Aditya-L1 Mission And Launched
India became the first country in the world to make a successful soft landing on the south pole of the moon a few days ago. The euphoria of that success still overwhelms the countrymen. Meanwhile, another feather was added to India's crown. Aditya L1 was launched by ISRO.
Aditya broke the mystery of Rabir today, Saturday, September 2. India's first solar space observatory mission was launched on board the Polar Satellite Launch Vehicle (PSLV) XL from the Satish Dhawan Space Center in Sriharikota. Aditya will be in a halo orbit about 15 million kilometers from Earth. Aditya L1 will probe the surface of the sun. The solar probe operated by Isro will attempt to ascertain what impact solar storms may have on Earth.
But what is the goal of this mission?
The mission aims to observe solar activity and its effects on space weather. The sun's upper atmosphere and its interaction with the solar wind will also be examined.
What is the solar wind?
According to NASA, the solar wind is a constant stream of particles and magnetic fields emanating from the sun. This solar wind flows throughout the solar system and can reach the planet's surface unless it is deflected by the atmosphere, magnetic field, or both.
On Earth, the magnetic field protects us from the solar wind. But sometimes, when the solar wind intensifies, it leaks and can cause the aurora or halo visible in the sky near the poles. When it comes to the moon, the solar wind hits its surface directly due to its thin atmosphere. Small bubbles of magnetic field across the moon's surface cause only slight deviations. "This bombardment deposited material that could form water," NASA said.
Why is the experiment with the solar wind important?
ISRO's Aditya-L1 spacecraft is carrying seven payloads. which includes a payload called the Aditya Solar Wind Particle Experiment (ASPEX). The payload will be tasked with measuring the composition and dynamics of the solar wind.
According to ISRO, the solar wind and other explosive solar events, such as coronal mass ejections (CMEs), can affect the nature of space. When Earth's magnetic field interacts with CMEs, magnetic disturbances can occur near our planet. This can affect the performance of space assets such as satellites.
After the moon, ISRO's next mission is the sun. Aditya L1 will keep an eye not on the sun but far away from it. Aditya L1 departed Sriharikota in Andhra Pradesh for Lagrange Point L1 at 11:50 a.m. as planned. Aditya L1 is launched aboard the Polar Satellite Launch Vehicle, or PSLV-C57 rocket. It will take 125 days.
Aditya will be located in a halo orbit about 1.5 million km, or 15 lakh km, away from the Earth. It is known that this Aditya L1 will examine the corona of the sun, or the surface. ISRO's solar probe will try to find out what effect solar storms can have on Earth.
For the time being, the sun's outer atmosphere will be observed.
Aditya will be located at Lagrange Point L1 between the Sun and Earth. The L1 Lagrange point is a place in space where the gravitational pull of two massive objects, such as the Sun and Earth, is in balance and can accommodate a small object, such as a spacecraft. According to scientists, the sun can be seen unobstructed from this point. The test will run for five years. Earlier, ISRO Chairman S. Somanath said that the mission would take 125 days to reach the correct radius. If this mission is successful, much important information about Madhyamani and the solar system will be revealed. For the time being, the sun's outer atmosphere will be observed.
This is the first time that India is sending a space observatory for solar research, i.e., observing the sun. It is known that ISRO has developed this spacecraft in such a way that it can observe the remote parts of the solar corona perfectly. The Aditya L-1 spacecraft will also study the solar atmosphere in addition to this. Another objective of ISRO's solar mission is to study the solar wind. On occasion, this solar wind causes issues for Earth. To common people, this solar wind is actually known as the aurora. There will be a total of seven payloads on Aditya L-1. Four of these will collect data from the sun. Will mainly research the chromosphere and corona. The remaining three will be used for other purposes. You can check here-
