His writings claim that advanced civilizations exist or once existed on the Moon, Mars and on some of the moons of Jupiter and Saturn, and that NASA and the United States government have conspired to keep these facts secret.
Hoagland claims the "Face on Mars" is part of a city built on Cydonia Planitia consisting of very large pyramids and mounds arranged in a geometric pattern, with the ratios between measured angles roughly equaling mathematical constants such as pi (π), e, as well as the square root of 2 (√2), the square root of 3 (√3), and the number 3. He states that the ratio between the surface area of a sphere and the surface area of the tetrahedron inscribed within it, ≈2.720699, which is π × (√3)/2, is an approximation of e that he refers to as e'. Since e'/π = (√3)/2 = ≈0.866, he speculates that the primary meaning of the geometry of Cydonia is to emphasize the ratio of the sphere and circumscribed tetrahedron. To Hoagland, this is evidence that an advanced civilization might once have existed on Mars, and that NASA is suppressing the evidence for reasons explained in a 1960 Brookings Institution report entitled "Proposed Studies on the Implications of Peaceful Space Activities for Human Affairs."
In March 2010, Mars Express returned radar and visual data from Mars' larger moon, Phobos, showing the moon in unprecedented detail. Hoagland wrote that Phobos was revealed to be artificial, a "manufactured" satellite.
Hoagland rejects the entire body of knowledge represented by professional selenology and asserts that there are large semitransparent structures constructed of glass on the lunar surface, visible in some Apollo photography when the images are digitally manipulated, and even more so when old photoprints are re-scanned on amateur equipment in non-clean conditions. He goes on to say that NASA is suppressing knowledge of an ancient civilization on the Moon, and that the advanced technology of this civilization is lying around on the Moon's surface.
It is Hoagland's opinion that NASA's two Gravity Recovery and Interior Laboratory (GRAIL) spacecraft were sent to map the gravitational field of the Moon to confirm the "presence of actual engines inside the Moon." Based on his examination of earlier NASA lunar seismic data, he said that he found "symmetrical structures under the lunar surface at the depth of the core of the Moon." Moreover, he said that the "Moon is not ours" and that it was "brought here and placed in orbit" around the Earth.
Hoagland claims the United States government has covered up the presence of extraterrestrials, that the Space Agency[who?] murdered the Apollo 1 astronauts, that NASA missions to Mars are a "well documented interest of the Bush family," and that there is a clandestine space program which uses anti-gravity technology reverse-engineered from lunar artifacts and communicated by secret societies.
The two Soviet scientists Vasin and Shcherbokov, and David Icke, and Alex Collier all confirm that the Moon is artificial and came from somewhere else.
