US astronauts Doug Hurley and Bob Behnken have docked with the International Space Station (ISS) short-while ago.
Their Dragon capsule – provided by the private Space vehicle company SpaceX – edged them into port on the high-flying lab’s bow section.
Two crew members now will have to wait for leak and pressure checks to be completed before they can disembark and join the Russian and American crew already on the ISS.
SpaceX dragon capsule launched onboard with Hurley and Behnken from Florida on Saturday. It was the first time since the retirement of the shuttles nine years ago that the US space agency has sent up astronauts from home soil.
The mission marks the beginning of a new era in which NASA will be purchasing transport services from the commercial sector. No more will it own and operate the vehicles that run to and from the station.
This will be done, as in this case, by firms like California’s SpaceX outfit, which is led by tech billionaire Elon Musk.
Confirmation of the Dragon’s attachment at the ISS came at 14:16 GMT (15:16 BST), slightly ahead of schedule, 422km (262 miles) above the border between northern China and Mongolia.
