A group of six people spent a year in a fake moon mission to help us learn about space travel. They lived in a special place on Earth like they were in space. The project was called SIRIUS-23, and it tested how people would do on a real mission to the moon or beyond. The crew did different tasks to see how they would work in space. They also wore special suits and did experiments to study their health. The goal was to learn how to keep astronauts safe and healthy on long space trips. The crew members were from Russia and Belarus, and they worked together to solve problems and complete their tasks. They even pretended to walk on the moon using virtual reality. The project also studied how being far from Earth can affect people's minds and bodies. After a year, the crew finished their mission and had to adjust to life back on Earth. They went to a resort to relax and enjoy the things they missed while in isolation. The success of the SIRIUS-23 mission brings us closer to exploring space for longer periods. By learning from this project, scientists hope to send humans to the moon and beyond. It was a big step towards making space travel safe and possible for everyone.
