@kevbo, we have large spacecrafts photographing every possible aspect of Mars, and the moons of Jupiter, and many of the other planets. We have views of things from far out in the galaxy, and views of nearly every planet in our solar system. The moon is is our closest neighbor, we know more about it than any other heavenly body, yet what are the odds we missed something when we took all those pictures and readings of it over the years? We missed mining industries? I bet we missed the little green men having sun and sand beach parties on the Sea of Tranquility, too.
Hoagland and the Face on Mars conspiracy? Surely you can’t take a loon like that seriously. The face on Mars has been proven by more recent photos as simply a trick of the light. Haogland is a wackjob, no skepticism needed.
