Live coverage: Veteran three-man crew docks with space station

SpaceX’s first Crew Dragon spacecraft, fixed to the forward end of a Falcon 9 rocket, emerged Thursday from the company’s hangar at the Kennedy Space Center in Florida for the quarter-mile journey to its launch mount at pad 39A, where liftoff is scheduled early Saturday on a critical test flight before astronauts strap into the ship later this year.

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.

Commander Mike Hopkins and his three crewmates will board their Crew Dragon “Resilience” capsule Monday for a first-time maneuver to relocate the SpaceX-owned spaceship to a new docking port outside the International Space Station.
