CAPE CANAVERAL, Fla. (AP) — Four astronauts headed to the International Space Station on Sunday where they will oversee the arrivals of two new rocketships during their half-year stint.

SpaceX’s Falcon rocket blasted off from Kennedy Space Center, carrying NASA’s Matthew Dominick, Michael Barratt and Jeanette Epps and Russia’s Alexander Grebenkin.

The astronauts should reach the orbiting lab on Tuesday. They will replace a crew from the U.S., Denmark, Japan and Russia, who have been there since August.

“When are you getting here already?” space station commander Andreas Mogensen asked via X, formerly Twitter, after three days of delay due to high wind. SpaceX Launch Control termed it “fashionably late.”
