Lunar Reconnaissance Orbiter (LRO)
The Lunar Reconnaissance Orbiter (LRO) launched on June 18, 2009, and remains the cornerstone of modern lunar exploration. Operating seven sophisticated instruments including the Lunar Reconnaissance Orbiter Camera (LROC) and Lunar Orbiter Laser Altimeter (LOLA), LRO has returned petabytes of data: sub-meter images resolving Apollo lunar lander descent stages and astronaut tracks, thermal maps showing the coldest spots in the solar system (-248°C), and 3D terrain models used for Artemis landing site selection.

Primary Achievement
NASA's premier active lunar orbiter; created the highest-resolution global topographic and photographic atlas of the Moon.
Mission Objectives
- Characterize lunar radiation environment, thermal conditions, and illumination at polar regions
- Generate ultra-precise global geodetic grid and sub-meter imagery of high-priority sites
- Identify resource deposits (volatiles, water ice) and assess safe landing hazards for Artemis
