To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.Ancient Mars had seasonal weather similar to Earth's, with alternating wet and dry seasons, according to mud patterns discovered by NASA's Curiosity rover. These seasonal cycles may have helped form some of the more complex building blocks for life, such as RNA and basic proteins.However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen.
Did Mars used to have water : Mars once rippled with rivers and ponds billions of years ago, providing a potential habitat for microbial life. As the planet's atmosphere thinned over time, that water evaporated, leaving the frozen desert world that NASA's Mars Reconnaissance Orbiter (MRO) studies today.
Is there oxygen on Mars
Mars atmosphere composition
According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
Can life exist on Jupiter : Potential for Life
While planet Jupiter is an unlikely place for living things to take hold, the same is not true of some of its many moons. Europa is one of the likeliest places to find life elsewhere in our solar system.
Mars may once have been a blue and water-covered world long before Earth even finished forming. That's the tantalizing finding that researchers from Arizona State University and Stanford University announced on October 18, 2022. Mars atmosphere composition

Can we live on Titan
Titan's surface is -180°C. According to one exotic theory, long ago, the impact of a meteorite, for example, might have provided enough heat to liquify water for perhaps a few hundred or thousand years. However, it is unlikely that Titan is a site for life today.Mars' atmosphere is almost entirely made up of carbon dioxide (CO₂) – 96% of the planet's air contains CO₂. Oxygen is only at 0.13%, compared with 21% in Earth's atmosphere.Research suggests Martian soil has some of the nutrients plants need to grow and survive (see “Plants' Nutrients,” right). But because of Mars's extremely cold conditions, plants such as Watney's potatoes would need to grow inside a controlled environment, such as his Hab. The plants would probably be housed in a greenhouse on a Martian base, because no known forms of life can survive direct exposure to the Martian surface, with its extremely cold, thin air and sterilizing radiation. Even then, conditions in a Martian greenhouse would be beyond what ordinary plants could stand.
Can we live on Venus : The surface of Venus is completely inhospitable for life: barren, dry, crushed under an atmosphere about 90 times the pressure of Earth's and roasted by temperatures two times hotter than an oven.
Would life exist on Saturn : Potential for Life
While planet Saturn is an unlikely place for living things to take hold, the same is not true of some of its many moons. Satellites like Enceladus and Titan, home to internal oceans, could possibly support life.
Could we live on Mars 4 billion years ago
But if there was, life on Mars 4 billion years ago would have looked different from what we consider life on Earth. There wouldn't have been humans or animals on the Red Planet, but methanogenic microbes that live on hydrogen and carbon dioxide, reports a 2022 study published in Nature Astronomy. Introduction. Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
Can we breathe in Mars : Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
