Aditya-L1 mission updates: SUIT payload captures full-disk images of the Sun

Here, you will get all the updates about India’s first solar mission Aditya-L1:

December 8: SUIT payload captures full-disk images of the Sun

Aditya-L1’s onboard SUIT payload (instrument) captured the first full-disk images of the sun in near ultraviolet wavelengths (200–400 nm) on December 6, 2023, and the Indian Space Agency, ISRO, released these images on December 8, 2023.

SUIT stands for Solar Ultra-violet Imaging Telescope. SUIT captures images of the Sun’s photosphere and chromosphere in near ultraviolet wavelengths (200–400 nm) using various scientific filters.

The above image revealed notable features like sunspots, plages, and quiet sun regions at 280 nm wavelength. 

SUIT observations will help scientists study the dynamic coupling of the magnetized solar atmosphere and assist them in placing tight constraints on the effects of solar radiation on Earth’s climate.

The SUIT instrument is developed by Inter University Centre for Astronomy and Astrophysics (IUCAA), Pune in close collaboration with ISRO.

Aditya-L1 mission

Aditya-L1 is the first Indian space mission to study the sun from L1 in space. In Sanskrit, Aditya means the Sun. L1 is the Lagrange Point 1 of the Sun-Earth system, which is located about 1.5 million kilometers from the Earth in space.

In simple words, Lagrange Point 1 (L1) of the Sun-Earth system is a region in space where the gravitational forces of the Sun and Earth create an equilibrium. It is also called the parking spot in space. Please remember there are five Lagrange Points (L1, L2, L3, L4 and L5) of the Sun-Earth system.

Aditya-L1 spacecraft carries total seven payloads (instruments) to observe the photosphere, chromosphere, and the outermost layers of the Sun (the corona).

Scientific payloads (instruments) of Aditya-L1:

Aditya-L1 carries seven scientific payloads to study the sun from space. All payloads are indigenously developed in close collaboration with ISRO.
