SpaceX’s Falcon Heavy rocket blasted again into house on Thursday night time to ferry the U.S. army’s secretive X-37B drone to a analysis mission.

After weeks of delays, the rocket launched from NASA’s Kennedy Space Center in Florida at 8:07 pm Eastern Time (0107 GMT Friday) in a liftoff livestreamed on SpaceX’s web site.

It is unclear the place precisely the uncrewed and autonomously working spacecraft is headed on its seventh mission.

The Pentagon has launched little details about the house drone and its mission, which was initially scheduled for December 7, and SpaceX solely cited the Pentagon’s mission code title — USSF-52 — in its assertion on the launch.

“Falcon Heavy launched the USSF-52 mission to orbit from Launch Complex 39A,” SpaceX stated.

Earlier, the Pentagon had stated the X-37B’s seventh mission would entail “multiple cutting-edge experiments”.

“These tests include operating the reusable spaceplane in new orbital regimes, experimenting with future space domain awareness technologies, and investigating the radiation effects on materials provided by NASA,” the U.S. Department of the Air Force Rapid Capabilities Office stated in a press release final month.

It added that that is the primary time the X-37B is lifting off on a Falcon Heavy, some of the highly effective operational rockets, able to carrying payloads of as much as 26,700 kilograms (58,900 kilos) deep into house.

About the scale of a small bus, the X-37B U.S. house drone seems to be like a mini model of the manned house shuttles retired in 2011. On earlier missions, the X-37B has carried out assessments for NASA on the influence of radiation on seeds and different supplies.

The Falcon Heavy launch comes two weeks after China despatched its personal secretive robotic house aircraft, referred to as Shenlong, into orbit for what state information company Xinhua stated could be a “period of time”.

“During this period, reusable technology verification and space science experiments will be carried out as planned to provide technical support for the peaceful use of space,” Xinhua stated after the December 14 launch.

In operation since 2010, the X-37B Orbital Test Vehicle was designed for the Air Force by United Launch Alliance, a three way partnership between Boeing and Lockheed Martin.

It is 30 toes (9 meters) lengthy, has a 15-foot wingspan and is powered by photo voltaic panels.
