Chris G - NSF @ChrisG_NSF 7:38 PM - May 1, 2020

Cool video of Dragon's approach to ISS!
#Demo2 #DM2 #SpaceX #NASA




7:39 PM - May 1, 2020

Crew will be in MANUAL control of Dragon at this point to validate that should auto-dock system ever fail, crew can control Dragon manually to docking.
#Demo2 #DM2 #SpaceX #NASA




7:39 PM - May 1, 2020

Final docking, however, will be done automatically by Dragon's computers.

NASA: Have built in VARIABLE mission duration to balance ISS and Crew-1 Dragon mission to follow.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon

Chris G - NSF @ChrisG_NSF 7:41 PM - May 1, 2020

Will also be testing Dragon's role as a safe haven or emergency evac craft for ISS crew on this mission.  Dragon will also bring supplies back from ISS.

Chris G - NSF @ChrisG_NSF 7:42 PM - May 1, 2020

Undocking to splashdown is about 24 hours.  Splashdown will be in the Atlantic Ocean off the coast of Florida.

Chris G - NSF @ChrisG_NSF 7:45 PM - May 1, 2020

Benji: We're getting appropriately nervous.  We're 26 days to launch.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


7:46 PM - May 1, 2020

Over 700 tests of the SuperDraco emergency escape system.  1000s of Draco thrusters.  TODAY will be the 27th test of Mk. 3 parachutes!

Chris G - NSF @ChrisG_NSF 7:51 PM - May 1, 2020

Will do Static Fire as usual.  Will also have a separate Crew Dry Dress where crew will get suited up, they go to the pad, get into Dragon, hatch will be closed, and they'll sim fueling and T0.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon

[tnt22]

Chris G - NSF @ChrisG_NSF 7:52 PM - May 1, 2020

Crew suits up 4hrs before launch.  Transport to pad is 3hrs before launch.  Get them in.  Get hatch closed.  Retract crew arm T-38 minutes and arm Crew Dragon abort system. T-35mins, begin fueling. T0: LIFTOFF.

Chris G - NSF @ChrisG_NSF 7:54 PM - May 1, 2020

Goal is to recover Dragon and have it on the ship and crew out 1hr after splashdown.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon

Chris G - NSF @ChrisG_NSF 7:56 PM - May 1, 2020

Decision for longer mission 6 months ago ().  About 210 days is what NASA thinks is max for Dragon for this mission.  That's the limiting factor in duration.  But Crew-1 schedule tracking is the driving factor.

Chris G - NSF @ChrisG_NSF 8:00 PM - May 1, 2020

NASA talking about how the SpaceX crew suits are full pressure suits and are leak-proof.

Chris G - NSF @ChrisG_NSF 8:04 PM - May 1, 2020

Banji: Touchscreens now give crew instant access to all info on craft.  A few manual controls for aborts as mandated for safety overrides.

Chris G - NSF @ChrisG_NSF 8:08 PM - May 1, 2020

Spacesuit question! Benji: Suits are really a subsystem of the vehicle. Designed to keep you safe while in the vehicle in case of loss of atmosphere. It's a 1-piece suit -- gloves and all!
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:09 PM - May 1, 2020

Benji: Suits will be used on launch, docking, undocking, and reentry and splashdown.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:10 PM - May 1, 2020

Bejji: Suits have "integrated comms systems ... water, food... everything needed to keep you safe."
#Demo2 #DM2 #SpaceX #NASA


8:11 PM - May 1, 2020

Benji: Outer part of suit is also capable of keeping the crew safe in case of fires.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:12 PM - May 1, 2020

Q: Suits correlation to Mars and Moon suits from SpaceX?
A: Benji... suits designed for use on Dragon today. But like all systems and everything we do, we deisgn based on knowledge and results and data to feed into future work.

Chris G - NSF @ChrisG_NSF 8:18 PM - May 1, 2020

Benji confirms, too, that Demo-2 will carry cargo up to the Station as well.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:21 PM - May 1, 2020

Minimum mission duration is 30 days.  Max is 119 days (because of the solar panels).
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:23 PM - May 1, 2020

Basically, Demo-2, with a late-May launch, would last until late-June (minimum) or late-September (maximum).  Decision point will revolve around Dragon performance and when next Dragon (Crew-1) mission is ready with a 4-person crew.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon

[tnt22]

Chris G - NSF @ChrisG_NSF 8:24 PM - May 1, 2020

Overall, Crew Dragon can reach Station within a couple of hours after launch or take up to 48 hours to reach Station based on launch day phasing to the Station.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:25 PM - May 1, 2020

All late-May in June launch opportunities for Demo-2 result in dockings around 19-24hrs after launch due to test flight requirements.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon


8:27 PM - May 1, 2020

Crew will enter a standard, pre-launch quarantine on 16 May for a 27 May launch.
#Demo2 #DM2 #SpaceX #NASA #CrewDragon

[tnt22]

Chris G - NSF @ChrisG_NSF 8:30 PM - May 1, 2020

Wow. SpaceX had to do extra tests on Crew Dragon to "make sure it could find the TDRS network" because of Starliner's mission clock timer error... not because Dragon exhibited any problems.
