シド・ミード
The Enzmann starship was detailed in the October 1973 issue of "Analog", with a cover by space artist Rick Sternbach. The spacecraft described in that issue had some differences compared to the 1960s proposal, such as using a 12,000,000 ton (11,000,000 tonnes) ball of frozen deuterium. Enzmanns have been depicted by many space artists including Don Dixon, David A. Hardy, Syd Mead, Bob Eggleton, and Rick Sternbach.
