Payloads and their science objectives:
Visible Emission Line Coronagraph (VELC):
- To study the diagnostic parameters of solar corona and dynamics and origin of Coronal Mass Ejections (3 visible and 1 Infra-Red channels); magnetic field measurement of solar corona down to tens of Gauss.
Solar Ultraviolet Imaging Telescope (SUIT):
- To image the spatially resolved Solar Photosphere and Chromosphere in near Ultraviolet (200-400 nm) and measure solar irradiance variations.
Aditya Solar Wind Particle Experiment (ASPEX):
- To study the variation of solar wind properties as well as its distribution and spectral characteristics.
Plasma Analyser Package for Aditya (PAPA):
- To understand the composition of solar wind and its energy distribution.
Solar Low Energy X-ray Spectrometer (SoLEXS):
- To monitor the X-ray flares for studying the heating mechanism of the solar corona.
High Energy L1 Orbiting X-ray Spectrometer (HEL1OS):
- To observe the dynamic events in the solar corona and provide an estimate of the energy used to accelerate the particles during the eruptive events.
- To measure the magnitude and nature of the Interplanetary Magnetic Field.
