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.

Defense Secretary Pete Hegseth sent his well wishes to the crew of the SpaceX-NASA mission to retrieve the two stranded astronauts on the International Space Station ahead of their launch tonight. Both of the stranded astronauts are former Navy officers and several of the astronauts on their way to retrieve them are active-duty military members.

With favorable weather forecast at Kennedy Space Center’s Launch Complex 39A, NASA’s SpaceX Crew-10 mission is set to launch at 7:49PM ET tonight. Flying into orbit atop a SpaceX Falcon 9 rocket, the Dragon spacecraft, will dock with the ISS at around 6:00AM ET on March 13th.
