Introduction to ISRO and Its Launch Capabilities
The Indian Space Research Organisation (ISRO) is India’s leading space agency, and is recognized internationally for its more affordable and novel space missions. ISRO has explored the solar system with the Mars Orbiter Missions and intends to send future missions to the Moon and beyond. ISRO has placed a range of satellites in space to meet India’s needs for earth observation, navigation, and communications, and will continue to develop the frontier of space for India.
In 2025, ISRO achieved another mission in its growing timeline with the PSLV C61 EOS-09 mission, while the PSLV continued to demonstrate ISRO’s leadership role in space research and technology.
Overview of the PSLV Launch Vehicle
ISRO’s most reliable launch vehicle is the Polar Satellite Launch Vehicle (PSLV). PSLV is quite versatile, and launched over 50 Indian and foreign satellites.
PSLV Full Form: Polar Satellite Launch Vehicle
Key Features:
- Four-stage rocket
- Capable of carrying satellites into Sun-synchronous and geosynchronous orbits
- Proven reliability with over 90% success rate
The PSLV has been used in historic missions like Chandrayaan-1, Mangalyaan, and numerous satellite deployments for other countries.
What is EOS-09?
EOS-09 (Earth Observation Satellite-09) is part of India’s growing earth observation satellite series designed to support agricultural planning, urban development, disaster management, and environmental monitoring.
EOS Series Objective:
To provide high-resolution imagery for weather forecasting, crop monitoring, and earth science studies.
EOS-09 Features:
- Advanced optical remote sensing payload
- Multi-spectral imaging capability
- High revisit frequency
EOS-09 enhances ISRO’s ability to monitor terrestrial changes, helping governments make data-driven decisions.
