WS3 - Science with Aditya L1 mission

Title of workshop: Science with Aditya L1 mission
Organizers: Dipankar Banerjee (Indian Institute of Astrophysics, Bangalore) Email:
and Durgesh Tripathi (IUCAA,Pune) Email:
Rationale: Aditya-I is India's first dedicated scientific mission to study the sun. The Aditya-1 mission was conceived as a 400kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC) and was planned to launch in a 800 km low earth orbit. A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/ eclipses. Therefore, the Aditya-1 mission has now been revised to “Aditya-L1 mission” and will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth. The satellite carries additional six payloads with enhanced science scope and objectives. 

The project is approved and the satellite will be launched during 2019 – 2020 timeframe by PSLV-XL from Sriharikota. A combination of imaging and spectroscopy in Multi-wavelength will enhance our understanding of the solar atmosphere. Modeling of the three-dimensional structure of the solar corona requires an accurate empirical description of the coronal plasma parameters (densities, temperatures, and velocities) for the coronal plasma. The spectroscopic instruments on board Aditya will enable us to measure these plasma parameters for a diagnostics of the corona and the solar wind. The mission will provide vital data for space weather studies.

End of Workshop

Morning session will be dedicated to the science objectives of the individual payloads. Different payload team will present their payload details and the current status of development.

Afternoon session will focus on payload operation, different modes of observations and synergy between different payloads for co-ordinated observing campaign will be discussed.
