Cashing in on the space race and impending Apollo moon landings, Mattel brought out the first Major Matt Mason figure in 1966. In 1970, a boy can get fellow astronauts Sgt. Storm, Lt. Jeff Long and Doug Davis (a civilian). There are also as a Lunar Crawler vehicle, 3-level Moon Base and several aliens...including Callisto, who hails from Jupiter.
