HysIS (Hyper Spectral Imaging Satellite) and PSLV
What is the News?
- India has successfully launched HysIS satellite. Nearly three minutes after lift-off, India’s workhorse launch vehicle, the PSLV, carrying 31 satellites on board soared in a trajectory crossing the path of the Sun and sped to inject India’s Hyper Spectral Imaging Satellite (HysIS), being dubbed ‘Sharp Eye’, towards the launcher’s intended first orbit.
- In its 13th flight of the core alone version and 45th launch of the PSLV, ISRO carried one satellite each from Australia, Canada, Colombia, Finland, Malaysia, Netherlands and Spain, and 23 satellites from the U.S. on board as co-passengers of the HysIS.
What is HysIS?
- Hyper Spectral Imaging Satellite (HysIS) is an Earth Observation satellite primarily to assist in a wide range of applications in agriculture, forestry, geological environments and coastal zones, among others.
- The data will also be accessible to India’s defence forces.
- HysIS will be able to monitor the Earth’s surface within a bandwidth of 400nm-2500nm wavelength.
- This include visible, near infrared and far infrared bands of the spectrum.
- HysIS satellite has been projected to a polar Sun synchronous orbit.
- With its orbit, it will remain at the same position relative to the Sun throughout its five-year mission, as it relays information about weather patterns, coastlines, atmospheric behaviour, and more.
PSLV (Polar Satellite Launch Vehicle)
- ISRO has successfully launched the PSLV-C43 mission that carried the HysIS satellite as part of its payload.
- Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO).
- It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits.
What is Sun-synchronous orbit?
- Sun-synchronous orbit is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet’s surface at the same local mean solar time.
Major payloads launched by PSLV are,
- India’s first lunar probe Chandrayaan-1
- India’s first interplanetary mission, Mars Orbiter Mission (Mangalyaan)
India’s first space observatory: Astrosat
