Astronauts experience weightlessness in space because they are in a state of free fall while orbiting Earth. The spacecraft and the astronauts inside it are moving forward at high speeds, creating a continuous free-fall condition around the planet. This means that both the spacecraft and the astronauts are falling toward Earth due to gravity, but because they also have a significant horizontal velocity, they keep missing it, resulting in a sensation of weightlessness. This condition is often referred to as microgravity.
In space, there is no gravity and one would experience weightlessness.
Weightlessness is the effect that astronauts enjoy in space.
Astronauts on the International Space Station (ISS) experience weightlessness because both the station and the astronauts are in a continuous state of free fall towards Earth. While they are still under the influence of Earth's gravity, the ISS travels at a high horizontal velocity, creating a balance between gravitational pull and the centrifugal force due to its orbit. This results in a sensation of weightlessness, as everything inside the station, including the astronauts, falls at the same rate. Consequently, they float relative to the station, leading to the experience of microgravity.
Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.

Having neutral buoyancy underwater simulates the weightlessness the astronauts will experience in space.

Astronauts in orbit experience weightlessness because they are in a state of continuous free fall towards the Earth. This creates the sensation of floating in space, as there is no force pushing against them to create the feeling of weight.
Astronauts In space experience weightlessness. It commonly is referred to as zero gravity.
Astronauts want to be one of the few people who get to go into space, to experience living in a weightlessness environment, to look down on the earth from above, and to fully appreciate the vast emptiness of space.
Weightlessness.
If astronauts don't exercise in space, weightlessness eventually causes there muscles to shrink?

You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
