The projector could be controlled by a console where an individual presenter would provide specific talks or lectures. By the mid-1970s, automation features were added, which led to the creation of prerecorded shows. Most visitors to the facility would have seen an automated 40- to 45-minute audio/visual show on a particular space-related topic. Two types of shows were typically alternated on a daily basis: one aimed at families with young children and another aimed at older children and adults. Typical shows aimed at both audience types were built around themes such as space travel, the mythical stories behind the constellations, and around Christmas-time, a show that investigated theories on stellar explanations for the Star of Bethlehem. A listing from 1970 includes shows titled "The Story of Eclipses", which looked at how solar eclipses occur and their scientific importance, "Man and the Zodiac" which explored the history of mythology and astrology with regard to the night sky, and "The Planet Venus" which surveyed the history of the planet in mythology, the planet's motion across the sky and featured imagined views from its surface.
