1/29/93: KSC BASE OPERATIONS CONTRACT AWARD PROTESTS SETTLED
Mark Hess
Headquarters, Washington, D.C. January 29, 1993

Kennedy Space Center, Fla.
RELEASE: 93-18
NASA announced today that the protests of EG&G Florida, Inc., BAMSI
Inc., and Westinghouse KSC Company, Inc. have been settled on the Kennedy Space
Center (KSC) Base Operations Contract (BOC) procurement.
NASA had selected Lockheed Space Operations Co. on Nov. 17, 1992, for
negotiations leading to award of the BOC. The three companies protested the
selection to the General Services Administration Board of Contract Appeals in
early December.
Settlement was prompted by the determination that certain deficiencies
in the agency's activities occurred during the original proposal submission and
discussion phase of the procurement. This resulted in a deficiency in certain
critical information which remained unrequested and therefore, unavailable for
NASA's source evaluation board to fully consider and evaluate.
As part of the settlement, NASA will rescind its original selection.
An amendment to the BOC solicitation also will be issued. Each of the four
competitors then will have the opportunity to submit a revised proposal.
Selection of an awardee is expected to occur sometime during late summer.
The BOC provides a wide variety of services to KSC, primarily in the
area of management, operation, maintenance and engineering for KSC facilities
and utilities, technical and administrative support operations, and health,
fire and security services. The BOC will be a cost-plus-award fee contract,
with an incentive fee feature, for an initial period of 4 years with three
priced 2-year options.
EG&G Florida, Inc., the incumbent contractor, will continue to provide
base operations support during the recompetition period.

The Kennedy Space Center team working on Columbia to ready that orbiter for its
upcoming STS-55 D-2 Spacelab mission reports they will roll Columbia to the
Vehicle Assembly Building on the evening of Feb. 2, next Tuesday. Mating of
Columbia to its external tank and solid rocket boosters will begin the next
day.
KSC management will hold its launch readiness review on Monday, Feb. 8. The
NASA Office of Space Flight management's formal Flight Readiness Review will be
held at KSC on Wednesday, Feb. 11. The launch dress rehearsal with the
astronaut and ground launch team crews will take place on Feb. 11 and 12, with
the simulated launch time at 11:00 am EST on Feb. 12.
Preparations on Columbia are proceeding on a schedule which could allow the
launch of the STS-55 mission in late February. The STS-55 mission is the second
dedicated German research flight; the first was the D-1 mission which flew on
STS-61A in November 1985. This flight is scheduled as an 8-day and 22-hour,
seven- crewmember mission with the Spacelab long module and a variety of
scientific discipline investigations. This mission's major Spacelab facilities
will continue the exploration of fluid physics and human physiological changes
in microgravity. Additional experiments will continue the investigations of
the Earth's atmosphere, the surface topography of the planet, and include
additional investigations in galactic astronomy and technology development.
Briefings on the mission objectives and science experiments will be held at the
Johnson Space Center next Wednesday and Thursday, Feb. 3 and 4. The briefings
will be carried live on NASA Select television, and will begin at 9:30 am EST
on Wednesday.
Also, a post-mission briefing by the crew of the last mission, STS-54, will be
held at JSC on Monday, Feb. 1. This also will be shown live on NASA Select
television, beginning at 4:00 pm EST.

NASA Administrator Daniel Goldin earlier this week awarded famed NASA test
pilot Scott Crossfield the NASA Distinguished Public Service Medal for
Crossfield's many contributions during his 50 year public service career. The
award occurred in a Capitol Hill ceremony honoring Crossfield following his
retirement from federal service.
Crossfield played an early and pivotal role in NASA's highly-successful X-15
research program after having flown most of the earlier X-planes for NASA's
precursor agency-the National Advisory Committee for Aeronautics. Of late,
Crossfield had been the technical consultant to the House of Representatives
Committee on Science and Technology for the National Aero-Space Plane program.
Crossfield joined the NACA in 1950 and flew the Bell Aircraft X-1 and later in
1953 flew the Douglas Aircraft D-558II Skyrocket at twice the speed of
sound-being the first person to accomplish that feat.
Crossfield later became the chief engineering test pilot for North American
Aviation and was the driving force behind the development of the record-setting
X-15 rocket plane. The X-15 took humans to the edge of space for 199 total
flights. North American built three of these rocket-planes. The first one is
now on display at the Smithsonian National Air and Space Museum, the second one
is on display at the Air Force Museum at Wright-Patterson Air Force Base. The
third was destroyed in a fatal crash which also killed USAF test pilot Mike
Adams in 1967.

Flight controllers at the Jet Propulsion Laboratory report the Ulysses
spacecraft is now in a highly inclined elliptical orbit and is presently almost
17 degrees south of the Plane of the Ecliptic. The first solar polar passage
will occur in 1994. JPL reports Ulysses continues to perform fine and is
taking data on the interplanetary medium.
JPL also reports that the two Voyager spacecraft are also doing fine. Voyager
1 is now 4.7 billion miles (7.6 billion kilometers) from the Sun heading
outward. Voyager 2 is 3.6 billion miles from the sun (5.8 billion km) and also
heading outward. Both spacecraft were launched in Fall 1977 and use
radioisotope- thermoelectric-generators which were built in 1976 and which are
still providing electric power for the spacecraft nearly 17 years later. The
two Voyagers along with Pioneers 10 and 11 are providing scientists with
continuing data on the extreme distant composition of the solar wind. The
radio signals from the four spacecraft are also being used as part of
gravitational studies of the mass and objects in our solar system.

TOPEX STATUS 12/22/92
TOPEX/POSEIDON STATUS REPORT
December 22, 1992
The satellite continues to be operational and healthy.
On Dec. 21, the ninth 10-day repeat track cycle was completed.
A second orbit maintenance maneuver was also
successfully performed yesterday at the start of cycle 10. Two
small thrusters were fired for four seconds to raise the
satellite's 830 mile altitude by about 22 feet. The fine-tuning
of the orbit maintains the repeating ground tracks within the
desired band.
On Saturday, Dec. 19, the altimeter experienced a 17
hour loss of altimeter data. Engineering data was received
during this gap. While the cause of the data loss is still under
investigation, a single event upset is thought to be the likely
culprit. The data gap ended when the altimeter reset itself.
The altimeter is currently tracking nominally.
On Dec. 10, the project participated in a special
TOPEX/Poseidon session at the American Geophysical Union meeting
in San Francisco. Participants from NASA and CNES confirmed
that the initial science data is good and said they are pleased
with how quickly data is being processed and made available to
the science community.
Early results from the NASA Altimeter have been
processed to show wave height, eddies and ocean topography.
Scientists report that these preliminary results show that the
satellite is working as expected.
On Dec. 8 the first improved attitude control system
calibration parameters were sent to the satellite resulting in
dramatic improvement in the altimeter pointing and its
variations. Today, the altimeter bias offset was changed by 0.1
degree to further reduce the small altimeter pointing error.

TOPEX STATUS 1/18/93
TOPEX/POSEIDON STATUS REPORT
January 18, 1993
The satellite is healthy and all instruments continue
to operate normally.
The science data team has delivered the tenth 10-day
science data cycle to JPL's Physical Oceanography Data Active
Archive Center. This satisfies the fight team's goal of
providing 10 cycles of data to the principal investigators for
experiment processing and presentation at a verification workshop
to be held at JPL Feb. 22 to 25, 1993.
The satellite pointing remains good since the attitude
control system calibration results were implemented in late
December. Consequently, the altimeter performance is good and
100 percent of the data are typically received from three daily
playbacks.
The batteries are performing well and show no signs of
degradation. The flight team continues to implement "tender
loving care" for the batteries following all recommendations of
the project battery team to ensure that they do not overcharge
the batteries.
Today the French solid-state altimeter was turned on so
the French can take data when the satellite overflies the Centre
National d'Etudes Spatiales verification site in the
Mediterranean Sea.
Since launch on Aug. 10, 1992, the flight team has sent
more than 1 million commands to the satellite.

6. GROUND SEGMENT
The ground segment performed nominally during the
reporting period with the except during the passes on
1st January.
A problem in the MCCC (Mission Control Computing Center)
at JPL caused all data to be tagged with the year 1992 instead of
1993. The real-time SCMS was not able to file this data since the
timekey was earlier than the first record in the history file. The
history files on the backup machine were cleared and this
was used to file data while the problem was traced.
Once the problem was fixed data were recalled into the
real-time machine and properly filed in the history
files. No data were lost.

The items listed below are available to you and your crew after
crash-landing on the moon. Rank the items from most to least
important (1-15) in allowing all of you to reach the rendezvous
point of a rescue craft's landing site.
ITEMS:
box of matches
food concentrate
50 feet of nylon rope
parachute
portable heating unit
case of dehydrated milk
2, 100 lb. tanks of oxygen
moon constellation map
self inflating life raft
magnetic compass
5 gallons of water
pistol with 6 bullets
self-igniting signal flares
first aid kit with hypodermic needles
solar powered FM transceiver
-------
Individuals should be able to discuss their rationale for
the ranking given each item.
-------
The following are rankings and rationale given by "experts."
Rankings are in parentheses.
matches: (15) No air on moon so matches will not burn.
food: (4) Efficient means of supplying energy requirements.
rope: (6) Useful in scaling cliffs or use in case of emergency.
parachute: (8) Possible use as sun shield.
heater: (13) Not needed unless on dark side.
pistol: (11) Possible means of self propulsion.
milk: (12) Bulkier duplication of energy source.
oxygen: (1) The most pressing survival requirement.
constellation map: (3) Primary means of navigation.
raft: (9) Carbon dioxide bottle possible propulsion source.
compass: (14) Useless, lunar magnetic fields are not polarized.
water: (2) Replacement of Tremendous liquid loss on lighted side of moon.
flares: (10) Distress signal when rescue ship is sighted.
First Aid Kit: (7) Needles for medicines and vitamins fit special
aperture on suit.
FM Transceiver: (5) For communication with rescue ship on line of sight.
------
Individual student rankings can be compared with a group
ranking or expert rankings. Error points can be calculated
as the absolute difference between individual and group or expert
rankings.
Rationale for some items could move them to a higher rank.
For example, the compass is worthless for finding direction,
however, the transparent cover could be used as a reflective
signaling device.
