5/07/93: ADVANCED COMMUNICATIONS TECHNOLOGY SATELLITE MOVED TO VPL
(VERTICAL PROCESSING FACILITY TODAY)
George H. Diller May 7, 1993
KSC Release No. 54-93
Moving only one mile, the Advanced Communications Technology Satellite
(ACTS) passed its latest major milestone this morning. The spacecraft was
transported from the Payload Hazardous Servicing Facility (PHSF) to the nearby
Vertical Processing Facility (VPF) in the KSC Industrial Area.
This milestone signifies the end of integrated testing between ACTS and
its upper stage booster, a Transfer Orbit Stage (TOS). The tests verified that
the two payload elements operate in unison. Prior to mating, each flight
element was readied and tested separately, ACTS in Hangar AO on Cape Canaveral
Air Force Station and TOS in the PHSF.
Now in the VPF, the ACTS-TOS payload will use the unique Cargo Integrated
Test Equipment (CITE) for the Interface Verification Test (IVT). This test
will demonstrate the payload's compatability and readiness to be mated with the
Space Shuttle Discovery. It will also prove that the payload can be checked out
by the astronauts before deployment, and that the planned deployment sequence
can be executed as intended. All of these tests will be repeated after
ACTS-TOS is installed into Discovery's payload bay next month. The IVT is
scheduled for May 19.
The ACTS-TOS payload is scheduled to be moved to Pad 39-B on June 22 based
on a mid-July targeted launch of STS-51. ACTS is designed to test advanced
experimental satellite communications concepts.

% Endeavour launch targeted for June 3;
% SSC to host International Science and Engineering Fair.
Endeavour's STS-57 mission will begin a new era in the commercial development
of space. The STS-57 mission will also retrieve the EURECA satellite and the
crew members will have the opportunity to use experiments designed by and for
students.
The major payload of the mission, Spacehab, is a privately-developed mid-deck
augmentation module. The experiments inside the Spacehab include
investigations ranging from drug improvement, feeding plants, cell splitting, a
soldering and high-temperature melting of metals.
The crew members on Endeavour's STS-57 mission will also perform a 4-hour
spacewalk. The extravehicular activity (EVA) is a continuation of a series of
spacewalks designed to expand the EVA experience levels of astronauts, flight
controllers and instructors in anticipation of erecting the space station.
Space Shuttle Endeavour's mission is scheduled to launch June 3, 1993 . The 6
day mission will conclude with a landing at the Kennedy Space Center.

5/07/93: FASTEST SUPERCOMPUTER CAN BOOST U.S. AEROSPACE INDUSTRY
Drucella Andersen

Ames Research Center, Mountain View, Calif.
RELEASE: 93-80
NASA's Ames Research Center, Mountain View, Calif., has added a new
computer to its Numerical Aerodynamic Simulation (NAS) supercomputer complex
that will boost the computing power of the system by more than six times.
Research scientists use the NAS computers by programming a proposed new
aircraft design into the supercomputer. The computer then solves equations
millions of times to replicate the "real" air flow around the proposed aircraft
design.
"These advances in supercomputer aerodynamics are important because
aerospace is the largest favorable contributor to the U.S. balance of trade --
$30 billion last year," said Victor L. Peterson, Ames' Deputy Director. "The
U.S. share of the world aerospace market has been declining, but machines like
the C90 should help reverse this trend."
The NAS is a unique national facility linking approximately 1,400
industry, university, government and NASA users via a high-speed, wide-area
network known as AEROnet.
The new Cray Y-MP C90 supercomputer, the world's fastest, is now in
full operation after completing its acceptance tests. It routinely will
perform more than 6 billion floating points per second (FLOPS), up from 1
billion FLOPS for the current NAS system. FLOPS is a measure of a computing
system's speed in doing basic arithmetic operations.
The C90 is one of the newest "parallel Processing" computers, which use
many processors to work simultaneously on various parts of a problem. The C90
has processors and a memory capacity of 256 million words. An upgrade to 1
billion words of memory is scheduled for September. Cost of the system is $48
million.
For 20 years, Ames has worked closely with supercomputer makers on
advanced hardware and software to reach the hyper-speeds needed for computer
simulation of aerodynamics. Ames is NASA's lead center for supercomputer
research. Its supercomputer systems and facilities are the most advanced in
the aerospace field and among the best in the world.
According to Dr. F. Ron Bailey, Ames' Director of Aerophysics, speeds
for NASA's next large computer, to be acquired in 3 or 4 years, might well do
around 50 billion FLOPS. Speeds could reach about a trillion FLOPS by around
the year 2000.

STS-55 LANDING STATEMENT 5/6/93
The STS-55 Spacelab D-2 mission came to a conclusion this morning after
completing 160 orbits, and traveling over 4.1 million miles. Columbia's main
gear touched down at 9:30 CDT on runway 22 at Edwards Air Force Base in
California.
The planned KSC landing was diverted to California due to unacceptable weather
conditions in the Central Florida area. Preliminary assessments of Columbia
show the orbiter to be in good shape following the 10-day flight. Engineers
have reported that Columbia's protective tiles received 97 dings, with only
14 being an inch or greater in size. A ferry flight schedule has yet to be
established, but Columbia is expected to return to KSC by the middle of next
week.
