Mars rover already worked more than expected


The mars rover was sent to mars for a 90 day mission five years ago and ‘The Spirit and its sister’ rovers have already spend more than expected time on Mars, exploring the various factors of the planet and the only wear and tear found on the rover is on the wheels and the rover has not been accepting signals from earth.

The researchers believe that the robot vehicle will start running again smoothly and the scientists are optimistic about the vehicle.
