for me orbital space plane(軌道航天飛機(jī))，which would be designed to transport a crew of four
to and from the International Space Station．
Although it includes few specifics，the plan states the orbiter(軌道航天飛機(jī))will be safer
cheaper and require less preparation time than the shuttle．It would be able to transport four crew
members by 2012--though it would be available for rescue missions by 2010.NASA says the
craft should be able to transport injured or ill space station crew members to“definitive(決定性
的)medical care” within 24 hours．
The release of the requirements showed NASA remains focused on the long-term priorities
of space exploration，even as questions exist concerning the loss of Columbia and its
seven．member crew on February l，2003．．
Expels at Marshall Space Flight Center in Huntsville，Alabama，have been working for
years on a successor to the shuttle．The project，known as the Space Launch Initiative(倡議)，
was divided last year into two parts----one focusing on a future launch vehicle，the other on a
space station orbiter．The orbiter is expected to be ready sooner．
The program’s managers say NASA officials have told them not to alter Space Launch
Initiative in light of the Columbia disaster．
U．S．President George W：Bush asked Congress for about US$1 billion for Space Launch
Initiative in 2004，funds that would be almost equally split between the Orbital Space Plane and
Next Generation Launch Technology．
41 NASA plans to design the new space craft to
A control the International Space Station．
B carry astronauts to the International Space Station．
C transport equipment to the International Space Station
D train astronauts in space flights．
42 Besides its main mission．the orbiter would also be used as
A a medical research center．
