NASA's Mars rovers have seemingly drawn a large penis on the famous Red Planet by accident.

Launched nine years ago at a cost of $800 million (£520m), two Mars Exploration Rovers named Spirit and Opportunity were sent to Mars in the hope of finding signs of water erosion and even life.



The twin exploration vehicles have so far travelled more than 10km across the planet.

It is believed that the penis mistakenly surfaced from the rovers spinning in circles to get a feel for the terrain.

The image, which was shared on Reddit earlier this morning (April 24), proved so popular that it caused the NASA website to crash.
