Gaganyaan is like a big spaceship that India is building to send people into space. You know how astronauts go into space in rockets? Well, this spaceship called Gaganyaan will have three Indian astronauts who will live and work in space for a few days before returning back home.
Now building a spaceship is not an easy task, and it takes a lot of planning and preparation. The scientists and engineers who are building Gaganyaan are making sure that the spaceship is safe and can withstand the tough conditions in space. They are also making sure that the astronauts have everything they need to survive in space for a few days.
To make sure everything is in order, the scientists and engineers are testing the spaceship at different stages. They also have to check if the astronauts are physically and mentally fit for the mission. This means that they have to undergo some strict training and medical tests.
Once everything is set, the spaceship will be launched into space. It will travel at a very high speed and cross thousands of kilometers before entering into the Earth's orbit. Then, the astronauts will live and work in space for a few days before coming back to Earth in a special capsule.
Overall, Gaganyaan is a very important project for India as it will not only make our country proud but also help us in learning more about space and its mysteries.
