Endeavour is now safely in its planned 185-mile-high orbit (298 kilometers)
with all systems performing nominally. A few minor glitches occurred prior to
launch, including the loss of some consoles at the Kennedy Space Center launch
control room and resetting the main launch sequencer computer. These glitches
notwithstanding, the countdown and launch were completely nominal according to
Robert Sieck, NASA launch director, and Brewster Shaw, Shuttle safety chief.
Liftoff was delayed by about 10 minutes because of the combination of minor
problems. The orbiter crew also had to reconfigure the auxiliary power unit
cooling system because of what appeared to be the freeze-up of the unit's
cooling system. This will have no impact on the mission and will probably
resolve itself as a natural consequence of the ice evaporating, Shaw said.
The STS-54 flight crew is set to deploy the fifth Tracking and Data Relay
Satellite at 3:05 pm EST today. Following the deployment of the TDRS
spacecraft, the crew will begin activation of a number of secondary experiments
and later this evening will begin the first scan of the diffuse X-ray
background using a spectrometer supplied by the Goddard Space Flight Center.
This experiment will scan the sky measuring the distribution of energy in the
X-ray wavelengths to try and provide astronomers with evidence as to the source
of this diffuse background illumination. A leading theory states the radiation
is coming from the hot gas plasma surrounding our solar system.
On Friday, the Endeavour crew will participate in a space-based science lesson
with students from four schools located in New York, Ohio, Michigan and Oregon.
The astronaut-teachers will use ordinary toys to demonstrate several of the
fundamental laws of physics.
NASA Select television will provide continuous, live, coverage of the mission
throughout the next five days, concluding with the nominal end-of-mission
landing at the Kennedy Shuttle Landing Facility on Tuesday, Jan. 19, at 8:24 am
EST. Also, NASA will again provide a two-hour edited program containing daily
highlights of the mission on a different satellite for the benefit of
interested individuals and organizations in Alaska and Hawaii. Beginning with
this mission, the two-hour programming will be on transponder 19 (4080 MHz,
audio at 6.2 and 6.8 MHz) on the Galaxy 6 satellite located at 99 degrees West
Longitude.

NASA Administrator Daniel Goldin yesterday announced the appointment of Deidre
Lee as Acting Associate Administrator for Procurement. Goldin said "Deidre Lee
brings experience, considerable skills and boundless energy to this position at
a time when NASA procurement activities are undergoing dynamic reform." Prior
to joining NASA's Johnson Space Center in 1984, Lee had been involved in
procurement activities for systems and logistics commands for the Air Force.
* * * * * * * * * * * * * * * *
In a related item, Administrator Goldin has called for major improvements in
the way in which NASA transfers technology. Goldin reported on a special
technology transfer assessment team report, which was made public this past
Friday.
The report said that NASA has no comprehensive documentation to explain the
process of technology transfer and that much of the agency's technology
transfer activities are too slow to meet industry needs. The report said that
technology should be exchanged with industry representatives at every stage
rather than at the completion of the development process, as it is now done.
Goldin said that NASA will seek from the user community methods and ideas which
will allow for faster and more thorough transfer of NASA-developed technology.
To that end, the Office of Advanced Concepts and Technology was created to
better meet the needs of industry, the university community and NASA.

STS-53 Launch 12/2/92
Discovery lifted off this morning at 8:24 am EST following a
nearly-90-minute-long delay because of ice which had formed on the outside of
the External Tank in several areas. Discovery and its five-person crew are now
in a circular, 233 statute-mile-high orbit, with the payload bay doors open.
The launch itself, once underway, was completely nominal, as were the two
circularization firings of the orbiter's maneuvering system engines.
Discovery's 57-degree inclination mission is scheduled for a nominal
end-of-mission landing at the Kennedy Space Center shuttle landing strip on
December 9, at 12:53 pm EST.
At the post-launch press conference this morning at KSC, launch director Robert
Sieck and shuttle safety chief Brewster Shaw said this launch culminated a year
which had seen 7 of 8 launches go within a two-hour period of their scheduled
time. Sieck and Shaw also commented on the increasing efficiency of their
processing activities at Kennedy. Shaw noted that in the past two years orbiter
processing has been reduced by more than several thousand man-hours with no
sacrifice in either safety or processing. Shaw said they also were seeing a
decreasing number of change-out requests while the orbiters were in their
hangers and a decreasing number of problem reports. There also have been fewer
and fewer on-orbit anomalies as the various orbiters have flown, Shaw noted.
Shaw said he felt very comfortable flying eight missions a year and felt the
nation's space shuttle launch activities were achieving a proper level of
maturity. Shaw also said that, based on the findings of a special team
commissioned just about one year ago and on discussions held yesterday and this
morning regarding the impact on launch commit criteria of cold temperatures, he
felt NASA flight management was moving towards a modification in these rules.
Because STS-53 is a classified mission, there will be limited NASA Select
television coverage until DOD primary operations have concluded. Also, for
this mission only, there will be no NASA Select daily two-hour summaries made
available via satellite to Alaska and Hawaii.

STS-54 INSIGNIA
Designed by the crewmembers, the STS-54 crew patch depicts the American bald
eagle soaring above Earth and is emblematic of the Space Shuttle Endeavour in
service to the United States and the world. The eagle is clutching an eight
pointed star in its talons and is placing this larger star among a
constellation of four others, representing the placement of the fifth Tracking
and Data Relay Satellite (TDRS) into orbit to join the four already in service.
The blackness of space--with stars conspicuously absent--represents the crew's
other primary mission in carrying the Diffuse X-ray Spectrometer to orbit to
conduct astronomical observations of invisible x-ray sources within the Milky
Way Galaxy. The depiction of Earth showing North America is an expression of
the crewmembers and NASA's intention that the medical and scientific
experiments conducted onboard be for the benefit of mankind. The clouds and
blue of Earth represent the crew's part in NASA's Mission to Planet Earth in
conducting Earth-observation photography.

STS-54 TRDS-F/DXS Mission January 13,1993
The space shuttle Endeavour lifted off this morning at 8:59:30 EST into partly
cloudy Florida skies. Mission Control Status Reports are generally issued
several hours after liftoff, and are usually updated on a 12 hour basis,
depending on mission events. We will be posting these updates as they are
released.
Endeavour is now safely in its planned 185-mile-high orbit (298 kilometers)
with all systems performing nominally. A few minor glitches occurred prior to
launch, including the loss of some consoles at the Kennedy Space Center launch
control room and resetting the main launch sequencer computer. These glitches
notwithstanding, the countdown and launch were completely nominal according to
Robert Sieck, NASA launch director, and Brewster Shaw, Shuttle safety chief.
Liftoff was delayed by about 10 minutes because of the combination of minor
problems. The orbiter crew also had to reconfigure the auxiliary power unit
cooling system because of what appeared to be the freeze-up of the unit's
cooling system. This will have no impact on the mission and will probably
resolve itself as a natural consequence of the ice evaporating, Shaw said.
The STS-54 flight crew is set to deploy the fifth Tracking and Data Relay

STS-54 Status Report #1
MISSION CONTROL CENTER
Wednesday, January 13, 1993, 10 a.m.
Endeavour performed a normal launch and ascent to orbit this morning at 7:59:30
a.m. CST, following a few minutes long delay to allow extra analysis of
high-altitude winds and their predicted effect on Endeavour.
After reaching a 164 by 160 nautical mile orbit, the crew activated the Diffuse
X-Ray Spectrometer to allow ground commanding of the instrument to begin from
the Goddard Space Flight Center in Greenbelt, Md. The crew's main focus for the
remainder of today will be the deploy of the Tracking and Data Relay
Satellite-F scheduled for about 2:12 p.m. CST, after the satellite is checked
out and powered up.
The crew will go to sleep for their first night in orbit at 6:29 p.m. CST
today.

STS-54 Status Report #2
Wednesday, January 13, 1993, 4 p.m. CST
Tracking and Data Relay Satellite-F is cruising to its geosynchronous altitude
following its on-time deploy from the Space Shuttle Endeavour today.
Mission Specialist Mario Runco flipped the switch to deploy TDRS-F and its
Interial Upper Stage booster at 2:12 p.m. Central. Commander John Casper then
eased Endeavour away from the spacecraft, before firing the orbiter's engines
to move to a safe distance for the IUS's first rocket motor burn.
TDRS-F is NASA's fifth orbiting communications relay station. It will be held
on orbit in a "ready reserve" status, thus completing the TDRS system's
constellation of satellites. As the "ready reserve" satellite, TDRS-F will be
available to be placed into active service should one of the current satellites
fail.
With the successful deploy of TDRS-F, STS-54's other primary payload began
operations. During orbital night, the Diffuse X-Ray Spectrometer will take
measurements of the x-ray background of the solar system's interstellar medium.
This information will be used to answer questions about a nearby super nova
that scientists believe occurred about 300,000 years ago.
Endeavour began its third mission at 7:59 a.m. Central and continues to
perform well at this time. The orbiter is circling the Earth once every 90
minutes at an altitude of about 178 x 163 n.m.
