In 2003, Nasa launched two rovers to Mars in search of evidence of line on Mars- one of them is the Spirit Rover.

Spirit arrives Mars on Jan 24, 2004 tasked with tracing water, learning about Mars current and past climate, and mapping out the red planet's terrain.

Despite its expected ninety days warranty, Spirit did not stop working until March 22, 2010 when it was stuck in a sand trap.
