Aditya-L1 is a Unique Mission: ISRO Chairman

Aditya-L1 spacecraft has been injected in an elliptical orbit of 235/19,500 km which is intended very precisely, by the PSLV, a unique mission mode here, with the upper stage of the PSLV taking two burn sequences for injecting the primary satellite for the first time,” ISRO Chairman S Somanath said Among others, it will send pictures of the sun for scientific experiments.

According to scientists, there are five Lagrangian points (or parking areas) between the Earth and the Sun where a small object tends to stay if put there. The Lagrange Points are named after Italian-French mathematician Joseph-Louis Lagrange for his prize-winning paper — “Essai sur le Problème des Trois Corps, 1772.” The Sun is a giant sphere of gas and Aditya-L1 would study its outer atmosphere. Aditya-L1 will neither land on the Sun nor approach it any closer, ISRO said.

The objectives of the Aditya-L1 mission include study of the coronal heating, solar wind acceleration, Coronal Mass Ejections (CME), dynamics of the solar atmosphere, and temperature anisotropy. Following Saturday’s launch Aditya-L1, weighing about 1,480.7 kg, stays in Earth-bound orbits for 16 days, during which it undergoes five maneuvers to gain the necessary velocity for its journey towards the Sun. Nigar Shaji, Project Director said it was a dream come true for the team Aditya L1. “I am extremely happy that Aditya L1 has been injected into the precise orbit flawlessly by PSLV as always. Aditya L1 solar panels are deployed and it is being normal,” she said.
