3/22/93: NASA/OHIO AEROSPACE INSTITUTE TO HOST CYBERSPACE CONFERENCE
Charles Redmond
Headquarters, Washington, D.C. March 22, 1993
Linda Ellis
Lewis Research Center, Cleveland
RELEASE: 93-50
NASA's Lewis Research Center, Cleveland, and the Ohio
Aerospace Institute will host a conference in Cleveland, March 30
and 31, focusing on and providing insights into the fascinating
new world of Cyberspace.
Cyberspace is a metaphor coined and popularized by
science fiction author William Gibson to represent the "universe"
that humans beings enter when they use computers.
The Vision 21 Symposium on Interdisciplinary Science and
Engineering in the Era of Cyberspace conference will focus on
this new metaphor and also will feature a series of speakers.
"In keeping with the conference mission to foster
speculative concepts and advanced thinking in science and
technology, this event will provide a panoramic view of the
research and technology that will assist humans in exploration
activities," said Dr. Sheila Bailey, conference Chairperson.
Bailey, who is a Lewis research physicist in the center's
Power Technology Division, also said that this new vision
includes "not only the Earth's environment and the Martian
terrain, but the artificial reality of cyberspace."
Each of the five speakers for the conference is an
interdisciplinary scientist with a unique view of the future.
Together, the speakers share a common vision of cyberspace as a
world where computers, robots and the human mind will be more
closely linked.
The speakers include Hans Moravec from Carnegie Mellon
University's Institute for Robotics, who believes that "robots
with human intelligence will be common in the next 50 years."
San Diego State University mathematician and science
fiction writer Vernor Vinge will talk about linking the mind and
the computer. His novels explore the ethical questions
associated with society's use of computers and the potential for
good and evil use of these computers.
Carol Stoker, NASA Ames Research Center scientist, who
uses remote sensing and telepresence in exploration activities
being conducted in the Antarctic, will talk about the science and
engineering challenges of using robots in the Antarctic and what
might be faced in similar expeditions to the moon or Mars.
John Dalton, NASA Goddard Space Flight Center manager for
NASA's Earth Observing System ground system, will discuss the use
of information systems to support climate research and how global
environmental models are evolving. More and more scientific
analysis of Earth environment information is using scientific
visualization methods which are themselves on the cutting edge of
computer science. Many of the new data sets lend themselves to
presentation in a "cyberspace" environment.
Dr. Myron Krueger, Director of the Artificial Reality
Corp., will discuss how humans will experience and interact with
or in cyberspace. Krueger termed the phrase "artificial reality"
to describe human interaction with computer-generated worlds.
Attendees at the 2-day conference also will have the
opportunity to tour the Ohio Aerospace Institute and the Lewis
Research Center's Graphics Visualization Laboratory. That
laboratory recently demonstrated distributed processing and
visualization by simulating the flow of air and gasses through a
turbo-jet engine P each component of which was running as a
simulation on one of over 2 dozen high-powered computer
workstations.

- offloading liquid hydrogen and liquid oxygen from external tank
- STS-55 astronauts returned to Houston at 2:30 p.m.
ISSUES AND CONCERNS:
While igniting Columbia's three main engines which began at
T-6.6 seconds the onboard computers initiated a main engine abort
sequence. Shutdown was completed at approximately T-3 seconds at
9:51 a.m. EST.
The reason for the abort appears to be that main engine #3
did not fully ignite due to a liquid oxygen preburner check valve
which apparently experienced an internal leak, causing the purge
system to be pressurized above the maximum 50 pounds per square
inch allowed. Ambient pressure would have allowed full engine
ignition to occur. The onboard computers sensed the higher than
allowed pressure in the line and terminated the main engine
ignition sequence.
While no definite schedule has been developed as yet, the
amount of time estimated to pick up the STS-55 countdown once
again is about three weeks. Schedule options are under
consideration this week.

3/22/93: SPACELINK NOTE: The countdown for the STS-55 Spacelab D-2 mission
was halted at T-3 seconds after the redundant set launch sequencer inititated
an on-pad abort just after main engine start. We'll post additional
information on the launch as it becomes available. Previously issued

STS-55 LAUNCH DATE SET FOR MARCH 21,1993
Ed Campion March 12, 1993
Headquarters, Washington, D.C.

Release No. 22-93
NOTE TO EDITORS: NEW LAUNCH DATE FOR STS-55 MISSION
NASA Managers today set March 21, 1993 as the launch date for Shuttle
Mission STS-55 which will see Space Shuttle Columbia and her 7 member crew fly
a mission dedicated to the German Space Agency. The major payload for STS-55,
the pressurized spacelab module - designated as Spacelab-D2 for this flight -
will allow the astronauts to conduct a wide range of experiments in the
microgravity environment of space.
The launch window on March 21 opens at 9:52 a.m. EST. Following launch,
Columbia's crew will be divided into two teams each working a 12-hour shift, so
that science operations can be carried out around the clock. The Spacelab-D2
mission duration is planned for 9 days and will conclude with a landing at
Kennedy Space Center's Shuttle Landing Facility.
Columbia's launch date will have an influence on the next mission to be
flown. Space shuttle Discovery, flying the ATLAS 2 payload on Shuttle Mission
STS-56, now targeted for launch sometime around April 7th. The actual launch
date for STS-56 will be set at a Flight Readiness Review meeting which will be
held approximately two weeks before launch.
"The Shuttle team has done a great job in addressing and closing issues
such as the hydraulic flex hose problem and putting together a new plan for
processing activities" said Shuttle Director Tom Utsman. "Also the cooperation
we've received from the United States Navy, the United States Air Force and
Hughes Space and Communication Company made the March 21st launch of Columbia
possible."
STS-55 STATUS 3/08/93
DAILY NEWS/TV SKED
Daily News
Monday, March 8, 1993
Managers and engineers will continue to asses the launch schedule impact
attributable to inspections of the hydraulic flex hoses and clean-up and
inspection of the aft engine compartment and number two main engine. An
assessment of a new schedule will be made available early this week.
2/26/93: MARCH 14 SET AS LAUNCH DATE FOR STS-55 MISSION
Ed Campion
Headquarters, Washington, D.C. Feb. 26, 1993

Kennedy Space Center, Fla.
KSC Release No. 16 - 93
NASA managers today set March 14, 1993 as the launch date
for Shuttle Mission STS-55 which will see Space Shuttle Columbia
and her seven-member crew fly a mission dedicated to the German
Space Agency.
The major payload for STS-55, the pressurized spacelab
module - designated as Spacelab-D2 for this flight - will allow
the astronauts to conduct a wide range of experiments in the
microgravity environment of space. Some 90 experiments are
planned during the mission.
The launch announcement follows the removal, inspection and
replacement of the high pressure oxidizer turbopumps on
Columbia's three main engines. The pump changeout came after a
search of processing paperwork could not conclusively determine
that the pumps were equipped with a newer version of turbine tip
seal retainers. The seals minimize the flow of gas around the
tips of the turbine blades to enhance pump performance and the
retainers hold the seals in place.
The launch window on March 14 extends from 10 a.m. until
12:30 p.m. EST. Following launch, Columbia's crew will be
divided into two teams, each working a 12-hour shift, so that
science operations can be carried out around the clock. The
Spacelab-D2 mission duration is planned for 9 days and will con-
clude with a landing at Kennedy Space Center's Shuttle Landing
Facility. This date was chosen primarily because it was the
first open date on the Eastern Range during this time frame.

STS-55 REVIEW COMPLETED, LAUNCH DATE TO BE SET LATER
Ed Campion
Headquarters, Washington, D.C. February 11, 1993
George Diller
Kennedy Space Center, Fla.
NOTE TO EDITORS: N93-7
NASA managers today completed their review of the flight readiness of
Shuttle Mission STS-55, a mission dedicated primarily to the German Space
Agency for research in life and microgravity sciences.
Because of a decision reached yesterday to remove and replace
Columbia's high pressure oxidizer pumps, a launch date for the mission was not
set. Managers are still assessing the time it will take to perform the work
and resume launch preparations. Tom Utsman, Director of the Space Shuttle
Program, said a launch date for STS-55 would be set the last week in February.
The pumps being replaced feed super cold oxygen to the Shuttle's three
main engines. They are being removed because a search of processing paperwork
could not conclusively determine that the pumps are equipped with a newer
version of turbine tip seal retainers. The tip seals minimize the flow of gas
around the tips of the turbine blades to enhance pump performance and the
retainers hold the seals in place.
The major payload for Space Shuttle Columbia and her 7 member crew is
the pressurized Spacelab module - designated Spacelab-D2 - which will allow the
astronauts to conduct a wide range of experiments in the microgravity
environment of space. Some 90 experiments are planned during the mission.
This will be the 14th flight of the orbiter Columbia and the 54th Space
Shuttle mission.
