India Set to Launch 101st Rocket: EOS-09 Spy Satellite (PSLV-C61) Lifts Off on May 18

India Set to Launch 101st Rocket- The EOS-09 Spy Satellite is scheduled to launch on the Polar Satellite Launch Vehicle (PSLV- C61) from the Satish Dhawan Space Centre in Sriharikota on May 18, 2025, marking India’s 101st rocket launch. This mission marks another milestone for the Indian Space Research Organisation (ISRO), reinforcing India’s growing capabilities in Earth observation, national security, and disaster management.

What is EOS-09?

EOS-09, also known as RISAT-1B, is an advanced Earth observation satellite equipped with a C-band synthetic aperture radar (SAR). This cutting-edge technology enables the satellite to:

• Capture high-resolution images of the Earth’s surface.
• Operate day and night, regardless of weather conditions.
• Provide critical intelligence for border surveillance, disaster monitoring, and urban planning.

The satellite will be placed in a sun-synchronous orbit, ensuring consistent lighting for its imaging tasks.

PSLV- C61: India’s Trusted Workhorse

The PSLV-C61 mission is the 27th launch of the PSLV-XL variant and the 63rd flight of the Polar Satellite Launch Vehicle (PSLV). Known for its reliability and versatility, PSLV has been instrumental in launching remote sensing, navigation, and interplanetary missions.

Key Features of PSLV-C61

• Four-stage rocket with six solid strap-on boosters.
• Orbit Change Thrusters (OCT) for post-mission disposal.
• Deorbiting fuel for responsible space operations.

Strategic Importance of EOS-09

EOS-09 is expected to play a crucial role in national security, particularly in border surveillance along India’s frontiers with Pakistan and China. The satellite’s five imaging modes allow it to:

• Detect suspicious movements in sensitive areas.
• Monitor coastal activities for maritime security.
• Support anti-terror operations with real-time intelligence.

EOS-09 is a strategic successor to the RISAT-1 mission, strengthening India’s surveillance capabilities, stressed former ISRO scientist Manish Purohit.

Conclusion – India Set to Launch 101st Rocket

The EOS-09 Spy Satellite launch marks another major achievement for ISRO, reinforcing India’s space-based surveillance and disaster management capabilities. As PSLV-C61 lifts off on May 18, the mission will further strengthen India’s position in global space technology and national security preparedness
