All Nearside exceptions previously attributed to meteoritic impacts. This belief now considered incorrect. Two classes of exceptions now distinguished:

(a) Class I Exceptions

Confirmed as meteoritic impacts occurring 50,000 years ago.

(b) Class II Exceptions

Differing from Class I in irradiation history, formation of glasses, absence of impact corroboration and positive results to tests for elements hyperium, bonnevillium, genevium. Example: Crater Lunar Catalogue reference MB 3076/K2/E currently classed as meteoritic. Classification erroneous. Crater MB 3076/K2/E was made by a nucleonic bomb. Other cases confirmed. Investigations continuing.

(4) Farside Subsurface

Intensive sampling from depths approximating that of the original crust indicate widespread nucleonic detonations prior to meteorite bombardment. Thermonuclear and fission reactions also suspected but impossible to confirm.

(5) Implications

(a) Sophisticated weapons used on Luna at or near time of Lunarian presence, mainly on Farside. Lunarian involvement implied but not proved.

(b) If Lunarians involved, possibility of more widespread conflict embracing Lunarian home planet. Possible cause of Lunarian extinction.

(c) Charlie was a member of more than a small, isolated expedition to our Moon. A significant Lunarian presence on the Moon is indicated. Mainly concentrated on Farside. Practically all traces since obliterated by meteorite storm.

LUNARIAN PLANET LOCATED

DID NUCLEAR WAR DESTROY MINERVA?

Sensational new announcements by UN Space Arm Headquarters, Washington, D.C., at last positively identify the home planet of the Lunarian civilization, known to have achieved space flight and reached Earth's Moon fifty thousand years ago. Information pieced together during more than a year of intense work by teams of scientists based at the UNSA Navigation and Communications Division Headquarters, Houston, Texas, shows conclusively that the Lunarians came from an Earth-like planet that once existed in our own Solar System.

A tenth planet, christened Minerva after the Roman goddess of wisdom, is now known to have existed approximately 250 million miles from the Sun between the orbits of Mars and Jupiter, in the position now occupied by the Asteroid Belt, and is firmly established as having been the center of the Lunarian civilization.

In a further startling announcement, a UNSA spokesman stated that data collected recently at the Lunar bases, following research at the University of Nebraska, Omaha, and the UNSA Mineralogy and Petrology Laboratories, Pasadena, California, indicate that a large-scale nuclear conflict took place on the Moon at the time the Lunarians were there. The possibility that Minerva was destroyed in a full-scale nuclear holocaust of interplanetary dimensions cannot be ruled out.

NUCLEONIC BOMBS USED AT CRISIUM

Investigations in recent months at the University of Nebraska and Pasadena give positive evidence that nucleonic bombs have caused craters on the Moon previously attributed to meteorite impacts. H-bomb and A-bomb effects are also suspected but cannot be confirmed.
