Humans are looking ahead to repeat a history again , a very recent NASA press conference reveal the astonishing fact that the organic matter has found on Mars , which we all know that organic material is the back bone of life.
So are you ready to be the habitat of Red Planet , well hang on although it sounds awesome but the hostility of the environment would fades your excitement, Mars has thin environment , 100 times thinner than Earth which makes it hard for water to flow in form of rivers and thats the reason 95% of Mars surface consists of Carbon Dioxide.
Carbon Dioxide has an adverse effects on humans , Carbon dioxide in its gas form is an asphyxiant, which cuts off the oxygen supply for breathing, especially in confined spaces. Exposure to concentrations of 10 percent or more of carbon dioxide can cause death, unconsciousness, or convulsions. Exposure may damage a developing fetus. So when we be on Mars most likely we be surrounded by carbon dioxide which can be life threatening.
There's something more that you will makes our trip even harder is its severe cold climate , Problem with mars it can't retain heat , the summer day temperature would be around 20C which will down drastically at night to -73C.
On average Mars temperature is -60C , near poles temperature drops to -125C, with that extreme weather conditions humans survival changes are minimal and on top of all the difficulties Mars is usually surrounded by dust storm so take a guess how it would like to walk in a storm!
Another important thing is Mars doesn't have any Ozone layer which leaves the surface vulnerable to solar radiations and flares , It would be the biggest challenge for humans to sustain life on Mars if they happened to land on Mars successfully.
