Thriller spacewalk of astronauts

Astronauts who travel in space wearing a special type of space suit while sitting in a spacecraft sometimes go for a stroll outside the spacecraft. This is called spacewalk. However, they do not have to be this way to get around. There are also important tasks. Atlantis astronauts recently stepped out of the spacecraft to repair the space station from the outside and stayed in space for 3 hours. In an atmosphere without gravity and air, the astronauts floated in the air and carried out various spare parts repairs outside the space station. No wonder they don't even feel the weight of the spare parts in their hands!
