Weather Forecast Remains 80 Percent ‘Go’; Prelaunch Briefing Set for Thursday

Anna Heiney Posted on February 27, 2019

Three days remain until the planned liftoff of a SpaceX Crew Dragon spacecraft on the company’s Falcon 9 rocket—the first launch of a commercially built and operated American spacecraft and space system designed for humans. Liftoff is targeted for 2:49 a.m. EST on Saturday, March 2, from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The Demo-1 mission to the International Space Station serves as an end-to-end test of the system’s capabilities.

The launch weather forecast continues to look promising; meteorologists with the U.S. Air Force 45th Space Wing predict an 80 percent chance of favorable weather at launch time. Thick clouds or cumulus clouds that would violate launch requirements are the primary weather concerns.

NASA will host a prelaunch briefing at Kennedy at 4 p.m. EST on Thursday, Feb. 28. The briefing will be broadcast live on NASA TV. See the full briefings and events schedule, including briefing participants, at https://go.nasa.gov/2GBCB5A.

SpaceX Demo-1: Reviews provide GO for launch

Additional launch readiness reviews today from NASA’s Commercial Crew Program, space station team, and SpaceX’s launch team concluded the teams are still “go” for launch of the first uncrewed test flight of the Crew Dragon on a mission to the International Space Station.

Launch is scheduled for 2:49 a.m. EST Saturday, March 2 from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. It will be the first time a commercially built and operated American rocket and spacecraft designed for humans will launch to the space station.

At 4 p.m. on Thursday, Feb. 28, NASA will broadcast a prelaunch briefing from Kennedy, with the following participants:

* Kathy Lueders, manager, NASA Commercial Crew Program
* Joel Montalbano, deputy manager, International Space Station Program
* Hans Koenigsmann, vice president, Build and Flight Reliability, SpaceX
* Pat Forrester, chief, Astronaut Office, Johnson Space Center
* Melody C. Lovin, launch weather officer, 45th Weather Squadron

Falcon 9 is on the move to the pad. At least I think that is what I see through the fog. :D
