ISRO’s PSLV-C43 successfully launched earth observation satellite HysIS and 30 foreign satellites from Satish Dhawan Space Centre (SDSC) in Sriharikota.

Hyper-Spectral Imaging Satellite (HysIS):

  • Features: HysIS is an earth observation satellite built around ISRO’s Mini Satellite2 (IMS-2) bus weighing about 380kg. it has been indigenously designed and built.

  • Objective: The primary goal of HysIS is to capture High Definition images of Earth's surface i.e. to study the earth’s surface in both the visible, near infrared and shortwave infrared regions of the electromagnetic spectrum.

  • Application: Data from the satellite will be used for a wide range of applications including agriculture, forestry, soil/geological environments, coastal zones and inland waters, etc.

  • Mission Life: The mission life of the satellite is five years.

  • Significance: Globally, only a few nations have their operational satellites of its class, that can capture crystal clear images of the earth's surface for varied applications.

30 foreign satellites:

  • Alongwith HysIS, PSLV-C43 also launched one micro and 29 nano-satellites from 8 countries, including Australia, Canada, Columbia, Finland, Malaysia, Netherlands, Spain and USA.

  • These foreign satellites launched are part of commercial arrangements between Antrix Corporation Limited and customers.

Polar Satellite Launch Vehicle (PSLV):

  • PSLV is a four stage launch vehicle with a large solid rocket motor forming the first stage, an earth storable liquid stage as the second stage, a high performance solid rocket motor as third stage and a liquid stage with engines as fourth stage.

  • This was the 45th flight of PSLV and 13th one in the Core Alone configuration. So far, the PSLV has launched 44 Indian and nine satellites built by students from Indian universities. The vehicle has also launched 269 international customer satellites.
