The Exploration of the Moon and Asteroids by Secondary Students (ExMASS) program is managed by the Center for Lunar Science and Exploration (CLSE) and funded through the NASA Solar System Exploration Research Virtual Institute (SSERVI). ExMASS is an academic year-long lunar/asteroid research program that envelops students in the process of science. At the end of the year, student teams compete for a chance to present their work at the annual Exploration Science Forum.
