The Planetary Society's Kate Howells joins to discuss two exciting developments in space exploration. Over the weekend, a probe named "Lucy" blasted off from Cape Canaveral, beginning a decade-long mission that will culminate in the first flyby of a pair of binary asteroids as old as the Solar System. And later this year, NASA will launch the James Webb Space Telescope, which will enable scientists to study how the first galaxies were formed, and learn about potentially habitable planets outside our solar system.
