ISRO To Perform Aditya L1’s First Earth-Bound Firing Today

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 week after its illustrious Chandrayaan-3 moon landing mission, the Indian Space Research Organisation successfully launched its maiden solar mission.

Latest information on the Aditya-L1 solar mission

1. “Aditya-L1 began producing power. The solar panels have been installed. On September 3 at about 11:45 a.m., the first Earth-bound firing to increase the orbit will take place, the ISRO said on Saturday.
2. The rockets will be fired during the Earth-bound motions, and as necessary, angles will be adjusted. 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 changing body weight) as the swing is falling down towards the earth. Aditya-L1 will slingshot around to its planned route towards L1 once it has gained enough speed.
3. According to the organisation, the PSLV properly positioned the Aditya-L1 satellite into its designated orbit.
4. According to the ISRO, Aditya-L1 would remain in its Earth-bound orbit for 16 days and perform five manoeuvres to increase its speed.

5. Aditya-L1 will next perform a trans-Lagrangian1 insertion operation, starting its 110-day trajectory to the location around the L1 Lagrange Point, the statement stated.
6. Once Aditya-L1 reaches the L1 point, a further manoeuvre will fix it to an orbit around L1, a gravitationally balanced place 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.
7. The organisation estimates that the Aditya-L1 mission will arrive at the observation location in four months. It will be positioned in a halo orbit around Lagrangian Point 1 (L1), 1.5 million kilometres from Earth,  in the direction of the Sun.

8. It is carrying seven different payloads, which will conduct a detailed study of the Sun. While four of the payload instruments will observe the light from the Sun, the remaining three will measure in-situ parameters of the plasma and magnetic fields.
9. Because of its advantageous position, Aditya-L1 will be able to continually watch the Sun without interference from eclipses or occultation, enabling researchers to track solar activity and its effects on space weather in real-time.
10. The data from the spacecraft will advance knowledge of the factors that influence space weather and pinpoint the series of events that precede solar eruptions.
