The paper “A Survey of Space Settlement Designs” by Thomas Marotta has been just been published in the NSS Space Settlement Journal.

Abstract

The author compiled every known orbital space settlement design into a database. Grouped into chronological ‘eras,’ the database describes basic information for each design: population capacity, dimensions, gravity level, energy source, etc. Using this information one can conclude that interest in space settlement is increasing, 1g is the preferred gravity level, solar power is the preferred energy source, and a torus is the preferred geometry. As for location, Earth-Moon Lagrange points dominate but there is a budding movement to place settlements in low Earth orbits. The database is accessible at space.nss.org/media/Space-Settlement-Designs-Database-12-19-16.pdf.
