Flickr group "In the Year 2000" participant "adm" scanned a few pages from a 1961 Life magazine, including these dreamt-up images of a solar wind-power regatta. adm says:
this is from the april 21, 1961 issue of Life magazine. most of the issue is devoted to yuri gagarin, who had just returned to earth, and americans (judging from the tone of the articles) were FREAKING OUT that the soviets had beaten them to space. much of the issue reads like a study of a national identity crisis. so, life tried to pick up everyone's spirits by running a few drawings of what OUR spaceships would look like, if we ever got around to building any.
