[Mars to stay] would obviate the need for years of rehabilitation for returning astronauts, which would not be an issue if the astronauts were to remain in the low-gravity environment of Mars. We envision that Mars exploration would begin and proceed for a long time on the basis of outbound journeys only. [12]
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.

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.
Microorganisms from Earth traveling to Mars aboard spacecraft would struggle to survive in pockets of salty brine on the Red Planet, a new study suggests. This could be good news for the ...
Scientists have identified a super resilient desert moss species in China's western region of Xinjiang that could help sustain possible colonies on Mars, a study by the Chinese Academy of Sciences ...
This week, explore the technology that could allow humans to live on Mars, uncover the truth of a Neanderthal flower burial, see a leggy birdlike dinosaur, and more.
A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through? is a 2023 popular science book by Kelly and Zach Weinersmith.It covers the current state of knowledge of space settlement given changes in the economics of space travel in the 2010s and 2020s, with a particular focus on challenges that the authors consider unresolved or underestimated.
It traveled just over 22 miles per hour and reached an altitude of 79 feet, proving it could operate in the extremely thin Martian atmosphere. Last week as the helicopter was landing, NASA says ...
