Geoffrey A. Landis

Geoffrey Alan Landis (born May 28, 1955) is an American scientist, working for the National Aeronautics and Space Administration (NASA) on planetary exploration, interstellar propulsion, solar power and photovoltaics. He holds nine patents, primarily in the field of improvements to solar cells and photovoltaic devices and has given presentations and commentary on the possibilities for interstellar travel and construction of bases on the Moon, Mars, and Venus.

Supported by his scientific background Landis also writes hard science fiction. For these writings he has won a Nebula Award, two Hugo Awards, and a Locus Award, as well as two Rhysling Awards for his poetry. He contributes science articles to various academic publications.

Biography
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) 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.

Career
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, and technology development for future space missions. He holds nine patents, and has authored or co-authored more than 300 published scientific papers in the fields of astronautics and photovoltaics. He was a member of the Rover team on the Mars Pathfinder mission, and named the Mars rock, "Yogi". He is a member of the science team on the 2003 Mars Exploration Rovers mission.

Landis has commented on the practicalities of generating oxygen and creating building materials for a future Moon base in New Scientist, and on the possibilities of using readily available metallic iron to manufacture steel on Mars.

He is the recipient of numerous professional honors, including the American Institute of Aeronautics and Astronautics Aerospace Power Systems Award and the NASA Space Flight Awareness award

NASA Institute for Advanced Concepts
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. 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".

He was selected again as a NASA Innovative Advanced Concepts fellow in 2012, with an investigation of a Landsailing rover for Venus exploration, and in 2015 was the science lead on a NIAC study to design a mission to Neptune's moon Triton.

Academic positions
In 2005–2006, he was named the Ronald E. McNair Visiting Professor of Astronautics at MIT, and won the AIAA Abe M. Zarem Educator Award in 2007. Landis has also been a faculty member of the International Space University; in 1998 he was on the faculty of the Department of Mining, Manufacturing, and Robotics in the Space Studies Program, and in 1999 he was on the faculty of the 12th Space Studies Program at the Suranaree University of Technology in Nakhon Ratchasima, Thailand. and co-chair of the student project "Out of the Cradle." He was also a guest lecturer at the ISU 13th Summer Session Program in Valparaíso, Chile.

As a writer, he was an instructor at the Clarion Writers Workshop at Michigan State University in 2001. He was a guest instructor at the Launch Pad workshop for 2012.

History
Landis first science fiction story, Elemental, appeared in Analog in December 1984, and received a nomination for a Hugo award as well as earning him a nomination for the John W. Campbell award for Best New Writer. In the field of science fiction, Landis has published over 70 works of short fiction, and two books. He won the 1989 Nebula Award for best short story for "Ripples in the Dirac Sea" (Asimov's Science Fiction, October 1988), the 1992 Hugo Award for "A Walk in the Sun" (Asimov's Science Fiction, October 1991), and the 2003 Hugo for his short story "Falling Onto Mars" (Analog Science Fiction and Fact, July/Aug 2002).

His first novel, Mars Crossing, was published by Tor Books in 2000, winning a Locus Award. A short story collection, Impact Parameter (and Other Quantum Realities), was published by Golden Gryphon Press in 2001 and named as noteworthy by trade magazine Publishers Weekly. He has also won the Analog Analytical Laboratory Award for the novelette The Man in the Mirror (2009). His 2010 novella The Sultan of the Clouds won the Sturgeon award for best short science fiction story, and was nominated for both the Nebula and Hugo awards.

He attended the Clarion Workshop in 1985, with other emerging SF writers such as Kristine Kathryn Rusch, Martha Soukup, William Shunn, Resa Nelson, Mary Turzillo and Robert J. Howe.
