It's the anniversary of Apollo 11's launch! On July 16th, 1969, we launched the first mission to land humans on the moon. And that's such a momentous part of human history that we made a SciShow documentary about it. But something that big isn't accomplished by one person's blood, sweat, and tears. There were so many great minds behind Apollo 11's success. So, as we celebrate another anniversary of the triumphant Apollo 11 mission, we recognize Robert Goddard, Katherine Johnson, and Margaret Hamilton for their contributions to Apollo 11 and space travel in general, with a space themed compilation video. While today it's well-known that you can take a rocket to the moon, someone had to come up with that technology. That person was Robert Goddard. Here's Reid, one of our SciShow space hosts, to tell the story of the first rocket scientist. In 1920, when physicist Robert Goddard first proposed that a rocket could one day carry a payload to the moon, none other than the New York Times called him out, saying that the notion of a rocket producing thrust in the vacuum of space without any air to push against was absurd. Goddard's response: "Every vision is a joke until the first man accomplishes it; once realized it becomes commonplace." Born way before the Space Age, in 1882, Robert Goddard is today considered one of the original rocket scientists, although his genius wasn't widely recognized during his lifetime. Goddard didn't invent the rocket itself, but he did build and test the world's first liquid-fueled rocket, the basic design of which continues to be used today. Strictly speaking, rockets are simply devices that obtain thrust by releasing gases at high speeds.
