As an astronaut goes out into space (not on another planet but in space), her mass _______________ and her weight ____________________.

Answer 1

As an astronaut goes out into space, her mass remains constant, and her weight becomes effectively zero.

Mass is a measure of the amount of matter in an object and does not change regardless of location. Weight, on the other hand, is the force exerted by gravity on that mass. In the microgravity environment of space, the gravitational pull is significantly weaker than on Earth, which results in the astronaut feeling weightless.
