After the successful launch of China’s Chang’e 5 project on November 24, and now that Chang’e 5 Completes Lunar Drilling Sample, the outside world has become keenly interested in the second attempt to collect lunar resources in human history. Of course, not surprisingly, some “things” hiding in “subspace” are still struggling in secret, hoping to see failure.
Chang’e 5 Completes Lunar Drilling Sample
According to news from China’s state media “CCTV News” on the night of December 1, after nearly a week of flight, Chang’e 5 successfully completed its departure mission on the scheduled orbit. At 23:11 that night, the probe was successful. Landing at the predetermined target location. This also represents the third success of my country’s “soft landing on the moon”. According to the official introduction, in the next 48 hours, the probe will perform the mission of collecting the lunar soil environment as planned.
Contrary to what many netizens guessed before, the location where the Chang’e-5 probe landed on the moon, contrary to the previous Chang’e-4, landed on the front of the moon. The approximate location is 51.8′ west longitude and 43.1′ north latitude. At that time, the probe began to descend at a distance of about 15 kilometers from the surface of the moon, at a speed close to 1.7 kilometers per second. After several automatic adjustments to the landing attitude, the probe landed smoothly. In addition, because it was previously considered to carry the lunar soil back, the lander actually “carried” a larger “riser” to return to the lunar orbit later.
It should be noted that due to the full live broadcast method, it can be intuitively felt from the relevant news screen that the overall screen delay rate is not high, and the landing screen freeze is small. In the eyes of many people, this may only be a network problem, but in fact it is a manifestation of the strength of my country’s entire deep space measurement and control. Either it is to maximize the use of “channels” in the limited transmission signal; or it is that my country’s detection network can effectively reach the lunar surface. Regardless of which type, at least currently on a global scale, only China can reach the entire standard.
Of course, many people may use “Apollo Moon Landing” for comparison. But in fact, many of the American moon landing videos we see today are post-production based on the video at the time. They are not live broadcasts in my country, but are real-time images at the first time. Of course, this is also a development issue of communication technology. After all, after the 90s, “digital signal communication” began to appear in the world. Prior to this, it was all fuzzy signal technology, which is certainly not as good as “digital communication” in terms of communication delay and clarity. Therefore, the two are actually not comparable.
It is worth mentioning that before this, many people in the international public opinion expected this project to fail. And now the smooth landing of the Chang’e-5 probe also indicates that the entire project has been half-successful. This undoubtedly proves with facts that these people can’t recognize the reality, and they only dare to hide behind the screen and speak out. Now that Chang’e 5 Completes Lunar Drilling Sample!
At 4:53 on December 2, Beijing time, the lunar exploration project Chang’e-5 lander and ascender assembly completed the lunar drilling, sampling and packaging.
After the probe successfully landed on the lunar surface at 23:00 on December 1, it carried out relevant preparations such as the deployment of the solar wing and the unlocking of the mechanism. The automatic sampling task of the Chang’e-5 detector adopts the combination of surface drilling and multi-point sampling, and two “digging” modes of drilling tool drilling and mechanical arm surface sampling are designed.
