A space probe that passed through the boundary of the solar system and flew out of the solar system may be an important breakthrough in human exploration of the solar system and a major event in the anthropological community, but in fact, in the history of human exploration, a space probe named "Voyager 1" has already set off in 1977 and has been traveling in space for 45 years.
This space probe is named Voyager 1, and its goal is to fly out of the solar system and explore the boundaries of the solar system.
But unexpectedly, after 45 years of hard work, I still couldn't fly out of the scope of the solar system, so where is the boundary of the solar system, and how far is it from the boundary of the solar system?
1. Voyager 1.
In 1977, NASA successfully launched two space probes, Voyager 1 and Voyager 2, after the spacecraft Voyager 1 and Voyager 2 launched in the same year.
The main mission of these two space probes is to explore the outer space of the solar system and uncover more mysteries of the solar system for mankind through exploration and observation.
Regarding the specific tasks and plans of these two space probes, in fact, there were very detailed plans at the beginning of their birth, and after launch, they will also gradually fly to outer space according to the established plan and trajectory.
After being boosted by the gravitational pull of the wedge and Jupiter, the two space probes will extend outward, and in the long future, they will gradually fly towards the boundaries of the solar system.
"Voyager 1" and "Voyager 2" are the first generation of solar system probes developed by the United States, while "Voyager 1" and "Voyager 2" are considered to be the second generation of solar system probes, and the performance and function of their probes have also been greatly improved compared with the first generation of probes.
After their launch in 1977, Voyager 1 and Voyager 2, after exploring and photographing Jupiter, also explored and photographed planets such as Saturn as they continued to extend into outer space, and also revealed a lot of information about Pluto.
In 2012, Voyager 1 finally escaped the gravitational range of the solar system and officially entered interstellar space, which is also the first space probe in human history to enter interstellar space.
When Voyager 1 officially entered interstellar space, NASA announced this important news to the world, and people were excited about it, believing that this news would have great significance for human exploration of the solar system and outer space.
NASA also believes that Voyager 1 is an important breakthrough for human society, which is also considered a new milestone in human space exploration.
After Voyager 1 enters interstellar space, it will continue to fly and extend into outer space to explore interstellar space and reveal more information about interstellar space, which will also bring new ideas and perspectives to human space exploration.
However, just after Voyager 1 entered interstellar space, NASA announced another important news, that is, Voyager 1 is only less than 0.002 light-years away from the solar system, and it is still far from the boundary of the solar system.
This also confuses many people, according to NASA's previous explanation, Voyager 1's entry into interstellar space represents the boundary of the solar system, isn't this the case?
2. The boundaries of the solar system.
So, where are the boundaries of the solar system?
It is often said that the boundary of the solar system is actually the gravitational range of the sun, and this range is also known as the "sunspot spoke".
In this range, the gravitational pull of the sun is very strong, and the solar wind moving at high speed will be affected by the gravitational pull of the sun, and the speed will gradually slow down until it stagnates, and then they will be attracted by the gravitational pull of the sun and move towards the sun again.
Outside of this range, it is the boundary of the solar system, and it is also the boundary from which the space probe "Voyager 1" will fly.
However, even so, the scope of the boundaries of the solar system is not too clear, which leads to the fact that there is no clear standard for the definition of the boundaries of the solar system.
Among the many space probes, astronauts often use an energy called "sunspot convergence energy" as the boundary of the solar system.
This energy is actually a relatively weak solar wind, and it is this energy that can help space probes escape the gravitational range of the sun and enter interstellar space.
In the process of extending space probes to outer space, this energy will also be affected by some external factors such as solar wind, so their movement will become more complicated, and their number is not very large.
However, this energy has also brought a lot of help to human beings to explore the boundaries of the solar system.
However, the source of this energy is the subject of many scholars' speculation and research.
Among them, a more widespread speculation is that this energy is a kind of lower solar wind, which is blocked by some waves and shock waves in outer space, etc., within the boundaries of the solar system.
These waves and shock waves may come from collisions and interactions between stars.
In 2006, the International Astronomical Union declared that Pluto, no longer the ninth largest planet in the solar system, but a dwarf planet.
Although the controversy over Pluto's status has slowly subsided, it has brought many difficulties to astronomical research.
Pluto is the last planet in the solar system to be detected by humans, but because it is very far away from the sun, there is relatively little information about Pluto.
In 2015, NASA's New Horizons probe traveled to Pluto for exploration and photography, which was also the first close probe of Pluto in human history.
In the process of exploration and photographing by the New Horizons probe, people's information about Pluto has gradually increased, and after the New Horizons probe completed its mission and left Pluto, the New Horizons probe was also proposed to continue to another "asteroid".
However, this proposal has also sparked heated discussions among many people, because in people's perception, the New Horizons probe is only a one-time space probe in the solar system, and it can only detect and photograph Pluto once.
However, there is a reason for this proposal, that is, there are still many unknowns about the boundaries of the solar system, so a space probe with the ability to continue to the boundaries has become of great importance.
3. Voyager No. 1, in vain.
The flight paths of Voyager 1 and Voyager 2 were finally determined after comprehensive consideration and planning according to the launch capability and trajectory of the rocket, as well as the payload of the space probe.
At the same time, Voyager 1 and Voyager 2 also carried a "golden record", which recorded a lot of information and music about the earth, which was also considered by NASA to be a "business card of mankind".
They are designed to be a very durable medium in order to one day in the future, to be discovered by the creatures of extraterrestrial civilizations, so that they can come into contact with the creatures on Earth, which will also leave some traces of humanity if human civilization is extinct.
As the first space probe to enter interstellar space, Voyager 1 did not fly out of the solar system, but its exploration achievements are also very huge.
In the process of probing through Jupiter, Voyager 1 also revealed some information about Jupiter's atmosphere and moons, which played a very important role in the formation and evolution of the solar system for scientists on Earth.
When passing through Saturn, Voyager 1 also took many photos of Saturn and revealed some information about Saturn, which also provided important information for scientists to study Saturn.
In 2018, NASA released a report showing that Voyager 2 is flying out of the solar system at a speed of 15 kilometers per year, and Voyager 2 is closer to the boundary of the solar system than Voyager 1.
However, even if this is the case, Voyager 2 will still need about 20,000 years to get to the border of the solar system.
Voyager 1, compared with Voyager 2, is slightly farther away from the border of the solar system, so it will take about 40,000 years for Voyager 1 to reach the boundary of the solar system.
However, Voyager 1 and Voyager 2 cannot fly in space for 40,000 years, and during the flight, the space probes will be affected by some external factors, and eventually lose contact or fall.
Voyager 1, which was launched as early as 1977, has been flying in space for 45 years, and may lose contact with the Earth in the next 3 to 5 years, which also means that Voyager 1 may eventually disappear in the universe, and humans will no longer receive its messages.
However, this does not affect the importance of Voyager 1 and Voyager 2, their flight paths and exploration achievements are of great significance to human exploration of the solar system and outer space.
In the future, human exploration of the boundaries of the solar system will continue, and people will not only learn from the flight path and exploration achievements of the Voyager probe, but also design more advanced space probes to explore the boundaries of the solar system and interstellar space.
However, this is not without its challenges, the boundaries of the solar system are a large range, and the environment in outer space is also very complex, which requires more advanced technology and equipment to achieve.
epilogue
Mankind's exploration of the boundaries of the solar system is not only a technical challenge, but also involves ethical and life considerations, and how to protect human life and health during long-term flights will be an important issue.
In the process of exploring the boundaries of the solar system in the future, scientists may also discover some unexpected phenomena or laws, which will bring new breakthroughs and understandings to the fields of astronomy and cosmology.
At the same time, it will also promote the development of human civilization to a higher level.
