Science: Spacecraft: Probe, or Science: Space: Planets

My new idea [first link] kinda fits in Science: Space: Satellite, because it *can* be used in Earth orbit, but that's more suited to Earth-only orbiters than to other-body orbiters, and it's not at all suited to flyby probes, entry/descent probes, landers, penetrators, impactors, aircraft, boats, submarines, etc. for other bodies. I have a bunch of those. The only kind with its own category now is rovers, and I don't have as many ideas for those.

I have two proposals, either of which I think would solve this problem.

My first proposal is to create Science: Spacecraft: Probe. Science: Space: Rover can be moved to Science: Spacecraft: Probe: Rover, and additional subcategories of Science: Spacecraft: Probe can be made as enough ideas are posted. Below are linked some candidate ideas to be moved to the new category Science: Spacecraft: Probe. It would certainly not be the least populated category.

My second proposal is to create Science: Space: Planets (and eventually for other types of bodies like stars and galaxies). Then missions to the planets would have a category just like asteroid missions and moon missions already do. All planetary missions would go in there. All asteroid and moon missions, even if the probes are of the same types as for the planetary missions, would go in Science: Space: Asteroid and Science: Space: Moon as they already do. But that might lead to confusion as to which category the Mercury colonization ideas (of which we have at least two!) should go in, Science: Space: Planet or Science: Space: Colony.
