Camille: 4,500lbs of research supplies and science investigations. Dragon will return 1,500lbs of science samples at end of CRS-11.

Mike: Welcome to Central Florida's convective season. It will help the fires, but it will make afternoon launches "sporty" for next three months.

Mike: Models suggest guidance flow will switch tomorrow. Thunderstorms likely tomorrow, but guidance patterns should shift the T-storms inland enough to get off tomorrow at 17:55L.

Mike: Only 84 F at launch (as a local, I can attest that that's darn near *cool* for this time of year). Anvil cloud rule might give options to get off, but will have to monitor.

Mike: If 24hr delay, weather guidance suggestions pattern like today (it's raining right now at KSC).

Irene asking about MDM failure.

A: Ideas of what happened. Most likely, this'll come back on CRS-11.

Irene asking about monetary reason to reuse Dragon.

Kirk: Reuse very very important. This isn't new. Shuttles flew many time. Contract is fix-priced, and things are "equitable".

Marcia: What did you do to refurb the Dragon. How much is original? Will next Dragon be reused version?

Hans: Majority of Dragon (hull) is same. When Dragon came back, we inspected it against its qualification specs, and we made sure all items had enough "life" for this mission. Same idea to what we do with the booster. Results shared with NASA and reviewed together. Some cases (FEW), there were components that needed to be swapped out.

MAJORITY of this Dragon has been in space.

Next Dragon is new from what Hans remembers.

Some batteries (because of sea water intrusion) were replaced. Thrusters are the same to CRS-4.

Hans: Heat shield is new.

ChrisGebhardt · « **Reply #49 on:** 05/31/2017 08:23 PM »

Most plumbing, avionics are from previous flights, too.

Jason asking if fairings are coming back anytime soon.

ChrisGebhardt · « **Reply #51 on:** 05/31/2017 08:25 PM »

Fairings from last flights did land, but were damaged. Still work to be done to get fairings back in condition where they can be reused.

Possibility of future CRS missions flying on a reused F9?

Kirk (NASA): Working on it now.

ChrisGebhardt · « **Reply #53 on:** 05/31/2017 08:30 PM »

Production timeline of Dragon now that they're being reused?

One more capsule being built. Might be able to do all future cargo flights with reused capsules. But that might not be what happens. Hans says he isn't the best person to answer that question.

Me: Inmarsat had abbreviated LOX fueling, started at 35mins instead of 45mins. Will CRS-11 use 35 or 45 min LOX fueling?

Inmarsat had hardware to allow for fast fueling. CRS-11 and Bulgaria boosters don't have that tech because of when they were built. They will both use standard LOX load starting at T-45mins.

Me: What if launch weather is OK but landing weather isn't? Will you launch and just expend booster?

A: Launch weather covers landing weather. Launch weather drives availability. If we're good to launch, we're good to land.

SLC-40 progress?

A: Late summer/early fall return to operation on SLC-40. NO decision on which mission goes first.

ChrisGebhardt · « **Reply #56 on:** 05/31/2017 08:40 PM »

17:55:51 EDT for exact in-plane launch.
