Orbits

Open space, where you need a space platform to build because empty space doesn't allow placement for a lot of structures. Space elevators also use orbit, so you can move from the planet to its orbit and back. Some structures you can place only on Land, some only on space platforms, some you can place everywhere. Below is a list of structures and their restrictions:

- Space transport belt/underground belt/splitter (only space platform)
- Deep transport belt/underground belt/splitter  (only space platform)
- Everything in Space production category    (only space platform)
- Space pipe/ground pipe                         (only space platform)
- Long junction space pipe                       (only space platform)
- Space science laboratory                       (only space platform)
- Space platform scaffold/plating                (space platforms)
- Space rails                                    (everywhere)
