Video: Change of command aboard International Space Station

Ground crews transferred an Antares rocket out of an assembly building to a launch pad on Virginia’s Eastern Shore in a major step before liftoff on Orbital Sciences’ third flight to resupply the International Space Station.

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.

Almost exactly three days after taking off a few miles to the north at the Kennedy Space Center on SpaceX’s historic first crew launch, a 15-story-tall Falcon rocket booster returned to Florida’s Space Coast Tuesday aboard a football field-sized drone ship.
