Internally, NASA believes Boeing ahead of SpaceX in commercial crew

One of the biggest rivalries in the modern aerospace industry is between Boeing and SpaceX. Despite their radically different cultures, the aerospace giant and the smaller upstart compete for many different kinds of contracts, and perhaps nowhere has the competition been more keen than for NASA funds.

In 2014, both Boeing and SpaceX received multibillion awards (Boeing asked for, and got, 50 percent more funding for the same task) to finalize development of spacecraft to carry astronauts to the International Space Station as part of the commercial crew program. Since then, both companies have been locked in a race to the launchpad, not just to free NASA from its reliance on Russia to reach space but also for the considerable esteem that will accompany becoming the first private company in the world to fly humans into orbit.

A narrow margin

Although both Boeing and SpaceX have established various launch dates—first in 2017, and now slipped to 2018 and 2019—NASA hasn’t publicly tipped its hand on which company is actually ahead in the race. Now, however, a new report from the US Government Accountability Office has provided a window into NASA’s internal thinking on commercial crew launch dates.

The data is several months old, coming from an April 2018 analysis. But it’s insightful all the same. The report shows when NASA believes Boeing and SpaceX will each have completed a single non-crewed test flight, a test flight with crew, and then undergo a certification process to become ready for operational flights. This is known as the “certification milestone.”

This electric double-decker bus from Alexander Dennis and Proterra will be put into service with Foothills Transit by 2019.

Alexander Dennis

On Thursday, a Los Angeles county transit agency purchased the first all-electric double-decker bus in North America. The bus will be made with batteries from electric bus designer Proterra, and the carriage of the bus will be designed by Alexander Dennis, the company that supplies double-decker buses in London, Hong Kong, Auckland, Singapore, Toronto, Ottawa, Seattle, and Mexico City.
