The reason an astronaut in an earth satellite feels weightless is that the astronaut is beyond the range of the earth's gravity. the astronaut is falling. the astronaut is at a point in space where the effects of the moon's gravity and the earth's gravity cancel. this is a psychological effect associated with rapid motion. the astronaut's acceleration is zero.
