ISRO successfully launches advanced earth observation satellite- HysIS

Indian Space Research Organisation (ISRO) has successfully launched country's first advance earth observation satellite- "Hyper Spectral Imaging Satellite (HysIS)", along with 30 other satellites from eight countries.

  • These satellites were launched on board of ISRO's workhorse PSLV-C43 from Satish Dhawan Space Centre (SDSC) at Sriharikota in Andhra Pradesh.

About the Mission:

  • PSLV-C43 was the 45th flight of Polar Satellite Launch Vehicle (PSLV) with a combined payload of 641.5kg.
  • It was the 'Core Alone' version of PSLV i.e. lightest version of the launch vehicle.
  • PSLV is a four stage launch vehicle with alternating solid and liquid stages.
  • HysIS, weighing around 380 kg was the primary payload of this PSLV-C43 mission.
  • The co-passengers of HysIS included 1 micro and 29 nano satellites from eight different countries including one each from Australia, Canada, Columbia, Finland, Malaysia, Netherlands, Spain and 23 from US.
  • All these satellites were commercially contracted for launch through ISRO's commercial arm Antrix Corporation Limited.
  • All these satellites were placed in a 504 km orbit.
  • The satellites were ejected in two orbits by restarting the rocket's fourth-stage engine twice.
  • PSLV had first released HysIS into orbit at 636 km, 17 minutes after launch.
  • Later,the engine of rocket's fourth stage was restarted to place the remaining satellites into desired orbits.

About the Hyper Spectral Imaging Satellite (HysIS):

  • It is India's first hyperspectral imaging satellite for advanced earth observation developed indigenously by ISRO.
  • It was placed in the 636 km-polar sun synchronous orbit with an inclination of 97.957 degree.
  • It has a mission life of five years.
  • Its primary goal is to study earth's surface in visible near infrared and shortwave infrared regions of electromagnetic spectrum within a bandwidth of 400nm-2500nm wavelength.
  • Optical imaging detector chip is the heart of this satellite which has been indigenously designed by Space Application Centre of ISRO and fabricated at its semi-conductor lab at Chandigarh.

Applications of HysIS:

  • The hyperspectral imaging satellite technology will be an added advantage in watching over India from space across sectors including defence, agriculture, land use and mineral exploration.
  • It will be primarily used in Agriculture, Forestry, Soil Survey, Geology, Coastal Zone Studies, Inland water Studies, Environmental monitoring and Pollution Detection from Industries.

What is Hyperspectral Imaging?

  • Hyperspectral imaging or hyspex imaging (imaging spectroscopy) combines the power of digital imaging and spectroscopy.
  • It collects and processes information from across electromagnetic spectrum.
  • Hyspex imaging enables distinct identification of objects, materials or processes on Earth by reading spectrum for each pixel of scene from space.
  • The hyspex technology is still an evolving science.
  • In recent times, it has become a trend that is being experimented globally.
  • It has the ability to add new dimension to plain-vanilla optical imagers.
