A Falcon 9 rocket lifted off from Vandenberg Air Force Base at 4:39 a.m. PDT (7:39 a.m. EDT; 1139 GMT) Wednesday, and SpaceX successfully landed the rocket’s first stage on a drone ship in the Pacific Ocean. The mission’s primary objective is the deployment of 10 Iridium Next communications satellites into low Earth orbit.

A U.S. military satellite awaiting launch Friday night from Cape Canaveral is small enough to fit on a coffee table, but it will punch above its weight, scanning a region more than 20,000 miles above Earth to catalog spacecraft movements and space junk.

OneWeb — three launches into a series of nearly 20 missions to deploy 650 satellites to provide global Internet service — has announced it filed for Chapter 11 bankruptcy protection and reduced its workforce after unsuccessful negotiations for more cash from its largest investor.
