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.
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.
Much of Landis' technical work has been in the field of developing solar cells and arrays, both for terrestrial use and for spacecraft.
Landis has worked on a number of projects related to developing technology of human and robotic exploration of Mars and scientific analysis of the Martian surface, including studies of the performance of photovoltaic cells in the Mars environment, the effect of Martian dust on performance, and technologies for dust removal from the arrays.
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, where his work includes observations of Martian dust devils, atmospheric science measurements, and observation of frost on the equator of Mars. He was also a member of the Mars ISPP Propellant Precursor experiment team for the Mars Surveyor 2001 Lander mission, an experiment package to demonstrate manufacture of oxygen from the Martian atmosphere (which was cancelled after the failure of the Mars Polar Lander).

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".
In 2017, Landis's work was the subject of the bookLand-Sailing Venus Rover With NASA Inventor Geoffrey Landis, published by World Book as part of their "Out of This World" book series for ages 10–14+.
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.
Landis has also published a number of poems, much of it involving science fiction or science themes. He won the Rhysling Award twice, for his poems "Christmas, after we all get time machines" in 2000 (which also won the 2000 Asimov's Reader's Award for best poem), and for "Search" in 2009, and the Dwarf Stars Award in 2010, for the poem "Fireflies". He has won the Asimov's Reader's award for best poem three times, most recently in 2014, for his poem "Rivers". In 2009, he won 2nd place in the Hessler Street Fair poetry contest for his poem "Five Pounds of Sunlight," and 1st place in 2010 for "Human Potential."
His poetry collection Iron Angels was published in 2009.
Landis has also written non-fiction and popular science articles, encyclopedia articles and columns for a large range of publications, including Analog Science Fiction and Fact, Space Sciences, Asimov's Science Fiction, Spaceflight, and Science Fiction Age. His article "The Demon Under Hawaii" won the Analog Analytical Laboratory Award for best science article in 1993.

The Deep Impact mission is also significant because it illustrates the extent of science fiction's influence on space technology. "Science fiction is inspiring," confirms Geoffrey Landis, a NASA scientist who is also an award-winning science-fiction author. "Science fiction shows us things that are beyond the realm of the possible-today, that is."
