Snapshots from Atlas 5 launch

United Launch Alliance, a union of Atlas and Delta rockets formed a decade ago for U.S. government spacelift needs, will conduct its 25th deployment mission for the country’s spy satellite agency Thursday night.

NASA has selected SpaceX’s Falcon Heavy rocket to launch a robotic mission in July 2022 to explore Psyche, a metal-rich asteroid located between the orbits of Mars and Jupiter. The Psyche probe is NASA’s first mission assigned to fly on SpaceX’s heavy-lift launcher.

A United Launch Alliance Atlas 5 rocket, flying in its basic two-stage configuration with no strap-on solids, was stacked aboard a mobile launch platform at Cape Canaveral’s Vertical Integration Facility on Feb. 22 and 23 in preparation to send Orbital ATK’s S.S. John Glenn cargo ship into orbit for the International Space Station.
