Voyager 1 runs out of battery after 4 years, this time it's free

Where is Voyager 1, the first human-made satellite? As of now, it is at a distance of about 22 billion kilometers from the sun. It has been 44 years since its launch. Relative to the speed of the earth, its speed is 17KM/S. Is this fast? For us living on the earth, this speed has exceeded the limit. The speed of sound propagation in the air is 340M/S, and the speed of Voyager 1 per second is 50 times the speed of sound, which is comparable to the diameter of the solar system. , which is about the same speed as a tortoise. And after 4 years, its battery will run out, and it will be free since then, and we will no longer get the data it sends out. The battery of Voyager 1 is a nuclear battery, which is provided by the decay of the radioisotope "plutonium" to provide electricity. Because it is not affected by the environment and temperature, "plutonium" has continued to provide Voyager 1 with electricity for 48 years. , to ensure that it has been feeding back various data to the earth during this period, so that we can remotely control it and observe it. The mission of Voyager 1 is to explore whether there is extraterrestrial life in outer space. It is equipped with 55 Earth languages ​​and a 90-minute music collection, as well as various human habits, structures, current technology, etc. At present, it has not flown out of the solar system. In the solar system, there are no other organic life forms that we have observed except our earth, but what if it flew out of the solar system? This is unknown. After all, the solar system is just an ordinary star of hundreds of billions of galaxies in the Milky Way, and it is really very small. The future of Voyager 1 is still to continue to fly. The next stop is that it will reach the galaxy in the constellation Ophiuchus in 40,000 years, and will pass through Proxima Centauri in 73,600 years. The premise of all this is that it has not encountered any accidents. After all, although space is vast, there are many meteorites and asteroids. As long as you touch or wipe it casually, the mission of Voyager 1 will inevitably end. Of course, all of this may not happen. Now its position is close to the edge of the solar system, that is, it is about to reach the interstellar space. It should be vast and quiet here! Voyager 1 is free. From its launch in 1977 to the present, 44 years have passed. This artificial satellite stepped into the sea of ​​stars full of fatigue and scars. There is no turning back. The hope of mankind and the pursuit of the exploration of the distant starry sky are gone. It is hard to imagine what its future will look like. We only hope that it can fly farther and fly faster to explore the mysteries of the universe that we cannot discover at present. Whenever I look up at the starry sky, I silently think in my heart that in the depths of the distant universe, our artificial satellites are still flying and exploring. Maybe this is hope. Although it is lonely, it is also free. Although the universe is mysterious , but there will be a day when it will be conquered.
