  • Indian Space Research Organization’s (ISRO) Polar Satellite Launch Vehicle (PSLV-C43) has successfully launched 31 satellites including HysiS on 29th November. 
  • It is the 45th flight of PSLV, and 13th core-alone flight (without boosters).
  • This mission consists of HysiS, 1 micro and 29 nano satellites;  combined weight of satellites is 641.5 kg.

Hyper Spectral Imaging Spectroscope (HysiS):

  • It is an earth observation satellite built around ISRO’S Mini Satellite 2 (IMS-2) bus weighing about 380 kg. The life of the observation satellite is five years.

  • The satellite will be put into a polar synchronous orbit, which sets it in motion along the axis that runs along the Earth’s geographic North and South Pole.
  • 30 Satellites are one each from Australia, Columbia, Canada, Finland, Malaysia, Netherland and Spain, and 23 from the USA.
  • India’s HysiS was launched at an altitude of 636 km while the foreign satellites were launched to an altitude of 504 km.
  • It is to study the earth’s surface in both the visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.

  • Data from the satellite will be used for various applications including agriculture, forestry, soil/geological, environments, coastal zones and inland waters etc.


  • Polar Satellite Launch Vehicle is a third generation launch vehicle of India. It is the first Indian launch vehicle to be equipped with liquid stages.
  • It consists of four stages, using solid and liquid propulsion systems alternately.

  • PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 45 consecutively successful missions by November 2018.
  • First PSLV was launched in October 1994. The vehicle successfully launched two spacecraft – Chandrayan-1 in 2008 and Mars Orbiter Spacecraft in 2013.
