The total cost of Curiosity to date is well under 5% of the cost of the recent trip humans took around the moon (something like $3B vs. $90B, or $20 vs. $600 per US taxpayer). Imagine the amount of science that could get done if we gave even half the budget of crewed spaceflight to rover / probe style exploration.

Curiosity is a teenager now? Damn, I didn't need to feel this much older today..

I am happy to know this emblem of knowledge stream keeps coming until 2035. It is wonderful to know our innovations have flown 200 odd million miles and work for so long!
