All preparations are underway for the launch of India's Sun Mission, Aditya-L1. The PSLV-C57 rocket has reached the launch pad for India's first solar mission. Launch rehearsals have been completed on August 30, 2023. All internal parts of the rocket have been inspected. Rocket is in perfect health.
The launch will take place on September 2, 2023 at 11:50 am. Aditya-L1 will be launched into Earth's Lower Earth orbit by ISRO's most trusted rocket PSLV-C57. It will then perform three or four orbit maneuvers directly out of Earth's Sphere of Influence (SOI). Then the cruise phase will begin. It will last a bit longer.
Aditya-L1 will then be inserted into Halo Orbit. Where the L1 point is. This point is located between the sun and the earth. But the distance from the sun to the earth is only 1 percent. The journey will take 127 days. It is considered difficult because it has to go into two large orbits.
The first difficult orbit is to go out of Earth's SOI. Because the earth pulls everything around it by its gravitational pull. Next is the cruise phase and capturing the L1 position in the halo orbit. If its movement is not controlled here, it will move straight towards the sun. and will burn out.
The sun has its own gravity. That is, the force of gravity. Earth has its own gravity. In space where the gravity of these two collide. Or rather, where the gravity of the earth ends. That's where the effect of the sun's gravity begins. The same point is called the Lagrange Point. India's Aditya will be deployed at Larange Point One, or L1.
Both have the range of gravity where a small object can stay for a long time. She will be trapped between the gravity of both. This reduces the fuel consumption of the spacecraft. He works longer. L1 is one percent of the total distance between the Sun and the Earth. That is 1.5 million kilometers. While, the distance from the sun to the earth is 150 million kilometers.
