This September, a fake sample appeared in the National Museum of Holland. The Sales of CZ Brooches are Claimed to Make a New Record This Week This aroused the attention of the Associated Press and it initiated an individual investigation tracing the whereabouts of other samples. But unexpectedly, most of the samples are just gone. The explanation of a NASA historian is that NASA transferred the sample to the State Council for the allocation, and we do not have any records that when to send the rock samples to whomever. The Apollo astronauts to the moon can keep a few samples as souvenirs, but only if not used for money, only for handing down from generation to generation.Spring Charm of CZ wedding rings
Nowadays, NASA's left samples are all packaged in Teflon bags and are kept in the helium storage steel cabinet at the Johnson Space Centre in Houston. Any researcher who needs to pick up samples must wear three-layer gloves in order to prevent them from being polluted. Actually, first circles the month the biology is already not the humanity is not an orangutan, but is a pair of turtle. On Nov. 15, 1968, the Soviet Union successfully launched the "probe - 5", which contained a turtle, seeds, bacteria, etc., this is the first time in history, which flight back to earth after completing around the moon.After Zond 5 spacecraft had returned to earth, the animal comrades were retrieved from the Indian Ocean. No injury was found on the turtles' shells. They had, however, lost 10% of their weight, although researchers didn't observe a permanent decrease in appetite. In the theories of interpretation of the lunar evolution, the most successful one is a "magma ocean hypothesis." It believed that the moon had a melt surface whose depth is several hundred kilometers in its early time.In this magma sea, light material increase while heavy material sink.
What is interesting, the scientist discovered that on Moon majority rock magma seas in toward Earth's one side, because at that time was also very near in the place month distance, between both's gravity interaction is intense, when rock magma from the Moon interior overflow, earth gravity immediately its reliable attraction. In 1967, the United States and the Soviet Union drafted out the Outer Space Treaty. The treaty provided that no country would claim the ownership of any celestial body (including the moon). It was strictly prohibited to dispose and use mass destructive weapons in the space. It is prohibited to establish military bases in outer stars (including the moon). Later 97 countries joined the treaty one after another. Today, the word of "extreme climate change" is hot on Earth, but it is insignificance compared to temperature range of the lunar surface temperature. The lowest temperature on the lunar surface is minus 240 degrees Fahrenheit (minus 116 degrees Celsius). However, the temperture can rise to 220 degrees Fahrenheit (about 104 degrees Celsius) in the sunshine. Since the moon has no aerosphere, it cannot reserve part of the heat gained in the day as the earth. However, if you dig 1 m deep hole on the lunar surface, you will find the temperature is always kept at about minus 31 degrees Fahrenheit.
The most successful album of well-known rock band Pink Floyd is called "Moon nightside", But they are wrong, because there is no dark side on the moon. Thanks to that the Moon always faces the Earth with the same side, a part of it always remains unseen by us, but in fact the other side is also "bright". There is no atmosphere on the moon, which means there is no wind, no weather on the monn, also means that the traces of mankind activities is still retained on the surface of the moon.
