If the size of the space station is large enough, then the astronaut will detect the change in Earth's gravity (g).
Yes there are people in space station orbiting earth.
If he is aboard something that's in Earth-orbit, like the International Space Station or the Space Shuttle, then Earth's gravity is what's keeping him in orbit.
The International Space Station
Since there is no gravity to hold astronauts in their beds they have to sleep in zipped up sleeping bags that are strapped to the inside of the space station, space shuttle or whatever they are in.
the International Space Station
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
It arrives directly from the sun or comes in via the reflection off the earth, the moon, or anything else orbiting nearby.

When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
Yes. Mass and weight are different quantities. The mass of the astronaut is always the same everywhere. The weight of the astronaut is the force on it due to gravity, which depends on the mass and the strength of gravity at the point on the planet, moon or space station the astronaut is standing on. The strength of gravity is known as "local acceleration due to gravity", and it is represented by the letter g. On the surface of the earth g is about 9.8 ms-2. On the surface of the moon g is about 1.6 ms-2 (a 6th that of the earth). On a space station, because the mass of the station is so small, g is effectively 0 ms-2. So, the weight of an object is the force on it due to gravity. The formula for weight is: W = mg Where: W = Weight (in Newtons) m = mass (of the object, in Kg) g = local acceleration due to gravity (in ms-2). Hopefully you see this formula is a restatement of F = ma. Your average man has a mass of about 70 kg. If you plug in the numbers you find the weight on the earth is 686 N, on the moon is 112 N, and on the space station it is 0 N (i.e. the astronaut is totally weightless).

The first orbiting space station was Salyut 1, launched by the Soviet Union in 1971.
an astronaut is someone that goes up in to space
The United States Skylab is an orbiting space station. It is basically used to experiment in the adaptation of humans to zero gravity. Other experiments are also being carried out.
