Beginning on 14 November 2016, the U.S. worldwide educational cable network National Geographic Channel debuted its "global" overhaul and rebranding of the channel with its entirely new primetime lineup that night: the much anticipated, multi-million-dollar docudrama miniseries "Mars", followed by the reboot of "Explorer", and then "Star Talk", a lighthearted panel discussion series loosely centered around astrophysics and astronomy, hosted by astrophysicist Dr. Neil DeGrasse Tyson. Bacon became the presenter for the "Explorer" programme, which comprises several (usually three) short films, introduced by Bacon and shot from all over the world, involving matters of social, political, environmental, and/or humanitarian significance. Each film is then discussed before a live studio audience with Bacon moderating and usually includes the filmmaker or another representative of the film. Then, at least one expert on either side of the issue also joins the discussion. The live-audience segments of each episode of "Explorer" are filmed at CBS Studios in New York City. For the debut show, Bacon hiked through Yosemite National Park with President Barack Obama.
