NASA robots craft that will be designed to fly in a formation. The Mars rover Curiosity is a mobile laboratory that was launched from Cape Canaveral in 2011. The Curiosity landed on Mars surface August 6, 2012. This was the largest rover NASA has put on Mars, being twice as long and five times as heavy as its processors. Despite the extra size the Curiosity took many design elements from the previous generation of Mars rovers such as six wheel drive, rocker-bogie suspension, and cameras mounted to the mast of the rover to help the mission's team direct the rover. However unlike
Mars sample-return mission an orbiter, a fetch rover, and a Mars ascent vehicle (MAV). In mid-2006, the international Mars Architecture for the Return of Samples (iMARS) Working Group was chartered by the International Mars Exploration Working Group (IMEWG) to outline the scientific and engineering requirements of an internationally sponsored and executed Mars sample-return mission in the 2018–2023 time frame. In October 2009, NASA and ESA established the Mars Exploration Joint Initiative to proceed with the ExoMars mission, whose ultimate aim is "the return of samples from Mars in the 2020s". A first step in this was one particular proposal, a joint project between
