LaunchPSLV-XL
OrbitLagrange point-L1 between Sun & Earth

Important milestone: India one of handful nations that have solar observatory, Capability to launch complex mission/perfect injection into L1 Halo orbit

Major objectives:

1Solar coronograph - Aditya L1 will produce one of the largest solar coronograph

(II) Solar spectrum study - to see the various emissions of sun

(III) Solar plasma study and observe patterns in plasma emission

(IV) Sunspots and solar cycle monitoring by ensuring accurate detection of solar maxima and solar minima

Challenges:

1Accurate placement of Aditya-L1 into L1 orbit - achieved successfully

(II) Deep space working of instruments near the Sun and high plasma bombardment

(III) Accurate readings and sending data in real time

ISRO had overcome all the above challenges and shown that it can undertake complex solar missions like NASA, ESA.
