(If the Moon's gravity were not tugging on them, they would gone sailing right on past it!) But because they were drifting in space, they were basically in freefall -- their spacecraft was being tugged exactly the same as they were, so they were not actually aware of the Moon's gravity.<br /><br />Astronauts experience the same thing in Earth orbit, as shuttle_guy said. They are deeply in the influence of Earth's gravity, but they do not actually feel it. This is because you don't feel gravity itself -- you feel changes in acceleration thanks to the way your body senses up and down. If you're in freefall, there is no change to feel. You can experience this yourself the next time you visit an amusement park. Pay close attention during the first big drop on a roller coaster. It's not completely zero gravity, but it's close enough to get the idea. You aren't actually experiencing less gravity, but you still get lighter. This is because the roller coaster is dropping at the same rate that you are.<br /><br />Your body weight is really just the amount of force your body applies to the floor. If the floor isn't dropping, you'll be pressed against the floor by gravity. But if the floor is dropping at the same rate that you are, you won't press against it at all and you will be weightless!<br /><br />And welcome to Uplink! <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
