SpaceX to Launch U.S. Space Force's X-37B Space Plane on Falcon Heavy

The seventh mission of the reusable X-37B, its first-ever launch on a Falcon Heavy, could reach a higher orbit and carry out the NASA Seeds-2 experiment.

The U.S. Space Force's X-37B space plane is set to launch on a SpaceX Falcon Heavy rocket on Sunday, December 10.
This will be the seventh mission for the X-37B, but its first-ever ride on a Falcon Heavy, which could potentially allow it to reach a higher orbit than usual.
The X-37B is a reusable space plane that carries both civilian and military experiments and can fly in orbit for hundreds of days at a time.
The upcoming mission, known as OTV-7, will carry a NASA experiment named Seeds-2, which will study the effects of long-term cosmic radiation exposure on plant seeds.
The X-37B's previous mission lasted a record 908 days in orbit, and each successive mission has been longer than its predecessors.
