Aditya-L1 Mission Payloads: Unlocking Solar Mysteries

The instruments of Aditya-L1 are tuned to observe the solar atmosphere mainly the chromosphere and corona. In-situ instruments will observe the local environment at L1. There are total seven payloads on-board with four of them carrying out remote sensing of the Sun and three of them carrying in-situ observation.

Payloads along with their major capability of scientific investigation.

The Aditya-L1 mission has seven payloads, which are

Visible Emission Line Coronagraph (VELC): This payload will image the solar corona in the visible light spectrum. It will help to study the structure and dynamics of the corona, and to understand the mechanisms that heat it up.
Solar Ultraviolet Imaging Telescope (SUIT): This payload will image the solar chromosphere and transition region in the ultraviolet light spectrum. It will help to study the heating and dynamics of these layers, and to understand the origin of the solar wind.
Solar Low Energy X-ray Spectrometer (SoLEXS): This payload will measure the spectrum of the solar X-rays. It will help to study the solar flares and coronal mass ejections, and to understand the physics of the solar atmosphere.
High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): This payload will measure the spectrum of the solar X-rays in the high-energy range. It will help to study the solar flares and coronal mass ejections, and to understand the acceleration of particles in the solar atmosphere.
Plasma Analyser Package For Aditya (PAPA): This payload will measure the properties of the solar wind plasma, such as its density, temperature, and composition. It will help to study the interaction between the solar wind and the Earth’s magnetosphere.
Aditya Solar wind Particle Experiment(ASPEX): This payload will measure the properties of the energetic particles in the solar wind, such as their energy, charge, and mass. It will help to study the acceleration of particles in the solar atmosphere, and the effects of these particles on the Earth’s atmosphere and environment.
Solar Irradiance Monitor (SIM): This payload will measure the solar irradiance, which is the total amount of energy emitted by the Sun. It will help to study the variability of the solar irradiance, and its effects on the Earth’s climate.
