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

After May 4th, Range has a WEEK-LONG stand down period, and CRS-17 would have to wait out that week until the 12th or 13th.

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.

If Dragon launches on 3 May, unberthing and splashdown will be roughly 31 May.

Weather a Concern for CRS-17 Launch

James Cawley
Posted May 2, 2019 at 12:44 pm


A prelaunch news conference for SpaceX's CRS-17 launch, targeted for Friday, May 3, at 3:11 a.m. EDT, was held at Kennedy Space Center in Florida on Thursday, May 2. Participants included, from left to right: Derrol Nail, NASA Communications; Kenny Todd, manager, International Space Station Operations and Integration, JSC; Hans Koenigsmann, VP, Build and Flight Reliability, SpaceX, and Will Ulrich, launch weather officer, U.S. Air Force 45th Space Wing.

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).

Follow along here on the blog and on NASA Television tomorrow beginning at 2:45 a.m. EDT for updates from the countdown.

SpaceX ground crews at Cape Canaveral are pressing ahead with a planned Falcon 9 launch attempt early Friday on a mission to resupply the International Space Station.

After the replacement overnight of a failed power distribution box on the space station, NASA and SpaceX teams gave the green light this morning to proceed with final launch preps, including the final installment of time-sensitive cargo into the Dragon supply ship.

The Falcon 9 and Dragon will be rotated vertical at Cape Canaveral's Complex 40 launch pad later this afternoon in preparation for the launch countdown.

Liftoff is timed for 3:11:33 a.m. EDT (0711:33 GMT) Friday, and the Falcon 9's first stage will target a landing on SpaceX's drone ship just off the coast of Cape Canaveral.

But forecasters predict iffy weather tonight, with a chance of rain showers from a tropical disturbance moving through the Bahamas.

There is a 60 percent probability that weather conditions will prevent launch Friday, primarily due to concerns with cumulus clouds, thick clouds, and precipitation in the Falcon 9's flight path.

Flight through precipitation is a concern for Falcon 9 launches with Dragon cargo capsules because the supply ship does not fly inside a payload fairing, and is exposed to the elements.

Weather conditions for a backup launch opportunity at 2:48 a.m. EDT (0648 GMT) Saturday look better.

Tracking suggests that Hollywood, OCISLY and GO Quest are returning to Port Canaveral.

Looks like we may be about get an announcement of a scrub due to weather.




Chris B - NSF‏ @NASASpaceflight 10 мин. назад

Uh oh. Really would be very low chance per weather forecast (mixed in with the single shot instantaneous window). ISS is now "fixed" per the MBSU.

So the word is there's bad weather off the coast and they could be just dodging it via repositioning.


Michael Baylor‏ @nextspaceflight 4 мин. назад

Unclear if they are repositioning the droneship for some reason (possibly weather), forgot @julia_bergeron's cookies, or if the launch attempt is off. Don't panic yet...


SpaceXFleet Updates‏ @SpaceXFleet 1 мин. назад

GO Quest has slowed quite a bit and has also changed trajectory so that they are no longer aligning with the port entrance channel. This continues to reinforce the suggestion that they are moving a bit to dodge some poor conditions.
