In 1991 in Toulouse, France, the International Space University studied an international human Mars mission. They proposed a crew of 8 traveling to Mars in a nuclear-powered vessel with artificial gravity provided by rotation. On the surface, 40 tonne habitats
Komarr (fictional planet) Komarr (fictional planet) Komarr is a fictional planet in Lois McMaster Bujold's "Vorkosigan Saga" series of novels and stories.
