Hauling nearly three tons of supplies, hardware and experiments, a SpaceX Falcon 9 rocket shot into orbit Monday from Cape Canaveral, with a previously-flown Dragon cargo carrier riding a reused first stage booster to kick off a nearly two-day journey to the International Space Station.

SpaceX’s Crew Dragon spacecraft will likely return to Earth in August to wrap up a test flight to the International Space Station with NASA astronauts Doug Hurley and Bob Behnken, a senior space agency official said Tuesday.

Russian Soyuz commander Alexander Misurkin and two U.S. astronauts — flight engineers Mark Vande Hei and Joe Acaba — lifted off Tuesday from the Baikonur Cosmodrome in Kazakhstan. The trio began their six-hour journey to the International Space Station with a launch aboard a Soyuz rocket at 2117 GMT (5:17 p.m. EDT), and docking occurred at 0255 GMT (10:55 p.m. EDT).
