Junk Raft (starts 6:20) Marcus Eriksen discusses what can and cannot be done about the “plastic smog” of microscopic debris permeating the world’s ocean, from the state-sized floating islands of plastic in the Pacific, to the microscopic debris that sinks all the way down the the deepest parts of the Pacific, OR gets eaten and into the food chain. Eriksen is author of the book Junk Raft, recounting his adventures when he sailed the Pacific from L.A. to Hawaii on a raft made of garbage to bring attention to the issue.

Because Pluto is so far away, it took nearly 10 years of travel for the spacecraft to reach that distant dwarf planet — and that was after a decade of work to get the spacecraft to the launch pad. Planetary scientists Alan Stern and David Grinspoon have written a new book, called: “Chasing New Horizons: Inside the Epic First Mission to Pluto”. The book tells the story of developing and operating the New Horizon mission.
