Mission Sun

BENGALURU, Sept 10: Aditya L1 spacecraft, India’s first space-based mission to check the Sun, efficiently underwent its third earth-bound manoeuvre within the early hours of Sunday, ISRO stated.
The area company’s Telemetry, Tracking and Command Network (ISTRAC) carried out the operation.
“The third Earth-bound manoeuvre (EBN#3) is performed successfully from ISTRAC, Bengaluru. ISRO’s ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation,” the Indian Space Research Organisation ISRO) stated in a publish on social media platform X.
The new orbit attained is 296 km x 71767 km, it stated, including the subsequent manoeuvre is scheduled on September 15, round 2 am.
Aditya-L1 is the primary Indian space-based observatory that may research the Sun from a halo orbit across the first Sun-Earth Lagrangian level (L1), which is positioned roughly 1.5 million km from the Earth.
The first and second earth-bound manoeuvres had been efficiently carried out on September 3 and 5, respectively. The spacecraft will bear another earth-bound orbital manoeuvres earlier than it’s positioned within the switch orbit in the direction of the Lagrange level L1.
The manoeuvres are required to be carried out through the spacecraft’s 16-day journey across the earth, throughout which it would achieve the rate vital for its onward journey to L1.
ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) had on September 2 efficiently launched Aditya-L1 from the Second Launch Pad of Satish Dhawan Space Centre, Sriharikota.
The spacecraft is predicted to reach on the meant orbit on the L1 level after about 127 days, the area company had stated quickly after the launch.
According to ISRO, a spacecraft positioned within the halo orbit across the L1 level has the benefit of constantly viewing the Sun with none occultation or eclipses. This will present a larger benefit of observing photo voltaic actions and their impact on area climate in real-time.
Aditya-L1 carries seven scientific payloads developed indigenously by the ISRO and nationwide analysis laboratories, together with the Indian Institute of Astrophysics, Bengaluru, and the Inter-University Centre for Astronomy and Astrophysics, Pune.
The payloads will observe the photosphere, chromosphere and the outermost layers of the Sun — the corona — utilizing electromagnetic, particle and magnetic area detectors.
Using the particular vantage level L1, 4 payloads will straight view the Sun and the remaining three will perform in-situ research of particles and fields on the Lagrange level L1, offering necessary information on the propagatory impact of photo voltaic dynamics within the interplanetary medium.
The fits of Aditya L1 payloads are anticipated to supply probably the most essential info to know the issue of coronal heating, coronal mass ejection, pre-flare and flare actions and their traits, dynamics of area climate, and propagation of particles and fields. (PTI)
According to scientists, there are 5 Lagrangian factors, or parking areas, between the Earth and the Sun the place a small object tends to remain put. (PTI)
The Lagrange Points are named after Italian-French mathematician Joseph-Louis Lagrange. These factors in area can be utilized by spacecraft to stay there with decreased gasoline consumption. (PTI)
At a Lagrange level, the gravitational pull of the 2 massive our bodies (the Sun and the Earth) equals the required centripetal drive required for a small object to maneuver with them. (PTI)
