As has already been mentioned we have at least two very fine robots on Mars.  But to make it possible for humans to make the trip, there are a number of problems.  It is a very long way to go and people need to survive the distance and still be in good enough physical condition to move around the surface of Mars.  They also need to have sufficient fuel to make the round trip.  NASA has been generating plans for such an operation for years and it continues to work on them.  For the most current ideas, try going to "www.NASA.gov" and searching the site for topics about Mars.  You'll learn a lot about the program.

It might be possible although it'll be a lot more expensive than building space settlements and there is also the issue of the lower gravity (we don't know how that will affect the colonists).\n\nIf the gravity issue is solved we might be able to colonise the planet in that timeframe.  The materials needed are mostly there but we'd have to bring a lot of technology and softland it on Mars.  This will include mining technology, fabrication technology and power sources (probably nuclear).\n\nWater could be a problem but we should be able to import it from asteroids and comets so if there isn't any left on Mars it can be obtained from elsewhere without too much trouble.

Mars is not hot. It's pretty cold. The average surface temperature is -8°C. In best conditions, it takes about a month to get there. The trip would be on a spaceship and you'd be PARTYING!

yes.  Here is a post of mine with the info on it about life outside our planet, maybe even in our solar system.  Be aware:  Most planets we found are "hot jupiturs", which are jupitur sized gas giants with temperatutres about 1300F at average.  \n\nThere is a possibility.\n\nI have done PLENTY of research in astronomy. I just am so into it. Anyway, I beleive yes, and my reasons:\n\nEarth itself seems perfect. Perfect climate, actaul liquid water, etc. But did you know animals (and I mean animals, not bacteria) could adapt over time to certain places? For instance, In Jupitur, there might be life. The appearence: Most planets are gas giants, and they need to be able to withstand a good amount of temperature (We are alomst guarenteed the only solar system with rocky planets and temperatures colder than 1300F on average). This would be the perfect place for, as the books described as, Floaters And Swordtails. Floaters kinda would be blimps. They would be organisms flying in the perfect temperature zone and flying with the baloons on their back. However, a sword tail would come. Using its super wings, it can fly lightning fast. Its sharp beak lets it tear right through the floater for food.\n\nOn EUropa:\nOn jupiturs smallest of the Gallelaio moons, there is a greater chance of having life than mars. The reason: Ice flows cover the surface. The ice flow tend to crack, bu recover. The process is also found on earth, and is now beleived that liquid water lies under the flow.\n\nThe appearance of life:\nSkating on the ice on Europa, An unnamed organism skates around, using its green body to undergo photosynthesis to produce food. Because It needs no air and makes food like plants, they need no mouths.\n\nVenus (What most planets moons probibly look like):\nOn a hot planet like venus, you need to survive insane temperatures. Eating rocks would also be good, for the fact that its mostly the only thing on the planet. Oh, and leave out the need for water. They cant get any there. \n\nThe appearence: \nStanding on the scraps of a russian probe, an oucher-poucher stands on 1 foot to avoid the insane heat, eating the scraps of the ship. The oucher pouncher needs no water, so it doesnt need hydration. Its body is also meant to withstand any type of pressure, for 90x earths pressure would surely crush it normally. \n\nPluto:\nPluto is made up of all types of ice. water, dry, though mainly methane. So drinking, again, is out of the picture. They might beable you suck moisture though. The sun is to far away for solar energy, so you can slash out all photosynthesis.\nThe appearence:\nPlutonian zittsles are almost small ice chunks with legs. They are able to last in temperatures in the climates back in the far end of the solar system. In the morning, they do whatever they can to stay cold, for they feel that -234C is almost the exact same as 103F for us. At night, they really get going. They send waves to eachother to communicate while the atmosphere is still up. When they really are energetic, they can spring in the air up to 30 feet. They use tiny mouths under them to suck moisture from the ice. They think that pluto is the only place for life; Everywhere else is to hot. \n\nTitan:\nTitan is the only moon that we know of that can support life. Its atmosphere is composed of mainly nitrogen, similar to ours. So it does have a green house effect. The ground is covered with ice, so they have to eat that for water. Also, they would need to keep warm, since although its not extremem temperatures, its really cold.\n\nThe appearence:\nBear-like Stovebellies are creatures living on titan. To keep warm, they have several features. They have a huge HUGE fur coat. The eat ice for moisture and to cool the ground the stand on. They also have a unique adaptaion to beath fire and fart out heat to go soaring. Salafishes, amphibious organisms, share a mutalion relation ship with stovebellies. They clear out ice blocks and act almost as dentistds for st

As above, the water, atmostpheric pressure, and temperature aren't concducive to human life. But there's another issue: response time. Right now, we have the technology to build a station on Mars. But if something went wrong, it would take us two or three years to get a repairman there!\n\nBecause it takes so long to get there, any settlement on Mars would have to be COMPLETELY self-sustaining, and that's what's really holding us up. (We couldn't even keep the International Space Station going as long as it should have).

Lotsa problems : \n\nTime : it would take like 2 years to get there\n\nHuman body : after 1 month in space, the human body has troubles with its bones because gravity doesn't work anymore, imagine after two years\n\nSpace : sun radiations would be very dangerous\n\nHuman himself/herself : who will volunteer for such a task? Imagine been crammed with 6 other folks in a room no bigger than your average kitchen, they'd probably kill each others before reaching Mars...

may b its possible on mars.....scientist are in reasearch of this.....last year they also find some bones on mars. so may b possible on mars

G'day good question!!\nWell I'm all for space exploration, cos in the very long term it will be important for us to leave this place, scientists believe that places like Mars actually contain water in the soil in the form of Perma Frost, and if it could be released then perhaps we could live there one day. The giant moon of Jupiter ( Europa) is covered in a sheet of ice, what is under the ice is not known, perhaps a type of life form ( now that would create all sorts of questions don't u think?)

not for a long time. nasa doesn't have the funds to do any hugely major projects like it used to. it costs a lot to put stuff into space, and as far as mars is concerned, they're not about to launch

Even though Mars is said to be the most Earth like plant in our solar system. For instance.\n1. Day length (Earth 23h 56min to Mars 24h 37min)\n2. Distance from the sun (Earth 1AU, Mars 1.381AU - 1666AU)\n\nThere are many difference between Earth and Mars that would effect life.\n1. there is no breathable air on mars (made up of 95.3% CO2 and only 0.15% Oxygen). \n2. the gravity of mars in only 38% of Earth, and most likely resulting in muscle deterioration of earth based species (Use it or loss it).\n3. There is also a difference in planet temperature (Mars has be known to have temperatures around -55 degrees Celsius)\n\nThese points among others mean that life on Mars (if possible) would require a different approach then living on Earth.

scientists believe there may be life on Mars because Mars have water in its atmosphere. It may only be a small amount, but could provide life to certain living organisms that need very little water

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.

All we have to do is survive long enough to expand into space. I think if we did that, it would be hard for anything to stamp out all the pockets of humans around. Especially if we could figure out how to not die as individuals.

Yes they did.\n\nBut mars is very far away, and if somone did try to make it out there, they would be at the effect of multiple things:\n\n1.) Solar flares, they would have no protection\n2.) There would be no way to help them if something went wrong out there.\n3.) The astronauts would lose LOTS of bone mass, from the lack of gravity in space.\n4.) to carry enough food and water would need a big spacecraft, thus needing more fuel\n\nAs well as others\n\nBut it aslo has to do with the governments. If it was "Earth" instead of everyone individually, we would have a much better chance.

The idea that life could, or even does, exist on Mars has a long history. In 1877 the Italian astronomer Giovanni Schiaparelli claimed to have seen a planet-wide system of channels (Italian canali). The American astronomer Percival Lowell then popularized these faint lines as canals and held them out as proof of a vast attempt by intelligent beings to irrigate an arid planet. Subsequent spacecraft observations have shown that there are no canals on Mars, and various other alleged proofs of life on the planet have turned out to be equally illusory. The dark areas once thought to be oases are not green, as contrast effects had made them seem to terrestrial observers, and their spectra contain no evidence of organic materials. The seasonal changes in the appearance of these areas are not due to any vegetative cycle, but to seasonal Martian winds blowing sterile sand and dust. Water probably occurs only as ice on and below the surface and as trace amounts of vapour or ice crystals in the Martian atmosphere. The strongest evidence against the presence of life, however, is the thinness of the atmosphere and the fact that the surface of the planet is exposed not only to lethal doses of solar ultraviolet radiation but also to the chemical effects of highly oxidizing substances (such as hydrogen peroxide) produced by photochemistry.\n\nPerhaps the most fundamental and far-reaching result obtained by the Viking landers is that the Martian soil contains no organic material (there is no reason to assume that the two landing sites are not representative of the planet as a whole). Although small amounts of organic molecules are continually being supplied to the surface of Mars by carbonaceous meteoroids, this material is apparently destroyed before it has a chance to accumulate. The results of the soil analysis for organic molecules carried out by the Viking landers provide no evidence for the existence of life.\n\n Answering the question of life on Mars will probably involve...returning [samples] to Earth  \n\nA more difficult question is whether life has ever existed on Mars, given the strong evidence of climatic change and the indications of a previously warmer, thicker atmosphere. Suggestions that structures found in a meteorite discovered in Antarctica, which may have been blasted off the Martian surface, were fossil traces of bacteria-like organisms have since been discounted. However, answering the question of life on Mars will probably involve collecting carefully selected subsurface samples and returning them to Earth for detailed analysis. NASA has proposed a manned expedition to Mars early in the 21st century.
