Spacewalks are amazing - the astronauts are exiting through a port door into outer space from a space station which is whirling around the earth at a speed of 27,000 kph (around 17,000 mph). Imagine climbing out through the roof of a car which is travelling around a race track at around 400 kph (around 250 mph) and trying to repair a broken radio antenna, or something like that!
