KENNEDY SPACE CENTER, FL –  Down range sea states have improved along the flight path and in the abort recovery zone for the overnight predawn liftoff Friday, April 23, of the NASA SpaceX Crew-2 mission on the Falcon 9 rocket and Crew Dragon stack carrying a multinational crew of four astronauts bound for the International Space Station (ISS) from the Florida Space Coast.

“Conditions continue to improve along the flight path and recovery area for the mission,” said NASA.

Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon Endeavor spaceship is retargeted for 5:49 a.m. EDT Friday, April 23, from seaside Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.

The Falcon 9 launch had been postponed a day from Thursday due to poor sea weather in the recovery zones in case of an emergency abort into the Atlantic Ocean after liftoff

Rough sea states with high winds and waves would make recovery of the astronauts extremely difficult in case they had to abort into the northern Atlantic Ocean along the flight path flying in a northeasterly trajectory after blastoff from KSC

The Crew-2 astronauts will fly to the International Space Station for a six-month science mission.

The rocket and capsule remain healthy says SpaceX

 

NASA TV coverage of Crew-2 launch preparations and liftoff will begin at 1:30 a.m. Friday, April 23.

The multinational crew includes two NASA astronauts as well as two from international partners as part of the agency’s Commercial Crew Program – a first for the CCP program.

The  all veteran Crew-2 mission quartet of spaceflyers is comprised of NASA astronauts Shane Kimbrough and Megan McArthur, along with JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet.

Crew-2 thus counts as the first commercial crew launch with two international partners as members of the crew.  Crew-1 has one international partner astronaut from Japan

For an April 23 launch, the U.S. Space Force 45th Weather Squadron continues to predict a 90% chance of favorable weather conditions at the launch pad for liftoff based on Falcon 9 Crew Dragon launch weather criteria.

The primary weather concerns for the launch area will be flight through precipitation from isolated, low-topped coastal showers and onshore flow.

The forecast is also low risk for upper altitude winds and booster recover on the droneship.

The Crew Dragon is scheduled to dock to the space station Saturday, April 24, at approximately 5:10 a.m. EDT.

Meet the Crew-2 astronauts:

The Crew-2 mission marks the second operational crew rotation flight of the SpaceX Crew Dragon and Falcon 9 to the ISS.

Overall Crew-2 will be the 3rd Crew Dragon mission to fly astronauts to space and the ISS in the last eleven months -a remarkable achievement after no human missions were flown from US soil in 9 years after NASA’s space shuttles retired in July 2011.

The quartet of astronauts will also be the first crew to ride to space aboard a previously-flown Falcon 9 booster and simultaneously a reused Dragon spacecraft.

Both vehicles are manufactured by SpaceX and have been carefully refurbished for this mission to ensure safety and reliability.

Crew-2 will fly aboard the Crew Dragon “Endeavour” spacecraft — the same spaceship flown by veteran NASA astronauts Doug Hurley and Bob Behnken on the Demo-2 mission to the space station last year in May 2020 which was also the first flight of US astronauts from US soil in nearly a decade.

The Falcon 9 1st stage is recycled from the Crew-1 mission.
