Astronomy Science ~ The idea of ​​life on Mars has become a staple of science fiction since the 19th century, when American astronomer Percival Lowell speculated that he saw the Red Planet channel and channel it really ancient canals built by intelligent extraterrestrials.

But if this science fiction into reality, what it was like to live on Mars?

In 1965, NASA's Mariner 4 spacecraft successfully flew past Mars for the first time and six years later, the Soviet Union Mars lander 3 became the first spacecraft to land softly on Mars. Since then, there are many successful mission to the Red Planet, including four rover Mars landing - Sojourner and the Spirit that is now defunct and Opportunity and Curiosity is still active. Meanwhile NASA's Mars Odyssey spacecraft has mapped the entire planet Mars.

NASA now plans to send a manned mission to Mars, which is scheduled in the 2030s.


Like Earth, Mars has seasons because of the slope of the planet on its axis, but also has a seasonal effects secondary to a highly elliptical orbit. Martian southern hemisphere leads away from the sun when the planet is at its farthest from the Sun, so it is much colder winter (and summer is much hotter) than the northern hemisphere of Mars.

If you live in the northern hemisphere of Mars, you'll enjoy about seven months of spring, summer six months, five months of autumn and only about four months of winter. (A year on Mars about 1.88 Earth years, and one day lasted a little more than 24 hours.)

The average temperature on Mars minus 80 degrees Fahrenheit (minus 60 Celsius), but the temperature can range from minus 195 F (minus 126 C) in the winter near the poles to 68 F (20 C) during the summer near the equator. Temperature can also change dramatically within a week.

Temperature variations in Mars' often lead to strong dust storms, which can sometimes envelop the entire planet in just a few days. Although this storm probably will not hurt you physically, but this dust can clog electronic devices and interfere with the solar-powered instrument, Vasavada said.

With the density of the atmosphere is only 1% of the density of the Earth, the Martian atmosphere is thick enough to burn a small meteor meteor the size of marbles to larger so you might not get hit by them, said Vasavada. You also do not need to worry too much about the volcanic and tectonic activity while living on Mars.

"It dreaded number 1 if living on Mars is radiation from outer space," said Vasavada. Unlike Earth, Mars does not have a global magnetic field and a thick atmosphere to protect the surface from radiation.

If you are experiencing some unfortunate incidents in Mars, the message you send back to Earth will take an average of 15 minutes to get there. Although it is not too long, "it certainly is quite disturbing because you would be hard to make calls or video calls to anyone," said Vasavada.

In terms of weather, you might see the occasional thin clouds or ice cold in the morning because the air of Mars contains low humidity. But you will not find in the sky storm clouds or rain that reaches the ground.

With a clear sky, Mars will be a starry night. Moons of Mars, Deimos and Phobos, may appear at the same time. These satellites, which are both much smaller than Earth's moon, also can make a partial eclipse of the sun during the day.

Daytime sky generally have orange, this was due to dust, Vasavada said.

Surface of Mars offers a great opportunity for travel. "If we really colonize Mars, of course there are places that will be a national park," said Vasavada.

For example, Olympus Moons is the highest volcano in the solar system, reaching a height of 16 miles (25 kilometers) above the surface. On the other hand, Valles Marineris, a giant chasm that has the distance from Los Angeles to New York. And you also might want to visit the Viking lander sites and amazing ice at the poles of Mars', which sometimes produces dry ice snow, Vasavada said.

But with gravity only 38 percent of the earth, Moving on Mars would be challenging at first. "We may have a bit to learn back when walking and moving fast on Mars," said Vasavada. "But there is better than moving in a moon."
