Snapshots from Atlas 5 launch

A SpaceX Dragon supply ship arrived at the International Space Station Saturday carrying a new docking mechanism, a spacesuit for future spacewalks, and a 3D bioprinter to test the feasibility of manufacturing human tissue in microgravity.

Astronauts aboard the International Space Station took these pictures of SpaceX’s Crew Dragon spacecraft as it approached for docking Sunday, a day after launching from the Kennedy Space Center in Florida.

A package of communications and tech demo satellites for the U.S. Air Force rode a United Launch Alliance Atlas 5 rocket into an orbit more than 20,000 miles over the equator after liftoff from Cape Canaveral Saturday evening.
