Recently, the Solar Ultraviolet Imaging Telescope (SUIT), a unique space telescope developed by Pune’s Inter-University Center for Astronomy and Astrophysics (IUCAA) has been delivered to the Indian Space Research Organisation (ISRO).

About Solar Ultraviolet Imaging Telescope (SUIT)

  • The telescope is one of the seven payloads on Aditya-L1.
  • Features
    • It is unique because it will provide full disk images of the sun in 2000 to 4000 A wavelength range which has never been obtained.
    • It will allow us to record images in this wavelength crucial for maintaining the Ozone and Oxygen content in the atmosphere of the Earth.
    • It will also measure the UV radiation hazardous for skin cancer.
    • It will address fundamental questions such as the existence of a higher-temperature atmosphere above the cooler surface of the Sun and the origin and variation of near-ultraviolet radiation and high-energy solar flares.
    • It will help in the measurement of solar radiation from Hard X-ray to Infrared, as well as in-situ measurements of particles in the solar wind, including the Sun’s magnetic field at the L1 point.
  • It is expected to last five years.
  • Funding: ISRO funded the initial Rs 25 crore required for the hardware, a small portion of the overall project.

Key points about Aditya-L1 Mission

  • It is India’s first dedicated scientific mission to study the Sun.
  • The spacecraft will be placed in a halo orbit around the first Lagrange point, L1, which is 1.5 million km from the Earth towards the Sun.
  • A satellite around the L1 point has the major advantage of continuously viewing the Sun without occultation/eclipses.
  • Aditya-L1 carries seven payloads to observe the photosphere, chromosphere, and the outermost layers of the Sun (the corona) using electromagnetic and particle detectors.
  • The satellite will be launched by a PSLV-XL launch vehicle from Sriharikota
