A crewed SpaceX mission to the International Space Station has been postponed by a day due to weather concerns downrange of the launch site, NASA said Wednesday.

Axar.az reports that Liftoff had been scheduled for Thursday but because of unfavorable conditions along the Atlantic coast, it will now be set for 5:49 am (0949 GMT) Friday.

"For crewed missions we need to look downrange to make sure weather's good for a potential launch escape, and for recovery of the crew," acting NASA Administrator Steve Jurczyk told reporters.

The Crew-2 mission will carry four astronauts in the second routine taxi ride by SpaceX to ISS since the United States resumed crewed space flight, and the first with a European.

It involves US astronauts Shane Kimbrough and Megan McArthur, the Japan Aerospace Exploration Agency (JAXA)'s Akihiko Hoshide, and the European Space Agency (ESA)'s Thomas Pesquet, who is French.

The mission is also notable for being the first to use a previously used booster and a previously used capsule -- a key cost-saving goal of NASA's partnerships with private industry.
