The full details of the Aditya L1 mission :
Aditya L1 is the first solar mission of the Indian Space Research Organisation (ISRO). It is a space-based observatory that will be placed in a halo orbit around the Sun-Earth Lagrange Point 1 (L1), which is about 1.5 million kilometers from Earth. The mission is scheduled to launch in September 2023.
The Aditya L1 mission has four main objectives:
- To study the solar corona, the Sun's outermost layer.
- To understand the physics of solar wind acceleration.
- To study the coupling between the solar atmosphere and the solar wind.
- To investigate the initiation of coronal mass ejections (CMEs), which are large expulsions of plasma and magnetic field from the Sun.
The Aditya L1 spacecraft is equipped with seven payloads to achieve these objectives. These payloads include:
- A Visible Line Emission Coronagraph (VLEC) to image the solar corona.
- A High-Resolution Coronal Imager (HiCRI) to image the solar corona in high resolution.
- A Solar Wind Composition Spectrometer (SWICS) to measure the composition of the solar wind.
- A Solar Wind Electron Proton Alpha Monitor (SWEPAM) to measure the energy and distribution of electrons, protons, and alpha particles in the solar wind.
- A Magnetometer (MAG) to measure the magnetic field in the solar wind.
- A Solar Particle Irradiance Monitor (SPIM) to measure the irradiance of solar particles.
- A Radio and Plasma Wave Investigation (RPW) to study radio emissions and plasma waves in the solar wind.
The Aditya L1 mission is a major milestone in India's space program. It will provide valuable insights into the Sun and its influence on the Earth's space environment. The data from the mission will be used to improve our understanding of solar storms and other space weather events, which can have a significant impact on Earth's infrastructure and technology.
The Aditya L1 mission is a truly international effort. The spacecraft is being built by ISRO, but it will also carry payloads from the United States, Europe, and Japan. The mission is a testament to the growing cooperation between space agencies around the world.
