Today, we celebrate the ninth "China Space Day" together and look back at the magnificent launch of Dongfanghong-1 54 years ago, which was the starting point for our exploration of the universe.  Surveying the sky, exploring the universe, and asking the firmament, Shenzhou 18 is now ready to go.  The world's first on-orbit study on plant stem cell function and the country's first on-orbit aquatic ecology study are about to begin. "Space tourists" are expected to become a reality in the future. This indicates the infinite possibilities of space life in the future, and the Chinese nation will also achieve new heights of flight.
