Return with us to the evening of July 4, 2016 and the exciting arrival at Jupiter of the Juno orbiter. You’ll hear the moment of successful orbital insertion. Several of the mission’s key contributors reveal how Juno accomplished this feat, along with what they hope the spacecraft will tell us about the giant planet. A Juno pin and t-shirt are waiting for the winner of the new What’s Up space trivia contest.

Question from the week before:

What is the ratio of the equatorial surface gravity of the Sun to the force or pull of gravity at the surface of the Earth? (We’ll define the “surface” of the Sun as the edge of the photosphere or visible surface.)
