‘Out of control’ Mars Rover building sandcastles

NASA scientists admit they’ve lost control over Curiosity since the Rover started to use its $50million robotic arm to skim pebbles across an ancient Martian sea.
Earlier this week Curiosity deployed a titanium scoop to make a precision line of sandcastles. It then reversed 20 metres, sped towards them and flattened them. Communication is now difficult. Control messages are returned marked ‘I am on annual leave. Please direct any queries to my colleagues Spirit or Opportunity’..
