Why Curiosity rover is likely to find "Martians"

(LiveScience) With the rover Curiosity now safely on Mars, the world will be seeing lots of video in the coming months and years from the planet's surface.

The six-legged, nuclear-powered $2 billion robot has already sent back images of Gale Crater where it landed, and it's soon on its way toward a 3-mile-high mountain nearby. Scientists -- and indeed the entire world -- are watching with bated breath to see what Curiosity can find as it spends the next two years digging, sampling, probing, and analyzing on the Red Planet's rocky surface.

Many will also be looking for evidence of life on Mars, and Curiosity may provide it -- even if it's not there. NASA footage has long been fodder for UFO buffs and conspiracy theorists who comb through countless photos and hours of video looking for evidence of alien life (or evidence that NASA is covering up evidence of extraterrestrials).

Indeed, NASA images have previously been claimed to show evidence of Martian life.

A man named Richard Hoagland claimed that 1976 photographs of the Cydonia region of Mars showed a human-like face. The so-called "Face on Mars" rose to international fame as Hoagland waxed speculatively about the significance of the stunning find: Was it a sign for us from extraterrestrials? Where were the builders of this magnificent monument? On April 5, 1998, the Mars Global Surveyor took photographs of the same region in far higher resolution than was possible in 1976. The new images clearly showed an area heavily eroded, and that the "face" was simply the result of low image quality, the brain's tendency to see human forms and faces, and tricks of light and shadow.

In 2001 an amateur astronomer found what he believed to be a mysterious rectangular structure on the surface of Mars while looking at a program called Google Mars featuring satellite images of the planet. Professional astronomers explained that it was in fact an artifact created by the interference of cosmic rays; the anomalous shape was created in the camera, not on the surface of Mars.

Photos of the surface of Mars taken by the NASA robot Spirit in 2008 were said to show a humanlike figure. Several Internet sites posted the image and suggested the figure could be alive, sparking speculation and controversy. The real explanation, according to astronomer Phil Plait of the Bad Astronomy website, is that "The rock on Mars is actually just a few inches high and a few yards from the camera. A few million years of Martian winds sculpted it into an odd shape, which happens to look like, well, a Bigfoot!"

Then in 2010 a team of psychics led by Courtney Brown, a researcher at Emory University, claimed to have found evidence not only of life on Mars in NASA photos, but also a large industrial dome and a plume of waste coming from it. In a video presentation titled "Evidence of Artificiality on Mars," Brown claimed to have found "a very large dome that is highly reflective, it looks like it's made of some sort of resin material." Needless to say, no other evidence of an alien dome has ever been found.

History and human psychology tell us that sooner or later, one or more of the thousands of images beaming to us from Curiosity 352 million miles away will contain some glitch, anomaly, or trick of light that will be interpreted by someone as evidence of Martians. Of course it's possible that the rover will find real, actual evidence of life on Mars -- but it probably won't be in the form of alien bases.

hmmmm 'Nasa' the onlyy company in the last 40 years to hav gone backwards as technology has advanced, what a waste of space! excuse the pun. There are countless images of evidence of a civilisation on mars that you can even download form the 'ESA' website yourself and look at, Hale crater for one. Nasa will never admit to anything , if a ufo landed on the whitehouse lawn they will still say its a weather balloon or swamp gas. Noval53 is spot on here, we are looked at as such a primitive race who will eventually destroy themselves and the planet along with it. I find it incredible how people who have lived on this planet for a small number of years come to a conclusion that we are alone in the universe when they have barely left their town let alone our planet. ".You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe"

[Noval53]

It's highly likely that many civilizations exist throughout the galaxy that are far more advanced than we. We are far out on one finger of the galaxy in the rather rural boonies. Travelers from the great civilizations fly by, stop for a few laughs, and then move on to much more advanced and interesting places. With our noses pointed to the sky, we arrogantly stand on a rock, "that we can't leave", and pronounce that "We know the Universe". Future "knowing" generations will look back and wonder at how our vast ignorance could lead to such pompous arrogance.

For all the naysayers, for all the terroists, for all the haters detrcters, Chinese, Russians, Arabs,... and other hateful cultures,,,,,We put a robot on mars we the americans us, the most advanced country in the world, the one you guys hate becse you cant keep up with us. Well we did it while you guys are killing each other, repressing your citizens, mudering your people in polution, We did it NASA ... So to NASA.. Congradultions, you did one hellava job...I am proud of you!!!! NASA, not the congress, senate, president, or other politicians...The egg heasds, the scientists the workers, the fabricators the computer programers... and all the others from the janitors to the leaders....
