A research on the planet mars

The average temperature is about minus 80 degrees Fahrenheit minus 60 degrees Celsiusalthough it can vary from minus F minus C near the poles during the winter to as much as 70 F 20 C at midday near the equator. Inthe United States launched the Mars Odyssey probe, which discovered vast amount of water A research on the planet mars beneath the Martian surface, mostly in the upper three feet one meter.

The density of the atmosphere varies seasonally, as winter forces carbon dioxide to freeze out of the Martian air. Both moons are pockmarked with craters from meteor impacts. Some volcanoes have few craters, which suggests they erupted recently, with the resulting lava covering up any old craters.

Other civilizations also typically gave the planet names based on its color — for example, the Egyptians named it "Her Desher," meaning "the red one," while ancient Chinese astronomers dubbed it "the fire star. In the 19th and 20th centuries, researchers believed they saw a network of long, straight canals on Mars, hinting at civilization, although later these often proved to be mistaken interpretations of dark regions they saw.

Lost missions Mars is far from an easy planet to reach. In the ancient past, the atmosphere was likely thicker and able to support water flowing on its surface. The red planet also causes water-ice snow to fall from the clouds.

Polar caps Vast deposits of what appear to be finely layered stacks of water ice and dust extend from the poles to latitudes of about 80 degrees in both hemispheres. This means that although this desert planet is just half the diameter of Earth, it has the same amount of dry land.

Magnetic field Mars currently has no global magnetic field, but there are regions of its crust that can be at least 10 times more strongly magnetized than anything measured on Earth, remnants of an ancient global magnetic field. Other nations, including China and Russia, have also said they want to go to Mars.

When Mars is closest to the sun, its southern hemisphere is tilted toward the sun, giving it a short, very hot summer, while the northern hemisphere experiences a short, cold winter. The red planet is home to both the highest mountain and the deepest, longest valley in the solar system.

Another mission, InSight, will launch in This difference between the north and south might be due to a very large impact shortly after the birth of Mars. It took the first close-up pictures of the Martian surface but found no strong evidence for life.

InMariner 9 orbited Mars, mapping about 80 percent of the planet and discovering its volcanoes and canyons. They always show the same face to Mars, just as our moon does to Earth. This mission will search for ancient signs of life and, depending on how promising its samples look, it may "cache" the results in safe spots on the Red Planet for a future rover to pick up.

Individual canyons within the system are as much as 60 miles km wide. The lowest of the northern plains are among the flattest, smoothest places in the solar system, potentially created by water that once flowed across the Martian surface. Some craters have unusual-looking deposits of debris around them resembling solidified mudflows, potentially indicating that impactor hit underground water or ice.

Large channels emerging from the ends of some canyons and layered sediments within suggest the canyons might once have been filled with liquid water.

The crust is probably largely made of the volcanic rock basalt, which is also common in the crusts of the Earth and the moon, although some crustal rocks, especially in the northern hemisphere, may be a form of andesite, a volcanic rock that contains more silica than basalt does.

Water may still lie in cracks and pores in underground rock.

Some channels can be 60 miles km wide and 1, miles 2, km long. The cold, thin atmosphere means liquid water likely cannot exist on the Martian surface for any length of time. These were probably deposited by the atmosphere over long spans of time. It remains uncertain whether more water lies underneath, since the probe cannot see water any deeper.

The number of craters on Mars varies dramatically from place to place, depending on how old the surface is. These are made of solid carbon dioxide, also known as "dry ice," which has condensed from carbon dioxide gas in the atmosphere, and in the deepest part of the winter, this frost can extend from the poles to latitudes as low as 45 degrees, or halfway to the equator.

But it could still be weeks, or even months, before skies are clear enough for NASA's Opportunity rover to recharge its batteries and phone home. What is a Planet?

This seemingly simple question doesn't have a simple answer. Everyone knows that Earth, Mars and Jupiter are planets. At least, they are for now. Learn about planet Mars’ atmosphere, water supply and the possibility to support life, plus, findings from the Mars exploration rover mission.

Earth's next-door neighbor is often called the Red Planet because of its red soil. Mars is the fourth planet from the Sun and is the second smallest planet in the solar system. Named after the Roman god of war, Mars is also often described as the “Red Planet” due to its reddish appearance.

Mars Facts: Life, Water and Robots on the Red Planet

The Mars Exploration Program studies Mars as a planetary system in order to understand the formation and early evolution of Mars as a planet, the history of geological processes that have shaped Mars through time, the potential for Mars to have hosted life, and the future exploration of Mars by humans.
