U.S. Space Force’s Secret Robot Spaceplane Could Be Headed to Deep Orbit

Previous flights of the X-37B, built by Boeing, were limited to low-Earth orbit, but its seventh mission could reach new heights.

Key Takeaways:

  • The U.S. Space Force launched its secretive X-37B spaceplane for its seventh mission (USSF-52/OTV-7) using a powerful SpaceX Falcon Heavy rocket, enabling it to potentially reach deeper orbits, possibly near the moon, than any prior mission.
  • The X-37B's specific purpose, payload, and destination are largely unknown, though officially it aims to test operations in new orbital regimes, explore radiation effects on NASA payloads, and advance future space domain awareness technology.
  • This launch underscores a growing "space race" dynamic, as China recently launched its own similar, secretive Shenlong spaceplane, with both nations closely monitoring each other's advancements in this technology.
