Did you know? Astronauts in orbit in the ISS or shuttle dont actually feel weightless? The feeling is more like if the shuttle were falling endlessly. They know exactly which way is "down", but the shuttle is moving so fast that the rate of falling is the same rate the shuttle moves to be the same distance farther away from the curve of the earth. Gravity pulls at 32ft/sec/sec. The shuttle moves quickly enough around the curve that the ground straight below is 32ft farther away at the same time. Hence... Orbit
