For as long as humans can remember, they have always had a very fond imagination of space. Especially in the case of not being able to explore the space environment, people prefer to believe that it is the place where the heavenly gods live. As time goes by and technology advances, the concept of "space" becomes clearer and clearer in the minds of humans. More importantly, as more and more space probes are launched into space, many of the speculations once made can finally be confirmed one by one.
What many people don't realize, however, is that science is not exactly as rosy as it seems. In this path of scientific research, pay and gain at the same time, there is a high risk of other negative effects. In today's orbit around the Earth, for example, many artificial satellites, their successful entry into space, there are often hundreds of failed products.
As many people know, the development and study of the modern space sector generally begins with the U.S.-Soviet Cold War after the 1940s. When the Truman Doctrine was introduced, both the United States and the Soviet Union tacitly chose to compete with each other in avoiding direct armed conflict, thereby demonstrating their national strength. The space field, naturally, became the most appropriate "battlefield".
But in fact, as early as 1883, the world's father of astronautics Tsiolkovsky had put forward a great idea of using rockets to launch spacecraft, and even published this idea in the form of a paper. In a sense, Tsiolkovsky's idea is very similar to our famous Chinese space explorer Wan Hu during the Ming Dynasty, the difference between the two only lies in the difference between theory and actual experiment.
That is why space would have been an important area of human exploration even without the Cold War background of that era. Today, after decades of development, mankind has made many astounding achievements in the field of space. Space probes, artificial earth satellites and space stations, etc., mankind has finally been able to use this series of scientific achievements to better understand the universe.
Space probes and space stations aside, the former have been moving forward with the goal of exploring the depths of the universe since their launch, and do not even stay in extra-terrestrial orbit. And the latter in this day and age, only the United States and Russia and other six Western countries jointly established the International Space Station and China's "Tiangong" in steady operation, which may cause the impression of extraterrestrial space orbit can be completely negligible.
In this case, satellites are really relevant to our daily lives. To give a simple example, communication technology and navigation technology, which we are used to today, have actually become a reality with the help of satellites. If we lose the guidance of satellites, the way of life of human beings will certainly be changed.
But few people have thought about what would happen if a satellite suddenly lost contact with the ground after it was successfully launched and lifted off, and what that would mean. More importantly, will the satellite have a chance to return to the control of mankind in the following time?
In fact, when a satellite successfully lifted off but suddenly lost contact with the ground, the satellite is actually completely reduced to a "space wanderer". If good luck, these "strays" will not pose a threat to other human space probes and satellites, after all, the vastness of outer space, definitely far more than the surface. But if bad luck, then an extremely small piece of debris are likely to trigger a huge disaster.
As early as 1965, the United States had launched a communications satellite called LES-1, which in Chinese was called Lincoln Experiment Satellite One. In terms of U.S. expectations for this satellite, LES-1 brought together the most sophisticated technology in the United States and even the world at that time, and was expected to be able to work properly in space for about two years.
But what American scientists did not expect was that soon after the launch of LES-1, the entire satellite completely lost contact with the ground. What is even more desperate is that people do not even know where the satellite actually went due to the limitations of society's technological development. It was like a kite with a broken string, completely out of the hands of mankind.
In fact, in terms of design, with the American satellite technology at the time, such a mistake should not have occurred. Even though the satellite technology was relatively primitive, scientists were still using the methods belonging to that era to solve the relevant problems. Although the method is slightly complicated, but can never be classified as a mistake above.
To give a simple example, modern satellites generally look more simple and atmospheric, in the vastness of space like a genie to help humans observe and monitor the changes of the Earth. The LES-1, launched by the United States, has nothing to do with the word aesthetics. But if from a technical point of view, similar to the sledgehammer as plain and heavy LES-1, in fact, is precisely to facilitate the installation of various technical equipment.
What scientists did not expect, however, was a series of unexpected situations after LES-1 was launched into space. Not only in the positioning of the rocket connection route selection error, resulting in LES-1 does not have sufficient power to enter the intended orbit, but also due to the momentum wheel stopped working, so that the entire satellite in a tumbling state in space. Just imagine this image a little bit to know how headache the U.S. scientists really were at that time.
After the accident, U.S. scientists made several attempts to reconnect with the LES-1 satellite, but unfortunately, no matter what methods were used, LES-1 would not make any reply. In desperation, U.S. scientists could only take the initiative to declare the failure of the LES-1 launch, and in the following time, will not provide any help for U.S. communications technology.
However, events in the field of science often like to surprise people unawares. When everyone had given up, or even long forgotten the existence of the LES-1 satellite, it came back into the human view in its own way.
Lost and Found Satellite
On December 18, 2012, an astronomy enthusiast named Fils Williams submitted a report to the British Radio Society. In this report, Williams recorded his collection of a certain extraterrestrial signal. In his opinion, this signal with a frequency of 237 MHZ and a frequency band of 4 seconds once is completely different from the previous related infinite electrical signals. It would naturally be great if the British Radio Society could provide an answer to this.
By the time the news of Williams collecting strange signals in early 2013, it received more and more attention. Many people even speculated whether this could be a signal sent by alien beings or alien spacecraft, and use it to communicate and exchange with us humans. After all, in the inherent impression of many people, alien technological civilization is already stronger than the Earth's technological civilization, to be able to receive "alien signals", is already a very impressive achievement.
But in fact, after the final analysis of the British Radio Society, it turned out that the signal was from the LES-1 satellite, which had been out of contact with humans for 48 years, and the so-called aliens did not have much to do with it. After hearing this news, many curiosity seekers are very dissatisfied. Unfortunately, in the face of the established facts, dissatisfaction will not change any results.
And just as people are lamenting over the lost satellite re-transmitting signals to Earth, scientists are instead not happy at all. How exactly did the satellite regain its ability to transmit signals after 48 years of disappearance? More importantly, the satellite that has been defined by scientists as unusable is still able to transmit signals that are acceptable to humans, which is definitely not a good sign.
Signal Sources and Effects
To better explain the re-emergence of satellites that have been "dead" for nearly half a century, scientists have come up with a number of different conjectures, one of which has the most credibility, and another that has more willing believers.
The first is the reason for the influence of the radiation belt. 48 years ago, when the LES-1 satellite was launched into space, it actually ended up deviating on a trajectory near the Van Allen radiation belt region. And this radiation belt, referring to the near-Earth space, surrounded by the Earth's high-energy particle radiation belt. Compared to other heights of space, the Van Allen radiation belt has a lot more high-energy particles.
Not only that, in the Van Allen radiation belt, but also by the inner and outer layers, when the radiation belt of high-energy particles into the human occurrence of space probes and satellites after, will cause a certain degree of damage to human technological products. It's a pity that even now, scientists still haven't found a good solution, and can only let various vehicles get out of this area at a very fast speed.
From a scientific point of view, there is a great possibility that the LES-1 satellite, after reaching the Van Allen radiation belt and losing contact with humans, will move in a circular motion in the Van Allen radiation belt. In such a case, it will naturally be affected and impacted by high-energy particles all year round. When the constant impact of high-energy particles is paired with the continuous tumbling motion of LES-1, there is a possibility that the signal will be accepted by humans again.
The second is the reason why aliens control the emission of signals, scientists' explanation is always the constant pursuit of the truth, but for part of the public, in the face of incomprehensible things, it is easier to make people feel satisfied with the explanation instead of some until the reason. It's like in the field of space research, many problems are if added the presence of aliens, naturally will be more attractive.
The same goes for the signal problem of the LES-1 satellite. In many people's opinion, even if scientists believe that it has nothing much to do with aliens, how can alien technological civilization be so easily understood by humans? Scientists are unable to correct and refute this self-deceiving view. After all, there are so many satellites in extraterrestrial space, so why would aliens choose a satellite that has been obsolete for 48 years to deliver messages to humans?
In fact, whatever the reason for sending the signal is, it is really nothing more than a research topic. LES-1 is still in space after 48 years, which means that all the satellites launched before it are also in the same situation. In such a situation, the future of mankind in the choice of satellite launch route above, will certainly be more and more restricted.
What's more, when some threats in his air after the shattering, the formation of debris will also have a great impact on the space environment. You know that the speed in space is by no means the speed of the surface can be compared, even if it is only the size of an ordinary bullet fragments, in the collision to the artificial satellite, it is likely to cause a fatal threat. What's more, even if technology has developed to the present day height, we still have no way to deal with the garbage in space, we can only wait for them to naturally continue to drift on.
There is no doubt about the importance of space development for mankind. Especially since satellites are providing more and more help to human daily life, people need to develop more efficient satellites or even system satellite constellations to sustain development.
But suppose one day in the future, a certain space debris will suddenly intrude into the original satellite orbit, how can mankind solve this problem? For this reason, we should all understand that even in the "empty" space, we must adhere to the concept of sustainability.
