The landing journey of the Japanese lunar probe Slim can be described as tortuous and arduous. After a series of problems, Slim was eventually forced to shut down and built up after rebootingCommunications, but unfortunately went into hibernation. This sparked a lot of interest in people about slim with India's "month."Boat No. 3".Discussion of the similarities of the detectors. However, Slim is different from India's Chandrayaan-3, why exactly? Below I will give some explanations from my personal point of view.
Japan's exploration of the moon has had its ups and downs. Although Japan successfully conducted three lunar exploration missions and landed only on the third, they gave their mission a score of only 60, or just under half the success rate. Although the landing site was more than 50 meters away from the expected position, it was still within 100 meters of the landing range, which was considered a success. However, the problem of slim breakdowns has been continuous. As I mentioned earlier, Slim landed with his head on the ground, and as you can see from the state of the probe, the engines are all facing up. Although the Japanese official initially claimed that it was a "side landing", in practice there were problems in the process, including the engine nozzle falling off, etc., resulting in the landing process was not perfect. In addition, there are problems with solar panels. Despite the fact that Japan managed to shoot some ** from the moon, there is also an explanation for the problem of Slim before landing. Before landing, two ultra-small lunar rovers LEV-1 and LEV-2 have been successfully released. In addition, the Multi-Band Spectroscopic Camera (MBC) installed on the Slim can be pre-run and capture images before the power is turned off, so that's how these ** are generated.
Overall, SLIM's core mission is to validate precision landing technology and inform future lunar and planetary exploration missions. From this point of view, Slim's mission can be considered a success, and a multispectral observation of the rock image was obtained. However, it is important to point out that SLIM's success did not depend solely on its own strength, and India and the United States were indispensable for helping Japan. India provided images of India's Chandrayaan-2, and the United States provided landing support. Japan has shown its honesty by openly acknowledging these helps. However, compared with India's Chandrayaan-3, Japan's lunar exploration mission is indeed inferior to others. Why, then, is Japan inferior to India's lunar mission?
India's Chandrayaan-3Although some problems were encountered during the mission, the landing was not met with the same difficulties as in Japan. Moreover, India quickly released the lunar rover after landing and launched a mission for about 10 days. It's a bit short compared to the original 14 days, but what about Japan? Slim encountered a malfunction during the landing, in order to recoverCommunicationsand also had to actively close, as a resultCommunicationsIt lasted only two days before it went into hibernation. Tossing back and forth like this is really not as good as India. If there is a problem with the landing process, it will be likeIndia's Chandrayaan-3All the same, "frozen to death" on the moon. The possibility that the Japanese probe could be damaged by the cold of the moon became their concern. Of course, according to the Japan Aerospace Exploration Agency, they turned off the power to the probe by ground command, and if measures were taken during the landing, it would have been possible to wake the probe again. However, if there is a malfunction during the landing process, the probe may beIndia's Chandrayaan-3The same was "frozen to death". This means that the end of the probe may be regrettable.
It can be said that for Japan, they have more difficulties in the mission to the moon than India. This also reflects the difference in space power, with the United States having reservations about its support for Japan and India. If they are fully supported, they will not be able to spend even the "night" on the moon as they are now, and they will have a plan to deal with it. On the whole, Japan's mission to the moon is indeed inferiorIndia's Chandrayaan-3mission, at least in the course of the mission, there were no major problems like Japan.
There are many reasons why humans have explored the moon, but I will list two of the more direct ones. First, in terms of engineering goals, the moon landing can verify key technologies throughout the flight process and prove whether the vehicle is reliable. Secondly, inScienceTargets, such as the lunar soil collected by the Apollo missions and the installation of lunar geodemiological detectors and laser emitters, are importantScienceValue. So, the moon landing can achieve all sortsSciencegoals, which are the benefits of the moon landing.
The biggest goal, of course, is to look forward to the early realization of the exploitation of the lunar resources. The moon is very rich in resources, including a large amount of helium-3, and it is estimated that the simple acquisition of helium-3 can satisfy the earth for up to 10,000 yearsEnergyDemand. Therefore, if these resources can be accessed sooner, it will completely change the planetEnergypattern, solvedEnergyShortages, which is a very much anticipated goal.
To sum up, Japanslim detectorThe road to the moon is relativeIndia's Chandrayaan-3It's really more tortuous and difficult. This is partly due to technical problems, such as malfunctions such as engine nozzles falling off during landing. In addition, Japan's support for the lunar mission is not as good as India's full support from the United States. However, both the Japanese and Indian missions to the moon faced many challenges and difficulties. We look forward to more countries successfully landing on the moon and achieving the goal of human exploration in the future.
