Target Asteroids! is a citizen science project which engages amateur astronomers in taking images of potential asteroid spacecraft targets. The purpose is to collect data (e.g., astrometry and photometry) on asteroid targets to better characterize them physically and engage amateurs in the mission to encourage interest in STEM education and careers and citizen contributions to research. OSIRIS-REx team members work with amateur astronomers to provide guidance, monitoring and collection of data.
