This undated artist illustration provided by Boeing shows the Crew Space Transportation (CST)-100. NASA has picked three aerospace companies to build small rocketships to take astronauts to the International Space Station. This is the third phase of NASA's efforts to get private space companies to take over the job of the now-retired space shuttle. The space agency is giving them more than $1.1 billion. Two of three ships are capsules like in the Apollo era and the third is a lifting body that is closer in design to the space shuttle. (AP Photo/Boeing)
