China's Chang'e-6 Mission Retrieves First-Ever Lunar Far-Side Samples
China made history as its Chang'e-6 lunar probe successfully returned to Earth with approximately 2 kg of rock and soil samples from the unexplored far side of the Moon.
The Historic Mission
The return capsule of China's Chang'e-6 mission touched down safely in the Siziwang Banner of the Inner Mongolia Autonomous Region on June 10, 2026. The mission achieved a global first by successfully collecting and returning approximately 2 kilograms of regolith from the South Pole-Aitken (SPA) basin on the far side of the Moon.
Background & Scientific Context
The far side of the Moon always faces away from Earth due to tidal locking, making direct communication impossible. The SPA basin is the oldest and largest impact crater on the Moon. Scientists believe that samples from this region contain deep-mantle material exposed by the ancient impact, offering unparalleled clues about the early evolution of the Moon, Earth, and the inner Solar System.
Key Statistics & Mission Profile
- Landing Site (Moon): Apollo basin within the South Pole-Aitken (SPA) basin
- Sample Volume: ~2 Kilograms
- Relay Satellite: Queqiao-2 (launched earlier to facilitate communication between Earth and the far side)
- Mission Architecture: Four components: Orbiter, Lander, Ascender, and Returner.
Static GK & Related Facts
- CNSA: China National Space Administration (founded 1993).
- Chang'e Series: Named after the Chinese goddess of the Moon. Chang'e-4 was the first mission to soft-land on the far side in 2019.
- Tidal Locking: The phenomenon where a celestial body takes the same amount of time to rotate on its axis as it does to revolve around its partner, keeping the same face pointed toward it.
