ISRO will increase the orbit of Aditya L1 today

Aditya Spacecraft was launched on September 2 at 11.50 am from the Satish Dhawan Space Center in Sriharikota by PSLV-C57's XL version rocket. The spacecraft was successfully placed in Earth's orbit 63 minutes and 19 seconds after launch.

After about 4 months, it will reach Lagrange Point-1, 15 lakh km away. There is no effect of eclipse at this point, due to which research on the sun can be done easily from here. 

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 is balanced and centrifugal force is created.
In such a situation, if an object is kept at this place, then it easily starts revolving around that point. The first Lagrange point is at a distance of 1.5 million kilometers between the Earth and the Sun. There are a total of 5 such Lagrange points.

Eclipse neutralized at L1 point, hence sending here
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. It will reach L1 point on 6 January 2024.

Aditya has 6 payloads:
1. PAPA i.e. Plasma analyzer package for Aditya: Will study the hot winds of the sun.
2. VELC i.e. Visible Line Emission Coronagraph: Will take high definition photos of the sun.
3. SUIT i.e. Solar Ultraviolet Imaging Telescope: Will take photos of the sun's ultraviolet wavelength.
4. HEL10S i.e. High Energy L1 Orbiting X-ray Spectrometer: Will study high-energy X-rays.
5. ASPEX i.e. Aditya Solar Wind Particle Experiment: Will study alpha particles.
6. MAG i.e. Advanced Tri-Axial High Resolution Digital Magnetometers: Will study magnetic fields.

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.

The sun releases energy in two ways:
The normal flow of light that illuminates the Earth and makes life possible.
A blast of light, particles and magnetic fields that can damage electronic items.
This is called solar flare. When this flare reaches the Earth, the Earth's magnetic field protects us from it. If it collides with the satellites present in the orbit, then they will get damaged and everything from the communication system on the earth will come to a standstill.
The largest solar flare ever hit the Earth in 1859. This is known as the Carrington event. Then the global telegraph communication was affected. That is why ISRO wants to understand the Sun. If there is more understanding of solar flare then steps can be taken to deal with it.
