SpaceX Falcon Heavy Launching X-37B Space Plane Tomorrow

The U.S. military’s X-37B space plane is set to launch Thursday, Dec. 28 in the evening on a SpaceX Falcon Heavy. The spacecraft has a four-hour window starting at 7 p.m. to take off from NASA’s Kennedy Space Center in Florida.

The SpaceX Falcon heavy is at pad 39A to prepare for tomorrow’s launch.

The December launch dates, even with delays, put the X-37B’s next mission launch roughly around the same time as China’s space plane launch. China launched into orbit earlier this month. China for its part is even more secretive about the project, describing it only as a reusable test spacecraft, but the craft is apparently similar to the American one.

Just four days after being launched on its third mission, China’s reusable space plane, Shenlong, aka Divine Dragon, released six unidentified objects in Earth’s orbit. They found mystery objects – designated OBJECT A, B, C, D, E, and F – emitting emissions.
