The commercially developed SpaceX Crew-2 Dragon ship carrying a group of four astronauts from the United States, Japan and France successfully docked with the International Space Station on Saturday following its liftoff from NASA's space center a day earlier, Kyodo reported. Two NASA astronauts -- Shane Kimbrough and Megan McArthur -- along with Akihiko Hoshide of the Japan Aerospace Exploration Agency and Thomas Pesquet from the European Space Agency will begin an approximate six-month mission at the orbiting laboratory.
