NASA’s Mars 2020 Rover. Mars 2020 is the next Mars rover mission by NASA’s Mars Exploration Program. It is intended to investigate an astrobiologically relevant ancient environment on Mars, investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and potential for preservation of biosignatures within accessible geological materials. The rover’s design will be derived from the Curiosity rover, which was launched from Cape Canaveral on November 26, 2011, at 15:02 UTC aboard the MSL spacecraft and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012, 05:17 UTC. But it will carry a different scientific payload. It will also carry a total of 23 cameras: 9 for engineering, 7 for science, and 7 for entry, descent and landing.
