Juno will enter Jupiter orbit on July 4th. Mat Kaplan talks with the mission’s Principal Investigator, Scott Bolton at the Jet Propulsion Laboratory. Bill Nye helps prepare us for this exciting encounter and the science that will follow. Emily Lakdawalla has the scoop on China’s next lunar mission—a rover on the Moon’s mysterious farside. And a Chinese mission from the past is at the core of this week’s space trivia contest on What’s Up.
This week's question:
