STATUS REPORT : STS-89-09
 
 
STS-89 Mission Control Center Status Report # 9
 
 

Following some on-orbit modifications today, Mir 24 crewmember Andy Thomas successfully completed a fit and leak check of the Soyuz Sokol spacesuit he carried to orbit, resolving the issue of which suit and Soyuz seat liner would remain on Mir during his planned four-month mission.

Thomas detached straps at the shoulders and groin of the suit which lengthened the suit sufficiently to allow a comfortable fit under both pressurized and non-pressurized conditions. He would wear the suit only in the event he were to return to Earth on board a Soyuz spacecraft.

Transfer activity continued to be the primary focus of the Mir 24 and Endeavour crews as the ten astronauts and cosmonauts continue to move science experiments, hardware and logistical supplies between their spacecraft. At day’s end, about 60 per cent of all of the planned transfer had been completed. While the transfer work continued, Thomas and former Mir resident Dave Wolf conducted handover briefings as Wolf acquaints Thomas with his new accommodations on board the Mir. Thomas will remain on Mir when Endeavour undocks on Thursday. He will return to Earth aboard the shuttle Discovery as part of the STS-91 crew in early June.

Meanwhile, flight controllers successfully uplinked a software patch to Endeavour which will bypass a suspect sensor in one of the shuttle’s reaction control system jets, restoring full leak detection capability for the ship’s jet thrusters. The sensor problem last night forced the Mir to assume temporary attitude control of the Shuttle-Mir complex, and kept Endeavour’s astronauts up beyond the start of their planned sleep period.

With everything proceeding smoothly aboard the two spacecraft, the shuttle crewmembers are expected to start an eight-hour sleep period at 8:48 p.m. Central time and will be awakened Tuesday at 4:48 a.m. to begin the sixth day of their mission.

The Endeavour-Mir complex is orbiting the Earth every 90 minutes at an altitude of about 216 nautical miles will all systems functioning in normal fashion.

The next STS-89 status report will be issued Tuesday morning at 6 a.m. Central time.
