Spirit's Path to Bonneville
Scientists created this overlay map by laying navigation and 
panoramic camera images taken from the surface of Mars on top of one 
of Spirit's descent images taken as the spacecraft descended to the 
martian surface.  The map was created to help scientists track the 
path that Spirit has traveled to date and to put into perspective the 
distance left to travel before reaching the edge of the large crater 
called "Bonneville."

The area boxed in yellow contains the ground images that have been 
matched-to and layered on top of the descent image.  The yellow line 
shows the path that Spirit has traveled and the red dashed line shows 
the intended path for future sols.  The blue circles highlight 
hollowed areas on the surface - like Sleepy Hollow, and the just 
reached Laguna Hollow.  Scientists use these hollowed areas - which 
can be seen in both the ground images and the descent image - to 
correctly match up the overlay.

Field geologists on Earth create maps just like this to assist them 
in tracking their observations.
