By New Scientist Space and Reuters (Image: NASA/Amanda Diller) NASA managers have cleared the space shuttle Endeavour for lift-off on 11 March on the first of three flights to deliver a huge Japanese research complex to the International Space Station. Blast-off from the Kennedy Space Center in Florida is scheduled for 0228 EST (0728 GMT). Barring last-minute delays, the flight would represent the quickest turn-around between shuttle missions since NASA resumed launches 2.5 years after the shuttle Columbia was destroyed on re-entry into the atmosphere in 2003. The shuttle Atlantis returned from a mission to deliver Europe’s Columbus research laboratory to the space station on 20 February. “We landed (Atlantis) nine days ago, which is just amazing to me,” said John Shannon, who took over last week as the shuttle programme manager. “The team has turned around and is ready to go.” The seven-man Endeavour crew includes two of NASA’s most experienced fliers, four rookies and Japan’s Takao Doi, who participated in a shuttle research mission in 1997. The shuttle is scheduled to spend two weeks at the space station to install a storage room for Japan’s Kibo laboratory complex and outfit the station’s Canadian-built robot arm with a mechanical hand. The primary portion of Kibo, which is a Japanese word for “hope,” is being prepared for launch in late May. The third segment, an outdoor porch for exposing experiments to space, will follow in 2009. During Endeavour’s flight, Europe’s new cargo ship, the Automated Transfer Vehicle, or ATV, will be loitering about 2 km (1.2 miles) from the station, waiting for its turn to berth. The debut flight of the European Space Agency’s unmanned spacecraft is scheduled for 2328 EST on 7 March (0428 GMT March 8). It will launch from Kourou, French Guiana. “Space is getting to be very busy,” Shannon said. Endeavour’s mission will also include a test of a heat-shield repair technique NASA wants to demonstrate before a servicing call to the Hubble Space Telescope in late August or early September. Without the space station to serve as a safe haven, a shuttle crew visiting the Hubble telescope has few options if their space ship should become too damaged to safely return to Earth. Columbia was destroyed, and its crew of seven killed, because its heat shield was damaged on lift-off. NASA is hoping to fly six shuttle missions this year, including the Hubble flight. The space agency needs to carry out 11 remaining space station construction missions by September 2010, when the shuttles are set for retirement.
