Water on Mars?!

Mars once had a thicker atmosphere like Earth did, which might helped create a viable environment for life. Now there's little atmosphere left - the sun's radiation probably kills off any life there. Humans would get cancer trying to live on Mars without some kind of protection.

Also, the equator of Mars can reach up to around plus 20 degrees celsius. However, you won't find liquid water there, because liquid water is highly unstable in Mars' environment compared to Earth's.

They way that I understood it was that all the terrestrial planets had extremely thick atmospheres (kind of like Venus does today) of an extremely toxic composition, but solar bursts from the sun scorched away their initial atmosphere's. Because Mercury and Mars were too small, and not as geologically active, they weren't able to regenerate their atmospheres, thus most of Mar's water evaporated save for that which was frozen in the crust.

Hopefully once we screw up this planet we have mars as a backup.

we already have screwed up the planet

we must hurry!

Last one to Mars is a cold tubeworm!

I completely agree because the thought of earth and everyone on it dying from global warming eventually is kind of scary.

No matter what we do to earth it will never be as bad as mars...if we developed the technology to live on mars we would have developed to technology to live on a ****ed up earth.

Ooh, water on Mars, yes. Ice is water too, of course. Too bad water isn't the only thing life needs in order to evolve, adapt and thrive. Concerning life, Earth took almost 2 billion years to make life sustainable. I don't think we have that patience nor time with what we are about to go through.

I read this book from the library:

"The Life and Death of Planet Earth"

The Life and Death of Planet Earth

http://books.google.com/books?id=WVb6Uu9aluYC&dq=The+Life+and+Death+of+Planet+Earth&pg=PP1&ots=QStTifa7p5&sig=8YcOdtycMtNneIntxaOSkwY3Fuw&hl=en&sa=X&oi=book_result&resnum=1&ct=result#PPA22,M1

"They deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down." —Publishers Weekly Science has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of our planet. Peter D. Ward and Donald Brownlee, a geologist and an astronomer respectively, are in the vanguard of the new field of astrobiology. Combining their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of how stars and solar systems grow and change throughout their own life cycles, the authors tell the story of the second half of Earth's life. In this masterful melding of groundbreaking research and captivating, eloquent science writing, Ward and Brownlee provide a comprehensive portrait of Earth's life cycle that allows us to understand and appreciate how the planet sustains itself today, and offers us a glimpse of our place in the cosmic order.

This book was about how Earth came about, how lucky it was at the time to get to where we are today (ie. water, the right 'tilt' of Earth's axis, distance from the Sun, etc.) It also brings up how the Earth may become unsustainable for life in less than half a billion years from now. Check out this book; you'll learn something from it.

It says Mars along time ago may have used to be Earth, but Mars now was a clear picture of a future Earth if the rate of vital things decline continues to move at its pace right now.

It also talks about moving to another planet and how difficult it would be to even try to move to Mars. Even according to the link AznGreen posted that it took almost a quarter of a billion to just send a little machine to check up on the planet's surface. Imagine moving willing amounts of people to Mars, let alone how long of travel it would be (a couple of months), the new changes on Mars that require people to develop ways of surviving (lesser sunlight, thin atmosphere that doesn't protect from UV rays, no oxygen, losing bone mass because of less gravity, and other health problems) and the transport of necessities back and forth from Earth to here. It's going to take money... ALOT of money.

It summarized that we may have to deal with Earth no matter what happens. Finding another planet sustainable like Earth is near impossible to to find. If Mars is the answer... let's just hope money wouldn't be the main issue trying to move out.
