Falling into Orbit

Here is a funny little space factoid Craig Damlo made for Yuri's Night.
I laugh out loud every time I read it...


Falling into Orbit

The Hitchhiker's Guide to the Galaxy has this to say about flying: "There is an art to flying, or rather a knack. The knack lies in learning how to throw yourself at the ground and miss. Clearly, it is this second part—the missing—that provides the difficulties." Although mankind may never fully learn to fly, we have become very proficient at falling. And on April 12, 1961, Yuri Gagarin became the first man to miss the ground.

That is all there is to space travel—falling, continuously falling. In the simplest of terms, a space launch works like this: take an object—in this case a space capsule—and throw it toward the horizon; if you throw it far enough, it simply will miss the ground as it falls back to Earth, and will enter an orbit around the planet. This may be, in fact, the greatest benefit of living on a round planet—well, that and the stability and strength of a sphere.
