interstellar ark : ウィキペディア英語版 | interstellar ark
An interstellar ark or spaceark is a conceptual space vehicle that some have speculated could be used for interstellar travel. Interstellar arks may be the most economically feasible method of traveling such distances. The ark has also been proposed as a potential habitat to preserve civilization and knowledge in the event of a global catastrophe. ==Size considerations for generation ship proposals==
Such a ship would have to be large, and the only adequate technology likely to be available (even assuming the most favorable economic and political factors) soon enough to make plans is the Project Orion concept of propulsion by nuclear pulses. The largest spacecraft design analyzed in Project Orion had a 400 m diameter and weighed approximately 8 million tons. It could be large enough to host a city of 100,000 or more people.
