Mars has the largest canyon in the solar system. It would reach from Los Angeles to Chicago if it was on Earth! Mars has a very thin atmosphere, mostly carbon dioxide, but dust storms can cover the whole planet for months at a time. About every two years the Earth and Mars come close together. The planet has two moons, Deimos and Phobos. It would take about 6 months for a spacecraft to get to Mars but the crew would have to wait a year and a half before returning. While there are no current plans for a manned mission to Mars you can see some designs at this NASA website, Mars Mission. The nine planets !! This is a little rhyme to remember your planets My very excellent mother just severed us nice pizza Mercy venus earth mars jupiter saturn uranus neptune pluto Stuff we found interesting about mars ! Mars is the fourth planet from the Sun and the seventh largest: orbit: 227,940,000 km (1.52 AU) from Sun diameter: 6,794 km mass: 6.4219e23 kg a picture of the solar system ! Mars is on the inner solar system Mars !! Mars is a small, rock planet which is cold and lifeless. ~The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including the two Viking landers in 1976. After a long break, Mars Pathfinder landed successfully on Mars on July 4, 1997. ~Mars has permanent ice caps at both poles made up mostly of solid carbon dioxide. We know this as "dry ice." ~Very strong winds and vast dust storms sometimes blow through the entire planet for months! ~Mars has two tiny moons which orbit very close to the surface. Their names are Phobos and Some little facts on mars !!! Mars is the fourth planet from the sun and is the seventh largest of the nine planets Mars is the god of War. In Greek mythology, he is known as Ares . The planet probably got this name due to its red color; Mars is sometimes referred to as the "Red Planet." The name of the month March derives from Mars. Mars is also a world famous chocolate bar This is some more stuff on mars Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red colour; 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 terra forming Mars may prefer this symbolism.) The name of the month March derives from Mars. Pictures of mars This is mars!!!! The first spacecraft to visit mars 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 July 4 1997. The temperature on mars Mars' 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 dayside during summer. Where mars is on the solar system!! Mars is the fourth planet from the sun and in a way it, besides the earth, is probably the planet we pay the most attention to. Scientists scramble to unlock the mystery of whether there is life on mars and the public in general has always seemed to have had an interest in the Red Planet. It was named after the Roman God of War whose Greek counterpart is Ares. The most conspicous reason for this is probably that when Mars could be viewed, its deep red color gave the image of blood. Whatever secrets lie in the Red Planet will probably be uncovered soon, for our technology grows fast and so does our curiousity. Surface and atmosphere Surface conditions on Mars are more similar to earth than any other planet in the solar system. However, earth's plants and animals would not survive on Mars. This is because surface temperature on Mars is much lower than that of the earth, hardly ever rising above the freezing point of water. There is evidence that Mars used to have large amounts of water on it millions of years ago, but almost none exists today. But, there is probably frozen water in Mars' polar ice caps or beneath its surface. Mars' atmosphere contains only a slight amount of oxygen, but many scientists believe that some form of life may exist on Mars even though none has been found yet. Even more on the surface and atmosphere There are several outstanding features noticeable on Mars' surface- polar caps, bright areas and dark areas. Numerous craters are present, caused by meteors crashing into the surface. Other features like canyons, gorges and what appear to be dry riverbeds have be photographed by unmanned space probes. This supports the possibility of there once having been large quantities of water flowing on the planet's surface. Mars also has volcanoes, particularly in one region near its equator. The highest volcano on Mars is twice as high as Mount Everest. Near this volcano is a huge canyon that may be a fault line. The moons around mars Mars has two small moons that travel around it. The closest one, Phobos, is also the largest of the two. It has a diameter of about fourteen miles at the equator and about eleven miles from pole to pole. It makes its revolution around Mars in about seven and a half hours. The smaller satellite, Deimos, has a diameter of about six miles and makes its journey around Mars in thirty hours. Asaph Hall, an American astronomer, discovered both the satellites in 1877. Flights to mars In 1965, the unmanned U.S. spacecraft Mariner 4 flew about 6,118 miles from Mars. Four years later, Mariner 6 and Mariner 7 flew even closer to it. Mariner 9 orbited Mars in 1971 and 1972 where it photographed both satellites, a dust storm on the planet and various surface details. Mars 3 , a So viet probe, also orbited the planet in 1971 and released a capsule that made a soft landing on the planet's surface. However, the capsule transmitted information for only twenty seconds when it unexpectedly fell silent. Picture of mars Another picture of mars Thank you for looking at our project !!
