Rover over

The Opportunity robot rover on Mars is set to begin a treacherous journey into a deep meteor crater:

"Opportunity already has been exploring layered rocks in cliffs around Victoria Crater. The team has planned the descent carefully to enable an eventual exit, but Opportunity could become trapped inside the crater or lose some capabilities. The rover has operated more than 12 times longer than its originally intended 90 days."

I’m sure most people have forgotten the rover is still out there. This could help them remember.
