KSC SPACE SHUTTLE PROCESSING REPORT - TUESDAY, OCT. 10, 1989
STS-34 - ATLANTIS (OV 104) - PAD 39-B
LAUNCH MINUS 2 DAYS
The pad was cleared this morning and loading of the power
reactant storage and distribution system with the liquid hydrogen
and liquid oxygen reactants is underway. This activity takes
about five hours. At the T-19 hour mark, at 4 p.m. today,
propellant loading activities will be complete and the countdown
will enter another planned built-in hold for 8 hours.
The countdown entered its first built-in hold at the T-27
hour mark, which lasted from midnight last night to 8 a.m. this
morning.
Last night, a glitch in the engine 2 low pressure fuel pump
discharge pressure sensor was experienced on channel B during
calibrations. Troubleshooting of the controller is underway. The
controller is an electronic package mounted on each engine and
controls all main engine components and operations.
The STS-34 five-member flight crew arrived at about 1:40
p.m. yesterday. Today, the flight crew canceled the T-38 flights
due to weather, but will perform fit checks of crew equipment
later today. Last night, Commander Don Williams and Pilot Mike
McCulley flew in the Shuttle Training Aircraft, satisfying
pre-flight requirements.
The weather forecast for launch time calls for scattered
clouds at 3,000-7,000 feet, winds out of the northeast at 10
knots, a temperature of 83 degrees and visibility of 7 miles.
Overall there is a 25 percent chance of violating launch weather
criteria because of crosswinds at the Shuttle Landing Facility,
rainshowers in the area and a cloud ceiling below 8,000 feet.
Forecasters expect the current rainy weather conditions to move
out of the area by Thursday.
Shuttle managers will meet here at KSC today for the routine
Launch minus two-day review to discuss the status and any open
issues.
Launch of STS-34 remains set for Thursday, October 12 at the
opening of a 10-minute window beginning at 1:29 p.m. EDT.
