Carol (Cari) Sagan Greene
October 19, 2013I am delighted that this tribute is being made to honor Bruce Murray. Along with my brother and Lou Friedman, he helped to found The Planetary Society, the largest grassroots space interest group in the world. I would like his family to know that I am thinking of them at this difficult time...
In 2016, The Planetary Society’s LightSail program will take the technology a step further.
