While originally initiated for mission planning and science, this technology has demonstrated great benefits for Science, Technology, Engineering, and Mathematics (STEM) engagement and inspiration. As a component of NASA’s Science Activation Infrastructure, Solar System Treks are available as resources for NASA Science Activation partners and the greater outreach and education community. As new missions are being planned to a variety of planetary bodies (including the first human missions to Mars), these tools are facilitating the public’s understanding of the missions and engaging the public in the process of identifying and selecting where these missions will land. Initial Trek portals were developed for the Moon; the planets Mercury, Venus, and Mars; the dwarf planet Ceres; the asteroids Vesta, Bennu, and Ryugu; Jupiter’s moon Europa; and eight of Saturn’s moons. New portals for additional bodies are being developed. The project is managed by NASA’s Solar System Exploration Research Virtual Institute and developed at NASA’s Jet Propulsion Laboratory.
