The forecast is good, but, just in case conditions change, Nasa has put its reserve landing strip in California on standby.The forecast is good, but, just in case conditions change, Nasa has put its reserve landing strip in California on standby.

The missile firing, which will take place over the Pacific Ocean, cannot be carried out until after Atlantis has landed for fear the ship might encounter debris on its high-speed descent.The missile firing, which will take place over the Pacific Ocean, cannot be carried out until after Atlantis has landed for fear the ship might encounter debris on its high-speed descent.
Nasa officials have reported that four small steering jets on Atlantis have failed, but they stressed these thrusters were not needed to help de-orbit the shuttle or control its glide through the atmosphere.Nasa officials have reported that four small steering jets on Atlantis have failed, but they stressed these thrusters were not needed to help de-orbit the shuttle or control its glide through the atmosphere.

Knowledge gained in the weightless conditions experienced on the platform are expected to aid the development of more advanced electronics, new alloys, novel drugs, and better crops, to name just a few examples.Knowledge gained in the weightless conditions experienced on the platform are expected to aid the development of more advanced electronics, new alloys, novel drugs, and better crops, to name just a few examples.
In addition to fitting Columbus, the Atlantis crew replaced an empty nitrogen tank on the station and retrieved a failed control-moment gyroscope that is one of four such mechanisms used to keep the ISS pointing in the right direction.In addition to fitting Columbus, the Atlantis crew replaced an empty nitrogen tank on the station and retrieved a failed control-moment gyroscope that is one of four such mechanisms used to keep the ISS pointing in the right direction.
Atlantis launches from the Kennedy Space Center A successful landing for the orbiter will be deeply satisfying for Nasa. It now feels it has the shuttle system working at optimum efficiency.Atlantis launches from the Kennedy Space Center A successful landing for the orbiter will be deeply satisfying for Nasa.

The fuel sensor problems experienced during recent launch campaigns seem to have been solved, and the shedding of shuttle tank insulation foam - the fatal flaw that downed Columbia and her crew in 2003 - has been minimised.The fuel sensor problems experienced during recent launch campaigns seem to have been solved, and the shedding of shuttle tank insulation foam - the fatal flaw that downed Columbia and her crew in 2003 - has been minimised.
Agency managers have expressed confidence that they can complete the construction of the ISS by the time the orbiter fleet is retired at the end of 2010 to make way for a new human launch system.Agency managers have expressed confidence that they can complete the construction of the ISS by the time the orbiter fleet is retired at the end of 2010 to make way for a new human launch system.

Because Atlantis will not be able to reach the space station if it gets into trouble, or is damaged, on its Hubble flight, the Endeavour orbiter will be made ready on the pad for a rescue mission in case it is needed.Because Atlantis will not be able to reach the space station if it gets into trouble, or is damaged, on its Hubble flight, the Endeavour orbiter will be made ready on the pad for a rescue mission in case it is needed.
Launch dates for the remaining seven flights in 2009/10 are under review. The crew of the space station is expected to rise from three to six in mid-2009.Launch dates for the remaining seven flights in 2009/10 are under review.
