For 15 years Opportunity has provided us with a window to another planet. When - not if, but when - we get there, I hope someone finds it, dusts it off and puts it in a place of honor. There's a Navy saying "Fair winds and following seas..." ... Not sure what the Martian equivalent should be, but I feel like there should be something.
