Greeley began teaching at ASU in 1977 with a joint professorship in the department of geology and the Center for Meteorite Studies. He studied wind processes on Earth and other planets and conducted photogeological mapping of planets and satellites among other research projects. In 1986, Greeley left the Center for Meteorite Studies to serve as chair of the department of geology.
Greeley, a pioneer in the planetary geology field, served as the director of the NASA-ASU Regional Planetary Image Facility and principal investigator of the Planetary Aeolian Laboratory at NASA-Ames Research Center. He served on and chaired many NASA and National Academy of Science panels and he was involved in nearly every major space probe mission flown in the solar system since the Apollo Moon landing. Mission projects included the Galileo mission to Jupiter, Magellan mission to Venus and Shuttle Imaging Radar orbiter around Earth. He was also part of the data analysis program for the Voyager 2 mission to Uranus and Neptune. His projects focused on the moons of these distant bodies. Passionate about Mars exploration, he has been involved with several missions to the Red Planet, including Mariner (6, 7, 9), Viking, Mars Pathfinder, Mars Global Surveyor and the Mars Exploration Rovers. He is a co-investigator for the camera system onboard the European Mars Express mission.
