After a 24-day journey, Queqiao, the relay satellite for China’s Chang’e 4 lunar mission, successfully entered its Earth-Moon L2 halo orbit.

That’s a problem, because much of the world relies on Russian rockets to get both cargo and people into space. Consequently, we’re now facing the very real possibility of having an uncrewed International Space Station—something that hasn’t happened in nearly two decades.
