A rover was recently sent up to mars to check if there was ever life on mars. It's looking for signs of life, love and the pursuit of happiness...oh wait wrong quote. But it is looking for signs of life or even signs of things to support life such as water. Curiosity is the name of the rover and it's on mars collecting rock samples and taking pictures just to see if mars is or ever was capable of supporting life.
A lovely picture showing the good side of Curiosity
