Is it true that an astronaut is weight in space Explain answer?

Yes, it is true that an astronaut's weight in space is effectively reduced due to the microgravity environment. While mass remains constant, weight is the force of gravity acting on that mass. In space, particularly in low Earth orbit, astronauts experience free fall, creating the sensation of weightlessness, even though gravity is still present at about 90% of its strength compared to Earth's surface.
