STS-93 -- Chandra X-ray Observatory
NOTE: Following last Thursday's Flight Readiness Review, Shuttle managers announced July 20 as the official launch date for STS-93.
Truck No. 1 on the Rotating Service Structure at Launch Pad 39B, has been repaired and is ready to support standard prelaunch activities. Last Friday, engineers completed a simulated countdown test for the payload's inertial upper stage and workers conducted routine voltage tests as well. Columbia's aft compartment closeouts are in work this week. Flight crew equipment early stow occurs tomorrow along with preparations for ordnance installation.
STS-93 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
STS-99 -- SHUTTLE RADAR TOPOGRAPHY MISSION (SRTM)NOTE: Integrated orbiter hydraulic testing concludes later this week. Endeavour's midbody close-outs are ongoing. Orbiter fluid servicing is also under way. Preparations are under way to receive the SRTM payload into the OPF and then install it into the orbiter's payload bay next Tuesday. The orbiter/payload interface verification test is slated for July 27.
STS-99 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
STS-103 -- 3rd HUBBLE SPACE TELESCOPE SERVICING MISSION (HST-3)NOTE: Replacement of Discovery's three fuel cells is complete. Over the weekend, workers drained residual propellant from the orbiter's right-hand orbital maneuvering system engine. Workers are scheduled to install a new right-hand orbital maneuvering engine this week. Removal of Discovery's robot arm from the payload bay begins tomorrow. Main propulsion system leak checks continue and ammonia system servicing begins this week.
STS-103 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
STS-101 -- 3rd INTERNATIONAL SPACE STATION FLIGHT - SPACEHAB DOUBLE MODULE/ICCNOTE: Last Friday, workers closed Atlantis' payload bay doors to accommodate optical payload bay fit-checks over the weekend. The payload bay doors will be opened again today. Managers plan to install the external airlock tomorrow.
Next week, workers will begin preparing Atlantis for a brief storage period in the Vehicle Assembly Building. Atlantis is scheduled to roll over to VAB high bay 2 on July 23 and remain there until it transfers to OPF bay 2 on Aug. 16. Atlantis is leaving OPF bay 3 to make room for orbiter Columbia's return from STS-93 and moves into OPF bay 2 following Endeavour's departure for the VAB.
