Astronauts still weigh 65 kg. Mass is constant or does not change anywhere.
A person's mass is constant whether he is on Earth or on the Moon because mass is an essential property of matter. There is no difference in the mass of astronauts on Earth and on the moon. Mass is a constant value, but a person's weight varies depending on their position on the earth.
Weight is the downward force exerted on a person or body by gravity. Whether measured on Earth or on the ISS, the mass does not change. Weight may change due to gravitational forces such as B. On the moon, the weight is reduced to one-sixth of what it is on Earth. Astronauts and their spacecraft still have mass and are subject to Earth's gravity.
