MISSION STATUS REPORT #18 -- FLIGHT DAY 9 11:30 a.m. CDT -- Thursday, June 13, 1991 Columbia's crew was awakened to The Nylons' "Chain Gang" an hour and a half late following a restless night of interuptions to switch cooling loops on the Research Animal Holding Facility and move experiment samples from one freezer to the other. Following wakeup, the crew busily conducted the final hours of work in the Spacelab collecting urine, blood and saliva samples along with echocardiograph and pulmonary function data. The last Getaway Special canister at the back of the payload bay was opened. This payload consists of six experiments performing various tests concerned with aqueous phases, growing organic crystals and thin films, metallic materials, observing cosmic ray interactions and measuring cosmic radiation on the genetic and chromosomal structure of yeast. The orbiter crew also was busy this morning putting Columbia's systems through their paces to verify readiness to support tomorrow's deorbit, entry and landing at Edwards AFB, CA. Columbia continues to perform very well as the crew prepares to stow equipment in the cabin and Spacelab module for tomorrow's return. Weather predictions at Edwards for the landing appear to be favorable with winds out of the southwest at 15 knots gusting to 20. With landing scheduled for runway 22, a direct headwind on the orbiter presents no problem for landing. The touchdown time is set for approximately 10:39 a.m. CDT. MCC STATUS REPORT #19 --- FLIGHT DAY 10 5:00 a.m. --- Friday, June 14, 1991 Planning shift flight controllers spent their overnight shift monitoring systems and reviewing plans for the final steps in the Spacelab module and orbiter deactivations procedures in addition to plans for deorbiting and landing. Columbia's orbiter crew, commander Bryan O'Connor, pilot Sid Gutierrez, and mission specialist Tammy Jernigan, were awakened to "What a Wonderful World" by Louis Armstrong at 2:44 a.m. CDT while the remainder of the crew slept until 3:44 a.m. Today the crew will power down the equipment in the Spacelab, stow the KU-band antenna, and close the payload bay doors in preparation for landing. The port payload bay door closing is scheduled to occur about 6:24 a.m. CDT. About five minutes before the port payload bay door closing, Mission Specialist 1 Jim Bagian will reenter the Spacelab module and put the final urine samples in the lab's freezer L9I which overnight was empty. All other urine, blood and saliva samples are stowed in the lab's other freezer unit L8I. Bagian then will videotape the payload bay door closing to document how the door closing occurs with the loose environmental seal on the orbiter's aft bulkhead. The closing of the starboard payload bay door is scheduled for 7:01 a.m. CDT. Columbia's deorbit burn is scheduled for 9:37 a.m. CDT. The deorbit burn occurs when the vehicle's engines fire about three minutes. That slows the spacecraft which allows it to begin its fall toward the Earth's atmosphere. Landing is expected to occur at 10:39 a.m. CDT at Edwards Air Force Base in California on the base's concrete runway 22. Weather predictions at Edwards for the landing continue to be favorable with winds out of the southwest at 12 knots gusting to 20 knots. Three of Columbia's crew members, O'Connor, Gutierrez and Jernigan, will return to Houston about 10 hours after landing. The remainder of the crew - Bagian, Seddon, Gaffney and Hughes- Fulford - will stay at Edwards for a week of continued experiments to learn more about how the human body readapts to gravity after being in a weightless environment for nine days. STS-40 Postlanding Report 6/14/91 The seven-member STS-40 crew glided to a landing aboard Columbia this morning at Edwards Air Force Base. Columbia's reentry and landing went nominally and weather at Edwards was exceptionally crisp and clear as Columbia landed right on time at 11:39 am EDT on concrete runway 22. Even though Columbia's mission is finished and commander Bryan O'Connor, pilot Sid Gutierrez and mission specialist Tammy Jernigan have completed their mission tasks, the other crewmembers have another seven days of life science experiments and procedures awaiting them. Mission specialists Rhea Seddon and Jim Bagian and payload specialists Millie Hughes-Fulford and Drew Gaffney will remain at Dryden Flight Research Facility in the medical science facility for a week's worth of experiments which mirror those performed in the Spacelab. The post-landing life science investigations are as important to an understanding of the effects of weightlessness as were the on-orbit investigations. O'Connor, Gutierrez and Jernigan are scheduled to depart for Houston tonight. Columbia will be ferried back to Kennedy Space Center next week. In yesterday's final mission science summary briefing, mission experiment director Dr. Ron White said Columbia's crew had accomplished nearly 100 percent of the required experiments and also had gathered data from additional crew subjects for several of the investigations. The few experiments whose data requirements were not completely met are presently scheduled to refly on SLS-2. The science data has been superb, according to White, and will form an exceptionally solid foundation for the SLS-2 mission, as well as adding to the database required for space station studies. -- Eric Behr, Illinois State University, Mathematics Department Internet: ejbehr@rs6000.cmp.ilstu.edu Bitnet: ebehr@ilstu
