Why haven’t we gone back to the Moon? What are the responsibilities of the Space Force? Is Mars the new end goal for exploration? Neil deGrasse Tyson and comic co-host Ray Ellin answer fan-submitted questions on the “new” Space Race.
The Science Guy takes the mic to answer your questions for him about evolution, technology, the human exploration of space, and even Leonard Nimoy, chosen from Twitter, Facebook and Google Plus by co-host Chuck Nice.
