  Why do astronauts float?

Image: The International Space Station (ISS) is placed in low Earth orbit, at an altitude of approximately 415 km, it circles the Earth in 90 minutes at a speed of 7.7 km/s or 27,700 km/h. The international crew, which is dedicated to scientific research in the space environment, sees about 16 sunrises and sunsets every day.
Astronauts aboard the International Space Station are in a state of weightlessness but not microgravity. ISS and astronauts are in free fall around Earth. This is why astronauts float on the International Space Station.
