China has succeeded again! The successful launch of the Einstein probe satellite marks another major achievement in space exploration by the mainland.
According to the report:
At 15:03 Beijing time on January 9, 2024, the mainland successfully launched the Einstein probe satellite using the Long March-2C carrier rocket at the Xichang Satellite Launch Center.
Therefore, the whole mission was a complete success, and many people have raised questions about the strength of China's Einstein probe satellite this time, so let's explain it below.
In fact, compared to other countries, China's Einstein probe satellite is far surpassed, this is not bragging, but the implementation of the situation, especially in India, which also launched this type of satellite in January 2023, although China is behind India, but the relative strength has a unique point.
There was also a US launch before India, so I will first use India's to compare and explain.
Indeed, in 2023, among the world's first space missions, India carried out the mission and successfully launched the "black hole" satellite, which India called the XPoSat satellite, which, like China's Einstein probe satellite, is an X-ray astronomical satellite.
India's X-ray astronomical satellite, the XPoSat satellite, whose main mission is to collect X-ray radiation emitted by black holes and other celestial bodies, carries two scientific instruments, costs nearly $30 million, and has an estimated lifespan of five years. Before it, NASA launched a similar mission in 2021 and made unprecedented discoveries, and the second country to carry out the mission was India.
Therefore, China successfully launched the Einstein probe satellite, which is the third in the world.
Of course, the Einstein probe satellite is a scientific satellite independently developed by China, and it is very versatile.
It is also crucial to reveal the peaceful "lurking" black holes at various scales as the main body of cosmic black holes, to detect and establish samples of various known and unknown X-ray transient sources and to establish their samples, and even to capture the electromagnetic counterpart of gravitational-wave burst sources for the next generation of gravitational-wave detectors.
To put it bluntly, they all belong to "black hole" satellites, but China's launch of the satellite has also been postponed many times, and it has been postponed twice, which may be a change brought about by the improvement of technology.
In 2017, Continental announced that the Einstein probe satellite would be launched around 2021.
But there was no launch around 2021, and in 2022, the mainland announced that it would launch at the end of 2023, but it was still not launched.
So, the competition with the United States was missed, and the competition with India, at least in terms of launch time, after India, the United States.
However, to tell you, this may be the mainland is making technological adjustments, so it is a little late, and this is not an intentional statement, because the fact itself is that China has created the technology on the Einstein probe satellite and achieved the technology that surpasses that of the United States and India, and neither country has the technology.
This is the world's first true wide-field X-ray focusing imaging telescope, and its observation range is 100 times or more than that of other X-ray focused imaging telescopes.
Moreover, it is also the first large-scale use of "lobster eye" micropore array focused imaging technology in the world, which can achieve a 10-fold increase in sensitivity and spatial resolution, and can accurately capture the more distant and faint high-energy temporary sources and fleeting unknown phenomena in the universe while monitoring a large field of view, and issue an early warning to guide other astronomical equipment based on the earth and earth to carry out follow-up observations.
In addition, multiple X-ray sources, including black holes and neutron stars, have also been detected, allowing multiple explorations to be carried out at a time.
In addition, the instrument also detects X-rays from quasars located 814 million light-years from Earth, that is, it can see through 814 million light-years at a glance, proving that it has the ability to detect fainter X-ray sources.
So, China has created a "space weapon" again, and I'm not bragging, am I? These technologies are realized by China. Previously, India and the United States did not have such capabilities.
Moreover, under the achievements of exploration, China will inevitably be able to create some historic achievements.
However, many people may have read it and will say such a sentence, which is what I hear the most every time I write about the aerospace field, and I will take this opportunity to explain that I don't feel that anything has anything to do with ordinary people, and I can only say here - astronomical significance is powerful, and it is still meaningful to understand the process of change in the universe.
At the same time, the research and realization of these projects themselves have the potential to promote the development of other industries in the mainland, so it does not mean that the implementation of a project is independent.
Including when the mainland built the space station, some people have always said that they didn't see anything to do with ordinary people, which is actually a "big mistake", when the mainland space station was developed, it also promoted the development of various industries, and at the same time, space experiments are also closely related to ordinary people, but I don't know much about it, so I just said it casually.
For example, if you study rice in space, do you think it has anything to do with ordinary people? This must be true, and you may be able to achieve greater yields through space research.
Therefore, any project is closely related to everyone, don't see that the targeted projects are different, there is no need to say so, if it is really everyone who says this, the World Astronomical Research Center will all "go out of business".
Therefore, it is expected that the mainland will make a breakthrough in this regard, bring practical astronomical knowledge, and see what surprises the changes in black holes will bring to everyone.
