ISRO to launch Aditya L1, Know what L1 means.

The Indian Space Research Organisation (ISRO) has published the launch information for its groundbreaking solar mission, Aditya-L1, marking a giant step toward space exploration. The mission intends to increase our knowledge of the Sun and its behaviour, advancing critical understanding of solar phenomena and space weather.

The launch of Aditya-L1, the first space-based Indian observatory to study the Sun, is scheduled for September 2, 2023, at 11:50 Hrs. IST from Sriharikota.

ISRO to launch Aditya-L1 with goals of thoroughly investigating the Sun-Earth link with a focus on the solar corona and its outermost layer. The mission promises to provide unhindered views of the Sun’s dynamic processes since it is positioned at the Lagrangian point L1, which keeps a constant distance from the Sun and Earth.

What is L1 in Aditya L1 first space-based Indian observatory?

L1 in Aditya L1 stands for Lagrangian point L1. It is a zone of gravitational equilibrium between Sun & Earth. Aditya L1 will observe the Sun without interruption while remaining safely away from the radiation from Earth. The spacecraft can acquire essential information about solar emissions, solar winds, and magnetic activity from this advantageous position, which helps us better understand how space weather dynamics affect the technological systems on Earth.
