A conspiracy theory fast gaining traction online makes the astounding claim that NASA's Curiosity and Opportunity rovers never traveled to Mars and that the images of the Martian environment being uploaded to NASA websites were actually taken on a remote island called Devon Island in Canada, the largest uninhabited island on Earth.
According to the rumors making the rounds in the conspiracy theory blogosphere, the pictures being uploaded regularly to NASA's websites and palmed off as images of the Martian environment are fake images taken on Devon Island in Canada where NASA has set up a landscape identical with the "Martian landscape" we see on photos NASA scientists upload to NASA websites.
Conspiracy theorists claim that the rovers never traveled out to space, let alone land on Mars. Rovers Opportunity and Curiosity are being kept in storage in one of NASA's facilities. Meanwhile, the agency has deployed two smaller versions of the rovers -- "baby rovers" -- on Devon Island in Canada.
NASA maintains permanent bases on Devon Island where NASA personnel dressed in mock astronaut suits play around with "baby rovers" fitted with cameras. Conspiracy theorists note that the terrain of the island bears a striking resemblance to the images of the "Martian environment" that NASA uploads to its websites. This makes the island an ideal location on Earth for NASA to stage make-believe Martian environment photo shoots.
