What does it take to become a super saiyan in real life?

I would guess about 10 days in a hyperbolic time chamber at 100x earths gravity. I would guess about 10 days in a hyperbolic time chamber at 100x earths gravity.


Why do astronauts feel weightless while in orbit?

Astronauts in orbit are weightless, but not because they are beyond the pull of earth's gravity. If the moon, roughly 240,000 miles away, is within the influence of earth's gravity, so is an astronaut just a few miles up in comparison. Astronauts are weightless because they are in orbit, and being in orbit can be thought of very roughly as a special kind of freefall. They are held by gravity, but they are also moving along a path that keeps them from descending appreciably during their flight. If you remember clips you have seen of astronauts in the space station, floating freely, you can see how futile it would be to try to 'stand' on an ordinary house scale to measure how 'heavy' they are in pounds. But if you could sling an astronaut around on a kind of mass-measuring centrifuge (not too fast, of course) you would see that they are maintaining a healthy mass. Weight and mass are different measures, even if they seem to be indistinguishable on the earth's surface.


How did the astronaut keep from floating away on the moon?

There isn't much gravity in empty space, but there is a great deal of gravity near planets, stars, moons and other celestial bodies. The moon has gravity because it has mass. Everything with mass has gravity (including you, albeit a VERY small amount). That's how the astronauts stayed on the moon, and the reason why their movements were slow because the moon has about 1/6 the amount of gravity as Earth.


Why didnt Felix float when he jumped from space?

Because technically he wasn't in space. He was on the edge of Earths atmosphere. so gravity was still in effect.


How high do you need to go until you leave earth?

To fully escape earths gravity you would have to travel outside of this star system. While outside of our atmosphere you most certainly would feel a lot less of the effects of gravity, you would still be affected by it. Sincerely, Anon Ø

How do astronauts travel in space and escape earths atmosphere?

Astronauts travel in space and escape earth's atmosphere by wearing gravity resistant suits and traveling to outer space in a space shuttle that is insulated against the elements.


What devices do es the space shuttle use to overcome the earths gravity?

rockets


What is the name of the first space shuttle that traveled to earths orbit?

Columbia was the first shuttle to enter orbit. This was the same shuttle that was destroyed during re-entry in January 2003, with the loss of seven astronauts.


What speed does the space shuttle have to reach to escape earths gravity?

17,500 miles per hour puts the shuttle in orbit. BUT the gravity is still there. I'm fact there is about 90% of the gravity while the shuttle is on the ground. That great rate of speed is required to keep the shuttle from falling back to earth. At that speed the shuttle is basically falling around the planet.


Why boosters are used in space shuttle?

Well they are used because without them the space shuttle would not be able to have enough force to escape the earths gravity when it was being launched.


After a shuttle is launched into orbit what happens to gravity?

There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.


How fast does a space shuttle travel in 500 seconds?

To escape the Earths gravity the shuttle goes 17,500 miles an hour. You can use that value to figure out how far it goes in 500 seconds.


What keeps astronauts from being pulled by the earths gravitational force?

Nothing keeps them from being pulled. Earth's gravity certainly pulls on them.


What does a space shuttle use to overcome earths gravity?

A space shuttle overcomes Earth's gravity by using powerful rocket boosters and engines to generate enough thrust to lift the spacecraft off the ground. Once in space, the shuttle relies on continuous acceleration to stay in orbit rather than fighting against gravity.


Why does a space shuttle need to travel so fast when entering earths atmosphere?

Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.


Does gravity affect astronauts?

Astronauts are in a continuous free fall the whole time they are in orbit. You may now ask though, why don't they hit the ground? They never hit the ground because they are traveling fast enough laterally that they miss the earth. In a sense, yes gravity does affect them, that's how they stay in orbit, but they do not feel the affects of it because they are always falling. If you were to sky dive or jump off of a high surface, you would experience the sensation of zero G, you just do not experience the no friction/ airless environment that they do. A quick factoid, when astronauts come home from shuttle missions, from being in the weightless environment for that amount of time, they actually loose some of their muscle mass, in some cases the loss is so great that some astronauts will not be able to walk away from the shuttle once it is back on earth. This is the main concern on future Mars Missions. Being out of earths influence of gravity for months on the trip to Mars can be fatal.


Do the space shuttle have enough fuel to fly to Pluto?

Theoretically yes - although it won't have enough to return. Once out of the gravitational pull of the Earths gravity and a couple of gravitational assists from other planets, a shuttle could make it to Pluto and beyond.
