Live coverage: China launches three-man crew to Tiangong space station

A Crew Dragon spaceship built and owned by SpaceX glided to an automated docking with the International Space Station Sunday, delivering NASA astronauts Doug Hurley and Bob Behnken to the orbiting research complex after a trouble-free 19-hour flight from the Kennedy Space Center.

During a visit to Cape Canaveral this week, NASA astronauts Doug Hurley and Bob Behnken strapped in to the SpaceX crew capsule they will ride into orbit as soon as mid-to-late May. Next week, the astronauts will be in Houston to continue training for an extended stay on the International Space Station that could last two-to-three months.

United Launch Alliance called off the launch of a Delta 2 rocket from California’s Central Coast early Tuesday after boats ventured into a restricted safety exclusion zone and engineers ran out of time to resolve a technical problem on the launcher.
