    What is a spacewalk?

    A spacewalk is when a person in space has to put on a spacesuit, open the airlock, and step outside into the vacuum of space. There's usually no real "walking"; just a whole lot of floating and bouncing around. A spacewalk can be pretty hazardous, seeing as how the person performing the spacewalk is no longer in a controlled, breathable atmosphere and they are exposed to all sorts of radiation streaming outward from our sun. Without the protection of Earth's atmosphere, astronauts have to be very cautious when doing a spacewalk and their equipment undergoes a lot of rigorous testing to ensure that the spacewalk itself goes smoothly. Do NOT, under any circumstances, perform a spacewalk unless you are trained to do so.

    Astronauts can leave the spacecraft to collect samples from atmosphere and conduct some scientific experiments outside the spacecraft. In order to survive in the outer space, he needs oxygen, electrical power and communication which will be supplied to him through a supply pipe. Of course he should return to the spacecraft without any harm.  Really it is not a walk but moving in the vacuum is known as 'spacewalk'. Before venturing in to the sky he will be trained in 'space walk'.
