Witness awe-inspiring footage of the moon and the Earth as captured from the Kaguya lunar orbiter in this National Geographic documentary exploring the past, present, and future of lunar expeditions. It's been 40 years since Apollo astronauts Neil Armstrong and Buzz Aldrin made history by becoming the first men to walk on the moon, and since that time technology has advanced exponentially. Here, Aldrin and NASA scientists discuss the challenges of establishing a lunar outpost and the innovations that could make that possible while reflecting back on the history of the American space program. ~ Jason Buchanan, All Movie Guide.
