Raindrops on me. Almost everyone knows the beginning of this song, while there is a much less romantic “rush” that has to do with space. The satellites in orbit are located at many miles away from the surface of our planet, yet problems begin to arise when their period of activity ends.
The orbit of these technologies continues in most cases, but there are others that end up plummet in a dangerous way. Precisely in recent months, those that fall into the atmosphere have increased, a decidedly high number compared to normal. It is therefore legitimate to ask what is happening.
In addition to point in space where they punctually end up on tilt, satellites have to contend with much more intense solar activity than usual. Wanting to be even more precise, the “fault” would be the wind of our star that literally drags the devices up to the final “rain”. According to what experts have pointed out, the solar cycle has reached its maximum level and this is no small detail as regards the fate of the satellites. Space agencies are struggling with the loss of one tool after another, SpaceX primarily. Elon Musk’s “creature” recorded the fall of 40 satellites, precisely after a massive solar storm.
The sibylline prophecy
The abrupt return to the atmosphere has facilitated the destruction of the satellites, consequently no technology can be said to be truly safe. To make it even more alarming, a real prophecy is thinking about it. According to Anja Strommeone of the main minds of ESA (European Space Agency), the satellites that orbit a 400 kilometers of altitude they will have problems, as will the smaller technologies that have been rolled out over the past decade. It is not a question of mere pessimism.
The behavior of the Sun
Stromme pointed out that satellites that could be part of a dangerous rain in space do not have the right propulsion systems, which is why they are destined to return to the atmosphere earlier than expected. A small hope that the prophecy does not come true is all in the behavior of the Sun, of which the Earth has just reached the closest point. Every 11 years our star’s magnetic field reverses, causing storms that damage the satellites, but then promptly returns to its original position. In the 2019among other things, a solar cycle has begun which is about to reach an absolute maximum.
This last phase is foreseen for 2025, therefore it will not be necessary to wait too long to hope that the rain of technologies is not excessive. When in doubt Stromme and his colleagues have prudently decided to raise the orbit of some satellites, which were in low orbit (45 kilometers), but other adjustments should take place. before the end of the year. The goal is to make space missions safer, especially those started a long time ago that have to deal with the “whims” of the Sun. The future is undoubtedly uncertain, but it cannot be said that nothing is being done. to remedy the problem.
