Snapshots from Atlas 5 launch

SpaceX’s Falcon Heavy rocket lifted off from NASA’s Kennedy Space Center in Florida at 2:30 a.m. EDT (0630 GMT) to begin a three-and-a-half hour mission to deliver two dozen satellites into three distinct orbits. The Falcon Heavy’s two side boosters returned to Cape Canaveral for successful landings, but the center core stage crashed during a landing attempt on SpaceX’s drone ship in the Atlantic Ocean.

NASA has added extra safeguards to the agency’s standard pre-launch quarantine protocol to protect astronauts Bob Behnken and Doug Hurley from the coronavirus and other contagions in the final two weeks before their scheduled May 27 launch on SpaceX’s Crew Dragon spacecraft.

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.
