PDU Replacement Preparation in Work Today

At NASA Kennedy Space Center’s Orbiter Processing Facility-3, technicians have reopened shuttle Discovery’s payload bay doors and will redeploy the right-hand radiator today. The doors are being reopened so the Centerline Latch Power Drive Unit or PDU, actuator can be replaced beginning Tuesday.

At NASA’s Johnson Space Center, STS-133 crew members will fly T-38 training aircraft to Edwards Air Force Base, Calif., to practice flight procedures.
