Photos: Atlas 5 rocket aims for International Space Station

The two Geosynchronous Space Situational Awareness Program, or GSSAP, satellites for the U.S. military are mounted aboard the United Launch Alliance Delta 4 rocket. Liftoff is planned for Aug. 19 from Cape Canaveral.

Seven small satellites from Canon Electronics, Planet and In-Space Missions launched from New Zealand on Rocket Lab’s Electron rocket Saturday at 5:19:36 p.m. EDT (2119:36 GMT), but the payloads and launch vehicle were lost after a problem during the second stage burn.

The SpaceX Crew Dragon spacecraft that carried four astronauts to the International Space Station in November broke the record Sunday for the longest spaceflight by a U.S. crew vehicle, surpassing the 84-day mark set by an Apollo capsule on the final flight to the Skylab space station in 1974.
