First of all the low gravity decreases all the muscle tone inside the astronaut. They find themselves unable to keep their food down in zero gravity. Then their is time. Time goes faster for them as they are away from the earth. It is because they are away from a earth a heavy body. Im not going to explain this in details as the answer is not for this question.

Does it take 27 days to orbit the earth?

That comes roughlyclose, if you happen to be the moon. Astronauts orbiting the earth make several orbits per day.


Why does astronauts appear weightless in their earth orbiting space craft?

Astronauts appear weightless in their Earth-orbiting spacecraft because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the spacecraft is moving forward at a high velocity, it is also falling towards the planet due to gravity. This continuous free fall creates a condition known as microgravity, where the effects of gravity are still present but are not felt by the astronauts, making them seem weightless relative to their surroundings.


Are there people in the space station orbiting the earth?

Yes, the International Space Station (ISS) typically has a crew of astronauts on board conducting scientific research, maintaining the station, and performing other tasks. The crew size varies but usually ranges from 3 to 6 astronauts.


Why do astronauts float when in a orbiting space ship?

Astronauts float in an orbiting spaceship because both the spacecraft and the astronauts are in a state of free fall towards Earth. While the ship is constantly falling due to gravity, it also has a forward velocity that keeps it in orbit, creating a sensation of weightlessness. This condition is often referred to as microgravity, where the effects of gravity are still present but not felt in the same way as on the Earth's surface. As a result, astronauts appear to float relative to the spacecraft.


Free fall explains why astronauts have no mass while orbiting Earth?

Not quite. It explains why they have no weight. But their mass doesn't change.It's the same on earth, on the moon, and everywhere in between.


What is the name space station that is orbiting the earth now?

The space station currently orbiting Earth is called the International Space Station (ISS). It serves as a research facility for various countries and is inhabited by astronauts from around the world.

When are astronauts in free fall?

Astronauts are in free fall when they are in a spacecraft that is orbiting Earth or another celestial body. In this state, both the spacecraft and the astronauts inside are falling towards the planet due to gravity but also moving forward at a high speed, creating a continuous state of free fall. This results in the sensation of weightlessness for the astronauts, as they are in a constant state of falling around the Earth rather than towards it.
