The Indian Space Research Organisation(ISRO) would be launching a 400 kg satellite, Aditya-L1, as part of its first ever Indian mission to study the sun.

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

Good development, make us proud.
Any step toward the betterment of the Mankind should be welcomed and appreciated.

Good Luck !!

All the required technology is there, postponing the mission by 3-4 years doesn't make much sense to me.

Funding probably.

There is specific time window for these missions to fulfill certain mission parameters.,

for example, assuming a probe is sent to study sun's surface, below conditions would be kept in mind:
1. the point of time when distance between earth and sun is shortest.
2. point of time when above condition is satisfied plus there no gravitational influence from other celestial bodies like Mercury or Venus etc.


Mars mission had this specific time window too, and loss of that specific time window would mean waiting for a couple of years for the time window to appear again.
