- MorphicMusic, on 08/06/2008, -0/+3Quades
- Auler, on 08/07/2008, -0/+2Uh, no. I'm just following the Mars lander Twitter, and someone asked them that same question.

They replied.
"@bayol The retro rockets for landing used hydrazine fuel, not perchlorate. 01:26 AM August 05, 2008 from web in reply to bayol "
Also, I don't live in my parents basement. I am 18, and living happily on my own. - vtbarrera, on 02/03/2009, -0/+2Basically no human-like life form could have lived off martian soil, but I'm sure some other life forms may not be as sensitive to perchlorate as we are.
- morphinapg, on 08/07/2008, -1/+2That's one thing I always wonder about science. Why do so many scientists believe that conditions have to be earth-like for life to be possible. Obviously conditions have to be earth-like for humans or human-like beings to live, but who knows what other species may require? Just because life evolved the way it did here on earth doesn't mean it's the only way it's possible.
BTW that would mean the chances of life on another planet are much more likely than previously thought. - GT35R, on 08/09/2008, -0/+1The polar caps on mars are actually made of solid Carbon Dioxide; coupled with the fact that Mars has an atmosphere only a fraction of the pressure of earth's it is understandable why the caps can melt in low temperature. Low pressure reduces melting and vaporization temperature.
If you don't know even that much about mars then you really shouldn't be crying our conspiracy. - xedeon, on 08/07/2008, -0/+1Those were facts ;) if you would take the time and research yourself you will see, instead of sitting on your ass making funnies on the internet..
- inactive, on 08/07/2008, -0/+1It'd be pretty crazy if the Phoenix Mars Lander discovered some human relic on Mars. Mission Control would have a serious mind *****
- zerton, on 08/07/2008, -0/+1agreed! We need roaming landers for accurate samples
- Suricou, on 08/07/2008, -0/+1Not on it's own. It's just the oxidiser. It makes other things more flamable.
- Auler, on 08/07/2008, -0/+1The retro rockets for landing used hydrazine fuel, not perchlorate.
- Suricou, on 08/07/2008, -0/+1Why does everyone assume the soil is uniform? The lander might just have found the martian equivilent of a dried salt lake to sample.
- Zarokima, on 08/07/2008, -0/+0You should be sure of it since there are some here on Earth, as is mentioned in the article
- Pusod, on 08/07/2008, -0/+0i still think the perchlorate came from the landers fuel... it somehow contaminated the equipment. i don't buy their schtick one bit. ummm lets see "perchlorate is a substance found in rocket fuel mixture". doesn't take a rocket scientist to figure that out, but in this this case its kinda ironic dont cha think?
- staystellar, on 08/07/2008, -0/+0um can nasa just make up their minds? LIFE or NO LIFE?!!!
- FurtThePirate, on 08/07/2008, -0/+0Aren't Perchlorate's flammable?
- fatfreddyscat, on 08/07/2008, -0/+0Life Schmife, who cares? Next planet!
- Niallgriff, on 08/07/2008, -0/+0WRONG
we just need a probe that can dig an find a fossil or two. - 5plic3r, on 08/07/2008, -0/+0Also, http://en.wikipedia.org/wiki/Potassium_perchlorate
- m0laria, on 08/07/2008, -0/+0http://en.wikipedia.org/wiki/Ammonium_perchlorate
- kingfoot, on 08/07/2008, -0/+0until humans can set foot on the surface, we willnt know for sure. no matter how smart or advanced the robot is, we wont know until we get intelligence on the surface.
- Sarevok9, on 08/07/2008, -0/+0These comments seriously suck....
- inactive, on 08/07/2008, -0/+0Planet geology, chemistry, solar system evolution, to name a few areas of research that I can think of, are actively studied. Data from Martian soil is much needed for such investigations.
- Auler, on 08/07/2008, -0/+0I don't know, I cant believe anyone. I want to go to Mars myself to find out, anyone want to lend me some cash? I'll pay you back someday.
- Azerael, on 08/07/2008, -0/+0It means we might finally get the bible-beaters to shut the ***** up.
- localzuk, on 08/07/2008, -1/+1Way to think outside the box there...
- Auler, on 08/07/2008, -0/+0I don't think they will really find any form of life, maybe fossils? Ah well... Doesn't mean we can't live there, I want to watch a blue Mars sunset.
- miptex, on 08/07/2008, -0/+0Finding life with a clear seperate origin tells us something about how common life is in the universe. Of course, cross-contamination could also be possible. Which one is more interesting is hard to tell.
- inactive, on 08/07/2008, -0/+0The "life on Mars" question fuels general interest, that's good, but research is needed even if we put the life question apart.
- Auler, on 08/07/2008, -0/+0Sorry? Write something interesting then?
- spyd3rweb, on 08/07/2008, -0/+0The "life on Mars" question fuels funding for Nasa. I really don't see how its important if theres some bacteria on another planet or not.
- Rizzler, on 08/07/2008, -0/+0I'm all for what they're doing, researching and gaining new leads on our universe. But to hear the article say "One possibility, for example, is that the soil samples were contaminated by perchlorates transported from Earth on the lander. Although the fuel of Phoenix itself contains no perchlorates, they were used in the boosters during launch," can only make me question the credibility of the entire project. If it were contaminated from the rockets, who is to say what else hasn't been contaminated? We could be there discovering molecules that we brought with us. I'm just hoping it wasn't contaminated.
- Ne007, on 08/07/2008, -1/+1Do I care if there is life on Mars? No.
We should have colonized Mars and space already with the money spent by NASA. Then we would KNOW that there is life on Mars. - Auler, on 08/07/2008, -0/+0That would be awesome, well.... If you were there to see it while it happen.
- thegrantman, on 08/07/2008, -0/+0Your comment is the only useless one here.
- TheNeptune, on 08/07/2008, -0/+0It's do to how we understand life requiring energy. We apply what we understand to the creation / production of energy that would be vital to survive and water for example is required for photosynthesis, cellular respiration and anaerobiosis (which doesn't require oxygen). So, while not necessarily life like, we look for things like water because water creates an ideal environment for organic compounds to react.
So, while yes you're right perhaps life may exist in some other form in some other place, it's pretty much impossible for us to scientifically comprehend that thought as we have no examples and nothing to reference from. - DeathJux, on 08/07/2008, -0/+0Good luck trying to talk the crazy out of him, guys, it won't work.
- dungar, on 08/07/2008, -0/+0Dear NASA,
your shipment of Fail has arrived - mta3d, on 08/07/2008, -0/+0or send some dirt back to earth for analysis - it cant be that much harder than actually getting those robots up on mars in the first place?
- 0x0000ff, on 08/07/2008, -0/+0oh sweet, I love conspiracy theories! :D

http://daybedcomfortersets.blogspot.com/ - Nanobe, on 08/07/2008, -0/+0The Earth's atmosphere was originally full of carbon dioxide, which is why plants were able to thrive. The plants put all of the oxygen in our atmosphere, which then enabled animals to evolve.
- Suricou, on 08/07/2008, -0/+0One sample. One site. From this we are infering the conditions on the entire planet? Perhaps the lander just happened on a perchlorate deposit. Land somewhere on earth and take a sample, there is a chance you will dig up pure salt from a dried-up salt lake. More samples are needed from a much wider area.
- jambla, on 08/07/2008, -1/+1So basically what your saying is that you; a digg commenter, a 38 year old guy living in his parents basement, a guy who has never had a girl friend is smarter than ummm... NASA. Yup I'm stupider for having read your comment.
- ozodin, on 08/07/2008, -0/+0Puff, puff, pass. Don't be greedy!
- thegrantman, on 08/07/2008, -0/+0Why do we continue to insist looking for life based on our model? Life can't exist on this planet,there's too much this or not enough that.Absolute crap.We have no idea what defines life; the possibilties are endless.
- arijit57, on 08/07/2008, -0/+0Good Life without Oxygen.......
- Lyk4n, on 08/07/2008, -0/+0Oh wow, this one is a doosy!
- ChstrCopperpot, on 08/07/2008, -0/+0It's been said ammonia could work just as well as water with the right cellular biology. Lots of ammonia out there...
- jamesdew, on 08/07/2008, -0/+0 - how do you know how big mars is ffs
- Reference please?
- Maybe it isn't made of water? Ever think of that?
- Maybe it is one hell of an atmousphere
- Haha after reading this one I wish I hadn't even bothered to write the other comments, you're so funnie -
