Snapshots from Atlas 5 launch

This is the launch highlights reel from United Launch Alliance of the Delta 4 rocket carrying the seventh satellite for the Air Force’s Wideband Global SATCOM constellation.

The rollout of the 322-foot-tall rocket took fewer than 12 hours after first motion, which occurred at about 12:20 a.m. EDT (0420 UTC). NASA hopes to launch the crewed test flight to the Moon no earlier than April 1.

Engineers ran into problems repressurizing the Artemis 2 moon rocket’s upper stage helium tanks overnight Friday, a problem that will require rolling the huge rocket off the launch pad and back to its processing hangar for troubleshooting. The work will push the already delayed mission from March to at least early April, officials said Saturday.
