Any interesting facts aabout the planet Mars?

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.

Mars is much smaller than Earth.  About 1/2 the diameter (0.53), and 1/10 of the mass (0.107) of the Earth.\n\nHere's a great set of illustrations showing the relative sizes of all the planets, and the sun.\n\nhttp://www.comagz.com/webmagazine/story/proportions_how_small_we_are

The rotation of Venus is believed to have been caused by a huge planetary impact that occurred very very early in the formation of the planet.  A similar event is thought to have happened to Earth and it lead the the formation of the Moon.  As for life previously existing on Mars, I think it is possible.  However it was probably only microscopic bacteria-like organisms.  We will never now until humans do some on-site digging in the Martian crust.

On average, 2,432,890.5 miles per day. (Mars orbital circumference of 888,005,041 miles divided by 365 days.)

I think very soon there will be.  google.com/mars is very close.  Unfortunately, there's nothing really on Mars to check out.  Plus you can't get to the same resolution (obviously) as on Earth.\n\nVenus is even harder - there aren't really any well known features on Venus, and everything will be computer images based on radar telemetry.\n\nBut one day...\n\n.

Why do we live in Mars ?

Mars has some of the correct properties for having had organic life from the Viking landing. No findings of old organic compounds. I think one mission just landed in an old crater that may have been one of the last places to have water so maybe the best chance to find something. Also, Europa is covered with ice and the tidal forces may keep it warm enough to make life. Galileo probe may find more.

Yeah.   I reckon we should first study Mars in its pristine form for a few decades.   By then we'll have the technology to terraform it, so we'll have somewhere to run to when we screw up Earth.

The main reason Mars is colder is that it is much father way from the sun. Also the atmosphere is so this, it does not insulated the planet much at all.

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

Go to Heavens Above.  They have a lot of information about the planets, as well as satellites that have been placed in orbit or sent out into the solar system.\n\nhttp://www.heavens-above.com

Sorry, but there is no evidence of life on Mars.  But, scientists have very strong beliefs that it may exist on Mars and other planets.  The type of life that may exist would be microscopic.

not sure about the mass and size, i always thought mars is bigger than earth? just are you sure your questions are sensible coz as far as i remember, we on earth are still trying to figure out how to get there.
