Briefing

What Hype is tracking

  • Demonstrates end-to-end navigation and rendezvous capability for deep-space small-body exploration, with Tianwen-2 reaching ~20 km and transitioning into observation operations.
  • Enables the start of detailed scientific study of a specific asteroid target, supporting China’s broader solar-system science objectives.
  • A successful proximity phase reduces mission risk and validates the mission’s choreography for long-duration, high-delta-v pursuit at extreme distances.
