The fourth rock of the day Mars has long been famous for its fascinating and scientific interest. For decades, robots who explore the red planet, have shown a picture of a marvelous world full of amazing beauty.
Mars is five times as many as the Everest and the Canyon, three times the Grand Canyon, and Mars is a traveler's traveler's paradise. Since the dusty atmosphere, polar caps that change with the season and about 24-hour days, Mars is like a place to hear human visitors.
MARS 2 will return on Wednesday 21:30 AEDT on National Geographic.
As the next major mission of NASA, get ready to touch InSight Lander in late November, and consider the biggest mysteries of Mars.
Is Mars a fluid flow today?
Today, the Marsian atmosphere is so cold and thin that the surface of the liquid is turned off or turned to soil. However, for more than four decades Mars spacecraft has captured images such as hundreds of dried river channels and rapidly flowing water channels.
So, where does the water go? Scientists believe that these erosion features can be left off when Mars is warm and moist, and some can be locked underground, such as ice or deep liquid tanks.
Mars-oriented orbits have shown an abundance of ice-covered ice on the planets. In 2015, images of the NASA's Mars Reconnaissance Orbiter showed evidence of temporary leakage of liquid water on the surface of present-day Marsian. According to the data of the orbit, researchers discovered the chemical fingerprints of hydrated minerals on many dark brown slopes, where mysterious dark stripes were previously identified.
Probably, this ceiling may be flooded by the cold of the cold and when it is cold, Mars leaves. But it is difficult to be sure that these duplicating features are actually realized by water or simple dry contamination without closer examination.
Furthermore, Europe Mars Express Express Orbiter used ground-based radar to detect signs of a 19-kilometer lake beneath the southern polar ice cap of the planet. According to scientists, the underground lake may remain liquid. According to cosmonauts, Mars may have many large reservoirs scattered across polar zones. Knowing how to find them and how to get their reward, the future may be very important for potential researchers who go to Mars.
Why did the northern hemisphere have a hard crater in the flat and southern hemisphere?
In the 1970s, Viking missions of NASA made the first complete study of Mars's topography. From that time on, scientists have no idea why the two sides of the planet are: in the northern hemisphere, the South hemisphere is much flatter than the stronger clayey highs and has a height between 4.8 and 8 kilometers.
Theories suggest that internal geological processes, such as heat convection in the interior mantle, can form modern features of Mars. Thanks to the vast ocean that fills this global basin, the northern hemisphere has been able to grow over time.
For thousands of years, Mars has been interested in humanity, from its vigorous ability to its survival to its potential. Find out how the red planet is formed of gas and dust, and how its polar ice layers affect life.
However, according to these studies, other studies have created a more rigid hypothesis for this incredible dichotomy: a large asteroid of the Earth's moon, 3.9 billion years ago, was displaced to the south pole of the planet. This catastrophic effect was a crucial point in Mars, which concealed the magnetic ocean, causing the red planet's volcanism, which in its turn would destroy the material that composed southern ridges.
By pointing this aspect of the past, scientists can better understand where future researchers want to find the best resources to build sustainable presence.
What is methane generating in the atmosphere of Mars?
Over the last few years, surface telescopes and Mars trajectories have revealed traces of methane to Mars, which may be the result of modern biological activity or may lead to other geological processes.
Recent findings from the NASA's Curiosity rotor have suggested a few months to raise the level of methane in Mars ten times ten times. This indicates that the production of methane is continuing, and it can become the launch site of the robotic Galilee Crater. Although the same gas in the Earth's atmosphere is the result of biological activity, scientists say that these Marsian observations are not solid evidence of microbial life.

NASA believes that the source of this methane is in the north, but its exact location can not be determined. Methane can still be classified as router does not move in this direction and, conversely, focuses on the study of the crushed stones of the central crater.
Is there a life in Mars?
The main ingredient of life, as you know, is liquid water and the signs of Mars presence are hoping to find past or present life. However, the surface layer of Marty is a strongly protected shelter than wild air temperature and harmful UV radiation.
Many scientists believe that dried lakes, such as Gale Crater, can be traced to emptying or traces of previous organic life, and that the NASA is looking for these traces of mega-missions known as the Mars-robotic robot to 2020. There are also signs of extreme forms of life on the planet that are living in the inner space of the planet and are hoping to be alive today. (However, some analysts would send a Mars to people and hunt for someone else's life).
Could people live on Mars?
NASA is planning Mars for the mid-2030s, as well as public and private businesses across the globe to develop the right technology to send people to Mars.
If people survive on Mars, they will have to live and work independently of the Earth and live out of the natural resources of the Red Planet. Underground construction may be required to protect the population from hazardous cosmic rays. Foods that come to Mars are also hard to deal with, because racers have shown that surface soil is sterile and is full of toxic compounds called perchlorate.
Ambitious scientists of spacecraft already plan Mars not only to develop science, but also to plan for future generations of nuclear, chemical and solar-energy technologies that can provide the basis for self-contained human habitat. The most efficient fuel cells and batteries will be required to stay in the dark during the storm of regional or global dust. Transformation of underground and rocky rocks into their boots will be important for the air, breathing, purification of drinking water, rocket fuel and basic building materials.
The only way to solve this mystery is the paruyr of the first expedition on Mars. When this happens, most of us will stick to the screen, and people will be eager to get the following outpost on Mars.
