The milestones are coming fast and furious for China’s space program.

The robotic Chang’e 5 mission successfully returned pristine moon samples to Earth in mid-December, something that hadn’t been done since 1976. China’s first fully homegrown Mars mission, Tianwen-1, is scheduled to arrive at the Red Planet on Feb. 10. And shortly after that, the nation plans to begin assembling its space station in Earth orbit.
