ISRO's first ever Sun mission in 2019-20

Chennai

The project, aimed at comprehensive understanding of the dynamical processes of the sun, was approved and the Aditya-L1 mission, would be launched during the 2019-2020 timeframe by  ISRO's workhorse launch vehicle PSLV-XL from the spaceport  of Sriharikota, about 80 km fom here.

ISRO, in a release posted at its website today, said 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. 

The Aditya-1 mission has now been revised to 'Aditya-L1 Mission' and will be inserted in a halo orbit around the L1, which was 1.5 million km from the Earth.
