Solar Ultraviolet Imaging Telescope

What’s the News?

The Solar Ultraviolet Imaging Telescope(SUIT) has been delivered to the Indian Space Research Organisation (ISRO).

What is the Solar Ultraviolet Imaging Telescope (SUIT)?

  • The Solar Ultraviolet Imaging Telescope is a unique space telescope developed by Pune’s Inter-University Center for Astronomy and Astrophysics (IUCAA).
  • The Solar Ultraviolet Imaging Telescope will be integrated with the ADITYA-L1 mission expected to be launched in mid-August,2023.
  • It aims to study the Sun’s ultraviolet (UV) emissions and capture , known as the high-resolution images of the Sun’s atmospherecorona, in various UV wavelengths.
  • It has an off-axis Ritchey-Chrétien configuration with a which will combination of 11 narrow and broad bandpass filters be used for full-disk solar imaging in the Ultraviolet (UV) wavelength range 200-400 nm.


  • The SUIT telescope will address fundamental questions such as the existence of a higher-temperature atmosphere above the cooler surface of the Sun ultraviolet radiation and high-energy solar flares.
  • It will allow us to record images in this wavelength crucial for in the atmosphere of maintaining the Ozone and Oxygen content the Earth.
  • It will also measure the UV radiation hazardous for skin cancer.
  • It will help in the measurement of solar radiation from Hard X-ray to Infrared, as well as in in-situ measurements of particles in the solar wind, including the Sun’s magnetic field at the L1 point

Points about Aditya-L1 Mission

  • It is the first dedicated solar mission of the Indian Space (ISRO), which will be put in a halo orbit at Research Organizationthe Sun-Earth Langrage point (L1).
  • The mission is expected to be launched using a Polar Satellite Launch Vehicle (PSLV) rocket.
  • ISRO’s first space observatory dedicated to aims studying the Sunto provide regular images and updates on the Sun’s surface phenomena and space weather.
  • The Aditya-L1 mission will capable carry seven different payloads of studying various phenomena on the Sun across the electromagnetic spectrum and solar wind.
