Question

Quizplus · Accepted Answer

Astronauts are weightless in the Space Station because the Space Station is constantly in free-fall around the Earth. This results in a feeling of weightlessness, as if they are floating, because they are essentially falling at the same rate as the Space Station around the Earth. This is known as microgravity or zero gravity.
