SPACEX are to launch a top-secret satellite codenamed project Zuma this Friday, the US Air Force confirmed.
The mysterious project will see the private space agency launch the satellite allowing an unnamed government organisation to send messages or take photos.
One of the few scraps of information currently available has revealed Zuma will enter into a low orbit around Earth.
What the orbiter's mission is and who will be operating it is unknown with US authorities so far refusing the release any more information.
The satellite will be launch on SpaceX’s Falcon 9 rocket from the Kennedy Space Centre in Florida.
The launch was first pencilled in for the middle of November but was eventually pushed back so SpaceX could analyse their data for a previous launch
As one Falcon 9 will leave as another returns with a rocket also landing on Friday.
SpaceX will launch the mission from the Kennedy Space Centre between 8.00pm and 10.00pm.
Elon Musk’s firm has carried out government missions before but never as secretive.
News of the mysterious satellite comes after SpaceX programme was revealed to be planning to send a Telsa to Mars.
The car will reportedly be playing David’s Bowie's Space Oddity on a loop.
The billionaire businessman took to social media to announce that he will send a Tesla car to Mars.
Mr Musk announced on Twitter that he will be sending a “cherry Tesla Roadster” to orbit Mars, playing David Bowie’s ‘Space Oddity’ on repeat and that it would “be in deep space for a billion years or so if it doesn’t blow up on the ascent.”
However, he later back-pedalled on this statement by saying that he was not sure if SpaceX’s Falcon Heavy rocket craft would carry the electric vehicle to the Red Planet.
But now the South African born American has now left no doubt in anyone’s mind that SpaceX will be sending a car to Mars after he posted a series of pictures on Instagram of the red Tesla Roadster inside the Falcon Heavy.
Alongside the images, Mr Musk put: "Test flights of new rockets usually contain mass simulators in the form of concrete or steel blocks.
"That seemed extremely boring. Of course, anything boring is terrible, especially companies, so we decided to send something unusual, something that made us feel.
"The payload will be an original Tesla Roadster, playing Space Oddity, on a billion-year elliptic Mars orbit."
