Description:

Connecting two living spaces is a very challenging task. It’s easy enough to grab onto something in space with a clasping hand or twisted tethers around a knobbed pin, but how the heck do you secure two hollow structures? Any docking or berthing mechanism must have plenty of room right in the middle for crew and cargo. That’s a tall order. Also, Hayabusa II, EFT-1, Ariane 6, Venus Express and New Horizons!
