Aditya L1 reaches destination Lagrange Point-1
After landing on the moon, India has created another history. Aditya L1 of the Indian Space Research Organization (ISRO), which was on the Sun mission, has achieved a record by reaching its destination Lagrange Point-1 (L1). With this, Aditya-L1 was also placed in its final orbit. Here Aditya will study the Sun for two years and collect important data. This first Sun study mission of India was launched by ISRO on 2 September.
PM Modi has also expressed happiness over this success of ISRO. Praising ISRO by tweeting, he wrote that ‘India has achieved another milestone. India’s first solar observatory Aditya-L1 reaches its destination. A testament to the tireless dedication of our scientists in realizing one of the most complex space missions. This extraordinary achievement deserves appreciation. We will continue to push new frontiers of science for the benefit of humanity. He further said that he joins the nation in appreciating this extraordinary achievement.’
What is L-1 point?
The region around the L-1 point is known as the halo orbit, one of five places in the Sun-Earth system where the gravitational effects of the two bodies are in equilibrium. Broadly speaking, these are the places where the gravitational forces of both bodies balance each other. There is stability at these five places between the Earth and the Sun, due to which the object present here does not get trapped in the gravity of the Sun or the Earth.
The L-1 point is about 15 lakh kilometers away from the Earth. This is only 1 percent of the total distance between the Earth and the Sun. The total distance between the two bodies is 14.96 crore kilometers. According to an ISRO scientist, the halo orbit will rotate along with the Earth’s rotation around the Sun.
