The Indian Space Research Organisation (ISRO) has shared details of the first light of the Sun captured by the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) spectrometer onboard its Aditya-L1 spacecraft. HEL1OS, developed by the Space Astronomy Group of the U R Rao Satellite Centre, ISRO, Bengaluru, has successfully recorded the impulsive phase of solar flares during its first observation period from approximately October 29. This marks a significant milestone for the Aditya-L1 mission, which is dedicated to the comprehensive study of the Sun.
ISRO’s Aditya-L1 Successfully Captures First Light of Sun
HEL1OS is one of the seven scientific payloads onboard Aditya-L1. It is designed to study the Sun’s corona, the outermost layer of the Sun’s atmosphere, by observing its emission in soft X-rays. Soft X-rays are produced when highly energetic electrons interact with matter in the corona. By studying the spectral properties of soft X-rays, HEL1OS will be able to provide insights into the physical conditions and processes in the corona, such as the heating of the corona, the acceleration of energetic particles, and the occurrence of solar flares.
The successful capture of the first light of the Sun by HEL1OS is a testament to the capabilities of Aditya-L1 and its scientific payloads. With its strategic placement at the Lagrange point 1 (L1) of the Sun-Earth system, Aditya-L1 will be able to continuously observe the Sun without any occultation or eclipses. This will allow for a more comprehensive understanding of the Sun’s dynamics and its impact on Earth.
The Aditya-L1 mission is a major step forward for Indian space science. It will provide valuable insights into the Sun, which is the primary source of energy for Earth and has a profound impact on our planet’s climate and space weather. The mission is also expected to contribute to the development of new technologies for space exploration and satellite communication.
