THE INSPIRATION: CARL SAGAN
Carl Sagan was Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. He was heavily involved in the American space program, from briefing Apollo astronauts before their Moon flights, to leading experiments on the Mariner, Viking, Voyager, and Galileo expeditions, and investigating mysteries like Titan's red haze.
He was a strong advocate of the sciences and a great supporter of the Sciencenter, as well as prominent memeber of the Ithaca community for more than 30 years. We name the planet walk in Carl Sagan's honor in the hopes of continuing his mission to excite future generations about the romance of the scientic enterprise and to convey something of the preciousness and fragility of our tiny world in the context of the vastness of the Cosmos.
