From the time this mission was conceptualized by Indian scientist in 2008, 7 years has passed. The mission has grown in scope and is now on the verge of getting formal approval from the Indian government.


The ambitious solar mission will study the sun’s outer most layers, the corona and the chromosphere, collect data about coronal mass ejection and more, which will also yield information for space weather prediction.

The project costs approximately Rs 400 crores and is a joint venture between ISRO and physicists from Indian Institute of Astrophysics, Bengaluru; Inter University Centre for Astronomy and Astrophysics, Pune; Tata Institute of Fundamental Research, Mumbai, and other institutes.

That's great. Looks like SOHO will have a new neighbor.

Not only has the mission got approval, it has had a name change. It is now known as Aditya-L1.


The Indian Space Research Organisation (ISRO) has recently announced that its first solar mission, named Aditya-L1, will be launched in 2019-20. The spacecraft aims to answer fundamental questions in solar physics by studying dynamic processes on the sun. It is slated to be blasted off into space from the Satish Dhawan Space Centre in Sriharikota, atop a PSLV-XL rocket.

The mission, introduced in 2008, was initially planned to be launched by 2015–16 and was designated Aditya-1. The original project envisioned the mission as a 882 lbs. (400 kg) satellite to be placed into a low Earth orbit (LEO) at an altitude of about 500 miles (800 km). Now, it is expected to be injected into the halo orbit around the Lagrangian point L1 of the Sun-Earth system, thus the mission was renamed to Aditya-L1.
