It appears that SpaceX’s parachute testing for its Dragon manned capsule is finally satisfying the concerns of NASA and its safety panel, based on a Sept 17 NASA blog post.
In fact, SpaceX’s success has even forced NASA “to reevaluate its own [parachute] standards and certification processes.”
The article at the link also notes quite correctly NASA’s tendency to miss the forest for the trees, which is why it has forced SpaceX to do so much additional parachute testing, even though the company apparently had a solid understanding of its parachutes a long time ago.
[T]he space agency has been focused on parachutes and COPVs [the tank issues that caused the 2016 launchpad explosion] for years. This is primarily a result of NASA’s notoriously reactive approach to safety: SpaceX suffered two COPV-related Falcon 9 failures in 2015 and 2016 and has experienced an unknown number (likely 1-3) of anomalies during Crew Dragon parachute testing.
As a result, NASA has focused extensively on these two stand-out concerns. To an extent, this is reasonable – if you know things have a tendency to fail, you’re going to want to make sure that they don’t. However, prioritizing reactive safety measures at the cost of proactive safety would be a major risk, akin to getting in a car crash because you didn’t use a turn signal and then prioritizing turn signal use so much that you forget to look both ways before making turns. Sure, you will probably never get in the same crash, but you are raising the risk of new kinds of accidents if you overcorrect your attention distribution.
Either way, it increasingly appears that a manned Dragon mission might finally be getting close to launch.
