How is the spacesuit designed to protect the astronaut outside of a spacecraft?

A spacesuit contains air under pressure to protect from the vacuum in space. It must be designed with a compromise of rigidity and flexibility, so that it does not inflate like a balloon (preventing him from reentering the spacecraft) and allowing him to move and perform tasks.

Why is a rip in the spacesuit is so dangerous?
The oxygen that the astronaut is breathing escapes through that rip (because there is no oxygen outside of the spacesuit, diffusion makes the oxygen spread outside of the spacesuit), and eventually the astronaut dies of oxygen deprivation.the temperature helps to kill the astronaut as well.
To any astronaut what is an Eva?
Extra-vehicular activity, work done by an astronaut away from the Earth and outside of his or her spacecraft
When an astronaut goes on a space walk outside the space station will she float away unless she has a tether hold her to the station or she constantly fires thrusters on her space suit?
It depends upon the situation you place the astronaut in question. A tether is generally used only to act as a life line in case an astronaut starts to come adrift from their spacecraft or station, instead Velcro toe straps and handholds are used to keep astronauts where they need to work. However, this does not answer your question directly so allow me to create three scenarios. Scenario 1: An astronaut leaves their spacecraft and manages to completely stop themselves (although this would both be impossible, or close to it, and would result in the astronaut reentering the Earth's atmosphere) perfectly somehow in the middle of space. From there they will drift away from the space station; simply because they have stopped and the spacecraft hasn't. Scenario 2: An astronaut leaves their spacecraft and, while still orbiting the Earth at the same velocity as the spacecraft, stops moving in any other direction (again this would be near to impossible to achieve). In this case they would not float away from their spacecraft as there is very little force acting upon them and as f=ma (force = mass x acceleration) there would be no acceleration; thus no drifting. Scenario 3: An astronaut leave their spacecraft, and goes to do some work on a part of it from the outside; doing this they touch the spacecraft. Now there is a force being applied and so there would be an acceleration away from the spacecraft. This acceleration could and would be quite small, however with little resistance the velocity of the astronaut would pick up quickly and they would soon find themselves a long way away from their spacecraft. So to reiterate my earlier point, the answer to your question would lie in the senario.
Why do spacecraft have airlocks?
Humans need air to breathe, space is a vacuum so the atmosphere inside the spacecraft needs to be separated from the vacuum outside. Once in a while an astronaut needs to go to the outside of the spacecraft to perform tests or maintenance, and the airlock provides a way for him to go outside without losing the air from the inside. He enters the airlock and closes the door, then all the air inside the airlock is sucked out so it can be used ( air is a precious commodity in space ) then he can open the door to the outside without losing any of it.
In what layer of the atmosphere would a spacecraft be?
A spacecraft would be outside the atmosphere - that is, it would ideally be at such an altitude that there is no longer any significant atmosphere.

What does spacewalk mean?
A spacewalker is an astronaut who goes outside of the spacecraft while in space. This is called extravehicular activity (EVA) and is usually done to perform inspection or repair of the exterior of the spacecraft.
What do you walk on in space?
A "space walk" does not refer to actual walking. Extra-Vehicular activity, or space walk, refers to work being done by an astronaut outside of the spacecraft.
What is space walk?
It's called a space walk when a astronaut is "walking" outside her spacecraft in outer space. see wikipedia for more info: http://en.wikipedia.org/wiki/Space_walk

Why can't you go outside without a spacesuit on planet Saturn?
There is no oxygen you would die.
Would you able to go outside without a spacesuit in Pluto?
No because Pluto doesn't have any oxygen.
What is called a person who travels outside the atmosphere of the earth?
An astronaut
Where does Apollo appear outside of mythology?
He gave his name to spacecraft.
