  2. Life on Mars - Wikipedia

    en.wikipedia.org/wiki/Life_on_Mars

    At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there. [5] [6]

  3. Planetary habitability in the Solar System - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability_in...

    Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.

    While humans can breathe pure oxygen, usually additional gases such as nitrogen are included in the breathing mix. One possibility is to use in situ nitrogen and argon from the atmosphere of Mars, but they are hard to separate from each other. [63] As a result, a Mars habitat may use 40% argon, 40% nitrogen, and 20% oxygen. [63]

    The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) [1] was a technology demonstration on the NASA Mars 2020 rover Perseverance investigating the production of oxygen on Mars. [2] On April 20, 2021, MOXIE produced oxygen from carbon dioxide in the Martian atmosphere by using solid oxide electrolysis .
