The Juno spacecraft will enter orbit at Jupiter on July 4th. It carries a camera that will send back spectacular images from just above the swirling clouds of that mighty planet. Planetary scientist Candy Hansen will tell us how we can help decide what it will view. You can watch Emily Lakdawalla deliver illustrated presentations to two very different audiences. Bruce Betts becomes the masked astronomer on this week’s What’s Up.
