Are there any plans to make moons, planets and asteroids voxel-based so the terrain can be edited by mining and blowing stuff up?

I know there will be mining. You will be interacting with these within a certain capacity, but I don't think we've elaborated on all of that yet and to what extent that is. So it'd probably be premature if I dug into it.

For viewers at home, you can almost certainly expect a feature on that at some point between now and its eventual release.

Oh, absolutely, 100%. And to that point, hopefully people have seen, or if they're new to this will check out and understand, that anytime we get something that's a little bit bigger and chunkier and it's a few steps into really what it's going to be, we try to show it off and highlight it as quick as we can, in a sense just to show the progress of what we've done.
