India’s space agency, ISRO, is all set to mark a significant milestone with the 101st flight of its trusted Polar Satellite Launch Vehicle (PSLV). Scheduled for early morning on May 18, 2025, the PSLV-C61 mission will deploy the advanced Earth observation satellite EOS-09 from the Satish Dhawan Space Centre, Sriharikota. This launch underscores India’s growing prowess in space technology and its strategic focus on national security and development.
PSLV-C61: The Workhorse of India’s Space Missions
The PSLV has been the backbone of ISRO’s satellite launches since its inception, known for its reliability and versatility. The upcoming PSLV-C61 mission continues this legacy, carrying one of the heaviest Earth observation satellites, EOS-09, weighing approximately 1700 kg. This mission marks a critical step in enhancing India’s space capabilities with high-resolution, all-weather imaging technology.
Launch Details at a Glance
Date & Time: May 18, 2025, 5:59 AM IST
Launch Site: Satish Dhawan Space Centre, Sriharikota
Payload: EOS-09 Earth Observation Satellite
Mission: All-weather, high-resolution Earth imaging for Indian applications
EOS-09: A Game-Changer in Earth Observation
EOS-09, also known as Earth Observatory Satellite-09, is designed to provide high-quality images regardless of weather conditions, day or night. Its advanced sensors will play a vital role across multiple sectors:
Agriculture: Monitoring crop health, soil moisture, and irrigation efficiency
Disaster Management: Early detection and assessment of floods, cyclones, and other natural calamities
Urban Planning: Assisting in infrastructure development and land-use mapping
National Security: Enhancing surveillance and reconnaissance, especially along sensitive border areas
ISRO Chairman V. Narayanan emphasized the satellite’s exclusive focus on Indian applications, highlighting its strategic importance in safeguarding the nation and supporting governance.
Strategic Timing Amid Geopolitical Challenges
The launch of EOS-09 comes at a crucial time when India is focusing on strengthening its surveillance capabilities in the wake of recent security challenges, including the Pahalgam terror attack and Operation Sindoor. Former ISRO scientist Manish Purohit noted that EOS-09 is a follow-up to the RISAT-1 mission, enhancing India’s ability to monitor borders and coastal regions with greater precision.
“This launch is strategically timed. It strengthens monitoring at borders and coasts, particularly in sensitive areas. The satellite can detect ingress or suspicious movements, which is vital for anti-terror operations,” said Purohit.
Preparations and Live Coverage
ISRO has completed all pre-launch activities, including moving payloads from the integration facility to the mobile service tower. The launch will be broadcast live from 5:29 AM IST on May 18, allowing enthusiasts and citizens to witness this landmark event.
ISRO’s Commitment to Technological Excellence and National Interest
With the PSLV-C61/EOS-09 mission, ISRO continues to demonstrate its dual commitment to advancing space technology and serving India’s national interests. The satellite’s capabilities will bolster India’s self-reliance in space-based intelligence and resource management.
ISRO’s achievements not only enhance India’s stature globally but also provide critical tools for sustainable development and security at home.
Conclusion: A Proud Moment for India’s Space Journey
The upcoming PSLV-C61 launch is more than just another mission; it is a symbol of India’s technological progress and strategic foresight. As EOS-09 takes its place in orbit, it will empower India with enhanced Earth imaging capabilities, supporting agriculture, disaster response, urban growth, and defense.
This launch reinforces ISRO’s role as a key player in the global space arena and a vital contributor to India’s national security and development goals.
