SpaceX's Zuma mission may finally be ready to zoom into space

The launch window opens at 8 p.m. and closes at 10 p.m.

The Falcon 9 lifted off at 8 p.m. EST (0100 GMT on January 9) from Cape Canaveral Air Force Station, on Florida's Space Coast.

SpaceX is scheduled to launch an undisclosed national security payload on Sunday night.

The new nine-engine rocket will launch from pad 39A and will take the secret payload to a low orbit.

The second stage continued carrying the mysterious Zuma to its destination in low-Earth orbit (LEO), while the first stage began maneuvering its way back to terra firma for a touchdown at Landing Zone 1, a SpaceX facility at Cape Canaveral. (SpaceX has had 17 consecutive successful landings, so they're getting pretty good at this).

SpaceX successfully sent something into space for the USA government, and that may be all we'll ever know about the so-called "Zuma" mission that Elon Musk's commercial space company completed from NASA's Kennedy Space Center in Florida Sunday evening.

Success on Sunday will clear the way for SpaceX's next launch from Florida, the much anticipated test flight of the Falcon Heavy booster.

SpaceX just sent a secret government mission to space. The Zuma payload was built by Northrop Grumman for the USA government, but additional information about the satellite is not available.

SpaceX has successfully launched its first mission of 2018, after capping a record year last year in 2017 with 18 total launches.
