In the absence of significant atmospheric drag and with the influence of gravitational forces greatly reduced, astronauts experience the sensation of weightlessness while in space. This phenomenon occurs because both the astronaut and their spacecraft are in a state of constant freefall around the Earth. Objects inside the spacecraft also appear to float, as they are not subjected to the normal force exerted by the Earth's surface. Weightlessness is not only a captivating experience for astronauts but also a crucial factor to consider when designing and conducting experiments in space.
