Humans traveling to Mars, is it worth it, based on the details below?

I think if the astronauts know all this.. and are still willing to, they may as they please.. but in my opinion it's not worth it.. they should jsut keep sending satelite's up there and learn more information about mars and other information they want.

I will do it to satisfy my curiosity. A free trip in the space to discover other inhabited planets and galaxies is a dream come true. It is an occassion not to miss out but i would not go for ever because there can't be no better place than our home. I will return back to earth after the trip to my home sweet home.

Lot's of people will be rich in this world, but few will see this world from outer space.  When I think back to the quotes of the astronauts, they all spoke with awe of their experiences.  The event of getting outside of this world is/would be life changing.  I think it would change each person's perspective of the world.  I would choose the space trip with no regrets.

Many experiments that have help us advance in medicine are conducted in space. Our planet can be in danger of asteroids plunging into us, and can result in life on earth being destroyed, and by expolring space, we can find out and save us, so yes, it is worth it. And it's fun!

Short answer:\n\nUnmanned space exploration is more cost effective, efficient, and lower risk. We can always build new robots, and we can send them over longer distances than people (at least initially).\n\nManned space exploration would have a better chance to capture public support. A human mind in control of a space mission might see or intuit things a computer guided sensor might not, and it might react creatively in an emergency. Ultimately, we'll place more value on manned spaceflight. We've already put robots on Mars, but the first human on Mars will be a much bigger deal. Sending humans through space safely seems to be one of the goals of space exploration.

You are reffering to the Mars Exploration Rovers.  There is also a probe on it's way to Mars to see if it had any long standing bodies of water.

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...

Living on Mars is theoretically possible, but the cost of sustaining life there is prohibitive.  The greatest problem with sustaining life on Mars is that once humans got used to the lesser amount of gravity, they would not be able to return to earth as the organs would not be able to operate under the gravity on earth.\n\nAnd judgement day?  If you mean the day when you die, moving to Mars won't stop you from dying.  And if you mean a theoretical day when all of the humans will be judged at the same time, I doubt that moving to Mars is going to protect you from that, if you believe in that sort of thing.

MARS... quite possible

In theory it is absolutely possible. In reality, we haven't advanced science to the point where we can inhabit other planets. Currently there are plans to build an elevator that will allow people to enter space without spending months and months training their bodies to withstand the G's when exiting the atmosphere.\n\nThe current step to living on other planets is building a space station large enough to house multiple families, a small city or even refuel a ship. Currently right now travelling to Mars would take years and years. We would need a higher powered engine that uses less fuel and provides more thrust.

Hi there!  I'm a physics and astronomy student, so, while I'm not the authority on the subject, I can tell you what my current understanding is:\n\nIt really all comes down to cost in my opinion.  We aren't sending astronauts to Mars primarily because it would cost a lot to get them there with current technologies and it would still take a while for the trip (it took about 7 months for the Mars rovers to get there).\n\nSome people also think it is unsafe because we haven't sent humans out nearly that far yet.  Messages would also take at least 8 minuets to get a response (I think Mars is about 4 light minuets away so it would take as long to transmit a signal to Earth and just as long for the response to get back).  That's kind of a pain but not a big problem in my mind.\n\nAs for sending probes further out, this is indirectly related to cost.  We are still only able to move so fast.  You can blame this on reduced funding for NASA if you like (or closed minded scientists perhaps).  \n\nWe have sent a few probes out to explore the outer planets of our own solar system but we can't expect to be exploring other stars and solar systems anytime soon because even the next closest star system is about 4.3 light years away.  If we could travel at the speed of light (which we definitely could not with current technology) it would take 4.3 years to get there.  (Using the relationship for Mars from earlier I'd guess that this means it would take oh...162,540 years (really rough estimate assuming I did the math correctly) with our current abilities, so sending humans would be silly since we rarely make it past 100).  This is connected to funding because, in theory, if we had more money we could come up with and actually use better ideas for space exploration, including faster means of travel.\n\nFinally, we can explore "visually".  We can collect different types of light (like visual light, infrared, x-ray, and ultra violet) and learn a lot about our universe that way.  Most of what we know about our universe comes from local collection and interpretation of this (like with Hubble).  This field is progressing at a reasonable rate as we developer better equipment for viewing very distant things in great detail.  It could also benefit from increased funding though.\n\nIn retrospect, I suppose that money might be the root of the issue, but until we figure out how to jet through space more quickly, so is time.

sorry no answer.  but i was wondering?  How is Mars this time of year?

Humans will probably live on Mars at some point, though it would probably be only temporary.  Now let's look at the problems.\nThe biggest problem would be making Mars a suitable environment for human life.  Terraforming the planet to give it a similar atmosphere as Earth would take thousands of years, if not longer.  The other option would be to build colonies.  And even then there's the question of what to do about gravity.  Because the gravity on Mars is less than that of Earth humans would have a difficult time maintaining muscle mass and bone density.  So, some sort of solution would need to be found.\nNext, let's face it, Mars is terribly far away and has little to offer, except maybe some frozen water.  And being so far away from Earth would probably be very problematic.  It is much more likely that in the future, if humans are to live in space, they'll live in self-sustained space colonies orbiting the Earth.

Yes - we learnt that there was no cheese in the moon or that there were no green men in mars.\n\nJokes apart - improvements in space travel - hs helped in improving sea going vehicles (submarines etc) also treatment of paraliysed people, also treatment of muscle atrophied etc...\n\nalso the satelite age heraled the ability for us all to better predict weather changes and also determine where the next oil deposit could well be...etc\n\nso you need to look at it all in the context of the benefits of space travel...so yes its important...\n\nand the money spent is well spent

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.

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.
