Mission Control Status #13
MISSION CONTROL CENTER
STS-55 Status Report #13
Friday, April 30, 1993, 5 p.m. CDT
Houston flight controllers had a quiet afternoon Friday as Columbia hummed
along with no new systems anomalies, and controllers at the German Operations
Control Center have kept busy as STS-55 science operations continue.
Mission Specialist Jerry Ross used the Holographic Optics Laboratory to study
Marangoni convection which causes fluid currents to move from low pressure
areas to high pressure areas. Investigators on the ground watched the
convection currents develop as particles in the HOLOP started oscillating.
Also today, Ross and Payload Specialist Ulrich Walter performed some
respiratory procedures for investigations studying gas exchange within the lung
in microgravity. There are four experiments studying this aspect of human
physiology.
Later today, Payload Specialist Hans Schlegel will be the first subject for a
U.S. investigation that calls for injecting saline into each of the payload
crew members. The experiment examines the natural fluid shifts that occur on
orbit and disrupts those shifts with the fluid infusion. The flight
experiment, like many of the life science investigations, will be supplemented
with data collected before and after the flight.
Pilot Tom Henricks, who has been off duty most of the day, will also conduct
some tests with the Crew Telesupport Experiment this evening.
German scientists are pleased with the science data that has been collected so
far in the mission. The 88 experiments are intended to study life sciences,
material sciences, technology applications, Earth Observations, astronomy and
atmospheric physics.

Mission Control Status Report #14
MISSION CONTROL CENTER
STS-55 Status Report #14
Saturday, May 1, 1993, 8:30 a.m. CDT
Columbia performed trouble-free during the night and Mission Control was
fairly quiet as the crew continued experiments in the German Spacelab --
including having the first space I.V. administered.
In the first run of an investigation hoped to provide insight into the effects
on various body systems of restoring the amount of body fluids lost in the
first days of space flight, Mission Specialist Bernard Harris, M.D., assisted
crewmate Hans Schlegel of the German Astronaut Corps to take an infusion of
about two liters of saline solution. The solution replaces body fluids that
are lost as astronauts adapt to weightlessness. Once the fluid is infused, the
echocardiograh is used to study the heart, kidney, aorta, and femoral arteries
responses to the replacement of the fluid. The fluid will be gone from the
body within 24 to 36 hours after infusion.
For the investigation, an electrocardiograph, blood samples and breathing
evaluations are performed both before and after the saline injection. Schlegel
is the first of four crew members that will have the saline injection and
undergo the tests. Harris is scheduled for an infusion later this morning.
Shuttle astronauts have had to drink large quantities of water prior to their
return home from a mission for several years as a method of replacing the lost
fluid and easing their return to gravity. The infusion experiments may help
validate whether bedrest studies done on Earth to mimic the weightless effects
are accurate as well.
Other than the infusion, Schlegel had a light work shift on the spacecraft
today as ground controllers provided him a mid-flight break from the hectic
Spacelab work. All crew members will be scheduled for similiar breaks. Along
with Harris and Schlegel, Mission Specialist Charlie Precourt watched over
Columbia during the night, maneuvering the spacecraft when needed to point
various cameras in the cargo bay at stars or the Earth.
The blue team was awakened at 4:30 a.m. CDT and relieved the red shift at
about 6:30 a.m. CDT. A United States press conference with reporters in
Houston and Florida is scheduled for the blue team at 2:05 p.m. CDT today.

STS-55 Status Report #15
MISSION CONTROL CENTER
Saturday, May 1, 1993, 10 a.m. CDT
Payload Specialist Ulrich Walter of the German Astronaut Corps was the second
test subject today in an experiment that researchers hope will provide insight
into the effects on various body systems of restoring body fluids lost in the
first days of space flight. About two liters of saline solution is infused
through a catheter in an arm vein. Jerry Ross assisted Walter with the
infusion procedure. Once the fluid is infused, the echocardiograh is used to
study the heart, kidney, aorta, and femoral arteries' responses to the
replacement of the fluid. The fluid will be gone from the body within 24 to 36
hours after infusion.
The whole protocol includes an electrocardiograph, blood samples and breathing
evaluations performed both before and after the saline injection. Mission
Specialist Bernard Harris, M.D., will be the third test subject for the
investigation. Jerry Ross has set up the equipment and installed the saline
bag in the warmer for Harris' test which is scheduled for the Red Team's
post-sleep period at 4:15 p.m. CDT today.
Just before 9 a.m. CDT, Capcom Carl Meade asked Ross and Walter to minimize
opening the door of the orbiter refrigerator/freezer after data indications
that the OR/F compressor was running longer than usual causing the compressor
temperature to rise. With the saline infusion protocols being conducted this
morning, numerous blood, urine and saliva samples have been collected. The
warm samples also contribute to the compressor running longer. Although the
temperature was within normal limits, engineers are being conservative with the
OR/F operations since the other unit is not working.
After the Blue Team's lunch break today, Ross has a light work shift for the
remainder of his work day. Ground controllers scheduled staggered mid-flight
breaks from the hectic Spacelab work pace for each payload crew member. A
United States press conference with reporters in Houston and Florida is
scheduled for the blue team at 2:05 p.m. CDT today.

Status Report #16
MISSION CONTROL CENTER
Saturday, May 1, 1993, 5 p.m. CDT
STS-55 Pilot Tom Henricks sent a message from Columbia to Earth using the Crew
Telesupport Experiment today as the crew and ground controllers in Germany put
the interactive graphics device through its paces.
Henricks worked with ground controllers for more than an hour to establish a
link from Columbia to the Payload Operations Control Center. Once Columbia's
system could communicate with the ground system, an "Etch-a-sketch" type
message was sent down. Investigators were not able to establish a similar link
from the ground to Columbia.
Payload crew members are preparing for Mission Specialist Bernard Harris'
saline infusion. The procedure, which has been performed already on Payload
Specialists Hans Schlegel and Ulrich Walter, is part of an investigation of the
cardiovascular system's adaptation and function in microgravity. Roughly two
liters of saline are injected into each subject after which a variety of
physiological parameters are measured.
Also today, Mission Specialist Ulrich Walter checked the fish and frog larvae
experiments and reported that several of the animals had died. There are many
specimens onboard and investigators do not believe the losses will affect the
science.
Saturday was a quiet day for the flight control team as Columbia continued to
operate without any new anomalies.
