Live coverage: Two-man crew departs space station, returns home

SpaceX’s first Falcon Heavy launch for the U.S. Air Force took a major step closer to liftoff with a hold-down engine firing Wednesday night at launch pad 39A at NASA’s Kennedy Space Center in Florida. Liftoff with a cluster of experimental satellites and weather monitoring craft is set for June 24.

Building on development for NASA’s commercial crew program, Space Adventures announced an agreement Tuesday with SpaceX to fly up to four paying space tourists on a standalone mission aboard a Crew Dragon spacecraft in late 2021 or 2022 that could reach an altitude two-to-three times higher than the International Space Station.

Astronauts living on the International Space Station captured amazing views of a Soyuz rocket streaking into orbit from Kazakhstan with nearly 3 tons of supplies destined for the massive research complex.
