WHY do people still believe Hoagland?
The man has been shown to be a fraud, countless times. His BIG success was selling a book, BEFORE the advent of the Internet, BTW....
Anyway....early photo of Cydonia, has been shown to be a peculiar moment in time, caught in an image, and just a play of shadows that allowed the
HUMAN BRAIN to interpret it as a "face"....Of course, people have NO IDEA the scale of the region...it's like seeing a satellite image of, say,
ICELAND and thinking it looks 'manufactured', just because of the shadows.
Further images (under different lighting conditions) show a different perspective, on a very benign, and completely natural, formaiton:
A definitive picture of what was called the "face" on Mars, at Cydonia:
An earlier question about 'pyramids', by an ATS member (forget who, sorry...)
Same answer, I believe.
Perception, of photos from orbit, with little size comparisons to relate to what's familiar with Earth photos.
AND, a big dose of speculation thrown into the mix....
Interesting. Speculative, at the most.
That sort of 'aircraft', as depicted in the artist's rendering? Well, from what I understand about the very, very thin atmosphere of Mars, not
bloody likely to be a sustainable airfoil (not unless the vehicle is a LOT lighter, in terms of manufacturing and components/materials used) OR it
utilizes some sort of OTHER technology, not yet made public...
The fact that it tries to convey an aerodynamic concept, though, tends to diminish its credibility, knowing what we know about the Mars biosphere.
I will direct people's attention to various KNOWN aircraft that actually are designed, and proven to operate, in earth's atmosphere, at very, very
high-altitudes (thus simulating the very thin atmosphere of Mars).
The U-2, for instance. AND, though they do NOT operate in very high altitudes, look at unpowered gliders (sailplanes) for some guidance into wing
design, as in: Lift-over-drag coeffiecients, with very long-aspect wing ratios, and such. VERY important design considerations to maximize lift
ability in very thin atmospheres.
In short: I think that image, as depicted by some "conceptual artist", is pure fantasy, and not scientifically accurate.
