NASA Space Colony Art from the 1970s
November 22, 2012
Three space colony summer studies were conducted at NASA Ames in the 1970s. A number of artistic renderings of the concepts were made by Rick Guidice and Don Davis (I don’t know if they were inspired by SF books – Rendezvous with Rama, Ringworld, etc – or if it’s the opposite).

It consists of a torus, or doughnut-shaped ring, that is 1.8 km in diameter (for the proposed 10,000 person habitat described in the 1975 Summer Study) and rotates once per minute to provide between 0.9g and 1.0g of artificial gravity on the inside of the outer ring via centrifugal force.

A Bernal sphere is a type of space habitat intended as a long-term home for permanent residents, first proposed in 1929 by John Desmond Bernal.
Bernal’s original proposal described a hollow spherical shell 16 km (9.9 mi) in diameter, with a target population of 20,000 to 30,000 people. The Bernal sphere would be filled with air. More HERE.
