Greg Matloff


Consciousness and the Cosmos Through the Scientist's Vision

Greg Matloff is a leading expert in possibilities for interstellar propulsion, especially near-Sun solar sail trajectories that mightstellar travel. He is also a professor with the PhysicsDepartment 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 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). As well as authoring More Telescope Power (2002), Telescope
(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 Journal of the British Interplanetary Society, Acta Astronautica, Spaceflight, Space Technology, Journal of Astronautical Sciences, and Mercury. His popular articles have appeared in many publications, including Analog and IEEE Spectrum. In 1998, he won a $5000 prize in the international essay contest on ETI sponsored by the National Institute for Discovery Science. He served on a November 2007 panel organized by Seed magazine to brief Congressional staff on the possibilities of a sustainable, meaningful space program. 

    Greg Matloff is a Fellow of the British Interplanetary Society, has chaired many technical sessions, and is listed in numerous volumes of Who’s Who. In 2008 he was honored as Scholar on Campus at New York City College of Technology. His most recent book, co-authored with Italian researcher Giovanni Vulpetti and Les Johnson, is Solar Sails: A Novel Approach to Interplanetary Travel, Springer (2008, 2015). In addition to his interstellar travel research, he has contributed to SETI (the Search for Extraterrestrial Intelligence), modeling studies of human effects on Earth’s atmosphere, inter- planetary exploration concept analysis, alternative energy, in-space navigation, and the search for extrasolar planets.

Synopsis of Major Research Accomplishments and Collaborations, 


1965-1975—Contributed to photometry and radiometry in calibration of

 automatic celestial navigation devices for aircraft and spacecraft.

 Utilized these tools to predict photometric color indices of (then)

 hypothetical extrasolar planets. Began investigations of 

 thermonuclear propulsion for interstellar travel. 

     Collaborators: H. H. Chiu (NYU) and A. J. Fennelly (Yeshiva U.)  


1976-1985—Continued space propulsion studies with concentration on

             thermonuclear ramjets. Applied atmospheric radiative transfer to

             develop new models to analyze stratospheric and tropospheric air 

 pollution effects. Pioneered use of near-Sun passes to calculate

 theoretical performance of space-manufactured solar sails as

 interstellar spacecraft. Analyzed performance of a patented wind

 turbine for urban application.

   Collaborators: M. Hoffert (NYU), R. W. Stewart (NASA), E. Mallove (MIT)


1986-1995—Developed and refined mathematical formalism to estimate

    opticalperformance of space-manufactured, 10-30 nanometer

            metallic monolayer and perforated solar sails. Began investigating

            near-term mission possibilities for Earth-launched extrasolar solar

            sails. Contributed to SETI studies by considering spectral signatures

            of sail-craft departing other stars.

    Collaborators: C. L. Maccone (Alenia), B. N. Cassenti (United Tech. Res.),

            E. Belbruno (Princeton)


1996-2011—Developed for NASA many mission scenarios for interplanetary

    and interstellar solar sails. Contributed to studies of tethers and

            aerocapture techniques. Evaluated possibilities of holographic films on

            solar sails by collaborating on NASA-funded preparation of a prototype

    holographic interstellar message plaque as an art piece. Considered

            new sail configurations including solar-photon thrusters and hollow-body

            sails. Theoretically examined interactions of the near-Sun space

            environment with accelerating interstellar solar sails.
