Today is a very important day for ISRO and the whole of India. Aditya-L1, sent by ISRO under the Solar Mission, will reach its destination L-1 point today i.e. Saturday (January 6, 2024) around 4 pm in the evening. This journey of 15 lakh kilometers towards the Sun, which started from Sriharikota, Andhra Pradesh, will reach its destination on September 2, 2023. This mission of ISRO is being watched with curiosity all over the world, because it has seven payloads, which will conduct a comprehensive study of solar phenomena.
What is ISRO’s Aditya L1 Mission ?
Aditya L1 is the first space-based Indian mission to study the Sun. This is a project run by ISRO to study the Sun. The spacecraft will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from Earth. This vehicle will revolve around the Sun in the same relative position and hence can continuously observe the Sun.
What is L-1?
Actually, Lagrange Point or L-1 is the region where gravity between the Earth and the Sun becomes zero or becomes inactive. After Aditya reaches the hello orbit, the Sun can be continuously monitored from there and information related to it can be obtained. According to ISRO, solar activities and its impact on space weather can be better estimated from the Halo Point.
The main scientific objectives of Aditya-L1 are to understand the origin, dynamics and propagation of coronal mass ejections and to help solve the coronal heating problem.
