Made prior to the launch of Skylab, the pioneering research laboratory in space, this film covers the module's facilities for experimentation in the fields of biomedical science, solar physics, crew operations, astrophysics and space technology. The film describes 6 of the 90 or so experiments performed on Skylab, using demonstrations performed in a simulator of the module. Five ultraviolet and visual photography experiments are described, with images of hot young stars, solar flares, the Earth's atmosphere and Earth's terrain. After describing the use of scientific airlocks, the following experiments are demonstrated: UV astronomy experiment, UV solar photography experiment, particle collection experiment [micrometeorite collection device], UV airglow horizon photography, Earth resources/terrain photography, coronograph contamination measurement. Equipment is shown in detail for each experiment.
