how come when nasa speaks of the either the space shuttle or the ISS, they speak as if they have left the effects of earths gravity? This is not true. The people in the ISS are falling toward earth at the same speed as the craft around them. When they start their decent back to earth they feel weightless until they touch atmosphere. At that point the atmosphere slows the craft and the people inside feel the G's from that. Are some of the smartest people that nieve to think that we can acually leave the effects of earths gravity, becouse i dont think that is possable.
