A discussion of the possibility of placing a cryogenic computer in outer space to maintain the near-absolute temperature necessary for these potentially large-capacity, fast, random-access super-conductive memory systems. The author surveys the principles, prospects, and problems associated with such systems, and presents a functional design of a space-based cryogenic computer. Major design problems are examined, and it is concluded that the possibility of achieving an economically feasible system in 20 years is fairly strong. 25 pp.
