A blimp is probably preferred for Venus anyway.

A Jupiter chopper would be insane.

37 dot 5! we need to take the time.

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!

Maybe some design could also work on Neptune's moon, Triton?

That's 50% of those places that we also know how to land on, soon to be 75%.

How is this not a Thanoscopter joke?
