The beginning of the odd differences between the nearest and far side of the moon is a step to solve, thanks to the newly found from the spa pole-aitken (spa) basin.
The near side of month familiar with us as only a part to see WORLD. The dark regions called Mary are many plains of lava filling fruit jars, and gives us the standard of “man of the moon. “Yet the far side of the moon, which can only be seen by orbiting spacecraft, has barely any maria and is covered by craggy, cratered and ancient highlands. That’s not the only difference between the two hemispheres; the thinner on the near side, Volcanic Activity Appears to have occurred at different points in time, and the mantle beneath The far side seems to be overdue with some elements as compared to the near side.
However, as we have many samples from the lunar near the side, especially the world brought to Apollo Missions, Soviet Luna and Self missions in China Chang’e 5We are not from the far side where theories are.
Then, on June 2024, China’s Chang’e 6 missions Landed on Spa basin and brought back samples worth 1,935.3 grams (68.27 ounces).
The spa basin is the biggest effect of the month of the month, which has been with 2,500 miles (1,600 miles) and from the Lunar South Pole and the far side of the month. It is also the oldest known part of the month effect, with the age of 4.25 billion years. What impact – pardon the pun – can the greater violence in the form of spa basin may have in the lunar geology and the thermal evolution of the interior? Can this cause dichotomy between the two hemispheres of the month?
Chang’e 6 samples were first from Lunar Fares, and gave a unique opportunity to try the models that could mean the difference between the two hemispheres of the month.
As a result, following analysis of samples, researchers led by a team from the Chinese Academy of Sciences with four major discoveries.
The first is that samples consist of sample volcanic stones called basalts date of long volcanic eruptions in two distinct parts of two 6 years ago and another 2.
“We suggest that 4.2-billion-year-old basal intensification of Spa Basalt, which requires the Geology of Geology and Geophysics in the Space Academy in an email interview. Lunar Magma Sea. “
The evolution of this Lunar Magmace Ocean forming the mantle of the moon is the basalt analysis center in a coffin source under particular elements such as thorium. Don’t know if the touched mantle is found only under the spa basin, or if it is greater than the moon.
“To be honest, we do not know,” says Yang.
One possibility is that the moon gets the mantle from birth, where all close and far should share this composition. Another possibility is that it was done after the lunar magma was formed and began cleaning the crystal.
“Personally, I strongly believe that the latter, given that such an impact has the potential to affect the mantle of a depth of 250 kilometers (155 miles),” Yang said. “If it’s only at the spa basin, then it should be formed as a result of the spa effect. We need to take a lot of samples from outside spa areas.”
The third discovery is something we can’t expect to see in the moon: water. However we are talking about – million here – the Apollo The samples are considered “dry bone,” and the far side of the foot as the greater.
“The water content of this mantle is lower than the mantle sources of all basalts from nearby,” Yang said.
The final discovery relates to the moon’s magnetic field. The natural satellite in the world today does not have a global magnetic field, and magnetism traces will only remain in some anomalial patches called Lunar Swirls. However, in the distant past it has a global magnetic field. Chang’e 6 samples remained a record, and show that the magnetic field, after being decayed at a time, changed strength about 2.8 billion years ago. It indicates that the internal dynamo of the moon changes, can be episodically, instead of just getting into a slow but slowly reduced.
The time in accordance with the second round of volcano on the distal side.
“The magnetic field revounged 2.8 billion years ago, suggesting that the moonlight still has strength,” Yang said. “Perhaps attention and the upward flow of hot material exists in the lunar mantle at the time.”
Not only is this flow flow that prompts volcanic eruptions, it may be enough to vaporize most of the water in the mantle, drying it.
If the spa creation may cause most of it, then it has references more than the moon. Other giant side effects appear to other bodies, especially Quell and Mars. We may notice the paper that these giant effects play evolution of intermanes on planets.
Chang’e results are presented in four papers (1,, 2,, 3,, 4) published recently in the journal character.
