About LEGO Space

The LEGO Space theme is one of the earliest and expansive themes that began in 1978 and features sets around features astronauts, spaceships, and extraterrestrial life. The first Space themes included an emphasis on space exploration with ships and basic wheeled vehicles and later consisted of more science fiction based sets which consisted of robots, small and large spaceships, and bases. The theme expanded over the years into various subthemes that included space factions and more story lines such as Futuron, Blacktron, Space Police, M:Tron, Spyrius, Unitron, Exploriens, Life on Mars, Alien Conquest and many more.
1991 LEGO Sets
1991 brought LEGO Paradisa, a pastel-toned, beachfront subtheme within Town designed to broaden LEGO’s appeal. Pirates added the Imperial Guards, while Space introduced Blacktron II with modular white-and-black spacecraft. The 9V Train system replaced earlier electric formats, simplifying operation with metal track rails. Technic advanced with motorized models like the Control Center, highlighting LEGO’s growing focus on realistic engineering and interactivity.
