Humans will need self-sustaining water, food and oxygen to survive on Mars. Extracting water locked up in ice will be crucial, but with the recent discovery of flowing water on Mars may not be too difficult.
Carbon Dioxide
Mars has an atmosphere, though it is different than our atmosphere here on Earth. The atmosphere of Mars is thin, cold, and dry and contains much less oxygen than the atmosphere of Earth. … So, the animal would have to breathe carbon dioxide, rather than oxygen.
Scientists say some microbes from Earth could survive on Mars, at least temporarily, raising new problems and possibilities for future exploration of the red planet. …
The students found that dandelions would flourish on Mars and have significant benefits: they grow quickly, every part of the plant is edible, and they have high nutritional value. Other thriving plants include microgreens, lettuce, arugula, spinach, peas, garlic, kale and onions.
After the Earth, Mars is the most habitable planet in our solar system due to several reasons: Its soil contains water to extract. It isn’t too cold or too hot. … Gravity on Mars is 38% that of our Earth’s, which is believed by many to be sufficient for the human body to adapt to.

It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure. Upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs ruptured.
At present, Mars’ water appears to be trapped in its polar ice caps and possibly below the surface. Because of Mars’ very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
The average temperature on Mars is minus 80 degrees Fahrenheit — way below freezing! Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth.
Summary: Methanogens — among the simplest and oldest organisms on Earth — could survive on Mars, new research suggests. Methanogens, microorganisms in the domain Archaea, use hydrogen as their energy source and carbon dioxide as their carbon source, to metabolize and produce methane, also known as natural gas.
Despite its thin atmosphere, extreme cold and low oxygen, Mars’ surface is known to contain the majority of plant essential nutrients, including nitrogen, phosphorus and potassium.
Transforming Mars into a life-friendly world doesn’t have to be a herculean planet-wide effort. Humanity could make patches of the Red Planet habitable relatively cheaply and efficiently by placing thin layers of silica aerogel on or above the Martian surface, a new study suggests.
But the gravity on Mars is only 0.38g (about one-third that of Earth’s). This means that moving around on the planet’s surface will be much easier than on Earth – even though any visitors would have to wear protective spacesuits – but crew members may not be able to replace the muscle and bone lost during the journey.

Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.
It made 5 grams of the gas – equivalent to what an astronaut at Mars would need to breathe for roughly 10 minutes. Nasa’s thinking is that future human missions would take scaled-up versions of Moxie with them to the Red Planet rather than try to carry from Earth all the oxygen needed to sustain them.
Some of the issues a Mars suit for surface operations would face include having enough oxygen for the person as the air is mostly carbon dioxide; in addition the air is also at a much lower pressure than Earth’s atmosphere at sea level. Other issues include the Martian dust, low temperatures, and radiation.
Mars has surprisingly powerful snowstorms, which form at night. Although the planet has relatively little water vapour in its atmosphere, clouds of water-ice crystals can still develop. … This atmospheric churning carries water-ice particles downward, where they precipitate out as snow.
Mars is over 50 percent farther from the sun than Earth, so it receives less than half as much sunlight. This, plus the thin atmosphere, makes Mars pretty cold.

AMERSFOORT, THE NETHERLANDS, 31 May 2012 – Today Mars One announced its plan to establish a human settlement on Mars in 2023. Every two years after that a new crew will join the settlement. … While sustaining human life on Mars is not trivial, it is far easier and safer than bringing the crew back to Earth.
