OSIRIS-REx Mission Quiz: Test Your Knowledge

The Canadian Space Agency (CSA) is collaborating with NASA on the OSIRIS-REx sample-return mission that launched on September 8, 2016. The mission will help answer fundamental questions about how our solar system formed, how life began and how we can avoid asteroid impacts with Earth. OSIRIS-REx also marks the first time the CSA is part of an international sample-return mission.
