Originally planned for a November launch, the mysterious Zuma mission may finally go to space on Sunday evening.
This launch also included a recovery of the first stage booster used with the Falcon 9, which returned to Cape Canaveral and landed at its LZ-1 landing pad after deploying and separating from the second stage.
SpaceX will attempt to launch a Falcon 9 rocket from Cape Canaveral Air Force Station tonight.

SpaceX successfully sent something into space for the United States 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. Just what that business may be is unclear; little has been revealed about the payload.
"As a company, Northrop Grumman realises this is a monumental responsibility and we have taken great care to ensure the most affordable and lowest risk scenario for Zuma", Mr Rains said, declining to comment on the nature of the payload.
We do know that aerospace and defense company Northrop Grumman procured Zuma's launch atop a Falcon 9 for the USA government - but we don't know which agency will operate the satellite, or if its mission is civilian or military.
