Today is a very special day for the Indian Space Research Organization (ISRO) because the country’s first space-based mission to study the Sun, ‘Aditya L1’, is going to be placed in the final orbit at a distance of about 15 lakh kilometers from the Earth. Is.
ISRO has made preparations to place Aditya-L1 in the final destination orbit.
Aditya-L1 is a satellite vehicle built at a cost of about Rs 400 crore, which weighs about 1,500 kg.
It will serve as the first space-based Indian observatory to study the Sun by being placed in a halo orbit about 15 lakh kilometers from Earth.
According to ISRO officials, the spacecraft will reach a ‘halo’ orbit around the ‘Lagrange Point 1 (L1) of the Sun-Earth system around 4 pm today. The ‘L1 point’ is approximately one percent of the total distance between the Earth and the Sun. The ‘Lagrange point’ is the region where gravity between the Earth and the Sun will become neutral. The ‘halo’ orbit is a periodic, three-dimensional orbit near one of the L1, L2 or L3 ‘Lagrange points’.
He said that the Sun can be seen continuously from the satellite in ‘Halo’ orbit around the ‘L1 point’. He said this would provide greater benefits in observing solar activities and its impact on space weather in real time.
An ISRO official said, “At around 4 pm on Saturday, Aditya-L1 will be placed in a ‘halo’ orbit around L1. “If we don’t do that, chances are it will probably continue its journey toward the sun.”
ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) successfully launched Aditya-L1 from the second launch pad of Satish Dhawan Space Center (SDSC) in Sriharikota on September 2.
During the four-month journey, the spacecraft passed through various stages and moved towards the Sun-Earth ‘Lagrange Point 1’ (L1), avoiding the Earth’s sphere of influence.
‘Aditya L1’ is designed to conduct remote observations of the solar corona and to conduct actual observations of the solar wind at ‘L1’ (Sun-Earth Lagrangian point) about 15 lakh kilometers from Earth.
Officials said that the main objective of this mission is to study the dynamics in the solar atmosphere, the heat of the Sun’s corona, solar earthquakes or ‘coronal mass ejections’ (CMEs) on the Sun’s surface, solar flare-related activities and their characteristics and in near-Earth space. To understand weather related problems.
