August 1, 1971 - Apollo 15 Lunar Module Pilot James Irwin gives a military salute while standing beside the deployed U.S. flag during the Apollo 15 lunar surface extravehicular activity (EVA) at the Hadley-Apennine landing site. Hadley Delta in the background rises approximately 4,000 meters (about 13,124 feet) above the plain. The base of the mountain is approximately 5 kilometers (about 3 miles) away.

Who owns the moon? No, it's not Google (yet.) According to the United Nations Outer Space Treaty, no nation can claim sovereignty over the Moon ... but only 102 countries have signed this accord to date. And the asteroids? Space-ownership is still a major unresolved issue that deserves attention, and Vsauce tries to address it in this episode. Also: what about killing an alien who just landed in your backyard ... would it even be illegal? Shouldn't we have a couple of laws about that? And is there really space dust falling to Earth right now?
