NASA Needs Backup Plan To Maintain U.S. Presence At Space Station, Watchdog Says [npr.org]
A government watchdog agency wants NASA to come up with a contingency plan for getting American astronauts to the International Space Station.
The recommendation is one of the major takeaways in a 47-page report from the Government Accountability Office [gao.gov] on what is known as the Commercial Crew Program.
[...] Under the Commercial Crew Program, NASA chose SpaceX and Boeing to develop the next generation of crew capsules to take the place of the shuttle. The two companies are competing to see which one will be the first private company to launch American astronauts into space.
The GAO's report acknowledges that SpaceX and Boeing have made "progress developing their crew transportation systems," but that "both contractors have further delayed the certification milestone to early 2019." The companies had initially been required to prove to NASA that their spacecraft would meet the agency's requirements for human space flight by 2017.
