The Aditya-L1 mission is a space-based observatory that will study the Sun from a vantage point in the Sun-Earth L1 Lagrange point. The L1 Lagrange point is a point in space that is located directly between the Sun and Earth, and it is about 1.5 million kilometers from Earth.
The Aditya-L1 mission is expected to launch on September 2, 2023, and it will carry seven scientific payloads. These payloads will be used to study the following aspects of the Sun:
- The solar corona and its heating mechanism
- Coronal mass ejections (CMEs) and their impact on Earth’s space weather
- The solar wind and its acceleration
- The solar magnetic field
- The solar atmosphere
- The solar interior
The Aditya-L1 mission is expected to provide valuable insights into the Sun and its impact on Earth. This information could be used to improve our understanding of space weather and its potential impacts on our planet.
Here is a brief overview of the seven scientific payloads that will be carried by the Aditya-L1 mission:
- VELC (Visible Emission Line Coronagraph): This payload will be used to image the solar corona in visible light.
- SSL (Spectral Line Imager): This payload will be used to image the solar corona in spectral lines.
- HMI (Helioseismology and Magnetic Imager): This payload will be used to study the solar interior and magnetic field.
- EPD (EUV Photometer): This payload will be used to measure the extreme ultraviolet (EUV) radiation from the Sun.
- SPP (Solar Particle Analyzer): This payload will be used to study the solar wind and its particles.
- MAG (Magnetic Field Investigation): This payload will be used to measure the magnetic field of the Sun.
- EDI (Energetic Particles Detector): This payload will be used to study energetic particles from the Sun.
The Aditya-L1 mission is a major undertaking for the Indian Space Research Organisation (ISRO). It is the first Indian mission dedicated to studying the Sun, and it is expected to make significant contributions to our understanding of our star.
