MSL - Mars Science Laboratory Icon MSL - Mars Science Laboratory

The Curiosity rover landed at Gale Crater on August 5, 2012. It is designed to search for and assess past or present habitable environments, i.e., those capable of supporting microbial life.


LRO - Lunar Reconnaissance Orbiter Icon LRO - Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) launched in June 2009 with the objectives of finding safe lunar landing sites, locate potential resources, characterize the radiation environment, and demonstrate new technology.
