"We went to the Moon, and we discovered Earth."
So true. Listen to Neil deGrasse Tyson talking about the simple fact that "you can't put a price on space exploration." It will really give you chills.
Listen carefully as he talks about the defining effects that watching Earth from the Moon
had on humans. Especially if you weren't around when it happened.
Objectively—and anthropologists and sociologists studied this in the wake of the Apollo program—the mere image of the entire Earth from space changed our perception forever. Space exploration created a global sense, humanity united as one species. All of the sudden we knew we were here, alone in the cold. That picture of Earth rising over the Moon's horizon
prompted humans to realize that this place is where we will have our last stand. It prompted humans to think
about who we are. And as Tyson says, you can't put a price on that.
