Human Lives at Mars
Facing that the total humans on earth are more than 7 billion, and there is nothing changed on earth size, establishing a permanent colony of humans on Mars is not an option. It’s a necessity. At least, that’s what some of the most innovative, intelligent minds of our age —Buzz Aldrin, Stephen Hawking, Elon Musk, Bill Nye, and Neil deGrasse Tyson — are saying.
Mars is the focus of much speculation and scientific study about possible human colonization. Its surface conditions and the likely availability of water make it arguably the most hospitable of the planets, other than Earth. Conditions on the surface of Mars are closer to the conditions on Earth in terms of temperature, atmospheric pressure than on any other planet or moon, except for the cloud tops of Venus. However, the surface is not hospitable to humans or most known life forms due to greatly reduced air pressure, an atmosphere with only 0.1% oxygen, and the lack of liquid water (although large amounts of frozen water have been detected).
In 2012, it was reported that some lichen and cyanobacteria survived and showed remarkable adaptation capacity for photosynthesis after 34 days in simulated Martian conditions in the Mars Simulation Laboratory (MSL) maintained by the German Aerospace Center (DLR).
NASA and scientist are working really hard to find the possibility to make human can live at Mars. Through their experiments and observation about Mars, they found the possibilities that human can live at Mars. Here is the fact about Mars founded during their experiment :
1. Lose your weight over 62%
Since Mars has less gravity than Earth, your weight will be 62% less than your weight on Earth. This suggests that a person or object that is 100 pounds on Earth will likely weight 38 pounds on Mars.
2. Longer season
Mars has seasons similar to those of the Earth, but longer. The seasons on Mars last about twice as long as those on Earth. However, the length of each season is not exactly the same since Mars has a slightly more elliptical orbit around the sun than does Earth. Spring in the northern hemisphere (autumn in the southern) is the longest season at 194 Sols (Martian days). Autumn in the northern hemisphere (spring in the southern) is the shortest at 142 days. Northern winter/southern summer is 154 Sols, and northern summer/southern winter is 178 Sols. That brings a Martian year to 668 Sols (or about 687 Earth days, about twice as long as an Earth year). A year, of course, is the time it takes for a planet to orbit once around the sun.
3. Sun appears smaller
If you looked at the sun from Mars, it would be substantially smaller than the size of the orb appears on Earth. In fact, it would look like it is half the size. This is because Mars is farther away from the Sun than Earth.
4. Mars has 2 moons
Mars has two small moons, which are called Deimos and Phobos. They have uneven shapes and resemble asteroids. Phobos has a relatively short lifetime expectancy, in terms of moons, at 30-50 million years. Many scientists believe that Phobos was crash on Mars one day. Interestingly, the moons of Mars were written about in Jonathan Swift’s book “Gulliver’s Travels” even before they were discovered!
5. Its a cold planet
Due to Mars distance from sun, it affected to this Red Planet’s temperature. The temperature on Mars can be as high as 70 degrees Fahrenheit (20 degrees Celsius) or as low as about -225 degrees Fahrenheit (-153 degrees Celsius).
In 2030, it’s going to be the largest NASA’s project to bring humans to live at Mars. Do you want to be one of them?
