Where we came from, where we are and where we'll be: Spirit's traverse Map on Sol 82

Caption NASA originale:"This map shows the MER Spirit's past and future routes across the Gusaev Crater floor. The solid red line shows where the Rover has traveled so far, from Lander to the rim of the Bonneville crater. The dotted red line indicates proposed future paths to the Columbia Hills.
Rover Team Members have not yet decided which direction Spirit will travel across Bonneville's ejecta (ejecta---->the blanket of material expelled from it during formation) and toward the Hills, as illustrated by the two diverging dotted lines.
Along the way, Spirit will stop to investigate interesting targets, including craters and plain deposits and this journey to the Hills is estimated to last about two months. The underlying image in this map was taken by the camera on NASA's MGS Orbiter".
