It is decades long undertaking and defy the boycott of the western world but finally it gets done
At cost of 12 billion USD but it also advances Chinese space and high-tech GPS related technology and ecosystem All in all it is good investment. After being rejected by EU consortium and refusal to return the invested money what a sweet revenge

Do you know the reason for not returning the money thanks?

As far as I know, the European Commission never gave an answer to this question raised directly by Chinese officials.
I guess it was hubris, and " what can you do about it even if I poke you in the eyes " attitude, because the Europeans simply did not believe China could build their own system by herself ahead of the Galileo.
Now we know better, and indeed it is sweet revenge, haahaahaa.

Are the dark grey extensions, at the base of the hopper, wheels? If it is, it'll improve its capability tremendously.
Interesting observation. It seems that the hopper is hexagonal, 6 landing legs, 3 pads and 3 seemingly wheels. It won't have the mobility as a rover, but certainly can move a short distance when doing inspection, drilling etc.

Edit, after reading by78's post 5404, I think that is also a good possibility, 3 landing pads and 3 hopping thrusters.

Do you mean thrusters mounted on some of the legs?
I imagine 6 legs, 3 with pads, 3 with thrusters (also appears like wheels)
Oh no, I was being facetious. Although, given the Moon's reduced gravity, it's probably doable to have it hop around by actuating its legs.

It'll definitely use some kind of thruster(s) for hopping probably to longer distances. I imagine using wheels for shorter distances would be the most energy-efficient, if those are indeed wheels, after the longer distance hopping maneuver.

Hopping using some kind of spring or hydraulic would require a lot more energy reducing fuel efficiency and you won't know exactly how it would land. :D

the side mounted thrusters (for horizontal maneuver) are clearly shown. so the main lifting thruster is almost certain to be chemical thruster (rocket).

However, a spring or hydraulic system can use electrical energy (a mini EM launcher) which is unlimited, if there is access to solar panel and sun light. That is energy self-sufficient.
