ISRO to Launch Earth Observation Satellite HysIS Aboard PSLV-CA Rocket on November 29

In a significant development, the Indian Space Research Organisation (ISRO) announced that it will be launching its earth observation satellite, HysIS, along with 30 other small satellites from eight countries, on Thursday, November 29. The Polar Satellite Launch Vehicle Core Alone variant (PSLV-CA) will carry the 380 kg Hyper Spectral Imaging Satellite (HysIS) and the 30 additional satellites, which together weigh 261.5 kg.

The PSLV rocket is a four-stage launch vehicle that uses alternating solid and liquid stages and engines. The mission will be completed in just 112 minutes after the liftoff, with the rocket’s fourth stage being switched off in just over 16 minutes. The HysIS satellite will be placed in a 636 km polar sun-synchronous orbit, 17 minutes into the flight. Post-ejection of HysIS, the fourth stage will be restarted and used to place the remaining 30 small satellites in a 504 km orbit.

The primary goal of HysIS is to study the earth’s surface in visible, near infrared and shortwave infrared regions of the electromagnetic spectrum. The satellite has a mission lifespan of five years. The 30 small satellites, which have been commercially contracted for launch through Antrix Corporation Limited, the commercial arm of ISRO, include 23 from the US and one each from Australia, Canada, Columbia, Finland, Malaysia, the Netherlands, and Spain.

This launch marks ISRO’s continued efforts to enhance its capabilities in earth observation and remote sensing. The agency has been actively working to expand its fleet of satellites for geo-intelligence gathering and has plans to launch 50 satellites over the next five years to support this capability. ISRO chairman S Somanath recently stated that for India to become a strong nation, it is necessary to improve the ability of satellites to detect changes, bring in more AI-related and data-driven approaches to analyze data, and reduce data downloads.

The launch of HysIS and the 30 small satellites is a significant milestone for ISRO and demonstrates its commitment to advancing space technology and earth observation capabilities. The mission is expected to yield valuable data and contribute to a better understanding of the earth’s surface and its various processes. – The Blaze Times
