Curiosity is a car-sized Mars rover designed to explore Mars as part of NASA's Mars Science Laboratory (MSL) mission
The MSL mission founded in 1993 was formed to help determine whether Mars could ever have supported life, as well as determining the role of water, and to study the climate and geology of Mars.
The work of MSL is to perhaps best described as helping to set the stage for the human exploration of Mars.
The rover, which is about the size of a MINI Cooper, landed on Mars on August 6, 2012 equipped with 17 cameras and a robotic arm containing a suite of specialized laboratory-like tools and instruments.
Curiosity's scientific tools found chemical and mineral evidence of past habitable environments on Mars. Today, it continues to explore Mars beaming down captivating images and further evidence of the potential for a human mission to take place in the near future.
