4/29/93: TECHNOLOGY TRANSFER CENTER TO WORK WITH SDIO TO AID INDUSTRY
Charles Redmond
Headquarters, Washington, D.C.
April 29, 1993
RELEASE: 93-77
The National Technology Transfer Center (NTTC), Wheeling, W.Va., under
an agreement with the Strategic Defense Initiative Organization (SDIO), will
assist SDIO in the operation of its Technology Applications Information System
and to help identify items which should be included in the technology
applications database.
The agreement calls for the NTTC, which is funded by NASA and works in
cooperation with other federal agencies, to help the Strategic Defense
Initiative Technology Applications Program coordinate the transfer of
SDIO-developed technology into the commercial sector.
The NTTC also will identify appropriate public and private technology
organizations which may be interested in SDIO-developed technology or
innovations and will provide information to these additional organizations.
NASA's Chief of Technology Transfer Programs, Frank Penaranda said
"this agreement marks an important step in our efforts to establish the NTTC as
a national resource for federal technology transfer."
The NTTC Director, Lee Rivers, said "the affiliation with the Strategic
Defense Initiative Office represents a natural partnership. SDIO has produced
cutting edge technologies that are ready to be developed into products for the
market place. The NTTC can help make those technologies available to U.S.
companies."
The SDIO Deputy Director for their technology applications office, Nick
Montanarelli, said "we believe the combination of NTTC and SDIO efforts will
serve to enhance the NTTC's current and emerging capabilities and will result
in a synergism between the two offices. The technology transfer objectives of
both organizations will be enhanced.

Mission Control Center Status Report #8
MISSION CONTROL CENTER
STS-55 Status Report #8
Thursday, April 29, 1993, 3 a.m. CDT
Columbia's crew has spent a quiet night forging ahead through a variety of
science experiments in the German Spacelab, including the first powering up of
a German Space Agency-developed robot arm.
The robotic experiment, called ROTEX, will investigate various methods of
controlling a robotic arm, including remotely controlled operations from the
ground, operations controlled by the crew aboard Columbia, totally automatic
operations and other modes. The device will also assist designers in
evaluating how well they have planned for the effects of weightlessness on the
various joints and sensors of the arm as well as the joystick controller for
it.
Experiments in the physics of fluids in weightlessness and the behavior of
various dissolved solutions in microgravity also continued, as did checks of
plants, cells and the aquatic animals aboard.
Early yesterday evening, the crew capped a line that had fed nitrogen into a
now unused waste water tank on Columbia, thus allowing the nitrogen system to
be turned back on to fully pressurize Columbia's potable water supply tanks.
That system is now in fully normal operation. Flight controllers did note a
shut down of Columbia's flash evaporator system, or FES, when a dump of excess
potable water was begun shortly afterward. The excess water was then dumped
overboard via an exterior nozzle that dumps it much quicker than the FES does.
The FES is a preferred method for dumping water at times during this mission
because it dumps the water in much finer particles than the usual nozzle dump,
thus lessening the chance the dumped water would contaminate any of the
astronomical and Earth observation equipment. Water can be dumped by the
nozzle if Columbia moves to an orientation that ensures the water stays clear
of the cargo bay.
Flight controllers believe the FES may have ice in the core and can be
restarted by flushing it with warm water, a procedure that has been done on
several shuttle flights where similar problems occurred. However, they are
continuing to study that plan since there is no urgent need for the FES.
Columbia is in a 161 by 160 nautical mile orbit, circling Earth each 90
minutes.

MISSION CONTROL CENTER
STS-55 Status Report #9
Thursday, April 29, 1993, 11 a.m. CDT
Columbia continues to perform well on the fourth day of the D-2 German Spacelab
mission. Electricity conservation measures initiated yesterday have added more
than three hours to the 16 hours of mission extension time gained since launch.
The goal is to accumulate enough extra fuel used to generate electricity to add
one day onto the mission for additional science work in the Spacelab module.
Mission managers are optimistic that turning off equipment not critical to
science work or Orbiter operations will gain the electricity reserve needed for
the extra day.
The STS-55 crew held a press conference at 6:20 a.m. CDT with German
television reporters just before the handover from the Red Team to the Blue
Team of Steve Nagel, Tom Henricks, Jerry Ross and Ulrich Walter.
Henricks and Nagel performed a trim burn at 7:24 a.m. CDT using the reaction
control jets to slightly adjust Columbia's orbit from 161 x 160 nautical miles
down to 161 x 158 nautical miles. Columbia has been gaining energy because of
the small maneuvers to point the Modular Optical Multispectral Scanner, known
as MOMS, at the Earth. The digital images will be used to produce topographical
maps by automatic data evaluation processes for the first time. MOMS
resolution permits details of only a few yards to be recognizable.
While Ross and Walter work on the experiments in Spacelab, Henricks and Nagel
assembled a cable that will power both Orbiter refrigerator/freezers. The crew
will periodically check temperatures through a pair of multimeters to be hooked
up along with the cable during the second OR/F maintenance procedure, likely to
be scheduled late today or Friday. Researchers would like to have the primary
OR/F back in operation as a back-up to the secondary unit that has been
operating since Monday. The biological samples of blood, urine and saliva
require stable storage conditions until returned to medical investigators in
Germany and the US.
Flight controllers are studying options to thaw out a suspected ice formation
in the flash evaporator system's core. Since the excess supply water created
by Columbia's fuel cells can be dumped through exterior nozzles, it is not
urgent to immediately turn on the FES. A procedure used on previous Shuttle
missions when similar conditions with the FES were encountered may be used
later in the flight. Warm water can be flushed through the FES core to restart
it.
At about 9:50 a.m. CDT, (MET 3/00.03), the cooling system radiator panels were
deployed on both payload bay doors. The two forward radiator panels on each
payload bay door can be raised away from the door to allow additional head
rejection from both sides of the radiator panel. Radiators in the deployed
position are about 30 percent more efficient because they reject heat from both
top and bottom. With the flash evaporator system shut down due to a suspected
ice formation in its core, the supplemental cooling will maintain the
temperatures required for Spacelab experiment operations.
Although the Flight Control team and the crew have had a few technical problems
with Columbia, mission managers expect no serious impact to Columbia's full
nine-day science mission.

Mission Control Status #7

STS-55 Status Report #7
Wednesday, April 28, 1993, 5:30 p.m. CDT
The STS-55 crew is closing the books on the waste water tank anomaly today as
they perform a procedure to isolate the suspect tank from the pressurization
system for Columbia's supply water tanks.
The procedure which got underway at about 5:15 p.m. Central, required the crew
to install a quick disconnect device to the waste tank's nitrogen line. Once
the quick disconnect is in place, crew members will be able to pressurize the
supply water tanks normally, returning the Urine Monitoring System, the
Personal Hygiene System and the galley to their normal operating modes.
Earlier today, the crew and flight control team members verified the
contingency waste collection bag installation by performing a short waste water
dump. All systems worked as expected as more than 20 pounds of waste liquid
was expelled from the orbiter.
Payload activities also went well today as Mission Specialist Jerry Ross and
Payload Specialist Ulrich Walter performed materials science and biological
science experiments. In one experiment, Walter used the fluid physics module
to vibrate columns of water so that pressure sensors could determine their
dynamics. In the meantime, Ross worked with experiments that looked at the
diffusion rates of molten salts and used the Holographic Optics Laboratory for
investigations of heat mass and particle transport.
Walter and Ross also joined Commander Steve Nagel and Pilot Tom Henricks for an
in-flight press interview with two German television stations.
