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.
Scientific Objectives
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.
Payload
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.
