KSC SPACE SHUTTLE PROCESSING REPORT - TUESDAY, MARCH 28, 1989
STS-30 - ATLANTIS (0V 104) - PAD 39-B
Technicians at the pad have installed two of three high
pressure oxidizer turbo pumps (HPOTP) on the main engines. The
third HPOTP will be installed after hypergolic propellants have
been loaded onboard the ship.
Preparations are underway for loading nitrogen tetroxide and
monomethylhydrazine into Atlantis' onboard storage tanks. As part
of the hazardous propellant loading operation, hydrazine will be
loaded into the orbiter's auxiliary power units and the booster
hydraulic power units. The actual loading operation is scheduled
to begin Wednesday evening and all day Thursday.
The Countdown Demonstration Test is scheduled to begin with
a call-to-stations at 8 a.m. April 6 and will culminate at 11
a.m. April 7 with a simulated engine cutoff.
STS-28 - COLUMBIA (OV 102) - OPF BAY 1
Power up testing planned this week includes check out of the
power reactant storage and distribution system, water spray
boilers, a functional test of the waste containment system and
leak and functional tests of the auxiliary power units. Retest
of the master events controller has been completed. Technicians
are preparing the orbiter's cavity for installation of the
forward reaction control system Wednesday night.
STS-33 - DISCOVERY (OV 103) - OPF BAY 2
Power up operations are scheduled today. Preparations for
activating the orbiter's hydraulic system are underway. The body
flap will be positioned to allow removal of the tail cone. The
payload bay door strongbacks were installed yesterday and the
payload bay doors are scheduled to be opened later this week.
The three main engines will be removed next week and engine
one will be sent back to the Rocketdyne plant in Canoga Park,
Calif. for analysis and repair of a crack in its main combustion
chamber. A new engine will be sent for Discovery's next flight.
STS-28 SOLID ROCKET BOOSTERS - RPSF
Buildup operations are continuing on the left and right aft
boosters. Technicians are scheduled to begin stacking segments
next week with the left aft booster in VAB high bay 1.
At Hangar AF, the STS-29 segments have been disassembled in
preparation for shipment back to Morton Thiokol in Utah for
refurbishment. The segments will go back by rail this week.
