Asteroid Bennu’s Visitor From Earth

Spacecraft OSIRIS REx is now orbiting a 260-meter asteroid named Bennu.  Principal investigator Dante Lauretta returns to tell us what has already been learned, and to preview the excitement that is still to come, including the probe’s descent to the surface for collection of a pristine sample. Want one of five  Blu-ray copies of First Man, the movie about Neil Armstrong? Consider entering this week’s What’s Up space trivia contest that also offers Dante Lauretta’s two great board games about space exploration and astronomy.
