China to expand Tiangong with three new modules—aiming to double station size as ISS approaches end of service

China plans to add three new modules to its Tiangong space station and introduce a co-orbiting space telescope, effectively doubling Tiangong’s size as the ISS heads toward a Pacific splashdown. The upgrade underscores a transition toward a larger Chinese-led LEO presence.

Briefing

What Hype is tracking

  • Tiangong’s planned three-module expansion and “double size” target marks a step-change in long-duration LEO infrastructure at a time when the ISS is moving toward end-of-service.
  • Adding a co-orbiting space telescope links station expansion with dedicated observational capability, shaping downstream science and potential data-access strategies in LEO.
  • The timing against the ISS end-state increases urgency for partners and suppliers to align on operating lifetimes, integration approaches, and future commercialization or research access.
