(Very) unofficially, a source says they may switch to a thicker parachute design to compensate for issues discovered in the test. Although not ideal, this is a fairly normal part of spacecraft development.

If I remember correctly, Orion, Starliner, and Dragon all use the same parachute supplier - Airborne Systems. Is that still the case?

Update on NASA website today (removed, added)

SpaceX Demo-2 Update

NASA also is working with SpaceX to return human spaceflight launches to American soil. The company completed an uncrewed flight test, known as Demo-1, to the space station in March. SpaceX now is processing the same Crew Dragon spacecraft for an in-flight abort test. The company then will fly a flight test with a crew, known as Demo-2, to the station.

NASA’s Commercial Crew Program and SpaceX are expected to reevaluate reevaluating its target test dates in the next couple weeks.

Today the @NASA team left Houston early for @SpaceX to continue work prepping for our upcoming @Space_Station missions!

#SpaceX was wrapping both Dragon test articles in plastic tonight. Wonder if they have completed that part of the testing?

Lueders: we will learn from this test (the SpX anomaly).  Lots of data.
Still working on Demo-2 schedule.

SpaceX working to get new capsule for DM-2 ready by end of year, but anomaly investigation needs to be closed and any problems they find resolved before a new schedule can be set.

Is that the reassigned DM-2 vehicle (206) or the old DM-2, now IFA vehicle (205)?

Have not read about how the crew Dragon is made safe after it is hauled onto the recovery boat. In light of the latest mishap I am wondering how they safe all that hypergol propellant left in the dragon. I was trying to think if there ever was a situation where so much fuel was left on board while the crew was near it. Space shuttle must have had a lot left in it.

Does anyone know what the safeing procedure is for the crew dragon once it is hauled on-board?

Is memory correct that all NASA Crewed Dragons are new builds? If that is the case, something caused by the landing would be good in the short term.

I wonder if Dragon 2 flown in a cargo configuration will have the Super Draco system disabled and a minimal fuel load for the Dracos. Since for CRS-2 I thought SpaceX was planning on refurbing crew Dragon 2s and reconfiguring them for cargo.

Since the abort system is there, likely to remain intact. This way if the booster was to blow up the cargo could be saved. If your concern about reducing propellant load is to increase safety then that would mean it wasn't safe for astronauts.

Their renders are showing no superdracos, would imagine to save weight for Cargo.

Incorrect. No modification to propulsion.

From this morning's NASA ASAP meeting:

ne panel member notes that SpaceX has found some opportunities for "improving the design of the Dragon capsule." “We still don’t know whether those changes are directly related to the mishap”

ASAP mbr Susan Helms: SpX hasn't found root cause of Dragon anomaly, but have found some opportunities to improve Dragon design. Don't know if directly related to mishap, but fact they are adaptable and agile is positive aspect of their culture.

Do we think SpaceX will reuse Dragon 2's for the commercial astronaut missions to ISS, or will these missions also use brand new ones like the CCtCap?
