ISRO to launch new imaging satellite HysIS on Thursday

News:

  1. ISRO’s workhorse rocket PSLV-C43 will carry India’s earth observation satellite HysIS and 30 co-passenger satellites, including 23 from the US, from Sriharikota on November 29.

Important Facts:

  1. About the launch:
  • HysIS, the country’s first hyperspectral imaging satellite for advanced Earth observation will be launched from Sriharikota.
  • It is the primary satellite of the PSLV-C43 mission.
  • The satellite will be placed in 636 km polar sun synchronous orbit (SSO) with mission life of five years.
  • The co-passengers of HysIS include one micro and 29 nano satellites from eight different countries, the agency said, adding, all these satellites will be placed in a 504 km orbit by PSLV-C43.
  • The countries comprise United States of America (23 satellites), Australia, Canada, Columbia, Finland, Malaysia, Netherlands and Spain (one satellite each).
  • HysIS will be the third longest mission of PSLV.
  • The longest mission, C-40 in 2018, lasted two hours and 21 minutes and put 31 satellites to orbit.
  • In September 2016 and C-35 lifted eight satellites in a flight lasting two hours and 15 minutes.
  1. Significance of the launch:
  • The technology will be an added advantage of watching over India from space for a variety of purposes such as defence, agriculture, land use, minerals and so on.
  • It can also be highly useful in marking out a suspect object or person and separate it from the background which could aid in detecting transborder or other stealthy movements.
  1. About hyperspectral imaging camera (HysIS)
  • The primary goal of HysIS is to study the Earth’s surface in visible, near-infrared and shortwave infrared regions of the electromagnetic spectrum.
  • HysIs in space can provide well-defined images that can help to identify objects on Earth far more clearly than regular optical or remote sensing cameras.
  1. Background:
  • In 2008, a small 83-kg demonstration microsatellite called IMS-1 (Indian Mini Satellite-1) was launched as a secondary passenger with Cartosat-2A.
  • In the same year, it put a HysSI or Hyperspectral Imager on the first lunar mission Chandrayaan-1 and used it to scan Moon’s surface for minerals.
  1. About PSLV:
  • PSLV is ISRO’s third generation launch vehicle and is a four-stage launch vehicle with alternating solid and liquid stages and engines.
  • It can carry upto 1,750 kg of payload into polar SSO of 600 km altitude.
  • Additionally, PSLV has been used to launch planetary missions and also satellites into Geosynchronous Transfer Orbit.
