Aditya-L1: The Sun-Earth L1 point will soon be reached by Aditya-L1, India’s first satellite-based solar observatory, according to the Indian Space Research Organisation (Isro) on Tuesday. The TL1I manoeuvre, or Trans-Lagrangean Point 1 Insertion, was carried out successfully by the spacecraft. It will take roughly 110 days for it to travel from here to the Sun-Earth Lagrange point 1 (L1), which is located roughly 15 lakh km distant from Earth.
A Close Look at the Sun’s Layers and Space Weather Dynamics
The photosphere, chromosphere, and corona of the Sun will be investigated by the Aditya-L1 mission, which was launched on September 2. Additionally, it will look into the dynamics of space weather and the transmission of fields and particles. The spacecraft has successfully performed four manoeuvres that are Earth-bound, with the TL1I kicking off its ascent to the L1 point. The L1 point is ideally situated for viewing solar activity and how it affects space weather since it provides a continuous view of the Sun. Aditya-L1 will enter a halo orbit at this moment and stay there for the duration of its mission. Through careful setup, the Sun can be seen continuously without interference from eclipses or occultations.
Aditya-L1’s Quest Aligns with Understanding Lagrange Points
The goals of the project are in line with scientists’ efforts to comprehend the complex dynamics of the region of space around the Earth and Sun. The gravitational pull of the Sun and Earth and the centripetal force necessary for small objects to continue moving in synchronised motion with them are perfectly balanced at the Lagrange points, which bear the name of the eminent Italian-French mathematician Joseph-Louis Lagrange.
