India’s Aditya-L1 Solar Mission Executes Its Second Earth-bound Manoeuvre
12:23 05.09.2023 (Updated: 13:35 05.09.2023) Launched on September 2, India’s first-ever solar mission Aditya-L1 seeks to place a solar satellite in the Sun’s L1 orbit, which is nearly 1.5 million square km from the Earth.
India’s Aditya-L1 Solar Mission has successfully performed its second earth-bound manoeuvre from the Indian Space and Research Organization Telemetry, Tracking and Command Network (ISTRAC), the Indian space agency said in a statement.
“ISTRAC/ISRO's ground stations at Mauritius, Bengaluru and Port Blair tracked the satellite during this operation. The new orbit attained is 282 km x 40225 km,” it said.
The ISTRAC is responsible for providing major tracking support to satellites and launch vehicles, carrying out mission operations as well as providing other forms of operational support, according to ISRO.
The ISRO has said that the first earth-bound manoeuvre was successfully executed on September 3, a day after the
mission was launched from the Satish Dhawan Space Center off the coastline of Andhra Pradesh.
The next manoeuvre is scheduled for 10 September, it said.
The ISRO has noted that the mission would stay in Earth’s orbits for 16 days, during which it will undergo five manoeuvres to gain necessary velocity for its onward journey near the Sun.
After these five manoeuvres, Aditya-L1 will begin its 110-day trajectory to its destination around the L1 Lagrange point.
“Upon arrival at the L1 point, another manoeuvre would put Aditya-L1 to an orbit around L1, a balanced gravitational location between the Earth and the Sun,” the space agency explained.
The nominal mission life of Aditya-L1 is estimated to be five years.
What’s the Purpose of Aditya-L1 Mission?
The Aditya-L1 Mission is carrying seven payloads in order to observe the photosphere, chromosphere and Corona, the outermost layer of the Sun, in different wavebands.
The strategic placement of the
solar satellite is meant to ensure that Aditya-L1 will get an “uninterrupted view” of the Sun, according to ISRO.
“This location also allows the satellite to access solar radiation and magnetic storms before they are influenced by Earth's magnetic field and atmosphere,” ISRO explained.
Further, ISRO has estimated that L1 point’s “gravitational stability” would minimize the “need for frequent orbital maintenance efforts” and optimize the satellite’s operational efficiency.
