Inflatable Station Concept
Unlike many other early space station concepts, this design actually made it out of the concept phase and into production, though no models were ever flown. This particular station was 30-feet and expandable. It was designed to be taken to outer space in a small package and then inflate in orbit. The station could, in theory, have been big enough for 1 to 2 people to use for a long period of time. A similar 24 foot station was built by the Goodyear Aircraft Corporation for NASA test use. The concept of space inflatables was revived in the 1990s.
Orbit and Launch Facility Concept
This is a concept drawing of an orbit and launch facility. It was to use a nuclear SNAP-II nuclear power supply on the end of the long telescoping boom. Nuclear reactors were considered dangerous, which is why in this concept drawing it was located so far away from the habitat part of the station. Creators envisioned the structure being built in orbit to allow assembly of the station in orbit which could be then larger than anything that could be launched from Earth. The two main modules were to be 33 feet in diameter and 40 feet in length. When combined the modules would create a four deck facility, 2 decks to be used for laboratory space and 2 decks for operations and living quarters. The facility also allowed for servicing and launch of a space vehicle. Though the station was designed to operate in micro- gravity, it would also have an artificial gravity capability.
Solar Power Satellite
This is what an artist envisioned the Solar Power Satellite would look like. Shown is the assembly of a microwave transmission antenna. The solar power satellite was to be located in a geosynchronous orbit, 36,000 miles above the Earth's surface.
Power Tower Space Station Concept
This is an artist's conception of the proposed "Power Tower" space station configuration, shown with the Japanese Experiment Module attached. This model and several others were examined before deciding on the Space Station Freedom structure that was later abandoned in favor of the International Space Station.
