Also, the mystery of Mars continues to fascinate Michio Kaku, a theoretical physicist, futurist and author. Kaku joins us to talk about how soon humans might visit the red planet, and other advancements from the world of science.

That and more, in hour one of Here & Now’s June 27, 2018 full broadcast.
