The OSIRIS-REx asteroid mission team is gearing up to send a spacecraft to a minor planet, Bennu, and return a sample for analysis. It‘s one of the most amazing planetary science missions of all time!

The great OSIRIS-REx outreach team, led by Dolores Hill of the University of Arizona, has produced some terrific videos explaining aspects of asteroid science.

I encourage you to check out one of the latest, on prograde and retrograde motions.  Enjoy!
