Could be some sort of hex associated with that leaky spacesuit they were hauling. This has the makings of a good horror movie! 😉
Dr Who: The waters of Mars.
“How to Drain Your Dragon.”
Most awful – and brilliant.
I do find it hard to fathom how an airtight spacecraft can admit water to the pressurize-tight area, except for the mentioned possibility of the pressure release valve.
What I’m wondering is if the issue is pressure gradient; the valve might be fine in keeping pressure in and preventing over-pressurization, but what if it doesn’t work right the other way; a sudden drop in pressure inside Dragon to below the external pressure results in flow the other way, and if submerged, that means water going in?
If so, the causal factor could be that the Dragon is warm inside after reentry (say, 85 degrees) and then enters cold sea water (the waters off California are cold, they’d be in the upper 50’s where Dragon splashed down) which cools the internal air via cooling the structure, thus creating a strong negative pressure gradient.
Reminds me of Jodie Foster putting an egg in a bottle.
Well, it’s good that they’re finding problems like this during unmanned missions.
But why did it take 11 hours to recover Dragon? In MA-7, Scott Carpenter landed 250 miles off target and was picked up in about three hours.
It helps to have the US Navy at your disposal.
Not July 21, no explosive bolts, and no one even on board.
I am sure the SpaceX crew will find and fix the problem.
Of that I have no doubt. And 100 times faster than NASA with fixes in place almost immediately. All I needed to know about Spacex was the day about 3 years ago when the had the on board computer abort a launch within 20 seconds to lift off. IIRC, SpaceX id’d the problem, fixed and still got the bird in the air before the launch window closed that same day. Can anyone here honestly say that NASA or the ULA could have handled a pad abort that quickly and still get a successful launch in?
I think the fastest ULA handled a pad abort was 24 hours.
I give SpaceX and Musk credit for flying, that’s hard.
However, they aren’t superhero’s it’s just 1960’s level engineering.
SpaceX also had some real amateur hour losses in the first couple.
