Why did Nasa Chose Mars Not Any Other Plant

The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet's evolution, and preparing for future human exploration. Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind.

A key objective of Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

NASA is still aiming for human missions to Mars in the 2030s, though Earth independence could take decades longer. ... He laid out 2030 as the date of a crewed surface landing, and noted that planned 2020 Mars rover would support the human mission.

As of February 2021, there have been five successful robotically operated Mars rovers, all managed by the Jet Propulsion Laboratory: Sojourner, Opportunity, Spirit, Curiosity, and Perseverance.
