The Mars Science Laboratory rover, named Curiosity, launched on November 26, 2011, landed successfully on Mars on August 5, 2012. It is the first NASA mission to use the Multi-Mission Radioisotope Thermoelectric Generator (MMRTG).

Curiosity is collecting Martian soil samples and rock cores, and is analyzing them for organic compounds and environmental conditions that could have supported microbial life now or in the past. Curiosity is the fourth rover the United States has sent to Mars and the largest, most capable rover ever sent to study a planet other than Earth.
