After spending the last few years complaining about certain specific issues with the manned capsule efforts of SpaceX and Boeing, NASA’s safety panel this past weekend released its annual 2018 report. (You can download the report here [pdf].) Its position now on those certain specific issues can now be summarized as follows:
They make no mention of the parachute issues that forced Boeing to do numerous extra tests, causing probably a year delay in the program, though Boeing has had decades of experience with capsule parachutes and the entire American aerospace industry has never had a parachute failure.
The panel also admits that their concerns about SpaceX’s rocket fueling procedures is really not an issue.
The NESC [NASA Engineering and Safety Center] has independently studied the load and go procedure and provided a thorough report that identifies the hazards and available controls. Based on the NESC report, the CCP [Commercial Crew Program] has decided that the load and go concept is viable if subsequent analysis is adequate and if verifiable controls are identified and implemented for all the credible hazard causes that could potentially result in an emergency situation or worse.
As Emily Litela said, “Never mind!” Their concerns were never credible, as it really doesn’t matter if you fuel the rocket before or after the astronauts board, because in either case they are there when a lot of fuel is present. All the panel did was delay the first Dragon launch by at least a year by pushing this issue.
The panel is still holding onto its concerns about the installation blankets (COPV) used in SpaceX’s internal helium tanks, the location of the problem that caused the September 2016 launchpad explosion. Despite SpaceX’s apparent fixing of this problem, with 40 successful launches since that failure, they are listing further vague requirements:
