India Indian Space Research Organisation (ISRO) is ready to launch its first mission on sun with the Aditya-L1 mission.
- The mission will be launched in 2019
- The satellite carrying six payloads will be launched from Sriharikota in Andhra Pradesh on the PSLV- XL launch vehicle.
- It will be launched into the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system.
- L1 point is 1.5 million kilometres away from the earth
- This orbit has the advantage of allowing continuous monitoring of the sun.
- Aditya-L1 is expected to be the very first to study from space two months from the time of launch, the magnetic field of the sun’s corona.
- The mission will carry seven payloads,consisting of a coronagraph, equipment that will image the sun using ultraviolet filters, X-ray spectrometers, and particle samplers all being made within the country.
The Seven Payloads are:
- Visible Emission Line Coronagraph (VLEC) is the largest payload, or instrument will view the sun more closely than has been done before even by SOHO.
- Solar Ultraviolet Imaging Telescope (SUIT) will image the sun in all wavelengths.
- The ultraviolet (UV) imaging payload will capture the sun using UV filters, something that is not possible from Earth.
- Aditya Solar wind Particle EXperiment (ASPEX) and Plasma Analyser Package for Aditya (PAPA) will study aspects that affect space weather. the origin of solar wind ions
- Solar Low Energy X-ray Spectrometer (SoLEXS) will be used for monitoring X-ray flares for studying the heating mechanism of the solar corona
- High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) will be used to study hard X-ray emission from 10 keV to 150 keV during the impulsive phase of solar flares
