Okay, imagine you want to go on an adventure trip to space. But you can't just climb into a spaceship and fly off into the unknown, you need to have a special job to go to space.
In Russia, the people who have this special job are called "pilot-cosmonauts." They are brave people who fly spaceships and explore the stars.
Before they can become pilot-cosmonauts, they need to study really hard and have special skills like being really good at math and science.
They also have to be very healthy and fit because being in space can be tough on your body. They need to learn how to work in different environments like zero gravity, where things don't feel the way they do on Earth.
Once they are qualified, pilot-cosmonauts go on amazing adventures, seeing things that most people in the world could never imagine. They can study the stars, do experiments in space, and sometimes even help build things like space stations.
Being a pilot-cosmonaut is an incredible job, but it takes a lot of hard work and dedication. So, if you ever think about becoming one when you grow up, don't forget to study hard and stay healthy!
