2 Chinese spacecraft just met up 22,000 miles above Earth. What were they doing?

Editor’s Note: Think of this like a roadside assistance truck meeting up with a car that’s running low on gas—except in space, where repairs or refuels are way harder. If China can reliably service satellites in high orbits (where critical communications and GPS satellites often operate), it could save billions by keeping aging tech alive longer—or, more controversially, manipulate or disable other nations’ satellites. Either way, it’s a big step in the quiet but high-stakes race for orbital dominance.
