After a 46-year absence, a satellite is beamed back to Earth, and people are not happy.

In the 21st century, the launch of the satellite is not a new thing, for our star sea, from the use of science and technology to explore the universe, mankind has launched more than 4000 detectors, satellites and other spacecraft.

But due to a variety of reasons, some spacecraft in the launch or operation stage will appear all kinds of problems, resulting in the loss of contact, and some spacecraft successfully completed the mission will remain in space because of the recovery technology problems, and finally lost contact with the Earth.

After a 46-year absence, a satellite is beamed back to Earth, and people are not happy

A satellite sent a signal back to Earth 46 years after it lost contact with the planet. The sudden contact of an "old friend" satellite should make us happy for a while, but it did not. Is this satellite being manipulated by an alien civilization?

Satellite that's been out of contact for 46 years.

In 2013, an amateur astronomer observing space through a radio telescope picked up a faint 273 megahertz signal that appeared only two dozen times, but with remarkable regularity, at four-second intervals.

Remember that signals from the universe are generally irregular, and only humans are capable of emitting such regular signals. If this were the case, it would raise some terrifying questions, such as the source of the signal, could it be from an alien civilization?

When the astronomy enthusiast reported the signal, it caused a stir in the astronomy community, and the local space agency explained that the signal was not from an alien civilization, but was sent by a satellite called LES-1.

LES - 1 satellite launched by NASA in 1965, but due to technical problems at that time, when the satellite launch but can only stay in the plan outside of the orbit, and the center deviation, plus momentum wheel not normal work, lead to the satellite had to swirling around the earth, there is no way to send any useful information to the earth.

More importantly, LES - 1 satellite in orbit is just located in high-energy particle radiation belts, so subjected to large Numbers of charged particle bombardment, leading to the solar cells from being destroyed by the very serious, and the satellite can't recovery, so the United States would be forced to give up the satellite, in 1967, it finally lost the signal.

The worst fear is sudden contact from a missing satellite.

When NASA's explanation came out, many people didn't buy it, and there were plenty of arguments for it. For example, the technology was not advanced at that time, and the battery was carried. Normally, the life should be ten years. At that time, the environment was that the solar panel had been damaged and had been working for two years.

Even appeared a conspiracy theory, said that the satellite is not at a predetermined orbit, 46 years running already hit the space junk damaged, on the off chance that survive now again in a short signal, is due to the alien civilization at that time took the satellite, it is because of wrong operation makes signal leakage, just as it is received by the amateur astronomers.

For follow-up questions, faa and explanation are given, is due to the design of the power system has self-protection function, when the disconnection with the ground will enter a dormant state itself, and in the process of operation and all kinds of coincidence, that made the reactivation of the power system to send signals, then because of lost the signal.

But whatever the truth of the case, there are some real horrors lurking behind it. According to incomplete statistics, since the beginning of our entry into space, mankind has launched more than 4,000 satellites into space, these satellites are life, but according to the current technology, it is very difficult to recover a job.

As a result, abandoned satellites are forced to remain in space as space junk. Today, due to a variety of reasons abandoned satellites should have reached about 3000, when they become space junk, will lead to various problems, such as hindering astronomical observation, threatening the orbit of artificial satellites, squeezing space resources, become the biggest obstacle to human exploration of the universe.

In addition, with the continuous development of science and technology, people will rely more and more on satellites in the future. More and newer satellites will be launched into space at that time, so the space junk in orbit will pose a great threat to the satellites in service.

Therefore, the appearance of this signal is actually like a disaster, reminding us that it is urgent to deal with space junk. But at present, we are still studying the treatment of space junk, looking forward to more and better ways to deal with space junk in the future.
