Videos: Previewing SpaceX’s eighth International Space Station resupply launch

SpaceX aims to launch a Falcon 9 rocket Monday from Vandenberg Air Force Base in California with 10 new satellites for Iridium’s tracking and message relay constellation in low Earth orbit.

A Falcon 9 rocket booked to launch a commercial communications satellite for Hispasat, a Madrid-based telecom company, fired its nine main engines late Tuesday night at Cape Canaveral for a pre-flight hold-down test.

United Launch Alliance teams ran through an 11-hour countdown Friday at Cape Canaveral to rehearse procedures before the first flight of a modified Atlas 5 rocket with Boeing’s Starliner crew capsule Dec. 20.
