Dr. Greg Matloff, is a leading expert in possibilities for interstellar propulsion , especially near-Sun solar-sail trajectories that might ultimately enable interstellar travel. and is an astronomy professor with the physics department of New York City College of Technology, CUNY, a consultant with NASA Marshall Space Flight Center, a Hayden Associate of the American Museum of Natural History and a Corresponding Member of the International Academy of Astronautics. He co-authored with Les Johnson of NASA and C Bangs Paradise Regained (2009), Living Off the Land in Space (2007) and has authored Deep-Space Probes (edition 1: 2000 and edition 2: 2005). With C Bangs, he authored "Biosphere Extension: Solar System Resources for the Earth," in 2011. As well as authoring More Telescope Power (2002), Telescope Power (1993), The Urban Astronomer (1991), he co-authored with Eugene Mallove The Starflight Handbook. (1989). His papers on interstellar travel, the search for extraterrestrial artifacts, and methods of protecting Earth from asteroid impacts have been published in JBIS, Acta Astronautica, Spaceflight, Space Technology, Journal of Astronautical Sciences, and Mercury.
