavor. Space
Shuttle Columbia's STS-55 mission is primarily devoted to Germany for
conducting a wide range of experiments in the microgravity environment of space
flight.

STS-55 Status Report #2
MISSION CONTROL CENTER
Tuesday, April 27, 1993, 6:30 a.m. CDT
Crewmembers aboard Columbia spent the night powering up new experiments in the
German Spacelab and continuing work with experiments that have been ongoing
since yesterday afternoon.
Columbia and all of the Spacelab equipment powered up so far are in excellent
shape. Among the experiments performed during the night was the fusion of
plant cell protoplasts, a process of electrically fusing plant cells, in most
instances from tobacco plants selected because of their cellular qualities, to
create hybrid cells.
During the night, the materials processing lab rack, called MEDEA, also was
powered up. The materials experments will focus on growing and working with
substances such as gallium arsenide crystals, used in microcomputer chips and
other electronic circuitry.
In addition, a stereo camera called MOMS mounted at the back of the lab's
exterior has been viewing various areas of Earth as Columbia orbits, taking
images that may allow maps of the terrain to be made with a resolution of
objects as small as a few yards across. Another lab area powered up is the
Anthorack, an area that will focus on medical investigations of the effects of
weightlessness on humans.
A survey of Columbia's cargo bay with television cameras showed a loose thermal
blanket on the airlock hatch. The loose insulation blanket poses no problems
for the shuttle. A similar situation occurred on mission STS-40, and
controllers may have to take a little extra care to ensure the hatch doesn't
become too hot or too cold.
Columbia fired its steering jets in a brief adjustment early yesterday evening
designed to optimize the shuttle's orbit. The small firing had the net effect
of dropping the shuttle's orbital high point by 2 nautical miles. Columbia is
now in a 161 nautical mile circular orbit, completing one orbit every 90
minutes.

STS-55 Status Report #3
MISSION CONTROL CENTER
Tuesday, April 27, 1993, 9:30 a.m. CDT
The Blue Team of Steve Nagel, Tom Henricks, Jerry Ross, and Ulrich Walter took
over the Orbiter operations and science laboratory work at about 7:30 a.m.
Overnight, the Red Team of Charlie Precourt, Bernard Harris and Hans Schlegel
continued experiment work with the fusion of plant cell protoplasts, a process
of electrically fusing plant cells from tobacco plants. German scientists have
reported the first series of cell eletrofusion attempts were successful.
Results of this experiment may lead to new plant hybridizing procedures.
The first respiratory monitoring measurements were taken this morning on
Payload Specialist Ulrich Walter for the series of lung function studies
included in the Anthrorack experiments. A series of measurements is planned
throughout the flight. The complement of Anthrorack investigations is
coordinated to gather more information on the interdependent human biological
systems and how they affect each other in the microgravity environment.
The Flight Control team is consulting with engineers on the orbiter
refrigerator/freezer. The primary OR/F was not cooling properly on flight day
one and was replaced with the backup unit. Although the backup OR/F is
functioning well, mission managers and scientists strongly prefer having a
backup refrigerator/freezer ready to go on line should the other unit have
difficulties. The stable preservation of biological samples is necessary for
the post-flight studies that will complete the human physiology experiments.
Columbia continues to perform well on its fourteenth mission. Flight planners
expect to know by week's end if an extra day of science work will be available
should electricity-producing fuel margins be adequate.

STS-55 Status Report #4
Tuesday, April 26, 1993, 5 p.m. CDT
Columbia passed a major milestone this afternoon as the shuttle fleet's
oldest orbiter, marking the 100th day of flight time in space.
Shortly after Columbia crossed the milestone at 1/06:18:34 Mission Elapsed
Time, STS-55 Commander Steve Nagel congratulated the teams that built and
maintain the orbiter.
"We've really got this laboratory cranked up," Mission Specialist Jerry Ross
told controllers at the German control center this afternoon.
Both Ross and Payload Specialist Ulrich Walter performed exercises that
measured and analyzed their exhaled gases. The procedures are part of an
investigation of lung function for the suite of Anthrorack experiments. Then,
both astronauts worked with experiments to study the crystallization of
different semi-conductor materials and the solidification of metallic
alloys.Pilot Tom Henricks also performed the first experiments to test the
reflexes that maintain blood pressure.
The afternoon also went smoothly for flight controllers in Houston. The flight
control team located a small nitrogen leak into the crew cabin, but a
troubleshooting procedure performed by crew members quickly isolated the leak
in the of the common manifold area. The isolated leak will have no impact on
the operations of the orbiter's water tanks, but may affect the use of the
urine monitoring system.
During STS-55, the urine monitoring system is being used to collect samples for
the life sciences experiments and for a comparison test called Detailed
Supplementary Objective 323. Because of the nitrogen leak isolation,
pressurized water will not be available for the UMS to completely clean itself
in between sample collections.The DSO 323 investigators have decided to
continue use of the UMS and payload operators in Germany are currently
discussing whether to switch to an alternate collection method or to continue
UMS operations knowing there may be some minor contamination between samples.
Columbia is currently in a 161 by 160 n.m. orbit.
