There should be ISs and space. There should be a satellite launch pad that launches different prebuilt sattellites. but to make it more minecrafty u have to go up in a space ship to the satellite and u have to bring special blocks to build room and stuff on it and a space ship yard where u have to designate as space ship docking or something like that. and u should be able to fly around in space and when u get close enough it prompts u askin if u wanna go to that planet/spacey object. U should have to install modules like, oxygen distributor, greenroom with oxygen collectors, space docks, storage, and other stuff like that. it should all be designated somehow but customized at will. should be sci-fi but also customizable so it is minecrafty. also the asteroid planet should be a giant world fille with big asteroids made of some meteor rock and have titanium and some other ores. also u should when u jump out one side of bottom or top of the world area. u appear in space in ur rocket because it swings around and pulls u into it.
