- A fantastic idea Carl Sagan showed Johnny Carson in 1976 is about to become reality: A solar sail, one that could theoretically allow a spacecraft to travel using nothing more than the physical force of sunbeams. 40 yrs later, The Planetary Society -a group he founded- is making his dream a reality. http://www.washingtonpost.com/news/speaking-of-science/wp/2015/05/06/a-fantastic-idea-carl-sagan-showed-johnny-carson-in-1976-is-about-to-become-reality/?tid=rssfeed 15 comments space
- Solar Sails were proposed 400 years ago, by Johannes Kepler. He wrote to Galileo “Provide ships or sails adapted to the heavenly breezes, and there will be some who will brave even that void.” In 1980 Carl Sagan co-founded the Planetary Society, and now their LightSail 2 flies entirely on sunlight. https://www.supercluster.com/editorial/solar-sails 4 comments space
