Canada's role in the OSIRIS-REx Mission

These new findings highlight the importance of asteroid sample return missions like OSIRIS-REx. A Canadian lidar instrument was used to help select the Bennu sample site. In exchange for this contribution, Canada will receive 4% of the sample, making it the fifth country to preserve and study a sample collected from space. It's also thanks to this contribution that Canadian researchers are part of the international science team.
