LIVE: ISRO's Aditya L1 reaches Earth's orbit

The rocket released Aditya into an orbit of 235 x 19500 Km after 63 minutes 19 seconds. After about 4 months it will reach Lagrange Point-1. There is no effect of eclipse at this point, due to which research on the sun can be done easily from here. The estimated cost of this mission is Rs 378 crore.

Know the journey of Aditya L1 in 5 points

1. PSLV rocket launched Aditya into Earth orbit of 235 x 19500 Km.
2. Will remain in Earth's orbit for 16 days. Will raise the orbit by firing the thruster 5 times.
3. Again Aditya's thrusters will fire and it will move towards L1 point.
4. Aditya Observatory will reach near this point after 110 days of travel
5. Through thruster firing Aditya will be put into the orbit of L1 point.

What is Lagrange Point-1 (L1)?
Lagrange points are named after Italian-French mathematician Joseph-Louis Lagrange. It is colloquially known as L1. There are five such points between the Earth and the Sun, where the gravitational force of the Sun and the Earth balances out and becomes a centrifugal force.
In such a situation, if any object is kept at this place then it easily remains stable between the two and less energy is also required. The first Lagrange point is at a distance of 1.5 million kilometers between the Earth and the Sun.

Eclipse neutralized at L1 point, hence sending here
Aditya spacecraft will be placed in a halo orbit between the Sun and the Earth. ISRO says that a satellite placed in a halo orbit around the L1 point can see the Sun continuously without any eclipse. With this, real-time solar activities and space weather can also be monitored.
Aditya L1's seven instruments will provide information to understand coronal heating, coronal mass ejection, characteristics of pre-flare and flare activities, movement of particles and space weather. Aditya L-1 will study the solar corona and its heating mechanism.

Aditya L1 is completely indigenously built
According to an ISRO official, Aditya L1 is a completely indigenous effort to be made with the participation of the country's institutions. The Indian Institute of Astrophysics (IIA) Visible Emission Line Coronagraph in Bangalore created its payloads. While the Inter-University Center for Astronomy and Astrophysics Pune has developed the Solar Ultraviolet Imager payload for the mission.

Why is the study of the Sun necessary?
The Sun is the center of the solar system in which our Earth exists. All the eight planets revolve around the Sun. There is life on earth because of the Sun. Energy flows continuously from the Sun. We call them charged particles. By studying the Sun, it can be understood how changes in the Sun can affect space and life on Earth.
