Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it. … A person in the UK uses 70–140 litres of water per day on average.
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. …
He expected to have 1 million people on Mars by 2050, he said in 2020. Musk in February 2021 for the first time ever mentioned a timeline to get humans on the red planet. “Five and a half years,” Musk said. While that’s not a hard deadline.
We will adapt to life on Mars by using technology, and it would actually be easier and faster to add oxygen to the Martian atmosphere, than for us to evolve to live without it!
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.
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.
Earth—our home planet—is the only place we know of so far that’s inhabited by living things. It’s also the only planet in our solar system with liquid water on the surface.
In November 2015, Administrator Bolden of NASA reaffirmed the goal of sending humans to Mars. He laid out 2030 as the date of a crewed surface landing on Mars, and noted that the 2021 Mars rover, Perseverance would support the human mission.
Known as MOXIE, or the Mars Oxygen In-Situ Resource Utilization Experiment, the device is extracting small amounts of oxygen from the Martian atmosphere (which is 96 percent carbon dioxide) by running it through an electrical current, a process called electrolysis. …
They have elongated bodies uncompressed by gravity, and their bones can’t support human weight when exposed to the crushing pressure of life on Earth. It’s possible that people born and raised on Mars would have a similarly difficult time adapting to life on Earth.
NASA is recruiting to send humans to Mars as soon as 2037.

|May be a good investment opportunity||Insecure food supply|
|Humanity needs challenges to move forward||Colonizing Mars can be dangerous|
|Can help with the search for other life forms||Space exploration implies pollution|
To successfully make Mars Earth-like, we would need to raise temperatures, have water stably remain in liquid form and thicken the atmosphere. … To successfully terraform Mars, the atmosphere would need to be raised enough so that humans could walk around without spacesuits.
Ebullism and lack of oxygen would inevitably kill you, so without a suit, a person could survive for about 3 minutes.
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.
Temperatures on Mars average about -81 degrees F. However, temperature’s range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer.
To our knowledge, the Earth is the only planet with an atmosphere of the right density and composition to make life possible.
Air on Venus
The atmosphere of Venus is very hot and thick. You would not survive a visit to the surface of the planet – you couldn’t breathe the air, you would be crushed by the enormous weight of the atmosphere, and you would burn up in surface temperatures high enough to melt lead.
The planet HD 209458b is the first transiting planet discovered, the first extrasolar planet known to have an atmosphere, the first extrasolar planet observed to have an evaporating hydrogen atmosphere, and now the first extrasolar planet found to have an atmosphere containing oxygen and carbon.
To conclude, any new human colonisation on another planet would be very difficult. The extreme weather conditions, the chemistry of the atmosphere and the vast amounts of resources needed to support human life all play into this.
Without a solid surface, Saturn isn’t likely a place we could ever live. But the gas giant does have numerous moons, some of which would make fascinating locations for space colonies, particularly Titan and Enceladus.
While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact – isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet’s surface. Such devices also might one day provide breathable air for astronauts themselves.
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.
