Besides astronauts, what else is NASA going to bring to Space Station?

NASA plans to retire the space shuttle in 2010 so it’s been looking for private companies that can bring supplies and maybe astronauts to the International Space Station. Back in 2006, NASA picked two companies to work with. But one—Rocket Plane Kistler—failed to raise enough private funding. NASA canceled that agreement and it has now selected Orbital Sciences Corporation as replacement. The company already built small rockets to carry commercial and military satellites to orbit, now it plans to build a bigger rocket called the Taurus 2. NASA is continuing to back a start-up company called Space X. It has tried two launches. The first rocket caught fire, the second made it to space but did not achieve orbit.
