Solar spacecraft Aditya-L1 will reach L1 point on January 6: Isro chairman | India News – Times of India


NEW DELHI: India’s maiden solar spacecraft Aditya-L1 will reach its destination, the Lagrangian point (L1), on January 6, Isro chairman S Somanath has disclosed. The L1 point is located 1.5 million km from the Earth and from this point, the spacecraft will be able to study the outer atmosphere of the Sun by viewing it constantly and uninterrupted without any eclipse.
“Aditya-L1 will enter the L1 point on January 6.That is what is expected. Exact time will be announced at an appropriate time,” Somanath told the media on the sidelines of the Bharatiya Vigyan Sammelan in Ahmedabad on Friday. “When it reaches the L1 point, we have to fire the engine once again so that it does not go further. It will go to that point, and once it reaches that point, it will rotate around it and will be trapped at L1,” he explained.

Isro launched the Solar mission from the Sriharikota spaceport on September 2. Once the spacecraft, loaded with seven key scientific instruments, reaches the L1 point, it will help measure various events happening on the Sun. The L1 location will allow the Aditya spacecraft to access solar radiation and magnetic storms before they are influenced by the Earth’s magnetic field and atmosphere.

“Once it is successfully placed on L1 point, it will be there for the next five years, gathering all the data which are very important not for India alone but for the entire world. The data will be very useful to understand the dynamics of the Sun and how it affects our life,” the Isro chairman said.

The spacecraft will study solar upper atmospheric dynamics, chromospheric and coronal heating, physics of the partially-ionised plasma, initiation of the coronal mass ejections, and flares. It will also observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun, magnetic field topology and magnetic field measurements in the solar corona.

Somanath also talked about India’s own space station in future. He said Isro has made a plan to build an Indian space station, called ‘Bharatiya space station’ during the ‘Amrit Kaal’ as per PM Narendra Modi‘s instructions.
