Add caves

I feel that it would be really cool to have some type of career contract where u gotta goto Luna on a pinned location and have a rover go into a small cave or smth,
At least make it so you can make caves in planet studio.
I just feel that cave exploration on different planets would add a lot of, well I don’t know the word but it would make the game a lot better

And plus, I made those two mining trucks and they have no caves to go in.
But seriously, imaigine going to Vulco and there is a big cave that leads to the planet’s core and it’s a career contract to go there. I mean like tell me that wouldn’t be awsome.
