At NASA Kennedy Space Center’s Orbiter Processing Facility-3, crews will test the centerline latch power drive unit, or PDU, actuator that was replaced yesterday on space shuttle Discovery. Then technicians will begin preparations to close the spacecraft’s payload bay doors one last time before the spacecraft is moved to the Vehicle Assembly Building next month to be joined to its external fuel tank and solid rocket boosters for launch. Liftoff is targeted for Nov. 1.
At NASA’s Johnson Space Center, the STS-133 astronauts will practice flight procedures in their T-38 training aircraft and perform various administrative duties.
