Mars Exploration Program various components of the EDL systems on Earth-based testing. However, the costs of reproducing environments in which this data would be relevant in terms of Mars' environment are considerably high, resulting in testing being purely ground-based or simulating results of tests involving technologies derived from past missions. InSight, launched from Earth May 5, 2018, the lander touched down on Mars November 26, 2018 on Elysium Planitia. Mars exploration missions, as do most NASA missions, can be fairly costly. For example, NASA's "Curiosity" rover (landed on Mars in Aug 2012) has a budget exceeding $2.5 billion. NASA also has goals of
Rover (space exploration) The Marsokhod was a " heavy" Soviet rover (hybrid, with both controls telecommand and automatic) aimed at Mars, part of the Mars 4NM and scheduled to be released (after 1973 according to the plans of 1970) launched by a N1 rocket that never arrived to fly successfully. The Mars Pathfinder mission included "Sojourner", the first rover to successfully deploy on another planet. NASA, the space agency of the United States, launched Mars Pathfinder on 4 December 1996; it landed on Mars in a region called Chryse Planitia on 4 July 1997. From its landing until the final data transmission on
