While we're joking around, I minus well:
No, it is all that remains of a once great statue of a Martian monarch, which once read in Martian something to the effect of "look upon my mightiest of works, and despair!", until all but the head had been eroded way.
Contaminate it with what? An invasive bacterial species that would be totally devastating to Mars' unique and thriving ecosystem?So, my question is, is it really wise to send humans to Mars when they could potentially contaminate the environment?
Unless you're concerned about awakening the hidden Monsters of the Id, probably not.If there is a chance we could discover life that once existed on Mars, wouldn't it be better to continue to explore the planet with only robots?
Any sort of finding ambiguous enough that it could possibly be terrestrial in origin is not worth loosing sleep over. Scientists may find it very exciting to discover fossilized microbial life in an ancient Martian desert, but the entire rest of the human race won't even find it in them to yawn with boredom.Previously, scientists suspected that Mars once had flowing water. But, they didn't know how much or for how long. Science now confirms that Mars had an ocean that covered 20% of its surface for billions of years.

How is sending humans to Mars any different than humans being on Earth and contaminating this planet?
My statement had nothing to do with the environment on Mars. It has to do with the outside chance that we could discover there was once some kind of life on Mars. If humans bring bacteria and microbes with them there, it can cast a doubt on what we might find there one day.

I don't know that I agree with you. I am not a scientist, but I would find it pretty exiting if we were able to find fossilized microbial life on Mars. It would be the fist time we discovered that any kind of life evolved independently on another celestial body.
That is the issue I'm a little confused by. How did the water "leave Mars?" The article seems to indicate that Mars lost its atmosphere and gravity, so stuff floated away. How exactly does something like that happen? Perhaps I'm misunderstanding something.

It doesn't exactly have a very strong gravitational pull, so the atmosphere probably slowly evaporated over time.
From the article:
Although the Martian surface is now cold and dry, there is plenty of evidence suggesting that rivers, lakes and seas covered the Red Planet billions of years ago.
From the article:
By studying the current ratio of deuterium to hydrogen in Martian water, researchers suggested they could estimate how much total water the Red Planet used to have.
This is hardly a confirmation that Mars had a vast ocean. Many bodies in the Solar system have a hemispherical asymmetry—including the Moon, and the Moon didn't have a huge ocean filling the lower elevations.
Would that evidence include alleged river channels that run both uphill as well as down, and have no exit basins?From the article:

Suppose Mars had a high level of deuterium for some other reason? It is only assumption that Mars must have had water in the same ratios as Earth.From the article:
