The first person to find the location where the NASA Curiosity rover was filmed and staged WINS A PRIZE

The answer lies in Google earth.

I won't tell you where it was filmed.

But heres an "official Mars" pic from NASA which you can use as guidance to pin point the exact location (texture/scenery and everything) on Earth where it was filmed.

It has to be a desert, so that narrows down places. But where exactly, its for you to find.

The first person to find the location where the NASA Curiosity rover was filmed and staged WINS A MAGNIFICENT PRIZE.

Happy Hunting!
