The Stand-Alone Laboratory is a station part which has everything necessary to serve as a one piece functional space station.
It comes equipped with built-in Solar Panels to re-charge its on board batteries (stored as cargo), a rocket engine with internal fuel tanks (which can be re-filled). It also comes equipped with eight Cargo slots pre-loaded with 2 Batteries, 2 Oxygen Tanks, 2 Carbon Dioxide Scrubbers, and 2 Water Tanks. Its solar panels generate 100 units of electricity (without the batteries on-board), of which it consumes 6. It is essentially NASA's space station Skylab, made out of a Saturn V Third Stage.
- You can build the Skylab (albeit two radiators instead of one) by adding a hub and two MSS Sensor Modules.
- On top of the "X" of the solar panels is the Apollo Telescope Mount (keep in mind that Hubble was not yet launched).
- There are some pieces of glass inside the laboratory, it maybe either the experiments being conducted or the mirrors and lenses of the telescope, as its real-life counterpart has one.
- If you drag the part from the menu in the rocket building section, and discard it, you can see for a split-second something like a retracted Solar Panel Large without the cover.
