NASA, JAXA, and Roscosmos astronauts join the ISS after a successful SpaceX Dragon mission, welcomed by Expedition 72 crew.

Reaching orbit from NASA’s Kennedy Space Center, the newest crew includes NASA’s Anne McClain and Nichole Ayers, both military pilots; and Japan’s Takuya Onishi and Russia’s Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free.

SpaceX's Crew-10 astronaut mission will arrive at the International Space Station tonight (March 15), and you can watch the action live.

A launch pad problem has forced a flight delay to replace NASA's two stuck astronauts. The new crew needs to get to the International Space Station before Butch Wilmore and Suni Williams can head home after nine months in orbit.

The SpaceX Crew-10 launch is scheduled to take place at 7:48 p.m. EST. The launch will happen at Cape Canaveral at the Kennedy Space Center in Florida. Obviously, spacecraft launches can be delayed for a number of reasons, but assuming there are no technical failures or severe weather changes, the launch should occur before 8:00 p.m. EST.

The two astronauts who crewed the Boeing Starliner have greeted their replacements, who arrived Saturday night at the International Space Station.
