WHY DO YOU THINK most of the astronomers are interested to study Mars?

Scientists are interested in mars because it is the most earth-like planet in the solar system.It has mountains and valleys,polar ice caps,and dry river beds.Scientists are particularly keen to discern whether water,a key ingredient for life,exists or existed in the past on Mars.

because they never went.\n\nthey have satellite images of mars rovers (tracks in the sand an all!), but not of the lunar landing artifacts.\n\nactualy i'd like to challenge any astronomers out there with the biggest telescopes to zoom in on the landing site during an eclipse or whenever there is no sunlight shinning on it. let's see what comes up.

i do because there are many galaxies are there. but you just wait because in the next 20 years we'll  be able to detect alien life forms other than our planet because if there are those aliens are trying to contact with us by waves (like we use on our planets for example, radio waves.) there is evidence that life used to exist on mars. not like life like us (like mircoscopic things). there are many stories that aliens have come to visit our planet. can be true because as they are as they are described in the movies all these phonomenons are happening buts its not possible for us yet to go visit another galaxy. not eveough human years. but in the next upcoming years we'l have ships that will be able to jump into time. as we are doing right now for example, when a space shuttle stays in orbit for atleast a year, they jump into time by 3.8 seconds. its hard to believe but its true . in star trek when they jump into time there using those worm holes. they exist but there so damn small that we have to enlarge them. there smaller than an atom. as phsyics desribres its not possible to go as fast as the speed of light it'll be possible in the next upcoming years. (i dont no when though) but if we go any faaster than the speed of light we'll be crushed by the gravity so that is why we'll be using worm holes and that is one way that we'll be able to visit other galaxies. i hope i stay alive doing that time lol

Depends on the purpose of going to Mars. If it is for a life of exploration, then I may. The more important factor is...does a significant other get to come along? If I have to go w/ a crew of whoever and spend the rest of my life with them, then no, I wouldn't go.

lol I can't believe you though of that question. They have other things in mind other than sex.  They are thinking about space stuff which is more fascinating than being on earth and they'll problaby forget about sex. Men can't be that horny or are they? They'll  problably do it with a martian or something.

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

MARS... quite possible

It's completely beyond our current science and technology to replicate the environment of Mars with such precision that we could be confident that we'd have the exact same (or even similar) conditions for life as exist on Mars.\n\nIn addition, how would we replicate Mars' environment when we know so little about it?  You'd need to send thousands of probes to Mars to get enough information to even *begin* such an experiment ... and by the time you'd finish that, you could've already run a full set of experiments on Mars testing directly for the past or present existence of native life forms.\n\nA planet's biosphere is an incredibly complicated thing.  It's something that scientists seem to only now be learning about our own biosphere, unfortunately a bit too late.

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

Well extraterrestial planet hunting is only just beginning to be able to discover "smaller" planets. As before only the giant ones indicated their presence, by the effect of their gravity on the parent star.\nRemember even the most powerful telescopes on earth merely see a distant star as a point of light.\nAs for a signal, surveillance equipment is steadily becoming more sophisticated, and discoveries are continously being made to enhance the resolving power of the apparatus. \nMy view is life will not be that common, but a fair few systems will have, or have had life on them at some point. I am sure that in the next twenty years, an umistakeable signal, either intentional or not will be received on earth, and we will know that we are not alone.

At first, I thought, 'sure' but then I realized that we know enough about Mars and after the excitement of lift off and weightlessness, I would be bored to death traveling for months, walking around in a Mars-suit all day while there, traveling for months to get back with a few oxidized rocks... \n\nSo, just save me a ticket to the ISS and I will be happy to go and spend a few weeks touring around this ol' blue planet.

recently probe have been sent to mars to searhc for any signs of organisms or water supplys to suplly evidence that there was life once on mars. So far there have ben pictures sent back showing some sedimentry rocks proving that there was once water on mars, one of the probes landed in a huge crater which was believed to be a lake, since there are signs of water it mean that there must have been  life on mars. Mars wasnt a completly blue planet but there was some water on it, I believe that it was mostly made up of lakes and seas instead of oceans. Btw, the guy who asked to have the best answer, dont do that, you shouldnt demand of of people like that, its the person whos question you answered who decides on who gave him the best answer.

Astronomers are always right except some theories. Because they are doing more than research for this every minute. And i believe that they are right about the black holes.\nBut to make sure that thing they need more research on this.

i think u asked this Q coz u c some movies say that there r aliens on mars.....no scientific proof  says that there r aliens on mars ...NOT on this galaxy ....Maybe there r other creatures in space...WHO knows!....i hav read many books about aliens on mars but they r stories..just stories

I like to think that we will have figured out a way to travel to other stars by then, but that may be wishful thinking. But I would think it is almost a sure thing that people will be traveling pretty regularly to the Moon and Mars by then.

do you really think they dont have telescopes? if they have the tech to transverse solar systems then dont you think they can devise a device to look at us from afar? after seeing what a warring species we are it seems theyd rather study us from afar. we're dangerous.

Very simple answer,have you ever looked at the starts at night, on a clear night, earth and other planets make up the milky way,some sciencetists believe that there many galaxies out there, and why we travel in space, to explore possible live forms and some day find a moon or planet to live, planet earth is in danger from gobial warning, sad to said war and mother nature will tell it all.
