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
