MCC Status #11
MISSION CONTROL STATUS REPORT
STS-57 Status Report #11
Saturday, June 26, 1993, 5 a.m. CDT
With a primary objective of their flight -- the retrieval of the EURECA
satellite -- completed, Endeavour's crew will turn its attention back to the
host of experiments aboard the shuttle and in the Spacehab module.
The crew was awakened at 1:07 a.m. after eight and a half hours of sleep for
the sixth day of the flight to the song "Holiday" performed by Madonna, played
to suggest the crew take some time to celebrate the success of their mission.
Activities today for the crew will include work with crystal growth, spacecraft
technology and biological experiments in the Spacehab. Among the experiments
will be an evaluation of maintenance equipment, including an oscilloscope and
electrical test meter, that may be used on Space Station Freedom.
In addition, the crew will run an experiment in transferring fluids in
weightlessness without creating bubbles in the fluid. The experiment, called
the Fluid Aquisition and Resupply Experiment, or FARE, studies filters and
processes that may lead to methods of refueling spacecraft in orbit and
transfers water between two foot-diameter transparent tanks on Endeavour's
middeck. During some tranfers, Endeavour's steering jets will be fired to
observe the disturbance created by them to the process.
As an evaluation of one activity that may be required for a shuttle to spend
long periods docked at the space station, Pilot Brian Duffy will turn off one
of Endeavour's three electricity-generating fuel cells today. The fuel cell
will be restarted in two days.
At about 12:22 p.m. central today, Commander Ron Grabe and Payload Commander
David Low will be interviewed by the Cable News Network about their flight.
Endeavour is in a 256 by 209 nautical mile orbit, circling Earth each 93
minutes.

MISSION CONTROL STATUS REPORT
MISSION CONTROL STATUS REPORT
STS-57 Status Report #12
Saturday June 26, 1993, 2 p.m. CDT
The Endeavour crew completed flight day six activities about 1:30 p.m. CDT
today. Saturday's work focused on several experiments in the Spacehab module
and one experiment carried in the middeck.
The diagnostic equipment portion of the Tools and Diagnostics System experiment
was performed by Nancy Sherlock. Using electronics test instruments including
an oscilloscope and electrical test meter, Sherlock conducted tests on a mock
printed circuit board and communicated with ground controllers via computer
messages on suggested repair procedures and their results.
Brian Duffy and Jeff Wisoff worked on several test setups of the Fluid
Acquisition and Resupply Experiment, or FARE, which evaluates techniques that
could be used to develop methods of refueling spacecraft in orbit. By
transferring water between two transparent tanks on Endeavour's middeck,
engineers can evaluate how the fluids behave while the shuttle's steering jets
are fired for small maneuvers.
Janice Voss worked on the Liquid Encapsulated Melt Zone, or LEMZ, experiment
which uses a process called floating zone crystal growth. The low- gravity
conditions of space flight permit large crystals to be grown without touching a
container. This particular experiment uses a liquid to surround the indium
bismuth material as it is melted, then solidified into crystal form.
Researchers expect to produce large single indium crystals that may pave the
way for use of the LEMZ hardware to test materials of commercial interest on
future missions. If processes can be refined to commercially produce large,
pure crystals such as gallium arsenide, they could contribute to the next
generation of high-speed computer, optics and sensor systems.
The test calling for shutting down one of Endeavour's fuel cells was terminated
when the hydrogen reactant valve would not close. Fuel cell number three was
restarted without incident and is performing normally. Flight controllers are
evaluating whether to try the test again later in the mission. The study is
designed to expand the electrical generation engineers' knowledge of fuel cell
performance when turned off and then back on while in space. At least three
tests on separate shuttle flights are planned in preparation for prolonged
shuttle stays at the space station when a fuel cell would need to be
temporarily turned off.
Endeavour continues to perform well, allowing the crew to dedicate its work
days to the Spacehab module experiments.
