A SpaceX Crew Dragon spacecraft carrying four astronauts successfully docked with the International Space Station on Saturday morning. Saturday's docking marks the third time in a year a SpaceX vessel carried astronauts to the station, as well as the first time a previously flown SpaceX spacecraft was reused, CNN notes.
The crew, consisting of NASA's Shane Kimbrough and Megan McArthur, the European Space Agency's Thomas Pesquet, and Akihiko Hoshide of Japan's JAXA space agency, has boarded the station, kicking off a six-month stay in space. Upon opening the hatch and crossing into the station, they were joyously greeted by several astronauts already on board the station, including members of the first team to reach the station via the Crew Dragon, who are headed home next week.
