Snapshots from Atlas 5 launch

The launch of NASA’s Perseverance Mars rover has been delayed two days to July 22 after an issue with ground support equipment at the Kennedy Space Center held up encapsulation of the spacecraft inside the payload fairing of its Atlas 5 rocket.

Along with plans for a moon base, senior NASA managers also outlined work to develop nuclear power systems for use on the moon and Mars to keep astronauts, habitats and other equipment warm while providing the electricity needed for research, construction and daily operations.

An Atlas 5 rocket rumbled into space Saturday evening after lifting off from Cape Canaveral with multiple U.S. Air Force communications and tech demo satellites, and brilliant clear skies made for ideal viewing conditions shortly before sunset.
