11、and the spacecraft safe, the astronauts must leave and go back to the spacecraft through a special door. When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft.

12、away into space. Another way astronauts stay safe during spacewalks is by wearing a SAFER. The SAFER is worn like a backpack. It helps an astronaut move around in space.

13、uts practice spacewalks underwater in a huge special swimming pool. For every one hour they will spend on a spacewalk, astronauts need to train seven hours in the pool.

14、 only three countries have finished spacewalks independently. They are Russia, the United States and China. The first person to go on a spacewalk in the world was Alexei Leonov from Russia.
