Planetary Radio: Space Exploration, Astronomy and Science

Lucy in the Sky With Asteroids

A rare alignment of planets and other objects will enable the solar-powered Lucy spacecraft to examine seven asteroids, six of which are among the thousands of Trojan asteroids that orbit ahead of and behind Jupiter. The mission team, include Hal Levison, Cathy Olkin and Mike Sekerak, hope to unlock secrets of our solar system’s origin through these ancient artifacts. Planetary Society correspondent Andrew Jones helps us celebrate China’s Space Day with an update on the Chang’e 4 lunar mission. The space trivia contest returns as just one cog in the universe-spanning machine called What’s Up.
