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 recently launched the seventh mission of its secretive X-37B reusable spaceplane, a Boeing-built orbital test vehicle whose specific purpose and payload are largely unknown.
  • For the first time, X-37B was launched on a powerful SpaceX Falcon Heavy rocket, leading to speculation that this mission could reach deeper orbits or even the moon's vicinity, a significant departure from previous lower-altitude flights.
  • Officially, the mission will test operations in new orbital regimes, explore radiation effects on NASA payloads, and experiment with future space domain awareness technology.
  • This launch closely followed China's deployment of its own secretive Shenlong spaceplane, prompting observers to note a potential new space race between the two nations.
