21. The Opportunity Rover found what looks like a bunny rabbit.
While the Opportunity rover never discovered life on Mars, it did find an animal-shaped object. In March 2004, roughly two months after it was put on Mars, the rover used its panorama function to capture a “bunny rabbit” on its surface. The object was soft, as it moved slightly in the weak winds of Mars’ atmosphere.
The bunny ears were yellow in color and measured about 2 inches long. Researchers monitoring Opportunity’s images believed the object originated on the rover and somehow dropped onto Mars as it was traveling. The item has never officially been identified, but many think it was an adhesive used for aerospace applications called Kapton tape.
