Aditya L1 set off on a 125-day journey to the Sun. At 11:45 am today the first Earth-bound firing will raise the orbit of the Aditya-L1 spacecraft.
Aditya L1 mission: The Indian Space Research Organization (ISRO) announced the date and time of the first Earth-bound firing to raise the orbit of the Aditya-L1 spacecraft at roughly 11:45 a.m. on Sunday, September 3, a day after the PSLV-C57 rocket carrying the orbiter successfully lifted off from Sriharikota, Andhra Pradesh.
A week after its illustrious Chandrayaan-3 lunar landing mission, the Indian Space Research Organization successfully launched its maiden solar mission, Aditya L1.
“Aditya-L1 started generating the power. The solar panels are deployed. The first EarthBound firing to raise the orbit is scheduled for September 3, 2023, around 11:45 Hrs. IST," ISRO tweeted.
Aditya L1 set off on a 125-day journey to the Sun. It will study several elements relating to Earsth’s nearest star, after being put into orbit by a PSLY rocket.
The spacecraft will be successfully positioned on its Halo orbit, L1, close to the Sun in four months. The mission's seven payloads will then start operating to begin tackling some of the most intriguing mysteries regarding the Sun.
Aditya L1's observations will also aid in establishing a link between the Sun's surface and the release of high-energy particles during solar storms.
The spacecraft will be put in a Low Earth Orbit after launch. The orbit will then become more elliptical, and the spacecraft will then use onboard propulsion to launch itself toward the Lagrange point (L1).
Spacecraft will leave the gravitational Sphere of Influence (SOI) of Earth as it moves closer to L1. After leaving SOI, the spacecraft will enter its cruise phase before being sent into a massive halo orbit around L1.
Aditya-L1 will be manoeuvred into an orbit that is unevenly shaped and nearly perpendicular to the line between the Earth and the Sun, where it will spend the remainder of its mission.
The mission seeks to learn more about the solar atmosphere, the dispersion of solar wind, temperature anisotropy, and more. The spacecraft will remain 1% of the Earth-Sun distance away, or 1.5 million kilometres, from Earth while always facing the Sun.
