Nasa Mars Rover Makes Second 'Accidental' Marking On Red Planet

Following news that Nasa's $800 million Mars Rover had accidently drawn a penis on the surface of the Red Planet, a fresh image released by the space agency on Wednesday morning has revealed a second unexpected mark - the name of ‘Ed Balls’.

A Nasa spokesperson told the HuffPost UK that the daubing of the name of the Shadow Chancellor of the Exchequer for Great Britain and Northern Ireland is "certainly one of the more unusual events in the history of human space exploration" but he remained adamant the tracks were made at random by the rover as it searched for signs of ancient water.
