OCO-3 will be placed on Japan's Kibo lab's exposed facility.

Weather:

Area of disturbed weather over Bahamas is encroaching to Space Coast. Will be near area overnight tonight. Higher than usual shower chance. Lower chance of lightning. Record moisture levels.

ChrisGebhardt · « **Reply #62 on:** 05/02/2019 03:25 pm »

Still a 60% NO GO chance for tonight (unchanged since yesterday). Back opportunity on Saturday, 4 May carries just a 30% NO GO chance (again, no change from yesterday).

Question: Crew launch chance this year? Land Zone status?

Hans: Will make program safer. Schedule will be determined by investigation and results. "Don't want to preclude schedule. Not great news, but hope we can recover. Multiple spacecraft in work."

Wanted to make sure evidence wasn't interfered with. Can access site, but can't get close to the Dragon stand yet.

03:11:33 EDT (0711.33 UTC) is precise launch time.

For landing the booster at sea this close to Port: Not as harsh on teams. Easy for teams when booster lands closer to shore. Procedure and protocol same as way out at sea landings. No change based on proximity to Port Canaveral.

Stephen Clark: Walk us through what happens during SuperDraco activation and role of COPVs?

Pressurize system, open and close valves. You do NOT pressurize COPVs at that time. The COPVs are different than the ones on Falcon 9. Different material and form. "Fairly confident the COPVs are going to be fine."

Vibroacoustic testing: Didn't get that point in this test.

Hans reiterates that the system they're looking at for Crew Dragon anomaly is not a system that's on Cargo Dragon.

ChrisGebhardt · « **Reply #68 on:** 05/02/2019 03:43 pm »

Good question from Irene Klotz: were any SuperDraco tests conducted on systems that had been in the water before? Hans wasn't sure. Possibly.

ChrisGebhardt · « **Reply #69 on:** 05/02/2019 03:47 pm »

May 3rd and 4th are available for launch. After that, Range has a week-long stand down period where no launches can happen. CRS-17 would have to wait until 12th or 13th is not off the ground by the 4th.

ChrisGebhardt · « **Reply #70 on:** 05/02/2019 03:52 pm »

New Falcon 9 booster on CRS-17. It's luck of the draw. No thinking change on NASA's part for using flight-proven cores.

Hans talks about need to fly new boosters to replenish the Falcon 9 fleet.

ChrisGebhardt · « **Reply #71 on:** 05/02/2019 03:53 pm »

Will try to bring the MBSU that failure back down to see what happened on a later flight.

ChrisGebhardt · « **Reply #72 on:** 05/02/2019 03:54 pm »

Dragon coming back around 31 May for launch on 3 May. Once there's a launch and berthing, then NASA (re)evaluates when Dragon's departure date will be.

Next SpaceX launch is mid-May.

Hans liked Chris G's question about why a "new booster" for CRS-17 and a paradigm shifting in thinking vs "flight proven" in his query...

Weather a Concern for CRS-17 Launch

James Cawley Posted on May 2, 2019

Following this morning’s prelaunch news conference at Kennedy Space Center in Florida, SpaceX is continuing to target Friday, May 3, for an instantaneous launch of its 17th Commercial Resupply Services Mission at 3:11 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station.

One factor to watch will be the weather.

“Normally I’m not the bearer of bad news but I kind of feel like I am today,” said Will Ulrich, a launch weather officer with the U.S. Air Force 45th Space Wing. “We’ve been monitoring an area of disturbed weather over the Bahamas for the past few days, and that area of disturbed weather is encroaching upon the Space Coast.”

The launch day forecast calls for a 40 percent chance of favorable weather for liftoff of the SpaceX Dragon spacecraft aboard the company’s Falcon 9 rocket. That prediction includes winds between 15-20 mph. The primary weather concerns are cumulus and thick cloud rule, and flight through precipitation.

The Dragon spacecraft will deliver supplies including critical materials to support dozens of the more than 250 science and research investigations that will occur during Expeditions 59 and 60. The spacecraft’s unpressurized trunk will transport NASA’s Orbiting Carbon Observatory 3 (OCO-3) and Space Test Program-Houston 6 (STP-H6).

Here’s the forecast at 40% GO:

Quote

Launch day probability of violating launch weather constraints: 60%
Primary concern(s): Cumulus and Thick Cloud Layer Rules, Flight Through Precipitation

Delay day probability of violating launch weather constraints: 30%
Primary concern(s): Cumulus and Thick Cloud Layer Rules, Flight Through Precipitation

A prelaunch news conference for SpaceX’s 17th Commercial Resupply Services (CRS-17) mission to the International Space Station for NASA is held at the agency’s Kennedy Space Center in Florida on May 2, 2019. From left, are Derrol Nail, NASA Communications moderator; Kenny Todd, Manager, International Space Station Operations and Integration at NASA’s Johnson Space Center in Houston; Hans Koenigsmann, VP, Build and Flight Reliability with SpaceX; and Will Ulrich, 45th launch weather officer with the U.S. Air Force. The SpaceX Falcon 9 rocket and Dragon cargo module are scheduled to launch no earlier than May 3, 2019, from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.
