What is Langres Point, where ISRO's Aditya L1 will go? Why is this point special?

ISRO is about to launch the Aditya L-1 mission on September 2 from the Satish Dhawan Space Center in Sriharikota, which will go to L-1 i.e. Langres Point. Till reaching this point from the earth, Aditya L-1 will travel for about 125 days. The 7 payloads that went with it will gather information about the Sun.

After the success of Chandrayaan-3, now Indian Space Research Organization i.e. ISRO is going to launch Aditya L-1, it will be launched from Satish Dhawan Space Center of Sriharikota on September 2, which will go to Langres Point i.e. L1 in Sun's Holo Orbit System. And will collect information about the Sun.

Aditya L-1 is ISRO's first solar mission. Which will cover a distance of 1.5 million kilometers towards the sun. Aditya-L1 spacecraft will take approximately 125 days to cover this distance. Along with the spacecraft, ISRO will send seven payloads which will provide many important information about the Sun to ISRO.

What is Langres Point i.e. L1

The distance of the Sun from the Earth is about 150 million kilometers. There are five points within this distance. These have been named from L1 to L5, Langroz Point i.e. L1 is its first point, which is 15 lakh kilometers away from the earth. This is the place where a balance is created between the gravity of the Earth and the Sun. That is, the Aditya L-1 which is being launched by ISRO will stabilize on L-1 and from there it will collect many important information about the Sun.

Why did ISRO choose L-1 point?

Due to the balance between Earth and gravity at the L-1 point, a centrifugal force is created, due to this force any spacecraft can remain stable at one place. That is why this place is considered most suitable for studying the Sun. The special thing is that this is considered to be a place between the two planets, due to which the cycle of day and night is not affected. In such a situation, it can do its work continuously for 24 hours.

Aditya L-1 will find out this

ISRO is sending seven payloads with Aditya L-1, these payloads will study the topology of the photosphere, corona and chromosphere, solar wind, coronal mass injection and magnetic field.

1. The photosphere is the lowest layer of the Sun's atmosphere that we see, its temperature is about 6 thousand degrees Celsius.

2. Just above the photosphere is a layer of gases called the chromosphere.

3. Corona is called the Sun's atmosphere, scientists claim that this region of the moon is a hundred times hotter than the photosphere.

4. Solar wind is the velocity of particles or plasma coming from outside the Sun which spread around in the space.

5. Topology refers to a layout or shape, Aditya-1 will find out about the topology of the Sun's magnetic field.

6. Coronal mass injections are called explosions on the surface of the sun, research will also be done about them.

This is how the journey will be completed

Aditya L-1 will be launched on September 2 from Satidhavan Space Center in Sriharikota. India's most successful rocket PSLV 57 will take it to the final orbit of the Earth and after that this spacecraft will be taken out of the Earth's gravity and injected into the L1 point and placed at one place. According to ISRO Chairman S Somnath, it will take at least 125 days i.e. about 4 months to complete this process.
