"Skylab included the Apollo Telescope Mount (a multi-spectral solar observatory) , Multiple Docking Adapter (with two docking ports) , Airlock Module with extravehicular activity (EVA) hatches, and the Orbital Workshop (the main habitable space inside Skylab). Electrical power came from solar arrays, as well as fuel cells in the docked Apollo CSM. The rear of the station included a large waste tank, propellant tanks for maneuvering jets, and a heat radiator. Numerous experiments were conducted aboard Skylab during its operational life. Solar science was significantly advanced by the telescope, and observation of the Sun was unprecedented. Thousands of photographs of Earth were taken, and the Earth Resources Experiment Package (EREP) viewed Earth with sensors that recorded data in the visible, infrared, and microwave spectral regions. The record for human time spent in orbit was extended beyond the 23 days set by the Soyuz 11 crew aboard Salyut 1, to 84 days by the Skylab 4 crew. " (from Wikipedia). Very Good- .
