The Mars Rover

Nasa have made small machines to go to Mars.
These are called Mars Rovers and have done 2 missions.
The first one cost 300 million dollars.
The second cost 200million dollars.

The Rovers were called Spirit and Opportunity.
A girl named them in a "name the Rovers" competition at school!
The Rovers helped us see a lot of features from Mars like The Whitewater Lake rock
