  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.

  3. Planetary habitability in the Solar System - Wikipedia

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

    Aside from Earth, no planets in the solar system are known to harbor life. Mars, Europa, and Titan are considered to have once had or currently have conditions permitting the existence of life. Multiple rovers have been sent to Mars, while Europa Clipper is planned to reach Europa in 2030, and the Dragonfly space probe is planned to launch in 2027.

  4. Mars - Wikipedia

    The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds. [185] A Martian year is equal to 1.8809 Earth years, or 1 year, 320 days, and 18.2 hours. [2] The gravitational potential difference and thus the delta-v needed to transfer between Mars and Earth is the second lowest for Earth ...

  7. Planetary habitability - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability

    Mars, by contrast, is nearly (or perhaps totally) geologically dead and has lost much of its atmosphere. [50] Thus it would be fair to infer that the lower mass limit for habitability lies somewhere between that of Mars and that of Earth or Venus: 0.3 Earth masses has been offered as a rough dividing line for habitable planets. [51]

  8. Yellowknife Bay, Mars - Wikipedia

    en.wikipedia.org/wiki/Yellowknife_Bay,_Mars

    With the Mars Science Laboratory's primary goal of establishing whether a habitable paleo-environment could have existed on Mars accomplished while within Yellowknife Bay, the team of NASA scientists then directed Curiosity out of the Yellowknife Bay formation and toward the original destination of Mount Sharp, which rises 5.5 km (3.4 mi) from ...

  9. History of Mars observation - Wikipedia

    en.wikipedia.org/wiki/History_of_Mars_observation

    Earth-based telescopes equipped with charge-coupled devices can produce useful images of Mars, allowing for regular monitoring of the planet's weather during oppositions. [93] X-ray emission from Mars was first observed by astronomers in 2001 using the Chandra X-ray Observatory, and in 2003 it was shown
