NASA, SpaceX and U.S. Space Force officials said that a launch readiness review went well on Monday, clearing one of the last hurdles toward liftoff of the Falcon 9 booster and Crew Dragon capsule with astronauts Bob Behnken and Doug Hurley aboard at 4:33 p.m. EDT on Wednesday, May 27.

Officials said the launch day forecast for NASA’s Kennedy Space Center in Florida has improved from 60 percent chance of weather violating launch constraints to 40 percent.

Backup dates if the launch is scrubbed are May 30 and 31.

Officials said a brief hot fire of the Falcon 9 boosters first stage Merlin 1-D engines went as planned.

The Crew Dragon mission will be the first orbital launch from American soil since the space shuttle was retired in July 2011.

NASA will provide live coverage on its website of the flight to the International Space Station beginning no earlier than 12:15 p.m. EDT on Wednesday.
