An accomplished scientist, Carl Sagan was an outspoken and inquisitive astronomer, cosmologist, astrophysicist, astro-biologist, and environmental activist. He earned more than three degrees, was a Harvard lecturer, Cornell University professor and founder of the International Planetary Society, to list only a few of his credentials. He is remembered for his contributions to Mariner 2, the world’s first successful interplanetary spacecraft, NASA’s Viking explorations of Mars, Voyager explorations of the outer planets, and authoring hundreds of scientific papers and popular books on science and astronomy.
Many might remember him as the host of the PBS Cosmos TV series, the author of Contact, or the man who said “We’re made of star stuff.” But for some he is most notably remembered for his gift for translating scientific endeavors into the language of human emotion, and his humanitarianism and philosophical perspectives on the human condition. Sagan constantly reminded us that at the heart of technical and scientific innovation is the notion that we are all connected in our shared journey through the vast and infinite Universe.
