A groundbreaking new mission is set to revolutionize our understanding of solar storms and their impact on Earth. The Mesom (Moon-enabled Sun Occultation Mission) aims to create artificial solar eclipses in space, offering a unique opportunity to study the Sun's atmosphere in unprecedented detail.
Solar storms, caused by the collision of magnetic fields and electrically charged particles with Earth's magnetic field, can disrupt vital technologies, as evidenced by recent extreme solar storms. The current intense solar storm serves as a stark reminder of the need for improved forecasting and understanding of these events.
The Mesom mission, led by an international team of researchers, including experts from the Surrey Space Centre, proposes a novel approach. By utilizing the Moon as a natural occulting disk, it aims to recreate total solar eclipse conditions in space. This method allows for prolonged and high-quality measurements of the Sun's corona, down to the chromosphere, without the atmospheric distortions experienced on Earth.
The Moon's near-perfect spherical shape and lack of a thick atmosphere make it an ideal celestial body for this purpose. The Mesom mission, a mini-satellite project, will collect high-resolution data once a month, providing valuable insights into the Sun's inner corona. This is a significant advancement, as ground-based and space-based coronagraphs have limitations in capturing the deepest layers of the Sun's atmosphere.
The mission's feasibility study, funded by the UK Space Agency, has expanded into an international consortium. It is now being considered by the European Space Agency as a potential future mission, with a proposed launch in the 2030s. The Mesom mission offers a rare opportunity to study the Sun's atmosphere and improve our understanding of solar storms, which could have far-reaching benefits for technology and Earth's protection against Carrington-like events.
