Aditya -L1 Mission: ISRO’s maiden solar mission heading toward the Sun
1/5 ISRO's Aditya-L1 mission, launched on September 2, 2023, marks India's inaugural dedicated mission to study the Sun's photosphere, chromosphere, and corona. The spacecraft is now en route to its ultimate destination, the Sun-Earth Lagrange Point 1 (L1).   (ANI)

2/5 Lagrange points are unique positions in space where the gravitational forces of two massive bodies, in this case, the Sun and Earth, perfectly balance the centripetal force required for a smaller object, like a spacecraft, to remain in sync. These points minimize the need for orbit corrections and fuel consumption, making them ideal for scientific missions. (ANI)

This positioning enables continuous observation of both primary bodies, unbroken communication with Earth, and an unobstructed view of celestial objects. (ANI)

Several operational spacecraft currently occupy this location, playing a crucial role in providing early warnings about adverse space weather events, safeguarding orbiting space assets and ground-based infrastructure.

Aditya-L1 mission spacecraft is now in its trajectory towards a point where the Sun-Earth system is at equilibrium to study various phenomena. In a recent update, the Aditya-L1 spacecraft has captured the first-ever high-energy X-ray of solar flares during its monitoring phase. Till now, the spacecraft has made successful manoeuvres including a Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre and now it will be placed at the halo orbit of Lagrange Point 1. Know what ISRO uncovered with the X-ray image of the Sun.

Aditya-L1 mission findings

ISRO shared an update about the Aditya-L1 mission through their official X (Formerly Twitter) handle saying that the HEL1OS spectrometer captured the first high-energy X-ray of solar flares along with GOES X-ray light curves. The Indian space agency further reported that the spectrometer attached to the spacecraft was responsible for recording the highest phase of the solar flare on October 29, during its first observation period.

ISRO reported that such solar flares are sudden occurrences of the Sun's outer layers. These flares emit harmful radiations across the electromagnetic spectrum – radio, optical, UV, soft X-rays, hard X-rays and gamma-rays. Right now the HEL1OS is in fine-tuning of thresholds and calibration operations phase and it will continue to study the Sun's high-energy X-ray activities. ISRO said, “HEL1OS data enables researchers to study explosive energy release and electron acceleration during impulsive phases of solar flares.”

About HEL1OS spectrometer

The High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) is designed to study the Sun's explosive energy release, electron acceleration, and transport during solar flares with fast timing measurements and high resolution spectra. The instrument was developed by the Space Astronomy Group of the U. R. Rao Satellite Centre, ISRO, Bengaluru, in collaboration with different centre entities.

The HEL1OS spectrometer has been studying the Sun's solar flare activities since October 27, and it captured the highest energy of the flare on October 29, 2023, giving insights into the activities of the Sun. ISRO will be providing more information on the findings.
