The Aditya-L1 Mission is ISRO’s first dedicated mission to study the Sun. It is a spacecraft that will be placed in a halo orbit around the Lagrange point L1 between the Earth and the Sun, where it will study the solar atmosphere in unprecedented detail.
The primary scientific objectives of the Aditya-L1 Mission are to:
- Study the dynamics of the Sun’s chromosphere and corona.
- Investigate the heating mechanisms of the Sun’s corona.
- Understand the origins of coronal mass ejections (CMEs).
- Study the impact of solar activity on Earth’s space weather.
The Aditya-L1 spacecraft will carry seven scientific instruments, including:
- Visible Emission Line Coronagraph (VELC): This instrument will study the Sun’s corona in detail, including its temperature, density, and velocity.
- The Solar Ultraviolet Imager (SUVI): This instrument will image the Sun in ultraviolet light, which will allow scientists to study the solar atmosphere in more detail than is possible with visible light.
- Aditya-L1 Hard X-ray Imager (AHXI): This instrument will image the Sun in hard X-rays, which will allow scientists to study solar flares and other energetic phenomena.
- High Resolution Solar Physics Telescope (HRSPT): This instrument will provide high-resolution images of the Sun, which will allow scientists to study the fine structure of the solar atmosphere.
- Solar Magnetism Imaging Telescope (SMIT): This instrument will image the Sun in polarized light, which will allow scientists to study the Sun’s magnetic field.
- Plasma Analyzer for Solar Wind (PAS): This instrument will measure the composition and velocity of the solar wind.
- Particle Detector for Energetic Radiation (PEX): This instrument will detect energetic particles that are produced by solar flares and other energetic phenomena.
