Nasa-SpaceX Mission: Crew Dragon astronauts enter Space Station

The US space agency posted a video of Bob Behnken and Doug Hurley stepping into the ISS and being greeted by the three spacefarers who had been living on its board for months

Two Nasa astronauts crossed over into the International Space Station on Sunday after their Crew Dragon capsule docked with the orbital outpost after an hours-long space journey.

"This is the first time in human history @NASA_Astronauts have entered the @Space_Station from a commercially-made spacecraft. @AstroBehnken and @Astro_Doug have finally arrived at the orbiting laboratory in @SpaceX's Dragon Endeavour spacecraft," NASA tweeted.


"It was a tremendous day in mission control as we watched the Dragon approach and then dock, and the hatch open and have @AstroBehnken and @Astro_Doug come forward into the @Space_Station," said NASA Johnson Center Director Mark Geyer.
