Aditya-L1: India successfully launches first mission to the Sun

The Aditya-L1 took off from its launch pad in Sriharikota on Saturday morning.

by Geeta PandeyIndia has launched its first solar observation mission just days after making history by becoming the first country to land near the south pole of the moon.The Aditya-L1 took off from the Sriharikota launch pad at 11:50 am Indian time (06:20 GMT) on Saturday.It travels 1.5 million kilometers (932,000 miles) from Earth, or 1% of the distance between Earth and the Sun.According to the Indian Space Agency, the journey up this route will take four months.India’s first space mission to explore the solar system’s largest body is named after the Hindu sun god Surya, also known as Aditya. And L1 stands for Lagrangian Point 1, the exact place between the Sun and Earth that the Indian spacecraft is heading towards.

According to the European Space Agency, a Lagrangian point is a place where the gravitational forces of two large objects, such as the Sun and Earth, cancel each other out, allowing a spacecraft to “levitate.”Once Aditya-L1 reaches this “parking lot”, it could orbit the Sun at the same speed as the Earth. This also means that the satellite requires very little fuel to operate.India makes historic landing near lunar south pol Indian lunar rover walks on moon What did the Indian probe do on the Moon? On Saturday morning, thousands of people gathered at an observation gallery built by the Indian Space Research Organization (ISRO) near the launch site to witness the explosion.

It was also broadcast live on national television, with commentators calling it a “great” launch. Isro scientists said the launch was a success and that “its performance was normal.”

After an hour and four minutes of flight time, Isro declared the mission “successful.”

Isro boss Sledara Panicker Somanath said: “The journey continues. It’s a very long journey of 135 days. We wish you the best of luck.” Project leader Nigar Shaji said if Aditya-L1 achieves its goals, it will benefit the scientific community not only in India but also globally.Aditya-L1 orbits the Earth several times before launching towards L1.From this vantage point, he can always observe the sun and conduct scientific research, even if it hides during an eclipse.Isro declined to say how much the mission would cost, but Indian media reports put it at 3.78 billion rupees ($46 million, £36 million).

Trajectory of Aditya-L1

Isro said the orbiter will carry seven scientific instruments to observe and study the solar corona (the outermost layer). The photosphere (the surface of the Sun, or the part visible from Earth) and the chromosphere (the thin layer of plasma between the photosphere and the corona). The research will help scientists understand in real time solar activity, such as solar winds and solar flares, and their impact on Earth and near-space weather.

Former Islo scientist Mirswamy Anadurai says the sun constantly influences the weather on Earth through radiation, heat, particle flows and magnetic fields. At the same time, he says, it also affects space weather.

“Space weather affects how effectively satellites operate. Solar winds and storms can affect satellite electronics and even bring down power grids.” But there are gaps in our knowledge of space weather,” India has more than 50 of her satellites in space, providing India with many vital services including communication links, weather data and helping to predict pest infestations, droughts and impending disasters. According to the United Nations Outer Space Agency (UNOOSA), approximately 10,290 satellites remain in orbit around the Earth, of which nearly 7,800 are currently in operation.

Aditya helps us better understand the star on which our lives depend, says Annadurai, and even gives us a preview.

“If we can know the activity of the sun, such as solar winds and solar flares, in the next few days, we can keep satellites out of danger.” This helps extend the life of satellites in space. ”

The mission will help advance our scientific understanding of our 4.5 billion year old star, the Sun.
Most importantly, he added, the mission will help advance scientific understanding of the Sun, the 4.5-billion-year-old star that holds our solar system together.

The Indian solar mission came just days after the world’s first spacecraft successfully landed near the moon’s south pole.

With this, India became the fourth country in the world to achieve a soft landing on the moon after the United States, the former Soviet Union and China.

If Aditya-L1 succeeds, India will join a select group of countries already conducting solar exploration.

Japan was the first country to launch a mission to study solar flares in 1981, and the US space agency NASA and the European Space Agency (ESA) have been monitoring the sun since the 1990s. In February 2020, NASA and ESA jointly launched the Solar Orbiter to study the Sun up close and collect data that scientists say will help us understand the driving forces behind its dynamic behavior.

And in 2021, NASA’s newest Parker Solar Probe spacecraft will make history as the first to fly inside the outer atmosphere of the Sun, the corona.

What is Aditya-L1’s goal?

The main objective of this mission is to improve India’s 24-hour solar observation capabilities. Observing the sun unobstructed helps us keep a close eye on solar activity. For this purpose the Aditya L1 is equipped with 2 main instruments and 5 minor instruments.
