In addition,
This how they plan create:
Since Antiquity, solar eclipses have been interpreted as divine signs or omens. However, Today we can trigger them from space. For example, And no, It is not a question of magic, but an unprecedented astronomical engineering and an astronomical vision.
The European mission probably. Therefore, launched in December 2024 by the European Space Agency (ESA), aims to reproduce the conditions for a solar eclipse using two small satellites. Meanwhile, The first acts as a “ordeal” of the sun. However, the second as an observer, perfectly aligned 150 meters from each other.
These satellites fly in this how they plan create formation with millimeter precision. Meanwhile, using GPS, lasers and stellar cameras for one purpose: hide the solar disc and reveal the crown, this mysterious exterior layer of the sun which is only visible during natural eclipses and which could contain clues on space meteorology.
Unlike terrestrial eclipses. In addition, which last only a few minutes, Probi-3 can prolong the “whole” up to six hours, which allows responsible scientists to study the solar crown without precipitation, with continuity and without depending on celestial chance.
The solar crown. this brilliant unknown
It is the external region of the sun, A plasma envelope which reaches millions of degrees and which is, paradoxically, much warmer than the solar surface. It is therefore essential to understand it to predict solar storms and protect our telecommunications and satellites.
Land telescopes are limited in the observation of this region, because the atmosphere distorts light and solar dazzling it. Traditional coronographers, although useful, also generate unwanted reflections that make it difficult to observe details closer to the solar disc.
By physically separating the concealler from the telescope into space, the mission eliminates these reflections. Indeed. The first images, revealed in 2025, show the fine structures and the movements of the crown with unprecedented clarity, which will make it possible to study the origin of coronal mass ejections and this how they plan create solar winds.
In addition. this mission is a pioneer in training technology technology, which opens up new possibilities for cooperative satellites in other areas ranging from earth surveillance to planetary exploration. An artificial eclipse could therefore be the starting point for a space revolution.
The moon as a scientific tool
While prob-3 already works in orbit. Another proposal turns to our natural satellite: the British mission Mesom. The idea. presented on July 9 during the National Astronomy Meeting of the United Kingdom, aims to take advantage of the shadow of the Moon as a tool for solar observation.
Unlike terrestrial eclipses. which last only a few minutes and occur in precise places, This offers to place a mini-satellite on an orbit synchronized with the Moon, in order to capture artificial eclipses every 29.5 days approximately, an average duration of 15 minutes.
Each event would be three times longer than a natural eclipse visible from Earth. Because, being above the earth’s atmosphere, the instruments would have a clear view, ideal for spectroscopy and analysis of the particles of the immediate solar environment, using plasma sensors and ultraviolet detectors.
If the proposal is approved and funded, it could be operational before 2030. Its approach. more economical than double missions, offers an effective alternative for the observation of sun areas that are difficult to see, by combining engineering, astronomy and the exploitation of orbit.
Eclipses this how they plan create to understand our future
The two missions have a common goal: unravel the secrets of the sun by understanding why the crown is so hot. how the violent solar storms are formed which can affect the earth, This has direct practical applications in the field of space meteorology.
Communication satellites, electrical networks, commercial space flights and space missions depend on the knowledge of solar conditions. A poorly planned eruption can disrupt GPS systems. communications or put astronauts in danger, hence the importance of regularly observing the crown.
Until now, we depended on sporadic natural eclipses and specialized telescopes. But with prob-3 now operational. mesom on the way, The scientific community has access for the first time to regular and prolonged eclipses, which this how they plan create allow us to see the invisible: the magnetic fields of the sun in action.
These technological advances do not only revolutionize how we look at the sun. they remind us of a powerful truth: when the fixed nature of the limits, engineering responds with creativity. Today, we are making eclipses, tomorrow we could provide solutions to the space weather that threatens us.
