Geologic evidence of past water includes enormous outflow channels carved by floods, ancient river valley networks, deltas, and lakebeds; and the detection of rocks and minerals on the surface that could only have formed in liquid water.The ice-rich polar cap (the quasi-circular white area at center) is approximately 1,000 kilometers (621 miles) across. The white cap is riven with dark, spiral-shaped bands. These are deep troughs that are in shadow. They do not reflect sunlight as well or have more internal layers exposed.Mars water is not drinkable in its current form, as it mostly exists as frozen ice or as very salty brines, making it inhospitable for human consumption.
Did Mars used to have life : 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; Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.
Is the ice on Mars drinkable
The reason scientists need to find subsurface ice is because water on Mars' surface immediately vaporizes due to the planet's thin atmosphere, according to NASA. The buried ice could be drinkable and may also serve as an ingredient for rocket fuel, JPL says.
Would your blood boil in Mars : If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant. You would suffocate, and because of the low atmospheric pressure, your blood would boil, both at about the same time.
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. 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.
Could life exist on Mars
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.Martian soil is toxic, due to relatively high concentrations of perchlorate compounds containing chlorine. Elemental chlorine was first discovered during localised investigations by Mars rover Sojourner, and has been confirmed by Spirit, Opportunity and Curiosity. Dry and extremely cold, with a tenuous atmosphere, today's Mars is extremely unlikely to sustain any form of life at the surface.

Why did Mars lose its water : Chemical changes inside Mars's core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans.
Was Mars once habitable
Although we know early Mars was wetter, warmer and more habitable than today's freeze-dried desert world, researchers have yet to find direct proof that life ever graced its surface. The two worlds diverged, and we have two very different planets today. Despite the fact that Mars may once have been warm and wet, it is now a cold, dry place. As the Earth progressed with plate tectonics and the development of life, Mars' geologic activity subsided, lost water, and it became a much drier planet.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.
Is Mars OK to live on : The air on Mars is thinner than that on Earth. On Earth, 21 percent of the air is oxygen, which is what makes it the ideal place for human life. But on Mars, oxygen makes up 0.13 percent of the air. The majority is carbon dioxide, which is harmful to humans.
