The Tyranny of the Rocket Equation

And, if your curiosity goes beyond that basic explanation, check out this NASA page on rocket launches:

Chapter 14: Launch

If a spacecraft is launched from a site near Earth's equator, it can take optimum advantage of the Earth's substantial rotational speed. Sitting on the launch pad near the equator, it is already moving at a speed of over 1650 km per hour relative to Earth's center. This can be applied to the speed required to orbit the Earth (approximately 28,000 km per hour).

Getting into orbit doesn't just require overcoming the force of gravity pulling down. In order to stay up, you basically have to put yourself on a path that allows you to go around the Earth faster (or as fast as) you fall back towards it. When your movement around the Earth is balanced with the rate that you're falling, you are in orbit. This means you have to go really fucking fast, not just up but sideways.

Kind of off topic. But people who came up with superheros and such who fly. You always see them going out at an angle and going in at an angle. Do you think they did this much studying or is it just coincidence?
