Simple organic molecules could be present just a few inches below the soil on the surface of Mars.
In August NASA's ambitious car-sized rover, Curiosity, will touch down and begin investigating the Red Planet to determine if Mars was ever a place where life could have developed. Researchers believe that simple organic molecules such as formaldehyde could exist just a few inches below the surface, if this turns out to be true then it greatly increases the chance that Curiosity will find something.
"Right now the challenge is that past Martian landers haven't seen any organic material whatsoever," said lead author Alexander Pavlov. "We know that organic molecules have to be there, but we can't find any of them in the soil."
"Researchers say that evidence of ancient life on Mars could take the form of simple organic molecules lying just beneath the Red Planet's surface, and that it could be detectable by NASA's newest rover, which is scheduled to touch down on the planet next month."
