As a  mission found old living water tracks  on mars how much intrested for us?

The discovery of dry riverbeds on Mars means that there was once flowing water on Mars, which is VERY interesting. Not only for knowledge of the past conditions on Mars but because that water may till be there. Recent measurements say there is a lot of frozen water just below the surface.

leave yes, but not forever.  then i could come back & visit & see how much space debris & space trash is floating in our upper stratosphere.  then i could appreciate how untrash the new place looks.\n\n\nby the way, do U really have monkey feet?

They are going to try and explore the possibilities of living on Mars in the future due to the fact that they believe the Earth will eventually become unlivable due to the warming of the planet. It probably won't happen in our lifetime but Man will pollute the Earth, the air, and the water so much that we will not be able to survive. The hole in the ozone layer is becoming a major problem.

I do not know all of them, but there were at least a half dozen Mariner, Viking, and Soviet probes that were sent to Mars in the 70's.  There have been three landings.  The Sojourner rover landed in 1997; and the Spirit and Opportunity rovers landed in 2004 and are still going strong.

It depends on your goal. From your extended question it sounds as if we should be terra-farming extra solar planets. i'm not sure we'll be at that point in another 1000 years, even if we put our minds to it.\n\nOne could argue quite reasonably that our CURRENT space program hasnt achieved much. the space shuttle never accomplished a fraction of what it was designed to do. The space station just kinda goes around and around. \n\nTo type out the statement  "All our efforts so far has yielded no result" on your hyper-fast micro computer connected to a planetary data network is a bit short sighted. Nearly 50 years of space exploration has produced a wealth of technological advancements. \n\nYou also have a few billion years to worry about a place to go when the sun and earth die out. Maybe less for the earth, that's probably addressed in another question.

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.

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.

well let me tell you the first natural resorce we will run out of...it is not oil or natual gas it will be water...the most imporant...at the currant rate of polulation increase we will have to use every last drop of fresh water to surive in about 120 years...of course we can distill sea water but that will only delay the stituation...we are not going to find any more water on this planet so space is the nest best altenative...that is quiet honestly why we should keep space exploration alive...the only thing i would like to see is corpations and indivuals do it as well...\n\ntruthfully there will always be poor...sad to say...but hey look at it this way...did you get a internet connection...did you go out to eat this week...do you have cable tv...and i would be willing to bet that you have a computer as well...you could spent the money on some charity instead...it is not alway the goverment that should fix our problems...sometime we have to do it

Well, you are correct in that sittin' around will end in our collective lifes' destruction.  And attempts at proving life beyond Earth are ongoing.  Many of the missions to Mars are currently trying to prove that (among other things).  SETI is also an attempt to see or hear if anything is out there.  But that's a shot in the dark (har, har, de har har).\n\nThere are some significant steps being made to make spacecraft that can go "fast".  VASMIR (plasma rocket) among other things.\n\nThe two technologies that will drive us into the next level of abilities are quantum and nano technology.  Those will have significant impact on everything we build and contemplate.\n\nEventually our sun will get hotter, that could boil off our oceans (way before the sun bloats).  The Earths core could also cool enough that our magnetic field dissappears.  This would cause our atomosphere to slowly whisp away.\n\nBeing able to live in more hostile environments with nearly 100% recycling ability is our greatest challenge.  WIth that, we can start making our way out of this solar system and on to the next.\n\nWrite me for more discussion.  Fa shizzle.

It's not so much the Martian life that might have been there, but rather, the Earthly life that we could send there in the event of, oh say, an anticipated global-killer meteor hit here until everything cooled down and Earthly re-seeding could begin. Aside from that, we humans, we explore.

That is so funny that you asked this. My kids and I were watching the news last night and there was the discussion of having the ability to land on Mars. They have discovered certain bacterias on Mars. The statement made was that the men and women selected to go to Mars would do so with the knowledge that they would never return to earth. We could not risk them bringing back a bacteria or substance that could grow and cause disease. My girls asked me the same question you did. Just last night! \n\n"Mommy, would you go knowing you'd never see us again?"\n\nWe all have our passions. Look at our different jobs and you can see what it is that drives us to work and provide not only for our family but for our self worth. I teach school cause for some strange reason I like to pass on knowledge. I'm sure there are people that want to pass on knowledge to the point of discovering it so that others can benefit from it. So much so that they would move to said distant planet as a pioneer. I hope I'm not being selfish when I say that I could not. My place is here. As I said, we all have our passions. Mine are directed towards so many responsibilities here that I could not desert them to do such a noble deed. Those that do........those that sacrifice all they have or could have are some of the greatest heros we'll ever know. So instead.......I'll teach about these people and make their findings worthwhile by passing on the knowledge of their discoveries. Maybe that could be my part. *shrugs*

In addition to the oxygen, water, issues previously discussed, the surface is under constant attack by radiation and high energy particles due to the lack of a sufficient atmosphere.  We would have some mutated DNA after too long on the surface.  That's not too good.

Actually Rolling Stones Magazine just wrote an article on tthis.  I'd go to your library and read it because it was really interesting.  According to the magazine, the Bush administration is trying to send a shuttle to Mars to do some necessary research on the planet to figure out if it is sustainable.  As far as water goes (someone mentioned it before me) they are saying that the astronauts will have some sort of device that turns urine into drinkable water. \n\nThere also saying that it will take 6 months to get to Mars.  Also, if they were to launch several people into space, they wouldn't be able to do it all at once.  Rather, they would launch separate parts and connect in outerspace.\n \nThe article said that they want to send to astronauts out around 2020 to do the initial investigation.\nCheck out the article...its really good.

Okay, we are finding and discovering new forms of life all the time with new technology.  There are new marine animals found with the deeper we are able to explore.  Animals, bacterias, all forms of life are mutating and popping up all over the world.  On mars, they've discovered water on the planet and plant life under the surface of this water.  \nOkay, so it's not Star Trek yet.  We haven't communicated with alien beings...that we know of.  But that's not specifically what you asked now, is it?

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?)

First we would need a secure dome to live in, to retain the air we need to breathe, and a way of removing the carbon-dioxide from it - plants are good at this - and we would need to keep the dome heated, as Mars' warmest day is colder than Earths' coldest, I remember reading.  We would have to use hydroponics to grow food, and meat would be a luxury of the past. Expect an awful bland diet for years. Gravity is something like 2/3rds of ours, so our activity in the dome would be pretty easy, but you'd need to learn how to sprint again, if you were into running, and imagine the hundred metres being run in not just under ten seconds, but perhaps six!  Mars would actually be a great place for the elderly to retire to - less fall injuries, less heart stress.  Children born on Mars would grow very tall, perhaps damaging them - tall has its' downsides for humans, particularly back and circulatory troubles.  Nuclear bombs detonated out on the Martian plains would generate enough heat to release the water scientists tend to agree is frozen in there, in the soil and rock, and if large panels of black material were laid out, their albedo would catch and retain heat.  We need a thick, oxygen rich atmosphere.  Mars' is very thin, and with little oxygen.  Such 'Terra-forming' (making Earth-like) would be a huge undertaking.\n  So there you are, stuck in your dome, bored, hurt yourself badly from running at 40mph, vegetarian, with nine-foot tall kids, and Grandpa is 168.  Perhaps death would be preferable...

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
