Recently, the China Meteorological Administration issued an unusual warning that extends beyond the Earth to hundreds of kilometers into space, affecting China's space station and the U.S. Starlink satellite program.
The protagonist of the early warning is "space weather", a relatively unfamiliar but far-reaching phenomenon. On December 1 and 2, strong geomagnetic storms are expected to occur, rooted in the Sun's upcoming 25th cycle.
Why does solar activity affect the Earth?How will it affect our daily lives, the orbital operation of the Chinese space station, and the Starlink satellites of the United States?
First of all, the sun is a huge "electromagnetic pulse**" through nuclear fusion, the sun emits a large amount of light and heat, and at the same time produces electromagnetic radiation. This radiation, especially at the peak of the Sun's activity, can create a strong electromagnetic shock that can have a profound impact on the Earth.
The direct consequences of geomagnetic storms include interference with radio signal transmission. For example, the signal between the mobile phone and the base station may be interfered with, affecting the efficiency of communication. Historically, solar activity has caused satellites to lose contact and even interfered with communications systems on the battlefield.
Secondly, intense solar activity can also affect the electrical system of modern society. Streams of fine particles can wreak havoc on delicate electronic devices, as exemplified by the 1989 North American blackout.
However, for the Chinese space station in space and the American Starlink satellites, the most serious threat may be the ** of the atmosphere. Increased solar activity expands the Earth's atmosphere by heating, increasing the air resistance of space stations and satellites in orbit. This means that China's space station may need to make orbit adjustments more frequently to avoid a runaway crash like the one in 1978 when the U.S. Skylab space station did.
The threat to the U.S. Starlink satellites could be even greater. Although these satellites have some maneuvering capabilities, their orbital positions may be severely affected by the influence of atmospheric expansion. In February, a sudden change in the atmosphere caused 40 Starlink satellites to crash. If there is a larger scale of solar activity in the future, Starlink satellites may be more at risk.
In addition, the intense electromagnetic radiation and particle streams brought by solar storms pose a deadly threat to satellites in space. Even though Starlink satellites are an asset to the United States, we still want to avoid this from happening, as the large amount of space junk will cause serious disruption to normal space activities.
This space weather warning is not only a reminder of the wireless communication and power system on Earth, but also a severe test of key assets in space. It reminds us that both life on Earth and exploration in space are intimately connected to the Sun, a member of this large, active solar system. We must always be prepared to meet the challenges of the sun to ensure the safety of our planet and space assets.

The intensification of solar activity, especially the occurrence of geomagnetic storms, has a direct impact on the electromagnetic environment on Earth. This effect can lead to communication disruptions, increased errors in the navigation system, and even a negative impact on the grid system. This is not only a technical issue, but can also have a significant impact on economic and social life, especially in a modern society that is highly dependent on electronic technology.
For satellites and space stations in low-Earth orbit, increased solar activity means they will be at greater risk. For example, China's space station needs to perform orbital maneuvers to avoid increased air resistance, while U.S. Starlink satellites may face more serious challenges because they may not have enough maneuvering capabilities to adapt to such changes. This not only poses a threat to the normal operation of these facilities, but could also affect the services on Earth that rely on these satellites.
More seriously, if the Starlink satellite fails due to a strong solar storm, it could leave a large amount of space junk in low-Earth orbit, which poses a long-term threat to future space activities. The problem of space junk is already the focus of international attention, and any incident that could add debris to orbit should be taken seriously.
This event highlights the importance of our study of solar activity and space weather forecasting. As humanity becomes more dependent on space, the monitoring and monitoring of solar activity will become increasingly important. This is not only a field of scientific research, but also a major issue related to economic stability and social well-being.

The sky is alarmed, the sun is crazy, and the geomagnetic riot is panicking. The empty station is urgent, Starlink is in danger, and the universe is stormy.
Light and heat are strong, electromagnetic disturbance, and science and technology are sad. Space hangs, star orbits shake, and the sky is changing.
The empty station must be urgent, and the storm is impermanent. Starlink Guard, it is difficult to protect itself, and thousands of them are afraid of death.
Electromagnetic fierce, the sun is fierce, and the sea of stars is windy. Space travel, difficult to be peaceful, celestial alarm bells.
