Most elements of a major NASA event this week that laid out spaceflight plans for the coming decade were well received: a Moon base, a focus on less talk and more action, and working with industry to streamline regulations so increased innovation can propel the United States further into space.
However, one aspect of this event, named Ignition, has begun to run into serious turbulence. It involves NASA's attempt to navigate a difficult issue with no clear solution: finding a commercial replacement for the aging International Space Station.
During the Ignition event on Tuesday, NASA leaders had blunt words for the future of commercial activity in low-Earth orbit. Essentially, they are not confident in the viability of a commercial marketplace for humans there, and the agency's plan to work with private companies to develop independent space stations does not appear to be headed toward success. Plenty of people in the industry share these concerns, but NASA officials have not expressed them out loud before.
