Photos: Predawn launch of Atlas 5

Student-built miniature satellites to demonstrate 3D printing to make repairs in space, a mission to study solar explosions hitting the Earth, a technology test for deorbiting smallsats and a precursor to a commemorative time capsule have won free launches into space aboard Atlas 5 rockets in United Launch Alliance’s first-ever cubesat challenge.

This video released by United Launch Alliance shows the Delta 4-Heavy rocket’s predawn liftoff Aug. 12 from the perspective of a downward-facing camera, capturing dazzling views of the fiery takeoff and the dramatic separation of the launcher’s two hydrogen-fueled boosters.

Running nearly two months late after technical concerns prevented liftoff last year, a SpaceX Falcon 9 rocket fired into the sky Sunday night from Cape Canaveral with a top secret payload for the U.S. government, the first of some 30 launches on the company’s docket in 2018.
