KSC SHUTTLE STATUS REPORT -- 12 SEPTEMBER 1990
LAUNCH ADVISORY FOR SHUTTLE MISSIONS STS-35 AND STS-41
------------------------------------------------------
NASA managers today set Tuesday, September 18, 1990 as the launch date for
Space Shuttle Columbia and the STS-35 Astro-1 mission. The decision on the new
launch date follows the removal, replacement and testing of the liquid hydrogen
recirculation pump package in Columbia's main propulsion system.
Launch of Columbia and the STS-35 mission was scrubbed on September 5 when high
concentrations of liquid hydrogen were detected in the aft compartment of the
orbiter. Subsequent tests showed the leak came from the vicinity of the recir-
culation pump package.
During leak check operations following installation of the new recirculation
pump package, technicians found a crushed seal on the prevalve of the main
propulsion system. The seal is part of a detent cover. The prevalve is the
main hydrogen valve which supplies hydrogen to Space Shuttle Main Engine #3.
The detent holds the prevalve in place in the open position.
Helium leak checks indicated the seal was within specification, however, this
particular detent cover had an order of magnitude greater leak than other
detent covers. Alert technicians and engineers decided to investigate further
and discovered the damaged seal. Engineers believe the location of the seal
and the nature of the damage to the seal make it a prime suspect as the cause
of the hydrogen concentrations seen in the aft of Columbia during tanking
operations.
The seal in question was replaced following Columbia's last flight (STS-32,
1/90), when an inspection for possible corundum contamination of the main pro-
pulsion system was conducted. Engineers believe the seal was damaged during
the post-inspection installation and remained undiscovered until yesterday.
Countdown for the launch of Columbia is scheduled to begin on Saturday, Sept.
15 at 1:00 a.m. EDT at the T minus 43 hour mark. The 1 hour, 39 minute launch
window on Sept. 18 opens at 1:28 a.m. EDT and closes at 3:07 a.m.
Space Shuttle Discovery and the STS-41 mission will be launched as early in the
launch window (Oct. 5-23, 1990) as possible. Current scheduling indicates a
likelihood of launching on October 8 or 9, but a few days either side are pos-
sible, depending on actual test and preparation times needed. The actual
launch date for Shuttle mission STS-41 will be set at the flight readiness
review, currently scheduled for Sept. 24-25.
Discovery's freon cooling loop #1, which has given indications of a small leak
since leaving the Orbiter Processing Facility, has undergone special testing.
After review of the test data, Shuttle managers have determined that this
condition can be safely flown in its present state. Launch preparations will
include topping off the freon system of Discovery a few days before launch
which will keep the freon level well above the amount needed to support Shuttle
operations during the 4-day mission.jdbaker@athena.mit.edu (09/14/90)

In an article I posted in July, quoting Jim Westphal's description of the problems with HST's mirror, they can't correct for spherical aberration using the actuators because they were designed to correct for astigmatism in the system, and were specifically meant to NOT introduce any spherical aberration by being placed at the nodal positions for that type of aberration. They are therefore unable to correct for the mirror aberration using the actuators. As for your other question concerning the "spectacular" photos, they have recently released some data of SN 1987a and a number of other objects which have been recently observed by HST. Check out MIT's Center for Space Research (I am sure that someone there would have those photos somewhere). ------------------------------------------------------------------------------- Irwin Horowitz |"Suppose they went nowhere?"-McCoy Astronomy Department |"Then this will be your big chance California Institute of Technology | to get away from it all!"-Kirk irwin@romeo.caltech.edu | from STII:TWOK ih@deimos.caltech.edu | -------------------------------------------------------------------------------

In rec.arts.startrek there is currently a thread about previous vessels named Enterprise. I believe this short excerpt may be of interest to readers of this group The 3rd and most famous early Enterprise was also a schooner. It was built by Henry Spencer at Baltimore, Maryland in 1799.
