The USGS was involved in multiple ways, very early in the Apollo program, including high-resolution mapping of the landing spots. Starting in 1963, the USGS Astrogeology Research Program also played an important role in training astronauts destined to explore the lunar surface and in supporting the testing of equipment for both manned and unmanned missions. Harrison H. "Jack" Schmitt, USGS geologist and Apollo 17 astronaut, is still the only geologist to visit the moon. Following the mission, the USGS created a number of products and maps to highlight the explorations of the Apollo astronauts.
