HOUSTON -- NASA wants to use the Space Shuttles primarily for constructing and supplying the space station, not for transporting ISS crews.
NASA is reviewing the 24 missions on the shuttle's schedule and considering changes necessary to meet President Bush's order to finish the station
and retire the shuttles by 2010, the officials told SPACE.com and Florida Today.
The change also would free seats for shuttle astronauts needed to perform added safety tasks, such as the heat shield inspections mandated after last
year's Columbia accident.
