Aditya-L1 is meant to observe the corona, which are the outer layers of the sun, extending to thousands of kilometres. “How the corona gets heated to such high temperatures is still an unanswered question in solar physics,” the ISRO stated on its website while sharing information about the mission.

Aditya-L1 — The strategy so far

• Will observe the corona, outer layers of the sun, extending to thousands of kms
• With additional experiments, will provide observations of the sun's photosphere, chromosphere
• Particle payloads will study particle flux emanating from the sun. These payloads will be placed outside the interference from the earth's magnetic field and can’t be useful in the low earth orbit

A proud moment for all. Congratulations to our scientists and engineers for furthering India’s indigenous space programme. May ISRO continue to conquer new frontiers. — Ram Nath Kovind, President

Cong invokes Nehru

This is a good time to remember the visionary move of India's first PM Pandit Jawaharlal Nehru to fund space research through INCOSPAR in1962 which later became ISRO. And also Dr Manmohan Singh for sanctioning the #Chandrayan2 project in 2008. Congress Twitter handle

Thank PM for this
