Learn about planet Mars’ atmosphere, water supply and the possibility to support life, plus, findings from the Mars exploration rover mission. The soil of Earth is a kind of regolith, albeit one loaded with organic content. According to NASA, the iron minerals oxidize, or rust, causing the soil to look red. Geology. The cold, thin atmosphere means liquid water currently cannot exist on the Martian surface for any length of time. This means that although this desert planet is just half the diameter of Earth, it has the same amount of dry land.

One-button operation and auto shutoff keep. Olympus Mons is roughly 1. Mount Everest, while the Valles Marineris system of valleys — named after the Mariner 9 probe that discovered it in 1. Mars and close to the width of Australia or the distance from Philadelphia to San Diego. Space. com Exclusive T- shirt. Available to Populate Mars. It is a shield volcano, with slopes that rise gradually like those of Hawaiian volcanoes, and was created by eruptions of lavas that flowed for long distances before solidifying. Mars also has many other kinds of volcanic landforms, from small, steep- sided cones to enormous plains coated in hardened lava. Some minor eruptions might still occur on the planet. Individual canyons within the system are as much as 6. They merge in the central part of the Valles Marineris in a region as much as 3. Large channels emerging from the ends of some canyons and layered sediments within suggest the canyons might once have been filled with liquid water. Some channels can be 6. Water may still lie in cracks and pores in underground rock. 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. The northern hemisphere mostly lies at a lower elevation than the southern hemisphere, suggesting the crust may be thinner in the north than in the south. This difference between the north and south might be due to a very large impact shortly after the birth of Mars. Much of the surface of the southern hemisphere is extremely old, and so has many craters — including the planet's largest, 1,4. Hellas Planitia — while that of northern hemisphere is younger and so has fewer craters. Some volcanoes have few craters, which suggests they erupted recently, with the resulting lava covering up any old craters. Some craters have unusual- looking deposits of debris around them resembling solidified mudflows, potentially indicating that impactor hit underground water or ice. 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 8. These were probably deposited by the atmosphere over long spans of time. On top of much of these layered deposits in both hemispheres are caps of water ice that remain frozen all year round. Additional seasonal caps of frost appear in the wintertime. These are made of solid carbon dioxide, also known as . The dry ice layer appears to have a fluffy texture, like freshly fallen snow, according to the report in the Journal of Geophysical Research- Planets. Credit: Space. com Store Climate. Mars is much colder than Earth, in large part due to its greater distance from the sun. The average temperature is about minus 8. Fahrenheit (minus 6. Celsius), although they can vary from minus 1. F (minus 1. 25 C) near the poles during the winter to as much as 7. F (2. 0 C) at midday near the equator. The density of the atmosphere varies seasonally, as winter forces carbon dioxide to freeze out of the Martian air. The red planet also causes water- ice snow to fall from the clouds. One theory as to why dust storms can grow so big on Mars starts with airborne dust particles absorbing sunlight, warming the Martian atmosphere in their vicinity. Warm pockets of air flow toward colder regions, generating winds. Strong winds lift more dust off the ground, which in turn heats the atmosphere, raising more wind and kicking up more dust. Orbital characteristics. The axis of Mars, like Earth's, is tilted with relation to the sun. This means that like Earth, the amount of sunlight falling on certain parts of the planet can vary widely during the year, giving Mars seasons. 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. When Mars is farthest from the sun, the northern hemisphere is tilted toward the sun, giving it a long, mild summer, while the southern hemisphere experiences a long, cold winter. Composition & structure. Atmospheric composition (by volume). Magnetic field: Mars currently has no global magnetic field, but there are regions of its crust that can be at least 1. Earth, remnants of an ancient global magnetic field. Chemical composition: Mars likely has a solid core composed of iron, nickel, and sulfur. The mantle of Mars is probably similar to Earth's in that it is composed mostly of peridotite, which is made up primarily of silicon, oxygen, iron and magnesium. 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. Internal structure: Scientists think that on average, the Martian core is about 1,8. Orbit & rotation. Average distance from the sun: 1. By comparison: 1. Earth. Perihelion (closest): 1. By comparison: 1. Earth. Aphelion (farthest): 1. By comparison: 1. Earth. The moons of Mars. The two moons of Mars, Phobos and Deimos, were discovered by American astronomer Asaph Hall over the course of a week in 1. Hall had almost given up his search for a moon of Mars, but his wife, Angelina, urged him on — he discovered Deimos the next night, and Phobos six days after that. He named the moons after the sons of the Greek war god Ares — Phobos means . They are tiny next to Earth's moon, and are irregularly shaped, since they lack enough gravity to pull themselves into a more circular form. The widest Phobos gets is about 1. Deimos gets is roughly nine miles (1. The surface of Phobos also possesses an intricate pattern of grooves, which may be cracks that formed after the impact created the moon's largest crater — a hole about 6 miles (1. Phobos. They always show the same face to Mars, just as our moon does to Earth. They may have been asteroids captured by Mars' gravitational pull, or they may have been formed in orbit around Mars the same time the planet came into existence. Ultraviolet light reflected from Phobos provides strong evidence for its capture origin, according to astronomers at the University of Padova in Italy. Within 5. 0 million years, Phobos will either smash into Mars or break up and form a ring of debris around the planet. One NASA plan envisions bombarding Phobos with small, spiky spherical rovers called hedgehogs. Credit: Karl Tate, SPACE. Research & exploration. The first person to watch Mars with a telescope was Galileo Galilei, and in the century after him, astronomers discovered its polar ice caps. In the 1. 9th and 2. Mars, hinting at civilization, although later these often proved to be mistaken interpretations of dark regions they saw. They revealed Mars to be a barren world, without any signs of the life or civilizations people had imagined there. In 1. 97. 1, Mariner 9 orbited Mars, mapping about 8. It took the first close- up pictures of the Martian surface but found no strong evidence for life. A small robot onboard Pathfinder named Sojourner — the first wheeled rover to explore the surface of another planet — ventured over the planet's surface analyzing rocks. It remains uncertain whether more water lies underneath, since the probe cannot see water any deeper. In 2. 00. 8, NASA sent another mission, Phoenix, to land in the northern plains of Mars and search for water. Two orbiters — NASA's Mars Reconnaissance Orbiter and ESA's Mars Express — are keeping Mars Odyssey company over the planet. In 2. 01. 1, NASA's Mars Science Laboratory mission, with its rover named Mars Curiosity, began to investigate Martian rocks to determine the geologic processes that created them and find out more about the present and past habitability of Mars. Among its findings is the first meteorite on the surface of the red planet. A workshop group of government, academic, and industry scientists have found that a NASA- led manned mission to Mars should be possible by the 2. But NASA isn’t the only one with Martian astronaut hopefuls. The Mars One colony project is looking to send private citizens on a one- way trip to the red planet. Possibility of life. Mars could have once harbored life. Some conjecture that life might still exist there even today. A number of researchers have even speculated that life on Earth may have seeded Mars, or that life on Mars seeded Earth. Geologist David Mc. Kay at NASA's Johnson Space Center in Houston and his colleagues focused on rocks blasted off the surface of Mars by cosmic impacts that landed on Earth. Within they found complex organic molecules, grains of a mineral called magnetite that can form within some kinds of bacteria, and tiny structures that resembled fossilized microbes. However, these claims have proven controversial, and there is no consensus as to whether they are signs of life. Although the red planet is a cold desert today, researchers suggest that liquid water may be present underground, providing a potential refuge for any life that might still exist there. The rover Curiosity has found evidence for a lake that could have once supported life on the red planet, after previously establishing that the planet had the key ingredients present for life to evolve.
