Solar Flares vs Satellites: Who will emerge victorious in this space battle?
In recent decades, the active development of outer space has led to a significant increase in the number of artificial satellites in Earth orbit. Companies seeking to provide global high-speed Internet coverage have become particularly active in this area, including Elon Musk's SpaceX Starlink project.
Today, in 2023, there are almost 9,000 active satellites in orbit, of which 4,755 belong to the Starlink project, which is 55% of the total number. This trend could lead to Kessler syndrome, a catastrophic chain reaction of satellite collisions that could make near — Earth space impassable for future space missions.
The essence of Kessler's syndrome is that at a certain critical density of satellites in orbit, the probability of collisions between them increases, which in turn leads to the formation of a cloud of space debris, increasing the risk of further collisions.
Particularly dangerous are space weather events, such as solar flares and coronal mass ejections, which can seriously damage the electronics of satellites, making them unmanageable. In this case, the probability of collisions increases dramatically.
Now the Sun is gradually approaching the peak of its 11-year activity cycle, which increases the risk of strong solar flares and coronal mass ejections. These phenomena can cause serious damage to satellite electronics, rendering them unable to control and increasing the risk of collisions.
However, there is a potential solution to this problem. A series of solar telescopes and observatories can monitor solar activity, providing up to three to four days to prepare for possible space storms. If a threat is detected, megaconstellations satellites can be moved to pre-planned "safe" orbits, minimizing the risk of collisions.
However, at the moment, the infrastructure of satellite megaconstellations, including Starlink, does not provide such a "safe mode". Therefore, the operation of these satellites continues to carry the risk of a space catastrophe in the event of serious space weather events.
Experts emphasize the need to take precautions now to avoid catastrophic consequences in the future and to ensure the safe development of outer space.
