Wanting to know about the life on planets Mars, finding the clues of existing life beyond Earth and of Mars has been a goal of national space agencies for decades. Wernher von Braun was the first person to make a detailed technical study of a Mars mission in his book Das Marsprojekt. This book is published in English in 1962 and after that, several articles were published in the March 1952.
After that, many researches and experiments, space agencies has been decided to send human beings including Pakistan's ex-military man to Mars and named this idea as “Mars to Stay mission”. For this purpose, a series of proposals were taken place. After that, thousands of people are prepared to leave their families, jobs and even the Earth and lives behind for a one-way trip to Mars. It seems to be adventurous, but truly speaking, this voyage is totally dangerous and contains lots of risks. It is the six-month journey, no way to return back. With creating curiosity about the life on Mars, experts also address the risks which could be a hurdle in the journey. According to them, radiation and zero-gravity on Mars are unduly hazardous. A researcher claims cancer rates do increase for astronauts who have spent extensive time in space, but only marginally. Zero-gravity presents challenges, near total recovery of musculature and immune system vitality are presumed by all Mars to Stay mission plans once settlers are on the Martian surface. Due to low gravity environment on Mars, There may be negative effects on human health, including loss of eyesight, etc... In accordance to stay on Mars, NASA centers on Earth provide much better training ground for the people who are interested to move to Mars and are ready to face challenges at lesser cost ( but at the cost of their own life, at their own risk ).
Mars having Channels, valleys, and gullies, all over there and suggest that liquid water might have flowed above the planet surface in recent times. Most channels have been 60 miles ( 100 km ) wide, and 1,200 miles ( 2,000 km ) long. Water also flow in cracks and pores in underground rocks.
Temperature of Mars is very cold than compare to Earth, because of its greater distance from the sun. The average temperature is minus 80 degrees Fahrenheit ( minus 60 degrees Celsius scale ), although they can be change and vary from minus 195 F (minus 125 C) near the poles during the winter to as much as 70 F (20 C). It is very difficult to live in that temperature.
