Snapshots from Atlas 5 launch

A United Launch Alliance Atlas 5 rocket fitted with five powerful solid-fueled boosters has lifted off from a seaside launch complex at Cape Canaveral with the U.S. Navy’s third Mobile User Objective System communications satellite.

The MS-25 mission was scrubbed on Thursday, but the root cause is still under investigation. The earliest that liftoff from the Baikonur Cosmodrome can now occur is Saturday, March 23, pending the outcome of the investigation.

After a one-day delay to wait for improved conditions in the offshore abort zone, SpaceX and NASA launched four astronauts at 5:49 a.m. EDT (0949 GMT) Friday aboard a Falcon 9 rocket and Crew Dragon spaceship from Kennedy Space Center in Florida. The astronauts docked with the International Space Station at 5:08 a.m. EDT (0908 GMT) Saturday for a planned six-month mission.
