Watch live: Vice President Pence visits Kennedy Space Center

SpaceX’s next Crew Dragon capsule was delivered to Cape Canaveral this week from a California factory for a liftoff as soon as this spring with veteran NASA astronauts Doug Hurley and Bob Behnken on a test flight to the International Space Station, officials announced Friday.

SpaceX called off the planned launch of a Falcon 9 rocket Saturday less than 15 seconds before liftoff to investigate the “slightly odd” behavior of the vehicle’s upper stage engine steering system, company chief Elon Musk said.

SpaceX launched its fifth Falcon 9 rocket in 22 days on Saturday, beginning a mission to deploy 52 more Starlink internet satellites and two rideshare payloads for Capella Space and Tyvak Nano-Satellite Systems. Liftoff from pad 39A at NASA’s Kennedy Space Center in Florida occurred at 6:56 p.m. EDT (2256 GMT), and SpaceX successfully landed the first stage on a drone ship in the Atlantic Ocean.
