A spacewalk is when an astronaut goes outside their spacecraft and floats in space.
Spacewalks are very exciting and dangerous. They make people think of astronauts and space exploration.
Examples:

I want to do a spacewalk when I grow up.
During a spacewalk, astronauts wear special suits.
I hope I can do a spacewalk in my lifetime!
