Four astronauts are back on Earth after a five-month stay at the International Space Station.

The replacements for NASA's two stuck astronauts are on their way to the International Space Station.

NASA and SpaceX scrubbed the Crew-10 launch from Kennedy Space Center on Wednesday evening due to a hydraulic ground issue, officials said.

Crowds are expected along Brevard County beaches as NASA and SpaceX are preparing to launch the Crew-10 mission to the International Space Station.

SpaceX is targeting a Wednesday launch for Crew-10 just after sunset. The team consists of two NASA astronauts, a JAXA astronaut and a Roscosmos cosmonaut. The crew completed a full dress rehearsal of launch day activities on Sunday.

The crew of NASA’s SpaceX Crew-10 mission was at Kennedy Space Center for a test that the space agency says is among the last needed ahead of launch, now less than three weeks away.
