Space Shuttle Columbia - Information Note No. 1 2 February 2003 ESA INFO 2-2003. At about 14:00 GMT (15:00 Central European Time), Saturday 1 February 2003, the Space Shuttle Columbia was lost and seven NASA astronauts perished. They were Rick Husband, Mission Commander; William McCool, Pilot; Michael Anderson, Payload Commander; Kalpana Chawla, Mission Specialist; Laurel Clark, Mission Specialist; David Brown, Mission Specialist and the Israeli astronaut Ilan Ramon, Payload Specialist. The Director General, Antonio Rodotà, and the Director of Human Spaceflight Joerg Feustel-Buechl, have expressed ESA’s condolences to the NASA Administrator and other senior NASA officials and, through them, to the families of the astronauts.
Basic mission facts In a nominal Shuttle re-entry scenario, the re-entry phase starts about one hour before touch down and at some 8000 km from the landing site at the Kennedy Space Center (KSC) in Florida. At that point the Orbiter is at an altitude of about 170 km and is travelling at about 28000 km/h. The Orbiter is put into its correct orientation and reaction control system jets are fired to start the descent. About 5 minutes later, at an altitude of about 120 km, entry into the upper atmospheric begins with an automatic sequence monitored by an on-board control system. During this phase, between altitudes of 81 and 49 km, a communications blackout occurs, when radio signals cannot penetrate the layer of ionised gas particles surrounding the spacecraft. This phase lasts about 16 minutes. The whole re-entry phase can either be flown automatically or under crew control. The re-entry of Columbia on 1 February 2003 was not nominal. At about 14:00 GMT, communications with the Space Shuttle were lost. At this time, the Orbiter was flying over Texas, about 15 minutes from landing and at about 18 times the speed of sound. It was at an altitude of 63 km, about 1400 km from the landing site at KSC. Video films show the spacecraft following a constant track and apparently slowly disintegrating. Debris is being found over a large area of East Texas and Louisiana, and is being collected. The NASA Administrator, Mr Sean O’Keefe, has established an Interagency Mishap Investigation Board, which will provide an independent review of the events and activities that led up to the tragic loss of the seven astronauts on Space Shuttle Columbia. A statement has also been made by the Shuttle Programme Manager, Mr Ron Dittemore, addressing the possibility of damage being caused to the wing of Columbia during launch, but is not yet known if this has any bearing on the situation. All data is being safeguarded and, together with the retrieved debris, will be analysed to determine the cause of the accident.
Meanwhile the Shuttle fleet is grounded and, amongst other things, the flight of ESA astronaut Christer Fugelsang, planned for July 2003 on-board Space Shuttle Atlantis, is under review.
International Space Station (ISS) There are currently three crew on-board the ISS (Commander Kenneth Bowersox, NASA, and flight engineers Nikolai Budarin, RSA, and Donald Pettit, NASA). They were launched on 24 November 2002 on STS 113 (Endeavour) and were scheduled to return in mid-March 2003 on Shuttle Atlantis. A Russian Progress vehicle (9P) de-docked from the ISS as planned on 1 February, and a Soyuz flight with an unmanned Progress vehicle (10P) has been successfully launched on 2 February at 12:59 GMT, as planned, for a nominal refuel and logistics flight. There are sufficient supplies (food, water, fuel, etc..) on-board for several months of nominal activities. Soyuz 5S is on orbit as the station lifeboat and is planned to remain there until at least May 2003. Rosaviakosmos and NASA are currently assessing all necessary ISS and crew re-supply requirements for the coming months and will re-evaluate the manifest of the next flights of Progress (11P, planned for June 2003) and Soyuz (6S, planned for April 2003). The next crew exchange was planned to be on the March flight of Space Shuttle Atlantis. The next Soyuz flight, planned for 26 April 2003, is planned to be a taxi flight including ESA astronaut Pedro Duque. This flight is now under active review, but in the meantime Pedro Duque, as well as André Kuipers, who is scheduled to fly on Soyuz 7S in October 2003, are maintaining their training programme as planned.
The next several Shuttle missions to the ISS were planned to be a series of five truss/solar array assembly flights following an MPLM logistics flight, leading to the launch of Node 2 in February 2004. The effect of the Columbia tragedy on this sequence and schedule will be evaluated over the next weeks.
ESA payloads on board the mission The Space Shuttle Columbia carried the Spacehab Research Double Module with seven ESA payloads with a mass of 600 kg and representing approximately 25% of the payload in the Shuttle middeck and in Spacehab. All payloads performed well during the 16-day mission. However, for the following group of four biology and protein crystallisation research instruments, no scientific results will be available as no samples or electronic data can be provided to the Investigators for analysis:
