Aditya L1: The Polar Satellite Launch Vehicle, or PSLV-C57.1 rocket carrying the orbiter successfully launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota, according to the Indian Space Research Organisation (ISRO). The first Earth-bound firing to raise Aditya-L1’s orbit is scheduled for around 11:45 am on Sunday.
A Solar Mission with Promising Power Generation and Earth-Bound Firing
A week after its illustrious Chandrayaan-3 lunar landing mission, the Indian Space Research Organisation successfully launched its maiden solar mission. “Aditya-L1 started generating the power. The solar panels are deployed. The first Earth-Bound firing to raise the orbit is scheduled for September 3 around 11:45 hours,” the ISRO said on Saturday. The Earth-bound motions will involve launching the rockets and maybe adjusting the angles. Perhaps the best way to understand how this will function is to use the example of a swing. To make the swing go higher, pressure is applied (by shifting body weight) as the swing is falling down towards the earth. Aditya-L1 will slingshot around to its intended path towards L1 once it has gained enough speed.
Aditya-L1’s Journey from Earth-Bound Orbit to the L1 Lagrange Point
According to the agency, the PSLV successfully manoeuvred the Aditya-L1 satellite into its intended orbit. According to the ISRO, Aditya-L1 would remain in its Earth-bound orbit for 16 days and perform five manoeuvres to increase its speed. Aditya-L1 will then perform a trans-Lagrangian1 insertion operation, starting its 110-day trajectory to the location around the L1 Lagrange Point, the statement stated. When Aditya-L1 reaches the L1 point, another manoeuvre will lock it into an orbit around L1, which is a gravitationally balanced region halfway between the Earth and the Sun. The satellite will spend the entirety of its mission life in an erratic orbit around L1 in a plane that is nearly perpendicular to the line connecting the Earth and the Sun. The Aditya-L1 mission is anticipated to arrive at the observation location in four months, per the agency. It will be positioned in a halo orbit 1.5 million kilometres from the Earth in the direction of the Sun, known as Lagrangian Point 1 (or L1).
Seven Payloads for In-Depth Solar Exploration
It is equipped with seven different payloads that will investigate the Sun in great detail. Three of the payload equipment will measure in-situ parameters of the plasma and magnetic fields, while the other four will examine the Sun’s light. Aditya-L1 will be able to continually watch the Sun from this advantageous location without being constrained by eclipses or occultation, enabling researchers to track solar activity and its effects on space weather in real-time. The data from the spacecraft will contribute to a better understanding of the factors that cause space weather and identify the series of events that precede solar eruptive events.
