Photos: Atlas 5 lifts off with Solar Orbiter

The latest prototype of SpaceX’s  Starship launch vehicle — Starship SN10 — took off from the company’s South Texas test site and flew to an altitude of more than 30,000 feet Wednesday, then descended to a controlled vertical landing after two previous test vehicles crashed at touchdown. Minutes later, the 16-story test rocket exploded in a fireball, but the test flight appeared to be a major step forward in the early stages of the Starship program.

The U.S. Air Force’s fourth new-generation SBIRS missile warning satellite is headed for geosynchronous orbit after lifting off from Cape Canaveral at 7:48 p.m. EST Friday (0048 GMT Saturday), after a one-day delay caused by a troublesome fill-and-drain valve.

The mission is the first of the year for NASA’s Launch Services Program, based at the Kennedy Space Center. The Falcon 9 rocket is lifted off from pad 40 at Cape Canaveral Space Force Station at 1:33 a.m. EST (0633 UTC) on Feb. 8.
