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.

Do an astronauts weight change in space?

Yes


Why do objects weight change as they travel through space?

Because weight is based on gravity, and gravity changes throughout space.


Does the mass of an astronaut change when she or he is visiting the International Space Station?

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.


Does your weight change if you take a spaceship into 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.


What will change if you go in outer space?

Your weight Oxygen level


How would your weight and mass change if you were floating freely in space?

the weight reduces due to change in gravity but mass remains constant


Do weight change in the space?

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


How do you change weight on earth to weight in space?

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.


When an astronaut is propelled into space does his mass increase or decrease?

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.


Is the weight of the space shuttle the same on earth as it is in space?

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.


Why does the weight of a rocket change while going through space?

It consumes is fuel while flying (although this has little effect as space is a vacuum), the same as an aeroplanes weight changes while it is in flight
