Teflon from the drill on NASA's Curiosity rover could contaminate Martian soil, say scientists, creating misleading evidence of an ancient alien civilization that had developed nonstick cookware.


An unexpected contamination problem has cropped up for NASA's next Mars rover, but scientists are confident the huge robot will still be able to complete its mission after it lands on the Red Planet in August.
