Where does that cost number come from? Data processing? Personnel cost?
The bird is already out there, so there's no cost there.
Is there any mechanism for sponsoring it?
They have to operate the large dish antennas, data collection and reduction facilities and the continual spacecraft control. Neither Der Orange Führer nor the fanatic creationists who are supporting him understand science, and since it does not confirm their primitive flat earth views, it is on their list to eliminate spending on it altogether. Electrical power to the antennas could be used for something more useful, like mining for the “$Trump” meme coin. /S
PS: Ninja'd. See the mperrin response above for a more exhaustive list.
