SpaceX has become the first company to dock a commercial spaceship designed to fly people to the International Space Station.

The Crew Dragon was launched on Saturday and docked at 5:51 AM eastern time on Sunday, making it the first American-made, designed-for-crew spacecraft to pull up to the station in eight years.

There were no people on board on the ship, only 400 pounds of cargo and a crash-test dummy, but astronauts aboard the space station were quick to check out the new spacecraft after docking.
