This should be a global effort and I’ve read many articles about the lack of funding for the DSN. It’s getting more and more difficult to “juggle” and do proper time sharing in order to keep communicating with all the existing (and coming) spacecraft.
More resources and funding should be put together, by all space agencies (NASA, ESA, JAXA, ISRO…) so as to continue having means of communicating with all these space probes.
