According to ESA, the ‘PROBA-3’ mission will study the outermost and hottest layer of the Sun’s atmosphere. The outer atmosphere of the Sun is called the Sun’s corona. ISRO’s commercial arm NewSpace India Limited (NSIL) is cooperating in this mission. ISRO has already launched two Proba missions. The first launch was PROBA-1 in 2001. The second PROBA-2 mission was launched in 2009. ISRO was successful in both the missions.
Proba-3 mission will be launched from two main spacecraft. The first is Occulter, whose weight is 200 kg. The second spacecraft is Coronagraph, which weighs 340 kg. After launching both the satellites will separate. These will later be positioned together to form a solar coronagraph.

The total cost of this mission is said to be around 200 million euros. Proba-3 mission will run for two years.
