The India Indian Space Research Organisation (ISRO) will launch its first solar mission Aditya-L1 in 2019. It will be ISRO's and India's first dedicated mission to study the Sun.


The mission aims to put 1500-kg heavy class Aditya-L1 satellite into halo orbit around Lagrangian point L1, a point between Sun and Earth. This point is at a distance of about 1.5 million km from earth.

The mission will provide observations of Sun's Photosphere (soft and hard X-ray), Chromosphere (UV) and corona (Visible and NIR).  The particle payloads will study particle flux emanating from the Sun and reaching the L1 orbit and magnetometer payload will measure the variation in magnetic field strength at the halo orbit.   

The satellite will carry few additional payloads with enhanced scope and objectives. These payloads are: 

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