The far side of the Moon is a hard place to operate for one stubborn reason: the Moon itself blocks your radio line to Earth. Every space power had looked at it and filed it under someday. In 2019, Chang'e 4 solved it the direct way — China first parked a relay satellite at a gravitational balance point beyond the Moon, then landed in Von Kármán crater and drove the Yutu-2 rover out onto ground no machine had ever touched.

Five years later Chang'e 6 went back and did something harder: it brought far-side rocks home. Nobody else has returned a gram from that hemisphere.

Mars punishes beginners — more than half of all missions ever sent there failed, and every previous nation's first try ended in some flavor of grief. Tianwen-1 arrived in 2021 carrying an orbiter, a lander, and a rover, and all three worked. The Zhurong rover drove across Utopia Planitia for a year, making China the second nation ever to operate a rover on Mars.

The mission's name comes from a classical poem — "questions to heaven." The engineering answered several.

When the ISS partners declined Chinese participation, China built its own. Tiangong went from first module to completed three-module station between April 2021 and November 2022 — a construction pace the ISS never approached — and has been continuously crewed since. It flies lower and lighter than the ISS: about a fifth the mass, one national program instead of fifteen.

The station is the visible tip of a deeper system: the Long March rocket family has flown hundreds of missions, and China now launches more times per year than any nation except the United States.
