To be clear, the composition of the Martian atmosphere is not a secret.
And people had a fairly good idea before going there, obviously: https://en.wikipedia.org/wiki/Atmosphere_of_Mars#History_of_...

My point is China has no probes on Mars unless they have secret ones. They can GUESS what would be best optional frequencies to tune their solar panels for but my point is that they are spending billions of dollars. Do they really want to rely on data they didn’t retrieve themselves? That seems like an odd thing to take a risk on. Better to either work together with nasa since they have the expertise. Hence I’m curious what the relationship is between China and nasa for this project and if it was an open one or if they got the data some other way.
