Miniature Apollo Mission
Part of me thinks that the coolest thing about the Chang'e 5 mission is that it's essentially a step-by-step retread of the Apollo missions, only in miniature (well, a bit smaller). One major change being that they didn't have to do the weird flip of the lander with the command module before reaching lunar orbit as was the case with the Apollo missions.
It's also great to see the Chinese space agency working together with ESA on the tracking of the mission, while providing more live coverage of the launch and landing than ever before. It's a good sign of less paranoia and distrust from both sides.
