I’d love to see us plant some kind of telemetering package on one of these that comes close, sort of like hanging a radio on a wild animal just to see where it goes, taking some kind of readings all the way. Don’t know what kind of readings, surely there are smart people that could figure that out. I just want to be able to click on the web cam beaming back from the outer reaches of the solar system, and listen to the electronic noise set to music.
Isaac Asimov suggested planting a satellite on a comet for outer solar system exploration, suggesting that it would be quicker than building whatever kind of fast propulsion system we could manage. Of course, it’s pretty unlikely that we could build something that could hang on tight enough — unless it was one of these asteroids / dark comets. :’)
