ISRO’s Aditya-L1 will join NASA’s Solar and Heliospheric Observatory (SOHO) at L1 point

India's maiden solar mission successfully lifted off today, September 2 at 11:50 AM IST from the Satish Dhawan Centre in Sriharikota. The spacecraft, named Aditya-L1, has embarked on a 1.5 million-kilometer journey to the Sun, where it will be placed in the halo orbit around the first Lagrange point (L1) of the Sun-Earth system. Interestingly, Aditya-L1 will join four other spacecraft that are already placed in similar orbits - the Solar and Heliospheric Observatory (SOHO), Advanced Composition Explorer (ACE), Global Geospace Science (GGS) Wind and the Deep Space Climate Observatory (DSCOVR).

Here's how the Indian Space Research Organization (ISRO)'s Aditya-L1 compares to NASA and ESA's Solar and Heliospheric Observatory (SOHO).

Aditya-L1 will now travel approximately 1.5 million kilometres to the Sun. The spacecraft will be placed in a halo orbit around the Lagrange 1 (L1) point for a 5-year mission. The mission aims to unravel the mysteries of the Sun, such as the cause behind Coronal Mass Ejections (CMEs), solar flares, solar weather, and more.

According to ISRO, Aditya-L1 is carrying seven payloads to study the photosphere, chromosphere and coronal layer of the Sun, which will be done using electromagnetic and particle directors. All the payloads will help scientists develop a greater understanding of the dynamics of solar weather, problems of coronal heating, pre-flare and flare activities, and more.

The seven payloads are - Visible Emission Line Coronagraph (VELC), Solar Ultra-violet Imaging Telescope (SUIT), Solar Low Energy X-ray Spectrometer (SoLEXS), High Energy L1 Orbiting X-ray Spectrometer (HEL1OS), Aditya Solar wind Particle EXperiment (ASPEX), Plasma Analyser Package for Aditya (PAPA), and Magnetometer (MAG).
