Geoffrey A. Landis
Our Science Guest of Honor

Geoffrey A. Landis is a scientist at the NASA John Glenn Research Center. He was a member of the Mars Pathfinder scientific team, where he analyzed solar energy and dust on Mars, and is now working on advanced concepts for spaceflight. He was one of the first fellows of the NASA Institute of Advanced Concepts, where he worked on analyzing new concepts for laser-pushed lightsails. His research projects include investigating the effect of the Mars environment on power systems, advanced space propulsion concepts, such as tethers and light-sails, laser- and microwave- power beaming investigations of space resources, and semiconductor physics. He has published over two hundred and fifty scientific papers in the fields of photovoltaics and astronautics, and holds four patents on photovoltaic device designs.

Dr. Landis is also a Hugo- and Nebula- award winning science fiction writer. His novel Mars Crossing won the Locus award for best first novel. His most recent book, Impact Parameter (and Other Quantum Realities), which came out last November, collects some of his award-winning short fiction. It was named by Publisher's Weekly as one of the notable books of the year.
