It is a solar observatory mission launched by ISRO to the L1 Lagrange point using the Polar Satellite Launch Vehicle (PSLV) XL.
- Aim to study the layers of sun, solar wind and Coronal Mass Ejection, flares.
- The primary objective of Aditya-L1 is to gain a deeper understanding of the Sun’s behavior, including its radiation, heat, particle flow, and magnetic fields, and how they impact Earth.
Lagrange Points
- Lagrange points are special positions in space where the gravitational forces of two large orbiting bodies, such as the Sun and the Earth, balance each other out.
- Solar Wind: The solar wind is made of plasma (ionised atoms), a stream of energised, charged particles, primarily electrons and protons, flowing outward from the Sun at speeds as high as 900 km/s and at a temperature of 1 million°C.
- Solar Flares: Solar flares are magnetic storms that appear as very bright spots with a gaseous surface eruption.
- Coronal Mass Ejection (CME): A Coronal Mass Ejection (CME) is a massive burst of plasma and magnetic field released from the Sun’s outer atmosphere (the corona) into space.
