Live coverage: Orion lands in Pacific

The three U.S. astronauts aboard the International Space Station said Monday they’re ready to sign up for a trip to the moon if NASA can meet the Trump administration’s newly stated goal of returning Americans to the lunar surface within the next five years.

SpaceX launched a Falcon 9 rocket Friday at 5:39 p.m. EDT (2139 GMT). The commercial booster is hauling up the Thaicom 8 television broadcasting satellite from Cape Canaveral. The rocket’s first stage successfully landed on SpaceX’s recovery platform in the Atlantic Ocean.

Fueled segments of the solid rocket boosters that will lift off on the first flight of NASA’s Space Launch System have arrived at the Kennedy Space Center in Florida, but officials will hold off on stacking the boosters until the SLS core stage completes a crucial test-firing later this year.
