Here's the weather forecast for SpaceX's 2nd astronaut launch attempt on Saturday

Quote

SpaceX called off the launch of its Crew Dragon spacecraft from Kennedy Space Center in Florida about 17 minutes before the planned liftoff due to unfavorable weather conditions. The crewed test flight, called Demo-2, is now slated for a second launch attempt on Saturday (May 30), with a backup launch window on Sunday (May 31). The Saturday launch attempt would be at 3:22 p.m. EDT (1922 GMT), while the Sunday attempt would lift off at 3 p.m. EDT (1900 GMT).

In its latest launch weather forecast, issued today at 8:30 a.m. EDT (1400 GMT), the U.S. Air Force's 45th Space Wing predicted a 60% chance of unfavorable weather conditions that would prevent SpaceX from launching the Demo-2 mission on both Saturday and Sunday.

Their forecast cites precipitation, anvil clouds and cumulus clouds as "primary concerns" on Saturday, and adds thick clouds to the list of possible weather violations on Sunday.

The 60% chance of a weather violation is slightly worse than the weather forecast SpaceX and NASA were facing with the first launch attempt. The 45th Space Wing had predicted a 50% chance of bad launch weather on Wednesday, which was much better than the 70% chance it had predicted just a few days before the planned launch.

I think the next window is Sunday, the 31st if it gets scrubbed Saturday?

NASAâ€™s SpaceX Demo-2: Countdown Update

NASA by Anna Heiney

Quote

The countdown continues to go well for todayâ€™s planned 3:22 p.m. EDT launch of NASAâ€™s SpaceX Demo-2 flight test to the International Space Station. At Kennedy Space Centerâ€™s Launch Complex 39A, the SpaceX Falcon 9 rocket is powered on and the launch team is pressurizing gaseous storage vessels onboard. Meanwhile, the Crew Dragon spacecraft is being prepared for NASA astronauts Douglas Hurley and Robert Behnken to board later in the countdown. Weather remains the big question for today; the chance of favorable conditions at launch time remains 50%.

Weâ€™re standing by to see the crew leave the suit room in Kennedyâ€™s Neil Armstrong Operations and Checkout Building and wave to their family, friends and support team members before the ride to the launch pad.

50%?

Why are they doing "early" PM launch times? Seems like Apollo missions launch times were A.M. Maybe that was Apollo 11.

catfish1957 · « **Reply #13 on:** May 30, 2020, 04:55:55 pm »

Lot of convection east and west of the launch site. And a lot more than before the scrubbed launch mid week. I am not too optimistic.

But who knows.... Maybe we'll get lucky this time.

The launch time is dictated by the trajectory path required for the mission. In this case, for docking with ISS.

ForecastDiscussion:A low-pressurearea is moving into the Canadian Maritimes while trailing a frontal boundary along the Atlantic Coast States. This boundary willbring pre-frontal weather into the Atlantic and nudgethe subtropical ridge axis overthe Spaceport. This will impede the inland progression of the east coast sea breezeand, coupled with the westerlysteering flow, push inland convection towards the Space Coast. The morning sounding shows instability in the moderate range, meaning the convection may hold off until after T-0. The primary concerns are flight through precipitation, as well as the anvil and cumulus cloud rules fromthe convection.On Sunday, the late season frontal boundary will provide some added cloudiness over the Spaceportearly, but will likely push just south of the area by T-0. The primary weather concerns for launch are flight through precipitation, the thick cloud layer rule, and the cumulus cloud rule, associated withthefrontal boundary.Monday and Tuesday will bring a noticeable change to Central Florida, with limited convection and strong onshore winds. The primary concerns for launch are cumulus clouds and flight through precipitation with coastal showers.

That's a more optimistic look than my outlook, and they do have the direct met data. OTOH, I have lived my entire life near the Gulf Coast, and know how weather can change rapidly with a few cumulus clouds and unabated summer heat.

Fingers crossed!!!!!

12:58 pm: NASA chief Bridenstine says thunderstorms may clear before launch

NASA administrator Jim Bridenstine gave an update on the weather forecast, which he said shows thunderstorms headed to the launch area. Bridenstine said that, with launch set for 3:22 p.m., the severe weather could clear by 3 p.m. at the earliest and 3:30 p.m. at the latest. He added that the weather â€œtrend is better today than it was on Wednesday.â€

12:42 pm: Bob Behnken and Doug Hurley get into the spacecraft

NASA astronauts Bob Behnken and Doug Hurley took an elevator up to the top of the tower at launchpad 39A at Kennedy Space Center. The astronauts walked out to the end of the crew access arm, 255 feet above the ground, and then got into the Crew Dragon spacecraft, where they got strapped in to their seats.

1:47 p.m.: Weather not cooperating

The launch has not been scrubbed, but there is a no-go because of weather right now. NASA and Space X are waiting to see if conditions improve.
