Revolutionary Solar Observations Are Coming! A groundbreaking mission, named Proba-3, is set to transform the way we observe the Sun. It will achieve this by creating an artificial solar eclipse in space, a feat never before accomplished. This innovative endeavor focuses on studying the Sun’s corona, a complex and difficult-to-analyze region of its outer atmosphere.
The Proba-3 mission comprises two sophisticated satellites working in perfect synchrony: the Occulter Satellite (OSC) and the Coronagraph Satellite (CSC). The OSC is equipped with a 1.4-meter-wide occulting disc that effectively blocks sunlight, forming a narrow shadow approximately eight centimeters wide when positioned 150 meters away from its counterpart. Within this shadow, the CSC is located, which is fitted with a telescope featuring a 5-centimeter aperture.
To achieve their ambitious observational goals, the two satellites will maintain a meticulously precise formation, operating with millimetric accuracy. This level of precision allows them to create the ideal conditions for capturing high-quality data about the Sun’s corona, which has remained elusive to scientists for years.
The significance of this mission extends beyond mere observation; Proba-3 presents a unique opportunity to enhance our understanding of solar dynamics and their impact on space weather. This innovative approach is poised to yield unprecedented insights that could revolutionize solar research.
