Depends on where the astronaut is.
If you're thinking of the moon, then an astronaut can jump up and down because there is gravity on the moon. It's just not as strong as on earth, so the astronauts can jump higher and farther.
If you're talking about in deep space, or aboard the international space station, then the astronauts are not really jumping. They are pushing off the floor or walls, and will keep flying in the direction they pushed until they hit something or grab on to something.

What do astronaut beds look like?
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.
Can Astronauts jump high on the moon because the moon has less mass than the earth?
Yes, astronauts can jump higher on the moon than Earth because there is less gravity on the moon than on Earth. The Moon's low mass causes a force of gravity at the Moon's surface that is only about 1/6 of the force of gravity at the Earth's surface. A fully-equipped astronaut who weighs 270 pounds on Earth only weighs 45 pounds on the Moon. They must be careful though because their 123 kilogram mass is the same as on Earth, which means it is just as hard to speed up and just as hard to slow down; they must avoid the temptation to think that their reduced weight gives them reduced mass, which it doesn't.
How does an astronaut travel up into space?
Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit.
How does the Moon's gravity impact the earth?
The moon's gravity creates high tides and low tides. The moon's gravity pulls the water up and down as it orbits the Earth.
Where exactly is gravity is it up or down?
A better description would be that it's between. Gravity is a force that exists between any two masses.
If there is no gravity on the moon why can an astronaut jump up and down as seen in the space shots?
There is gravity on the moon. There is less gravity on the moon than there is on earth, because the moon is smaller than earth. Because the Earth has the mass it has, it has the gravity it has. Because the moon has a lot less mass than the Earth its gravity is about 1/6 the amount of the Earth's gravity.
What does the law of gravity explain?
No matter what happens what goes up must come down. For example if you jump up into the air you have to come down because of the force of gravity. Same for space travel. If you jump on the moon you must come down.
What is the easiest physical property to observe?
density GRAVITY , JUMP UP AND SEE IF YOU DONT COME DOWN
How Is Gravity Involved With Dance?
It affects all jumps and leaps, causing the dancer to come down to the floor. Any attempt to appear to float graciously in the air is short because of the force of gravity.
How can you fight gravity?
you jump up high and float
When was Jump Up Jump Down Live created?
Jump Up Jump Down Live was created on 2000-04-17.
Why is there gravity on earth but there is no gravity in the water?
The reason why is because of air. Air is just made up of atoms and gravity works on holding down mass and air has no mass. Where water is a liquid and has mass so gravity holds it down. So when you jump in the water you have less mass then the water does so gravity does not work on you when in the water.
Can a skunk jump down?
No they can not jump up and down. I hope I helped you!
How is speed affected by gravity?
Gravity acts as a barrier and slows it down. However, if you say, jump of a building. When you fall gravity will speed you up and you'll be dead fast. When you fall your speed is about 78mph. But that depends on the height of the building and wind direction.
Could you jump up higher on the Moon or on Earth?
You can jump higher on moon,because there's less gravity.
What jumps but never falls?
anything that can jump but ON A PLANET WITHOUT GRAVITY!!!!!! Also in space where up could be down and down could be up. If a person jumps into a volcano the person will vaporize and the air particles will float upwards and possibly float into outer space where there is no up and there is no down.
Is it fun to jump up and down?
Yes jump and jump untill you bump your head and be dead:):):):):):)
