オニールのシリンダー 島3号
A [[space habitat]] design by "Gerard K. O'Neill":[https://en.wikipedia.org/wiki/Gerard_K._O%27Neill].
He called that particular design "Island Three" in his 1976 book "The High Frontier: Human Colonies in Space":[https://en.wikipedia.org/wiki/The_High_Frontier:_Human_Colonies_in_Space].

This cylinder-type design is known for appearing (and [[colony_drop|being dropped]]) in most of the [[Gundam]] series ("with a few exceptions":[http://gundam.wikia.com/wiki/Space_Colony#Additional_Colonies]).
