Which statement most accurately describes why the astronauts feel weightless on board the ISS? Remember that gravity is what holds the ISS in orbit. Since the ISS is under the influence of gravity alone, it is in a state of continuous freefall as it orbits Earth, resulting in an apparent weight of zero. Since the ISS is in space (outside of Earth's atmosphere, there is no force from gravity so gravity does not act on objects inside the ISS, including the astronauts.arrow_forward
