Every year, tourists visit Hainan for its sandy beaches and blue sea. Besides, there has been a new activity: watching space launches(航天发射).
On 15 November, 2024, thousands of visitors went to Wenchang to watch the launch of the Tianzhou-8 Cargo Spaceship(天舟八号货运飞船). Two days before the launch, rooms at local hotels had already been full.
"In the past, we were very careful about the launch plans. People could only know them on TV after the launches," said an engineer. But now millions of people can watch every launch. The change shows China's growing capabilities(能力) in space technology. Since 2016, the Wenchang Spacecraft Launch Site has had many important launches.
Space-themed tourism also helps other places. For example, the Jiuquan Satellite Launch Center in Northwest China is a popular tourism place. There are space museums, launch towers and astronauts' flats. Xichang also gets a lot from space-themed tourism. About 2 kilometers away from this center, a small village of Yi people has opened many family hotels. Thanks to the space launches, more and more tourists come to Xichang.
