snip/ Dunno why it took Edison so long to choose it for the light bulb.
Is it possible that he said "tungsten" but actually meant "titanium"? That would point back to the DM-1 use for the IFA static fire anomaly and make his sentence make more sense. That was indeed a titanium issue. Just thinking out loud.
And if they are just waiting on paperwork to be finished for the DM-2 flight, then that implies that these changes will be incorporated on later flights.

If there is a known issue they're worried about they would want it fixed for the first crewed flight.
Tungsten tubing is a thing, especially as a laminate or alloy. It has the highest melting point of any metal at 3410°C. Dunno why it took Edison so long to choose it for the light bulb.
Crew Dragon completes acoustic testing in Florida
NASA confirms SpaceX will become the first company in history to launch astronauts into orbitNASA has unambiguously confirmed that SpaceX – with its Crew Dragon spacecraft – will soon become the first private company in history to launch astronauts into orbit, both an unexpected twist from the usually tight-lipped space agency and a major upset for Boeing.
Quote from: CyndyC on 02/14/2020 03:14 pmCan the "hand-labor intensive" parachutes be reused? Also, does the need for additional testing after 10 already surprise anyone else? Looks to me like the SpaceX crew division and/or NASA just wants something for them to do while waiting on other paperwork to clear.I think I heard that the 10 tests already done had re-used the same parachutes. I believe that the crew missions with always have new chutes. NASA wants to make sure that brand new chutes from the factory work successfully. Also I think the final 2 test are more like system integration tests. The testing rig might be more like a real capsule.

I haven't seen reporting of this.

NASA PR has already walked this back, with a couple of strategic edits. We discussed that over in the DM-2 Mission thread.

There haven't been Health Stabilization posters in Mission Control since 2011. @Commercial_Crew is getting really close to flying people to orbit from the US again!
Seems like Demo-2 is not far off when you’re warning people not to get the astronauts sick.

If you want to keep it to technical details, then maybe this one needs a new name? I don't have time to read through the NSF SpaceX Missions section any more - there is simply too much going on over there these days (and that's a good thing!)
Koenigsmann says there are two more tests to go on Crew Dragon parachutes, testing “corner cases” in its operation.
.@SpaceX's Hans Koenigsmann says SpaceX performed a parachute test for Crew Dragon two days ago and it has two tests remaining.
Koenigsmann -- "almost done" with parachute tests for Crew Dragon. Two more to do. Turned something that was a concern into a successful test program.
