Live coverage: Falcon 9 launches ocean study satellite, barge landing fails

SpaceX test-fired a Falcon 9 rocket at Cape Canaveral Friday evening, igniting nine Merlin engines for several seconds while hold-down restraints kept the launcher on the ground. The company also confirmed the rocket is scheduled for takeoff Wednesday on a space station resupply mission, three days later than previously planned.

NASA has agreed to allow its astronauts to fly on reused Crew Dragon spaceships and Falcon 9 boosters beginning as soon as SpaceX’s third launch of a crew to the International Space Station, a mission expected to launch next year.

A SpaceX Dragon cargo ship caught up with the International Space Station early Monday and then stood by while Canadian astronaut David Saint-Jacques, operating the lab’s robot arm, locked onto the spacecraft to wrap up a two-day rendezvous.
