Recently, everyone is racing against time to spend the May Day holiday, either trekking through mountains and rivers to travel or two light tea Ge You lie, for this long-awaited holiday, the body and soul must always have one on the road.
And just when everyone was idle on May Day, the news of Chang'e-6's launch received widespread attention as soon as it came.
On May 3, Chang'e-6 was successfully launched at the Wenchang Rocket Launch Site in Hainan Province, and soared into the sky under the carrier rocket of the Long March 5. As soon as the news spread, a group of netizens who traveled in the mountains and rivers shouted: The cow has arrived home.
From the launch of Chang'e-6, we can also see China's determination to explore the universe, and we have never stopped "marching" into space.
This time, the successful launch of Chang'e-6 also attracted much attention, and as soon as it was launched, countless people were concerned about its return date.
The official also released information about Chang'e-6, which said that it would take 53 days for Chang'e-6 to land on the moon and then return to Earth.
As soon as this news came out, it caused a wave of doubts, 40 years ago, the American astronaut Armstrong left the first footprints of mankind on the moon, thus beginning the road of human measurement of the universe.
Armstrong's Apollo 11 took only eight days to complete the dream.
And these two lunar probes, spanning nearly 40 years, but the difference is such a long time, as soon as the data comparison came out, it triggered countless discussions, does this mean that our skills are inferior to others?
In 1969, Apollo 11, which completed the first human lunar landing operation, was limited by the times at that time, and it was composed of three simple parts: the service module, the command module, and the lunar module.
After all, forty years ago, the scientific and technological means were still a little backward, and it was impossible to create a spacecraft as shocking as in the movie, even if the United States, which was leading in science and technology at that time, could still only build such a probe that could only last on the moon for eight days.
And it was such a simple and ugly lunar probe that left an indelible mark on the history of world astronautics, and Armstrong's small step marked a giant leap for mankind.
The United States also used these eight days to demonstrate its strong scientific and technological strength, and in this way, it won more voice in the international community.
Before the launch of Apollo 11, the United States and the former Soviet Union were very tight in the field of space, and since the United States secretly developed Apollo 11, astronauts have also brought back many precious specimens and impressions on the moon.
The United States has gained a firm foothold in the aerospace field with a flag planted on the moon, thus securing the position of the aerospace boss.
The structure of Apollo 11 is fairly simple, and the lunar module can be roughly divided into two parts, namely the upper and lower stages, as the name suggests, one for ascent to lunar orbit and one for landing on the moon.
At that time, the lunar module and the service module were very similar to the construction principle of today's launch vehicles, both had sufficient reserves of raw materials, and when the fuel ran out, they would be abandoned in space.
Moreover, the main purpose of the service module of Apollo 11 is only to control the overall shape of the spacecraft, so as to ensure the smooth connection between the spacecraft and the orbit, and make sufficient preparations for landing on the moon and being on the moon for a certain period of time.
The indicator module is the control center of the entire spacecraft, and it is also the place where the astronauts will rest and work. The cabin is not only equipped with some sophisticated instruments, but also reserves some daily necessities.
However, due to the small size of the Apollo 11 cabin, it could not store too many daily necessities, and the precious fuel could not support the spacecraft to carry heavy items. As a result, astronauts can only survive on the moon for a few days under limited living conditions.
In short, Apollo 11 cannot support astronauts to live on the moon for a long time, both in terms of overall structure and material conditions, and eight days may be its limit.
In the end, Apollo 11 left the service module in space forever after running out of fuel, and finally landed at sea, ending the first human journey to the moon.
And this trip to the moon, the American astronauts brought back precious specimens and some images on the moon, and this has completed the mission, after all, the ultimate purpose of the United States to develop Apollo 11 is not to do any research, but to deter the former Soviet Union, which lives in space and is equal to its own strength.
The mission of Apollo 11 on this lunar landing trip is to surpass the former Soviet Union during the Cold War, regain the initiative in aerospace, and demonstrate its strong scientific and technological strength to the world. And from the moment several astronauts stepped out of the capsule, the mission was completed.
Back to the present, China has also shown strong scientific and technological strength in the field of aerospace, and the successful launch of Chang'e-6 once again confirms the mainland's strong ambition and outstanding capabilities in the field of aerospace.
Chang'e-6 is a behemoth weighing 8.2 tons compared to Apollo 11, which has a simple structure. Its structure is also very complex, of course, it also undertakes more research tasks, and its successful launch carries countless painstaking efforts and ardent expectations of scientific researchers.
And in addition to the large Chang'e-6 probe, the Long March 5 carrier rocket will also drop four small probes on the moon. And why does it take 53 days for Chang'e-6 to go back and forth?
It is precisely because it has undertaken many scientific research tasks that the main project of this lunar landing not only includes the technology of take-off and ascent on the far side of the moon, but also the scientific research technology such as intelligent sampling on the far side of the moon.
Therefore, Chang'e-6 needs to land at a designated location on the far side of the moon for exploration, start from a new exploration point to carry out new research from a new angle, and look forward to ushering in a new breakthrough in the field of aerospace.
The launch ceremony of Chang'e-6 was particularly grand, and on this May Day, several foreign friends came to Hainan to witness this great moment.
From the launch ceremony of Chang'e-6, we can see the importance that the mainland astronauts attach to this lunar landing operation, and this lunar landing trip will provide the mainland with very important scientific research value, which will play a certain role in promoting the long-term development of the mainland's aerospace field.
The reason why this flight lasted 53 days is naturally inseparable from its important mission, and the place where it will land and collect is the place that has been hit by meteorites the most in the entire solar system, and this basin is not only the largest meteorite impact crater on the surface of the moon, but also the oldest known basin on the moon.
This site will help us understand the more ancient side of the moon and will give us a better understanding of this cold planet in the heights.
The 53-day lunar landing operation will also be divided into 11 flight phases, and through these 11 stages, the sampling of the back of the moon will be gradually completed. It is precisely because this trip to the moon is the first time that mankind has completed sampling on the far side of the moon, which is of epoch-making and unique significance.
There is no doubt that exploring uncharted territory requires a longer preparation time. This has nothing to do with what kind of skills are inferior, and the two detectors only play different roles in different aspects.
It is ironic to confuse the Apollo 11 40 years ago with the recently launched Chang'e-6, and I wonder why the lunar probes spanning 40 years are being compared together.
Apollo 11 spent only eight days on the moon and American astronauts only walked on the moon for two hours, but these eight days were not only the first human journey to the moon, but also marked the victory of the United States in the space race.
In addition, the astronauts also brought many precious specimens back to Earth, which provided a certain direction and reference for the later space research of the United States.
The successful launch of Chang'e-6 also marks the beginning of the human sampling project on the back of the moon, which is also a new scientific research breakthrough.
