Your mind wanders when you're flying 220 miles above Earth in the International Space Station.
From time to time it wanders all the way to Mars.
ISS Astronaut Luca Parmitano was flying above Chile yesterday when he noticed a farm in the desert that looked like concept images of a Martian colony on the Red Planet. And that got him wondering...
The picture is actually of a lithium salt production facility in Chile which, if you're interested, you can learn more about here.
