NASA hopes InSight will illuminate Mars' unknown core

Season 2018 Episode 450 | 5m 38s

NASA has successfully landed its spacecraft InSight on Mars, after a long and challenging voyage. Scientists hope InSight will uncover details of what’s under the surface of Mars, including whether the planet’s core is liquid or solid. Science correspondent Miles O’Brien explains to Judy Woodruff why “there’s nothing easy about this” venture and how it might affect future space exploration.
