I'm personally sad to see samples from Jezero crater with potential biosignatures [1] won't find their way back to Earth for the foreseeable future. I was _really_ looking forward to learning more about what we found.

Maybe in some ideal world the US and China would work together to pass those samples on to a Chinese MSR, but it seems borderline impossible.
