<u>Astronauts are not weightless during either launch or return to Earth.</u>

<u></u>

<h3>Brief explanation</h3>

Astronauts become weightless when they stop accelerating. Basically that means when the engines cut out and they begin to coast in orbit. They will remain “weightless” for as long as they are in orbit. To get out of orbit, they have to decelerate (i.e. Accelerate in the opposite direction) and so they begin to feel a force that feels very much like gravity as they are falling back to Earth.

One of the cool things is that you can't tell the difference between gravity and acceleration. They're the same thing as far as your body is concerned. Einstein used a variety of somewhat related thought experiments while he has working out the details of the special theory of relativity.

Hence, with this explanation , we can conclude that astronauts are not weightless during either launch or return to Earth.
