:Geoffrey A. Landis

Landis was born in Detroit, Michigan, and lived in Virginia, Maryland, Philadelphia, and Illinois during his childhood. His senior education was at New Trier High School, Winnetka, Illinois. He holds undergraduate degrees in physics and electrical engineering from the Massachusetts Institute of Technology (MIT). He also holds masters degrees in physics and engineering and a PhD in solid-state physics from Brown University. He is married to science fiction writer Mary A. Turzillo and lives in Berea, Ohio.

After receiving his doctorate at Brown University, Landis worked at the NASA Lewis Research Center (now NASA Glenn) and the Ohio Aerospace Institute before accepting a permanent position at the NASA John Glenn Research Center, where he does research on Mars missions, solar energy,{{cite journal|first=Geoffrey A.|last=Landis|title=Reinventing the Solar Power Satellite|journal=NASA Tm-2004-212743|pages=737|publisher=NASA, Glenn Research Center|date=February 2004|url=http://gltrs.grc.nasa.gov/reports/2004/TM-2004-212743.pdf|url-status=dead|archive-url=https://web.archive.org/web/20071031063220/http://gltrs.grc.nasa.gov/reports/2004/TM-2004-212743.pdf|archive-date=October 31, 2007|bibcode=2002iaf..confE.737L}} and technology development for future space missions.{{cite web |url= http://ecolloq.gsfc.nasa.gov/archive/2007-Fall/announce.landis.html

Landis was a fellow of the NASA Institute for Advanced Concepts ("NIAC"), where he worked on a project investigating the use of laser- and particle-beam pushed sails for propulsion for interstellar flight.{{cite web |url= http://www.niac.usra.edu/studies/4Landis.html |title=NASA Institute for Advanced Concepts Phase I studies |work=NASA Institute for Advanced Concepts |location=Atlanta, Georgia |access-date=December 27, 2010}} In 2002 Landis addressed the annual convention of the American Association for the Advancement of Science on the possibilities and challenges of interstellar travel in what was described as the "first serious discussion of how mankind will one day set sail to the nearest star". Dr. Landis said, "This is the first meeting to really consider interstellar travel by humans. It is historic. We're going to the stars. There really isn't a choice in the long term." He went on to describe a star ship with a diamond sail, a few nanometres thick, powered by solar energy, which could achieve "10 per cent of the speed of light".{{cite news |url=https://www.telegraph.co.uk/news/worldnews/northamerica/usa/1385077/Reach-for-the-stars-on-a-beam-of-light.html |title=Reach for the stars on a beam of light |work=Daily Telegraph |location=London |publisher=Telegraph Media Group|last=Highfield|first=Roger|date=February 16, 2002 |access-date=March 25, 2010}}
