Mars is the fourth planet from the Sun and the seventh largest: \n\n      orbit: 227,940,000 km (1.52 AU) from Sun\n      diameter: 6,794 km\n      mass: 6.4219e23 kg\n\n\n Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. (An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism.) The name of the month March derives from Mars. \n\nMars has been known since prehistoric times. Of course, it has been extensively studied with ground-based observatories. But even very large telescopes find Mars a difficult target, it's just too small. It is still a favorite of science fiction writers as the most favorable place in the Solar System (other than Earth!) for human habitation. But the famous "canals" "seen" by Lowell and others were, unfortunately, just as imaginary as Barsoomian princesses. \n\n\nViking 2 Landing Site  Pathfinder Landing Site The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including Mars 2, the first spacecraft to land on Mars and the two Viking landers in 1976. Ending a long 20 year hiatus, Mars Pathfinder landed successfully on Mars on 1997 July 4. In 2004 the Mars Expedition Rovers "Spirit" and "Opportunity" landed on Mars sending back geologic data and many pictures; they are still operating after more than a year on Mars. Three Mars orbiters (Mars Global Surveyor, Mars Odyssey, and Mars Express) are also currently in operation. \n\nMars' orbit is significantly elliptical. One result of this is a temperature variation of about 30 C at the subsolar point between aphelion and perihelion. This has a major influence on Mars' climate. While the average temperature on Mars is about 218 K (-55 C, -67 F), Martian surface temperatures range widely from as little as 140 K (-133 C, -207 F) at the winter pole to almost 300 K (27 C, 80 F) on the day side during summer. \n\nThough Mars is much smaller than Earth, its surface area is about the same as the land surface area of Earth. \n\n Olympus Mons Mars has some of the most highly varied and interesting terrain of any of the terrestrial planets, some of it quite spectacular: \n\nOlympus Mons: the largest mountain in the Solar System rising 24 km (78,000 ft.) above the surrounding plain. Its base is more than 500 km in diameter and is rimmed by a cliff 6 km (20,000 ft) high. \nTharsis: a huge bulge on the Martian surface that is about 4000 km across and 10 km high. \nValles Marineris: a system of canyons 4000 km long and from 2 to 7 km deep (top of page); \nHellas Planitia: an impact crater in the southern hemisphere over 6 km deep and 2000 km in diameter. \nMuch of the Martian surface is very old and cratered, but there are also much younger rift valleys, ridges, hills and plains. (None of this is visible in any detail with a telescope, even the Hubble Space Telescope; all this information comes from the spacecraft that we've sent to Mars.) \n\n Southern Highlands The southern hemisphere of Mars is predominantly ancient cratered highlands somewhat similar to the Moon. In contrast, most of the northern hemisphere consists of plains which are much younger, lower in elevation and have a much more complex history. An abrupt elevation change of several kilometers seems to occur at the boundary. The reasons for this global dichotomy and abrupt boundary are unknown (some speculate that they are due to a very large impact shortly after Mars' accretion). Mars Global Surveyor has produced a nice 3D map of Mars that clearly shows these features. \n\nThe interior of Mars is known only by inference from data about the surface and the bulk statistics of the planet. The most likely scenario is a dense core about 1700 km in radius, a molten rocky mantle somewhat denser than

Yes i have some interesting facts about mars!!!The belief that there may be life on Mars was popularized in the 19th century, mainly due to the announcement of Martian canals from the observations by Percival Lowell and Giovanni Schiaparelli. Schiaparelli called these observed features canali, meaning channels in Italian. This was popularly mistranslated as 'canals', and the myth of the Martian canals began. They were apparently artificial linear features on the surface that were asserted to be canals, and together with the seasonal changes in the brightness of some areas, they were thought to be linked with vegetation growth. This gave rise to many stories concerning Martians. The linear features are now known to be mostly non-existent or, in some cases, dry ancient watercourses. The color changes have been ascribed to dust storms. \n\n\n\n\n\n\nThere isn't any that we've yet discovered. But there's plenty of evidence that there was once water, and so possibly there was once life, although we've yet to discover any fossils or anything like that. If there was life, it was probably only microbial. But hey, it's a whole planet, who knows what we'll find. \n\n\n\nThere is no life on Mars, however their are all the signs that life was their once since their are large river like gorges covering the planet. Since then Mars' core (i think) cooled to low to support life and so everything cooled. Search for life still continues with little success. \n\n\n\nLife on mars is very possible. It would probably have lived a looooong time ago, back when mars probably had water. Most of that water is frozen in permafrost now though! A mars mission would look for fossil es as well as signs of water being on the surface.

Here is the "face on Mars" area with roughly the same shadows as when the Viking orbiter  first saw it but with higher resolution. I will also link you to an interesting rock face in New Hampshire (it is on the back of the New Hampshire quarter, but some big chunk of it fell off recently.)\n\nBabies can identify something as a face pretty much at birth. This is so hardwired into us we can see face like shapes in lots of things.\n\n"Face" on Mars Images and discussion: http://www.msss.com/mars_images/moc/extended_may2001/face/\n\nMore "face" on Mars images, including a smiley face in a crater: http://www.solarviews.com/eng/face.htm\n\n"Old man of the mountain" in New Hampshire image: http://www.nelsap.org/cam/oldmanbig.jpg

Mars is a bright, red object in the sky. It is very easy to see, which means that even people that lived long ago knew it was there. So, we don't know who discovered it. We do know it was named after the Roman god of war. \n\nA scientist named Giovanni Schiaparelli saw many long lines on Mars. He thought they were water canals made by creatures! Later we sent spacecraft to Mars to study it. \n\nMariner 9 was the first to orbit Mars. It took lots of pictures of volcanoes and craters. It even found Olympus Mons, a giant volcano! The Viking I and II spacecrafts landed on Mars and studied rocks and the soil. Even today the Mars Global Surveyor is mapping the planet!

Discovery of the 10th planet!  Recent discovery.  Not much info. yet so no one can say if you are wrong on any point!

In my astronomy 310 class we discussed missions to Mars, and my professor explained that it COULD be done in a couple years - if there was public interest in it. Since there isn't, and since probes to Mars have been relatively unexciting other than telling us that it used to have water on it before it all evaporated, not many people are too interested in going to a super-hot, rusty, dead planet.

MAYBE YOU SHOULD GO TO A WEB SITE ON ANSTRONAMY OR GO TO THE LIBRARY THERE IS ALL KINDS OF BOOKS ON PLANETS. GOOD LUCK AND GOD BLESS.

Yes, You might have heard about terraforming. Recently i gave a seminar on it. It is the method to transform the mars so that its environment can support life as earth do.  But the only thing required is you and we to get together and work hard with unity for this project. This project is neither going to be of one country or one group but the entire man kind has to work together for it

Mars \nThe planet that is fourth outward from the Sun. Mars has a mean heliocentric distance (semimajor axis) of 1.524 astronomical units, equivalent to 141.6 × 106 mi (227.9 × 106 km). Its orbital eccentricity of 0.093, one of the largest of the major planets, causes the distance between Mars and the Sun to vary from 128 × 106 mi (207 × 106 km) at perihelion to 155 × 106 mi (249 × 106 km) at aphelion. The mean diameter of Mars is 4212 mi (6780 km), or about 53% that of the Earth. The planet has a mass of 7.08 × 1020 tons (6.42 × 1023 kg), about 11% of Earth's. The sidereal rotation period is 24h 37m 22.7s, corresponding to a mean solar day of 24h 39m 35.2s.\n\nMars appears to the unaided eye as a bright, slightly reddish star. Having a mean (synodic) period between oppositions of 780 days, Mars is in conjunction with the Sun every other year. Viewed through a telescope, Mars usually appears as a bright reddish disk marked by complex, semipermanent dark regions and variable white polar caps.\n\nInterior\n\nAccurate measurements of the planet's gravitational field made by orbiting spacecraft have shown that Mars has a dense core and thus is differentiated into a core, mantle, and crust. The crust, composed of silicate rocks, enriched in silicon and aluminum and deficient in magnesium, is believed to be about 30 mi (50 km) thick. Over geologic time, partial melting of the crust or upper mantle has caused lower-density materials to float to the surface, creating the observed lava plains and volcanic structures.\n\nAt present Mars does not have a global magnetic field of appreciable strength. However, early in its history Mars must have had a more substantial magnetic field, because its near-surface rocks exhibit strong remanent magnetism. See also Rock magnetism.\n\nGeology\n\nThe Martian surface has been modified extensively by the processes of impact cratering, volcanism, faulting, and fluvial erosion. The terrain in the southern hemisphere is very heavily cratered and thus quite old, having formed some 3.8 × 109 years ago. Much of it stands 1–2 mi (1–4 km) higher than the planet's mean radius. By contrast, the northern hemisphere is dominated by vast, lava-covered plains with relatively few impact craters and an average elevation of about 3 mi (5 km) below the mean radius.\n\nThe Tharsis rise, or bulge, is an uplifted portion of the surface that stands several kilometers above the mean elevation of the planet. Most of Mars's tectonic features are associated with Tharsis, which affects approximately one-quarter of the entire surface.\n\nThe Martian surface exhibits several enormous shield volcanoes. The largest and perhaps the youngest is Olympus Mons, which is nearly 370 mi (600 km) across at its base and stands approximately 16 mi (26 km) above the surrounding terrain. Three other large shield volcanoes, Ascraeus Mons, Pavonis Mons, and Arsia Mons, lie along the nearby Tharsis rise. In shape and structure the Martian shield volcanoes bear a strong resemblance to their Hawaiian counterparts. At the summit of each shield is a complex of calderas, collapsed craterlike features that were once vents for lava.\n\nPerhaps the most spectacular features on the Martian surface are the huge canyons located primarily in the equatorial regions. Valles Marineris, actually a system of canyons, extends for over 3000 mi (5000 km) along the equatorial belt. In places, the canyon complex is as much as 300 mi (500 km) wide and drops to more than 4 mi (6 km) below the surrounding surface. Dwarfing the Earth's Grand Canyon, Valles Marineris is comparable in size to the great East African Rift Valley. In general, the walls of the canyon are precipitous, have well-defined edges, and show evidence of slumping and landslide activity (Fig. 1).\n\n\nAn image from the Mars Global Surveyor resolves features as small as 20 ft (6 m) in a 10-km-wide portion of Coprates Chasma, which is located in the middle of Mars's vast

Martian geology was first studied using telescope. Then a great improvement was made by having satellites orbiting Mars which obtained satellite images that were transmitted back to earth. Then several missions were send to land robots to study Mars geology. The last mission included several sophisticated devices that can analyze the chemical composition of some samples. The next step will be to collect samples and send them back to earth for analysis.\nAll data collected in Mars is compared to what we know about earth geology, since this will help us understand Mars Geology. \n\nAdditional information can be found at:\n\nhttp://www.marsgeo.com/

Basically all of the surface of Mars except small ice caps (frozen CO2) qualifies as desert - no free water, no rain. The major geographic (or areographic, from Ares - Greek for Mars) features were named after elevations etc. when all the information about Mars came  from early telescopes.\n\nThe Wikipedia article linked below has a topographic map.
