I've just had a horrible moment of clarity.
There I was following this exciting - well, exciting to geeky space-following nerds, anyway - probe mission to Pluto and the Kuiper belt, in which it will orbit the far corners of our solar system for the first ever time. It will encircle mysterious Pluto and it's moon Charon. and then on to negotiate huge rocks orbiting the Sun from way out in a 'belt' which marks the edge of our solar system (well, sort of anyway). But then I realised with a horrible dawning that I will be 37 when it 'arrives' there....Christ, what a thought...I feel like I was only about 23 yesterday. Well, obviously I wasn't, and objectively I'm talking crap, but you know what I mean, etc. Reading about space exploration always has a way of making you feel really old...
Edit: apparently, Pluto and Charon and in fact a double planet set rather than one planet and it's moon...
