Just days after India became the first country to successfully soft land near the South Pole of the Moon, India is preparing to launch a solar observation satellite aimed at better understanding the sun and its weather effects on Earth. ing.
It says the Aditya-L1 mission will “bring India to the forefront of solar space observations” and provide unprecedented data to scientists around the world. Helen Mason at the University of Cambridge.
The Indian Space Research Organization will launch the satellite on a PSLV-XL rocket from the Satish Dhawan Space Center on the east coast of the country on September 2.
Aditya-L1 is named after both the Hindu sun god and Lagrangian Point 1 (L1), which lies between the Earth and the Sun, where the gravitational pull from both celestial bodies is equal. It is positioned in an orbit around L1 so that it can observe the Sun continuously without obstruction, and can benefit from gravitational equilibrium by maintaining its position without using much fuel. Since the sun is much heavier than the earth, L1 is only 1% of his distance from the earth to the sun. The sun on average he is 150 million kilometers away.
The purpose of this mission was to study why the sun’s corona is so much hotter than its surface, I am investigating solar winds and flares. The satellite weighs 1,500 kilograms and carries seven scientific payloads, all developed in India. Four of the payloads will directly observe the Sun, and the remaining three will perform particle and magnetic field measurements from L1.
Scientists around the world are excited about the data, Mason said, but the spacecraft will have to wait 109 days after launch for it to reach its final position and begin taking measurements.
“This will be unique because it has some equipment on board that other satellites don’t,” Mason said. “All instruments are exciting and will push the boundaries of what we have at the moment.”
