ISRO is going to launch its Solar Mission on September 2 at 11:50 AM to study the Sun. It has been named Aditya L1. ISRO has given this information on Monday.
Aditya L1 is designed for remote observation of the corona forming around the Sun. The spacecraft will be launched into space by PSLV-XL rocket from Sriharikota.
The Aditya spacecraft will be able to sense storms arising on the Sun by staying at the L1 i.e. Sun-Earth Lagrangian point. This point is about 15 lakh kilometers from Earth. It will take about 120 days i.e. 4 months to reach here.
It will orbit the Lagrangian point with seven payloads from different web bands, probing the photosphere, chromosphere and outermost layer, the corona.
Aditya L1 is Completely Indigenous
According to an ISRO official, Aditya L1 is a completely indigenous effort to be carried out with the participation of institutions from the country. The Indian Institute of Astrophysics (IIA) Visible Emission Line Coronagraph in Bengaluru produced its payloads. While the Inter-University Center for Astronomy and Astrophysics Pune has developed the Solar Ultraviolet Imager payload for the mission.
Why Aditya Spacecraft Will Be Sent to L1 Point Only
Aditya spacecraft will be placed in halo orbit between sun and earth. ISRO says that a satellite placed in a halo orbit around the L1 point can see the Sun continuously without any eclipse. With the help of this real time solar activities and space weather can also be monitored.
Aditya L1′s payloads are expected to provide information for understanding coronal heating, coronal mass ejections, characteristics of pre-flare and flare activities, particle movement and space weather.
What is L1?
Lagrange point 1 is commonly known as L-1. There are five such points between the Earth and the Sun, where the gravitational force of the Sun and the Earth balance and create a centrifugal force. In such a situation, if an object is kept at this position, it easily remains stable between the two and the energy is also low. The first Lagrange point is at a distance of 15 lakh km between the Earth and the Sun.
