Yes it does! Because of the gravity on earth we get pulled down, but in space there ain't anything like this, so we all weight 0kg

Yes
Because weight is based on gravity, and gravity changes throughout space.
The mass of an astronaut does not change when she is visiting the International Space Station. Mass is a property that does not change, but the weight of a person does change in space.
Your weight does not technically change when you go into space, as weight is the force exerted on an object due to gravity. However, in space your gravitational force is reduced (you are in a state of freefall), so you experience the sensation of weightlessness.
Your weight Oxygen level
the weight reduces due to change in gravity but mass remains constant
To calculate weight in space, you would use the formula: Weight in space = Weight on Earth x (gravitational pull of space / gravitational pull of Earth). Since gravitational pull in space is typically much lower than on Earth (about 0.17 times that of Earth), your weight in space would be significantly less. Keep in mind this calculation assumes a constant gravitational pull throughout the region of space you are in.
The mass of an astronaut in space does not change, except for the minor changes that occur due to change in exercise and eating. Mass is mass, and represents the amount of material in an object. His weight, however, does change, because weight is mass times the acceleration due to gravity, and gravity does indeed change.
Because there is almost no gravity in space. When a person is in orbit just outside of earth, the outward acceleration will cancel out the force of gravity, giving a person zero weight.
Its mass is the same(ignoring spent fuel) but the weight is a result of the gravitational pull, which is different in space. Actually the space shuttle never gets far enough from the earth for it's weight to change. The reason it seems weightless is because it is in free-fall.
Your weight is less on the moon b/c you have less gravity that pushes down on you in space--and in space there is no gravity,its a big vacuum and your mass is whats inside you.
