What makes a hobby? Can we really just do something for its own sake anymore? Interesting stuff from @newyorker.com:

Over the last few years, I had the pleasure of serving on the Mars Sample Return Measurement Definition Team. Our driving question was straightforward enough: what do we do with precious samples that will hopefully be returned from Mars in the coming years?
