Last week NASA’s Aerospace Safety Advisory Panel (ASAP) issued its 2017 report [pdf], detailing the areas it has concerns for human safety in all of NASA’s programs. Not surprisingly, the report raised big issues about SpaceX, suggesting its manned launch schedule was questionable and that there were great risks using the Falcon 9 rocket as presently designed.
ASAP was especially concerned with the issues with the Falcon 9 COPV helium tanks and how they were connected with the September 2016 launchpad explosion, as well as SpaceX’s approach to fueling the rocket. Below is a screen capture of the report’s pertinent section on this.
The report complements NASA and SpaceX for looking at a new design for the COPV helium tanks, but also appears quite willing to force endless delays in order to make sure the issue here is completely understood, even though this is likely impossible for years more.
ASAP also raises once again its reservations about SpaceX’s method of fueling the Falcon 9, which would have them fill the tanks after the astronauts are on board so that the fuel can be kept cold and dense to maximize performance. This issue I find very silly. The present accepted approach is to fill the tanks, then board the astronauts. SpaceX wants to board the astronauts, then fill the tanks. Either way, the astronauts will be in a rocket with tons of volatile fuel and oxidizer. I really do not see why it makes that much of a difference, especially with SpaceX building a successful track record using its approach with each successful commercial launch. They did 18 last year alone.
Below the fold is a screen capture of the report’s entire summary, with some sections highlighted by me.
