Countdown begins for 'Aditya-L1' mission
The countdown for ISRO’s ambitious Sun Mission i.e. Aditya-L1 has started. This mission of ISRO will be launched from Sriharikota Space Station in Andhra Pradesh on September 2 at 11.50 a.m. with the help of a PSLV-XL rocket. Aditya will take the L-1 spacecraft to the L-1 point by covering one percent of the distance between the Earth and the Sun…

After the successful landing of Chandrayaan-3 on the lunar surface, the country’s eyes are now on ISRO’s Sun Mission i.e. Aditya-L1. Its countdown has also started. This ambitious mission of ISRO will be launched on September 2 with the help of the PSLV-XL rocket. It will reach its point L1 exactly 127 days after launching. After reaching this point, Aditya-L1 will start sending very important data.
Before the launch of the mission, ISRO Chief S Somnath said, ‘Preparations are on to launch the Aditya L-1 mission. The mission will be launched on September 2 at 11:50 a.m. from Sriharikota Space Station in Andhra Pradesh. Aditya will take the L-1 spacecraft to the L-1 point after covering one percent of the distance between the Earth and the Sun. L1 is one percent of the total distance between the Sun and the Earth. Means 15 lakh kms. Whereas, the distance of the earth from the sun is 150 million kilometers.

ISRO Chief further said that the Aditya L-1 mission is going to be ISRO’s first dedicated space mission to observe the Sun. Preparations for the launch have reached the final stage. The rocket and satellite are ready. Rehearsals for the launch have also been completed. ISRO’s most reliable rocket PSLV-C57 will launch Aditya-L1 into the Earth’s Lower Earth Orbit. After this, after doing three or four-orbit maneuvers, it will go directly out of the Earth’s Sphere of Influence (SOI). Then the cruise phase will start. This will last a little longer.
Aditya-L1 will be put in Halo Orbit. Where the L1 point is. This point is located between the sun and the earth. But compared to the distance of the Earth from the Sun, it is only 1 percent. It is going to take 127 days for this journey. It is considered difficult because it has to go in two big orbits.
ISRO Aditya L1 Mission: Excitement among people before the launch of the L1 mission
There is enthusiasm among people before the launch of the L1 mission. People have started arriving to see the mission. A young man said that he was very excited to be here for the launch of the Aditya-L1 mission.

Big danger if speed is not controlled
The first difficult orbit is to go outside the Earth’s SOI. Because the earth pulls everything around it with its gravitational force. This is followed by the cruise phase and capturing the L1 position in the hello orbit. If its speed is not controlled here, it will go straight towards the sun. And it will burn away.
Where will the Aditya-L1 mission be stationed?
The sun has its own gravity. That means gravitational force. Earth has its own gravity. In space, the gravity of these two collides. Or rather, where the Earth’s gravity ends. The effect of the sun’s gravity starts from there. This point is called Lagrange Point. India’s Aditya Larange will be deployed at Point One i.e. L1.
Will cover 1% distance between Earth and the Sun
Due to the limit of gravity of both, a small object can remain there for a long time. She will be stuck between the gravity of both. Due to this, the fuel of spacecraft is used less. He works long hours. L1 is one percent of the total distance between the Sun and the Earth. Means 15 lakh kms. Whereas, the distance of the earth from the sun is 150 million kilometers. Our solar system gets energy only from the sun. Its age is considered to be about 450 crore years. Life on Earth is not possible without solar energy. All the planets in the solar system are sustained by the gravity of the Sun. Otherwise, they would have been floating in deep space long ago.
Why does the sun continuously breathe fire?
Nuclear fusion takes place in the center of the sun. That’s why the sun is seen spewing fire all around. A little above the surface means the temperature of its photosphere remains up to 5500 degrees Celsius. The study of the sun is so that due to it the understanding of the rest of the planets of the solar system can also increase.
Why is it important to know space weather?
Due to the sun, there is a continuous flow of radiation, heat, magnetic field, and charged particles on the earth. This flow is called the solar wind. They are made of high-energy protons. Solar magnetic field is detected. Which is very explosive. This is where Coronal Mass Ejection (CME) occurs. Because of this, there is a possibility of many types of damage to the earth due to the coming solar storm. Therefore it is important to know the weather of space. This weather is formed and worsens due to the sun.
