False.Orbiting astronauts feel weightlessness since the gravitational pull of the Earth is balanced by the centrifugal force due to the circular orbital motion, which balance each other out since the spaceship is in orbit. That is, the weightlessness is because of no net force on the astronaut.In a nutshell, if you are orbiting, then irrespective of what height you're doing it, you'd be weightless.


Astronauts in orbit experience weightlessness due to their motion around the Earth.


You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.


Weightlessness occurs in space. Astronauts circling the earth in space experience the feeling of weightlessness.


earth For some of the images taken by astronauts of what they see, check the Web Links to the left.


The fact that he is orbiting means he is being held by the gravitational force of the Earth. If not for that, he would be headed out of the solar system.



An object in free-fall anywhere is "weightless". Something that is orbiting Earth is in free-fall.



You have to be outside of the gravitational pull in the atmoshpere. Answer: Weightlessness can be achieved:* in Earth's atmosphere in an aeroplane doing a dive or on carnival rides (Drop of Death)* when in orbit around the Earth or other body.* there are several points (Lagrange points)in the Earth/moon system where the gravitational attraction of the two bodies cancels out producing weightlessness.


An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.


because they are falling through space.


No. Edit: It depends on the definition. They are still easily within the Earth's gravitational field, so in that sense they are not weightless. However, they do "float about" inside the spacecraft because they are in effect falling freely in the gravity field. In that sense they experience "weightlessness".


John Glenn made America's first orbital flight on February 20,1962. The Russians beat us to it, but John Glenn was the first astronaut.


An astronaut in orbit around the earth on the space shuttle or space station experiences near-complete weightlessness, because the shuttle is travelling fast enough around the earth (28,000 kmh) that it remains in orbit, constantly falling under the influence of the earth's gravity, but never reaching the earth. The 'free fall' causes the effect of weightlessness.


Yes, all of them. They just all happen to be buried on the third rock orbiting the sun.AKA the earth


while the earth is orbiting the sun the moon is orbiting the earth


Consider an astronaut that has a mass of 70.0 kilograms (154 lbs) who is traveling to space. At the moment of blast-off the weight of the astonaut is also 70.0 kilograms. As his distance from earth increases and the rocket turns into an orbiting course, the gravitaional pull on the astronaut's body decreases until a state of weightlessness ( 0 lbs). However, the mass stays the same because it's independent to both locations and unvarying quantity.




The largest satellite orbiting the Earth is the Moon.


Earth orbiting the sun is a planet that is attracted to a star.


the sun reflects the light to the astronaut eyes so the astronaut can see the Earth .


Weightlessness is a measure of how much resistance there is between an object and the local gravity. If you are standing on the ground, then there is 100% resistance between you and the pull of gravity. Your weight is equal to the pull of gravity on your mass. When you jump off a tall object, you are falling. You feel weightless because there is no resistance between you and the pull of gravity. When you are in a shuttle orbiting the Earth, both you and the Shuttle are falling in such a way that you never hit the ground. This is called an orbit. You feel weightless because you are falling. You just never hit the bottom like you would on Earth.


It arrives directly from the sun or comes in via the reflection off the earth, the moon, or anything else orbiting nearby.
