Yep, “mini” chocolate cakes for my 50th birthday, because somebody, somewhere, loves me. Thank you @Astro_Megan for making it happen!

Preps for SpaceX fleet recovery:

Join NSF's Julia Bergeron (@Julia_bergeron) for an overview of the recent SpaceX Fleet recovery operations and the preparations for the recovery of the Demo-2 crew during next week's Dragon Endeavour splashdown.

.@AstroBehnken and @Astro_Doug are scheduled to return to 🌎 on Sunday. Over the weekend, robotics flight controllers on the ground used #Dextre to inspect @SpaceX Crew Dragon to make sure it is good to go.

Shame they used an old image ...

Good chat with Garrett Reisman (@astro_g_dogg) on Demo-2 return:

– Heat shield designed for lunar return, so Bob and Doug have extra margin

– Determine amount of shield used by drilling core samples

– Recovery ship more equipped than folks realize

Bob and Doug reported their suit check outs went well with no issues. MCC-H reported Hawthorne controllers heard the report and that the crew had permission to come home

Panelists

Bridenstine mentions weather concerns.
Stich reports "spacecraft is very healthy." FRR go for undock / landing. Landing sites graphic. Daytona landing site added.

FutureSpaceTourist · « **Reply #89 on:** 07/29/2020 07:41 pm »

If they can’t undock Saturday for landing Sunday, due to weather, then next opportunity is to undock Monday.

Plenty of opportunities in August to return, there’s no hurry.

Stich: After splashdown they'll review the vehicle's data and begin processing the capsule, getting it ready to be launched again for the Crew-2 mission in spring.

Reed shows off a video SpaceX made about the Demo-2 mission thus far.

Here's a clip we hadn't seen before, from inside the Crew Dragon Endeavour capsule during liftoff:

Montalbano: out of review with no actions; standard work.
“Benji” Reed: mentions 45 years since last US human splashdown; shows mission summary video. mentions successful FRR and weather evaluation. Shows infographic.

sdsds · « **Reply #92 on:** 07/29/2020 07:53 pm »

Benji: two fastboats arrive at splashdown first; then main recovery vessel. Within 4 hours back to land either quickly by helo or by boat. Reiterates it's a test mission; extra attention.
Shows Crew-1 vehicle currently in Hawthorne; shipping out in August.
Shows Crew-1 crewmembers.

Grush from The Verge: q about leeway, how long before undock can departure be delayed; similarly for deorbit.
Stich: quite a bit of margin. mentions 6 hours before undock and 2.5 hours before undock as key decision points. mentions freezers as late load items. Mentions 15-17 hours after undock as possible pause points for de-orbit burn decision. 3 days of consumables after undock.

sdsds · « **Reply #94 on:** 07/29/2020 08:04 pm »

Brinkman from UPI: q about habitability test
Stich: brought over added crew and did "life in the day of dragon" exersize. Learned about package and stow of items needed during flight.
Stephen Clark from spaceflight: q for benji about what happens to spacecraft after recovery; refurb and mods.
Benji: refurb crew onboard recovery vessel safing vehicle and getting data off. "awesome" dragon facility at cape for preps and refurb. some things will be replaced; of course new trunk for each flight. in this case upgraded solar arrays on upcoming flight. should have dragon ready in just a few months; plenty of margin for 6 months reflights.
Reuters for Reed: what led to decision to reuse crew dragon for crew-2?
Benji confirms contract called for new vehicles but years of "proving awesomeness of reuse" led to change; safety and reliability perspective; reality is the dragon 2 line is designed for at least 5 reuses and possibly more; safer and more reliable in some ways. Mentions dragon 1 almost half were "flight proven" vehicles.

Tariq Malik: q on weather constraints.
Stich: Wind limits. Wave limits (re: heat shield structural limit). Rain. Lightning. Helicopter limits. Set up for constraints met at two sites before undock. Todd and Montalbano okay with delays.
Eric Berger: q about NASA becoming more comfortable with reuse both for falcon and dragon.
Bridenstine: Sustainability ; allowing private company innovation; applications for moon and mars.
Reddit group q for Benji: deorbit burn and trunk
Benji: fundamentally big difference on trunk jettison. No good detail to provide right now.
ABC News: q re: 3 days of supplies what limits
Stich: O2, LiOH, food, water. Could stretch the limits. Plenty of power, prop, O2 for crew.

sdsds · « **Reply #96 on:** 07/29/2020 08:16 pm »

Q: assets on standby?
Stich: detachment 3 from DoD. C17 at Hickham. Hawaii and Charleston for off-nominal recoveries. Go Searcher, Go Navigator as prime vehicles for recovery. SpaceX helos.
Harwood CBS: winds up to 10, specifics on wave height? changes for crew1?
Benji: info online. wave height and period. > 7 deg wave slope. Integrated problem; some absolute individual thresholds but assessing readiness is combo of factors. Greater capability for crew-1 vehicle will increase landing opportunities. Specifics on nasa.gov.
Marsha Dunn: numbers ships, helos, people staged?
Benji: 2 primary recovery vessels. Helos can xfer support personnel between locations. Fastboats. Over 40 people on the boat. 5 or so contractors driving the boat, then roughly 20 SpaceX and 20 NASA, including medics etc.

sdsds · « **Reply #97 on:** 07/29/2020 08:19 pm »

Marcia Smith spacepolicyonline: refurb schedule
Stich: test flight. more instrumentation. collect data. jointly analyze.
Dave Mosier businessinsider: on orbit vehicle inspection results?
Stich: weekend inspection with ssrms as with all undocking vehicles including russian. results very favorable. no areas of concern on vehicle. safe for return. do the same thing for subsequent flights. got data needed. good res photos.

Q-still planning 6 wks to complete certification? Accelerate process since mission going so well esp if landing delayed?
Stitch: test flight. Need to check all the data. Don't envision accelerating the process.

Unfortunate that the first time I get to ask a question I get a non-answer
