SpaceX plans to launch the secret Zuma payload for the U.S. government this evening (Jan. 7), after a nearly two-month delay.
Zuma is scheduled to lift off atop a two-stage Falcon 9 rocket from Florida's Cape Canaveral Air Force Station tonight between 8 p.m. and 10 p.m. EST (0100 to 0300 GMT on Jan. . You can watch it live here at Space.com, courtesy of the company. You can also watch the liftoff directly from SpaceX's live webcast page here.
Sunday's launch will also include a landing attempt by the Falcon 9's first stage, which will come back down to Earth at Landing Zone 1, a SpaceX facility at Cape Canaveral. To date, SpaceX has pulled off 20 such first-stage landings, which are part of its push to develop fully and rapidly reusable rockets. [SpaceX's Zuma Launch: Here's What We Know]
Zuma is a U.S. government spacecraft headed to low-Earth orbit. But that's pretty much all that outside observers know about it; everyone involved with the mission has remained pretty tight-lipped.
