In einer seltenen Offenlegung stellt das Pentagon ein Update zum Raumflugzeug X-37B bereit

>While the reusable Boeing-built X-37B spaceplane is designed to land like an aircraft on a runway, the service module, mounted to the rear of the vehicle, carries additional payloads. At the end of the mission, the X-37B jettisons the disposable service module before reentry. ***The Space Force doesn’t want this section of the spacecraft to remain in its current high-altitude orbit and become a piece of space junk.***

Translation “we’d very much rather this impact the planet at a high velocity after cooking through re-entry.”
