The Spirit rover attacked Mars again in 2005 September. What might look, above, like a military attack, though, was once again just a scientific one - Spirit was instructed to closely inspect some interesting rocks near the summit of Husband Hill .

The Spirit rover , and its twin rover Opportunity , have now been exploring the red planet for over three years . Both Spirit and Opportunity have found evidence that parts of Mars were once wet .
