How NASA's Curiosity rover could 'discover' Teflon on Mars (+video)

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.

The Mars rover has gone above and beyond what nasa ever hoped for - and it seems like we could get even more.

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.

NASA scientists discussed the contamination concern and a new Mars landing plan for the car-size Curiosity rover in a teleconference with reporters today (June 11). The contamination issue, they said, concerns the rover's drill.

When Curiosity ultimately bores into a Martian rock, small amounts of Teflon and other contaminants from the drill will likely seep into the sample, NASA officials said. These introduced materials may make it tougher for the Curiosity team to search for organic carbon — the building blocks of life as we know it here on Earth — on the Red Planet.

While researchers are still working to get a handle on the problem, they don't think it will significantly hinder the Curiosity rover or its $2.5 billion mission, which is officially known as the Mars Science Laboratory (MSL).

Right now, the overall sense on the mission team is that "it's not a serious problem, because we see so many potential ways to work around this that we could use," Curiosity lead scientist John Grotzinger, of Caltech in Pasadena, told reporters today. [Curiosity - The SUV of Mars Rovers]
