Back in 2004, shortly after touchdown, the Mars rover headed into the Cope Rift for some surface feature studies. The following coded message was received from the Mars rover. No communication has been received since. We believe that the message sent contains the final coordinates of the mars rover's black box. It was designed to eject the black box in case of a critical problem. Nobody has been able to break the code. During your flight to Mars, we hope that you will have enough free time to break the code. Assuming that you do, your mission is to recover the black box.
Here is the message as received:

I'm sure I don't have to tell you this, but the terrain in the Cope Rift can tricky so go slow and watch your step.
