I'm excited for Dragonfly, because on the list of places in the solar system that I desperately want more pictures from, 'Titan's surface' is right up there at the top with 'Jupiter's atmosphere.'

Sure. 25% --> 37% ... as long as you (for some arbitrary reason) only consider 8 "places" in the solar system.
7 of those are planets, but Titan is a moon. If we're going to include moons, then there's going to be a whole lot more than 8 "places" in the solar system, so the percentage of places where helicopters can work is going to be greatly reduced. If we get really pedantic and consider any orbiting body in the solar system to be a "place", then there will be hundreds, thousands of them where helicopters can't possibly work, once you start tallying up asteroids and comets.
Also, why does the list include 7 planets, not 8? What? Are you not interested in trying to make a helicopter work on Mercury? That's quitter talk!
