Kennedy Space Center

The crew arrived at the station in March after launching from Kennedy Space Center on SpaceX's Falcon 9 rocket.

NASA and SpaceX's Crew-11 mission is made up of two U.S. astronauts, one from Japan and a Russian cosmonaut. They'll be aboard the International Space Station for six months conducting research.

SpaceX, which has gained international recognition for its rocket launches and partnership with NASA, is expanding operations in Florida.

The crew of four will spend two weeks at the orbiting lab, performing dozens of experiments, after launching Wednesday on a SpaceX private flight from the Kennedy Space Center.

It's the fourth mission to the International Space Station for Axiom Space. The Houston company works with SpaceX for rides to the station and coordinates with NASA to use the ISS for its astronauts.

The decision came down with less than an hour remaining in the countdown. Officials say the launch is off until at least Friday.

After launching on Thursday, the Starship rocket caught the booster back at the pad but lost contact with the ascending spacecraft as engines went out. Officials for Elon Musk's company confirmed that the spacecraft was destroyed.

In a two-for-one moonshot, SpaceX launched a pair of lunar landers Wednesday for U.S. and Japanese companies looking to jumpstart business on Earth's dusty sidekick.

New spacesuits, untested astronauts, and a lot that can go wrong make this five-day mission unusually complex, but with a potentially great reward.

An empty Boeing Starliner is scheduled to return from the International Space Station in early September. It will fly home autonomously while its crew remains in space until February.

Three days after launch, the crew will attempt an ambitious and risky spacewalk -- the first for an all-civilian mission.

After years of delay, Boeing's Starliner is flying people for the first time with two NASA astronauts heading to the International Space Station. The rocket lifted off from Cape Canaveral.
