...series of tests to ensure that they carried no organisms which might be harmful to man. During this time the samples were in complete isolation. Although there have been numerous incidents of isolation chamber leakage, most have been minor. The one major leak occurred during the quarantine of the Apollo 12 samples and required Frondel to enter quarantine for two weeks himself. Failure to find the lunar samples biologically dangerous has led to the quarantine being abandoned...
...Apollo astronauts looked around them, they saw a true desert-devoid of life, devoid of water, devoid of atmosphere (some five per cent of the atmosphere of the moon is man-made). The level volcanic seas or mares of the Apollo 11 and 12 landing sites cover much of the near side of the moon and provided the first lunar samples. Here the volcanic bedrock has been repeatedly hit by meteorites and broken up so that a layer of broken rock and dust from 6 to 20 feet deep lies on the surface. Some of these rocks have been lying...
...history of the moon is revealed by the different types of rock found there. Most of the rocks brought back from the lunar seas by Apollo 11 and 12 are titanium-rich basalt and gabbro. They appear to be once-molten lava from inside the moon which broke through the crust made of lighter anorthosite and crystallized to form the seas about 3.5 billion years...
...crust itself forms the lunar highlands and was crystallized about 4.5 billion years ago-about the same time the earth was formed. Recent Apollo 14 samples from the highlands are anorthositic and support the hypothesis of an anorthosite crust...
SIMILARLY, new information has shaken formerly well established theories about the origin of the moon itself. Before Apollo II there were three main theories of lunar origin: the fission theory envisioning the moon once being part of the earth and breaking away, the capture theory which said the earth's gravity captured the moon as a satellite, and the accretion theory which maintained that the moon was formed by a ring of matter around the earth, similar to Saturn's rings, accumulating to form one body. These theories can now be tested by evidence from the moon itself...
