MEDIA ADVISORY: M11-089 SIX NASA ASTRONAUTS - INCLUDING D.C. NATIVE - AVAILABLE FOR INTERVIEWS
WASHINGTON -- The astronauts who flew aboard space shuttle Discovery's last flight will visit NASA Headquarters in Washington on Tuesday, May 10. They will give a presentation about their 13-day mission at 11 a.m. EDT and will be available for media interviews from 2 p.m. to 4 p.m. The STS-133 crew consists of Commander Steve Lindsey, Pilot Eric Boe, mission specialists Alvin Drew, Nicole Stott, Steve Bowen and Michael Barratt. Drew was born in the District of Columbia and graduated from the city's Gonzaga College High School. The crew will share mission highlights with agency employees, their families and reporters in the NASA Headquarters' James E. Webb Auditorium, located at 300 E Street SW. The presentation will air live on NASA Television. STS-133 was the last mission for the longest-serving veteran of NASA's space shuttle fleet. Since 1984, Discovery flew 39 missions, spent 365 days in space, orbited Earth 5,830 times and traveled 148,221,675 miles. Discovery and its crew delivered to the International Space Station the Permanent Multipurpose Module, or PMM, which was converted from the multipurpose logistics module Leonardo. The PMM can host experiments in fluid physics, materials science, biology, biotechnology and other areas. STS-133 also brought critical spare components and the Express Logistics Carrier 4 to the International Space Station. Robonaut 2, or R2, became the first human-like robot in space and a permanent resident of the station. The mission's two spacewalks assisted in outfitting the station and completed a variety of other tasks designed to upgrade station systems.
RELEASE: 11-145 SPACE SHUTTLE ENDEAVOUR TO LAUNCH NO EARLIER THAN MAY 16 News Conference Scheduled for May 9 CAPE CANAVERAL --
NASA managers have retargeted space shuttle Endeavour's launch to no earlier than Monday, May 16. After a meeting on Friday, they also extended the length of Endeavour's STS-134 mission to the International Space Station from 14 to 16 days. If Endeavour launches on May 16, liftoff would be at 8:56 a.m. EDT. At 3 p.m. on Monday, May 9, NASA Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach will hold a news conference at Kennedy Space Center in Florida to discuss the progress of repairs since Endeavour's launch postponement on April 29. The news conference will air live on NASA Television and the agency's website. Kennedy technicians are continuing work to resolve an issue in a heater circuit associated with Endeavour's hydraulic system that resulted in the launch postponement. Technicians determined the failure was inside an aft load control assembly, which is a switchbox in the shuttle's aft compartment, and possibly its associated electrical wiring. Although the root cause of the failure in the switchbox has not been found, technicians are replacing hardware that could have caused the problem. The faulty box was changed Wednesday, and a test of nine shuttle systems powered by the new box is under way. This weekend, technicians will install and check out new wiring that bypasses the suspect electrical wiring connecting the switchbox to the heaters. They also will run the heaters for up to 30 minutes to verify they are working properly and complete retesting of the other systems powered by the switchbox. The shuttle has three Auxiliary Power Units (APUs) that provide hydraulic power to steer the vehicle during ascent and entry. The hydrazine fuel lines on each APU have two heater circuits that prevent the fuel from freezing while the shuttle is in space. NASA launch commit criteria and flight rules require all APUs and heater circuits to be operational for launch. On Endeavour's first launch attempt, one of two heaters for APU-1's fuel line did not work. Engineers confirmed the circuit in the original switchbox that directed power to the heaters was shorted out. Launch attempts are available through May 26. May 21 is the only day a launch is not an option because it would lead to a May 23 docking with the space station. May 23 is when three of the space station's Expedition 27 crew members undock and return home in their Soyuz spacecraft. Managers reviewed the STS-134 mission timeline and determined the Endeavour crew can accomplish all objectives even with the departure of the three station crew members. To use the phone bridge for the May 9 news conference, reporters must have valid media credentials issued by a NASA center or for the STS-134 mission.
