Planetary Clip: How Important Is Space Travel to Humanity?

Space travel changed how humans understand Earth. The documentary Planetary examines that impact.

Anyone born after, say, 1970 probably takes it for granted now, but space travel fundamentally changed how we humans understand Earth and our lives on it. The documentary Planetary examines that impact across the world.

"One of the truly extraordinary events of the 20th century was space travel," philosopher David Loy says in the doc. "And by that I don't simply mean the fact that we went to the Moon and came back, but that this gave us a totally different perspective on the Earth."

That perspective, according to interviews with everyone from astronauts to philosophers in the documentary, has lead us to understand better the interconnectedness of people on Earth—something the film explores in depth.

Planetary will hit select theaters and Vimeo On Demand for Earth Day tomorrow. Check out an exclusive clip from the film above and the trailer below.
