| Outcome | South Korea's first lunar spacecraft, a joint KARI–NASA mission. The NASA-provided ShadowCam instrument has revealed unprecedented detail inside permanently shadowed polar craters that could host water-ice. The mission is on an extended science phase as of 2026. | Chang'e 2 far exceeded its primary mission. After completing its lunar mapping goals, it traveled to the Earth-Sun L2 point (first Chinese L2 mission), then flew past asteroid 4179 Toutatis at 3.2 km — the closest-ever asteroid encounter. Now in a heliocentric orbit, drifting beyond Mars. | ESA's first mission to the Moon and Europe's first use of Hall-effect ion propulsion in deep space. SMART-1 took 14 months to spiral from GTO to lunar orbit using its ion engine, validating technology for future missions. Deliberately impacted the Moon's near side on 3 September 2006. |
