Launching the U.S. Navy’s fifth MUOS mobile communications satellite, a United Launch Alliance Atlas 5 rocket thundered away from Cape Canaveral today.

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.

A prototype for SpaceX’s Starship space vehicle collapsed during pressure testing early Friday at the company’s facility in South Texas — the program’s third failure during such testing since November — but assembly of a new version is already underway.
