I think they'll either fail to get images of the 'face' and then the
face-fanatics will claim that it's a cover-up, or they'll get images
which show it's natural and the face-fanatics will claim they're fakes
or that careful analysis of single pixels shows that they're still
artificial.

At least 10:1 against; there are many face-like rocks on Earth and I'd
have been very surprised if there wasn't a single one on Mars.
So I think the 'Mars Face' is just a fantasy... the Io Rubber Chicken
