Tianwen-1 is a spaceship that was built by the country of China to explore a very far away planet called Mars. It is like a big robot that has many different tools and cameras that can help scientists learn more about Mars.
Tianwen-1 was launched into space on a big rocket, and it had to travel a very long way to reach Mars. It took about seven months to get there! Once it arrived, it started orbiting around Mars to take pictures and gather information.
The spaceship also has a special robot called a rover that can drive around on Mars and collect samples of rocks and dirt. It has a drill that can dig into the ground and a camera that takes pictures of everything it sees.
Tianwen-1 is very important because it can help us learn more about Mars and whether or not it might be a good place for humans to visit or even live one day.
