  • 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.

PSLV:

  • 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.
