HONG KONG — While President Trump refocuses American industry on the earthbound technologies of the 20th century — coal, steel and aluminum — China is setting its sights on the far reaches of the solar system.

China this week launched a rocket headed for the moon, where, for now, only an American flag flies. The Chinese have ambitions to land a spacecraft on the moon’s unexplored far side by the end of the year.

Chinese plans include putting a person on the moon and sending a mission to Mars by 2025. Here’s a look at some of China’s boldest recent endeavors.
