The Aditya-L1 mission: ISRO’s first solar observatory in space

Abstract: Aditya-L1 is the first space mission of ISRO dedicated to solar observation. With seven payloads on boards, Aditya-L1 will provide the remote sensing observations of the Sun from Hard-X rays to infrared as well as in situ measurements of solar wind and interplanetary magnetic field. It aims to provide coronal magnetic field measurement using Spectro-polarimetric observation in the infrared Fe XIII line. It will measure the spatially resolved solar spectral irradiance in the near ultraviolet, central to our understanding of the Sun climate relations. This talk will discuss the mission’s capabilities with a focus on the Solar Ultraviolet Imaging Telescope (SUIT). SUIT will image the sun in 2000-4000 A band using 11 different filters, which is designed to study the coupling and dynamics of the lower solar atmosphere and obtain crucial inputs on the solar spectral irradiance in the NUV range.
