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 [[Solar sail|sails]] for propulsion for [[interstellar propulsion|interstellar flight]].<ref name="niac">{{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}}</ref> 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".<ref>{{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}}</ref>
