Teams from Spain, Belgium, Poland, Italy and Switzerland have worked for the Proba-3 mission. This has cost about 20 crore euros i.e. about Rs 1,778 crore. It will study the gap formed between the inner corona and outer corona of the Sun. It will be launched from 2 satellites simultaneously. Both the satellites will be at a distance of 150 meters from each other.
Special features of Proba-3 mission-
PROBA-3 is the world’s first precision formation flying satellite, which means not one but two satellites will be launched here. The first is Coronagraph Spacecraft and the second is Occulter Spacecraft. The weight of both of them is 550 kg. After launching both the satellites will separate. These will later be positioned together to form a solar coronagraph. It will study the Sun’s corona in detail. Let us tell you that the outer atmosphere of the Sun is called the Corona of the Sun.
