Mars rover finds "puddles" on the planet's surface

 

A new analysis of pictures taken by the exploration rover Opportunity reveals what appear to be small ponds of liquid water on the surface of Mars.

 

The report identifies specific spots that appear to have contained liquid water two years ago, when Opportunity was exploring a crater called Endurance. It is a highly controversial claim, as many scientists believe that liquid water cannot exist on the surface of Mars today because of the planet’s thin atmosphere.

 

If confirmed, the existence of such ponds would significantly boost the odds that living organisms could survive on or near the surface of Mars, says physicist Ron Levin, the report's lead author, who works in advanced image processing at the aerospace company Lockheed Martin in Arizona.

 

Along with fellow Lockheed engineer Daniel Lyddy, Levin used images from the Jet Propulsion Laboratory's website. The resulting stereoscopic reconstructions, made from paired images from the Opportunity rover's twin cameras, show bluish features that look perfectly flat. The surfaces are so smooth that the computer could not find any surface details within those areas to match up between the two images.

 

The imaging shows that the areas occupy the lowest parts of the terrain. They also appear transparent: some features, which Levin says may be submerged rocks or pebbles, can be seen below the plane of the smooth surface.

Smooth surface

 

The smoothness and transparency of the features could suggest either water or very clear ice, Levin says.

 

"The surface is incredibly smooth, and the edges are in a plane and all at the same altitude," he says. "If they were ice or some other material, they'd show wear and tear over the surface, there would be rubble or sand or something."

 

His report was presented at a conference of the Institute of Electrical and Electronics Engineers, and will be published later this year in the institute's proceedings.

 

No signs of liquid water have been observed directly from cameras on the surface before. Reports last year pointed to the existence of gullies on crater walls where water appears to have flowed in the last few years, as shown in images taken from orbit, but those are short-lived flows, which are thought to have frozen over almost immediately.

Speedy evaporation?

 

Levin and other reasearchers, including JPL's Michael Hecht, have published calculations showing the possibility of "micro-environments" where water could linger, but the idea remains controversial.

 

“The temperatures get plenty warm enough, but the Mars atmosphere is essentially a vacuum," says Phil Christensen of Arizona State University, developer of the Mars rovers' mini-Thermal Emission Spectrometers. That means any water or ice exposed on the surface evaporates or sublimes away almost instantly, he says.

 

But, he adds, "it is theoretically possible to get liquid water within soil, or under other very special conditions". The question is just how special those conditions need to be, and whether they ever really are found on Mars today.

 

If there were absolutely no wind, says Christensen, you might build up a stagnant layer of vapour above a liquid surface, preventing it from evaporating too fast. “The problem is, there are winds on Mars… In the real world, I think it's virtually impossible," he told New Scientist.

Simple test

 

Levin disagrees. He says his analysis shows that there can be wind-free environments at certain times of day in certain protected locations. He thinks that could apply to these small depressions inside the sheltered bowl of Endurance crater, at midday in the Martian summer.

 

He adds that highly briny water, as is probably found on Mars, could be stable even at much lower temperatures.

 

Although the rover is now miles away from this site, Levin proposes a simple test that would prove the presence of liquid if similar features are found: use the rover's drill on the surface of the flat area. If it is ice, or any solid material, the drill will leave unmistakable markings, but if it is liquid there should be no trace of the drill's activity.

 

Levin’s father Gilbert was principal investigator of an experiment on the Viking Mars lander, which found evidence for life on the planet, although negative results from a separate test for organic materials led most scientists to doubt the evidence for biology.

You know what this menas right.

 

Water allows life to exisist... in life there is love.. with love comes MAD FUCKING BJs.. and mouthies make me cum

 

I want to be the first white guy to get his dick sucked on MARS.

 

 

i get sloppy seconds on the alien broad. :D

ALIEN??? No you fucking sickos.

I'm talking about bringing a white lady up there to suck my dick. I just want a regular

BJ from a regular lady. If nasa even allows ladies to touch thier whips.

 

 

so you're telling me that if martians were really a race of hot blonde bimbos with the best bodies in the galaxy, you wouldn't tap that ass?!

 

if she looks like this, of course i wouldn't hit it...

so i saw this documentary about how their is ice underneath the ground, muhc like how earth has/hd ice underneath the soil, and that if scientists create global warming in mars, this would cause the ice to melt, inturn bringing it to the surface and creating "life".

 

Yeah, I saw Total Recall too.

only God can "create life"

 

 

 

...but youre right....heres a chunk of mars.....

i wonder how they would create global warming there??....send over some SUV's?

 

send me and my explorer over there to do some damage! WHOOOOOOOOOOOOOT
