The United States Government Accountability Office (GAO) issued today an assessment of NASA’s Commercial Crew Program.

NASA has contracted with two companies — Boeing and SpaceX — to develop vehicles to transport astronauts to the International Space Station. Neither is expected to be ready until 2019.

Before any missions happen, the GAO reports, NASA will have to certify that both contractors’ vehicles are safe for human spaceflight.

Loss of crew metric

One way that NASA will assess safety is the loss of crew metric, which captures the probability of a crew member’s death or disability.

However, NASA doesn’t have a consistent approach for calculating this metric, so results can vary based on who within NASA is conducting the analysis.

The GAO has recommended that NASA clarify how it will assess loss of crew.
