| Outcome | 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. | China's first lunar mission and the first spacecraft of the Chang'e programme. Operated for 16 months in lunar orbit, producing a complete 3D map of the Moon. Controlled impact on the lunar near-side on 1 March 2009. Demonstrated China's deep-space navigation and communications capability. | 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. |
