ISRO Launches Key Defence Satellite, Private Sector Takes Centre Stage

Hyderabad: India’s trusted workhorse rocket, the Polar Satellite Launch Vehicle (PSLV), is set for a crucial return to flight after last year’s setback. On January 12, the Indian Space Research Organisation (ISRO) will launch its 64th PSLV mission, a moment seen as vital not only for restoring confidence in the launch vehicle but also for underscoring the rapid rise of India’s private space sector.

The mission, designated PSLV-C62 / EOS-N1, is scheduled to lift off from the Satish Dhawan Space Centre, Sriharikota, at 10.17 am. The rocket will carry 15 satellites, including a highly classified surveillance satellite named Anvesha, developed by the Defence Research and Development Organisation (DRDO). Equipped with advanced imaging capabilities, Anvesha is designed to significantly enhance India’s ability to monitor and map hostile positions with high precision.

While the defence payload forms the strategic core of the mission, PSLV-C62 is historic for another reason. For the first time, a single Indian private company — Hyderabad-based Dhruva Space — is contributing as many as seven satellites on one PSLV launch, marking a major milestone for India’s emerging private space ecosystem.

ISRO’s Vote of Confidence

ISRO Chairman Dr V Narayanan, described the mission as a reflection of both national capability and industry growth. “India’s workhorse rocket will show what ISRO can do for user agencies. The main passenger protects India from the skies, while the smaller co-passengers signify how India’s private space sector is flourishing, with one Hyderabad company, Dhruva Space, contributing seven satellites and setting a new benchmark,” he said. He added that the remaining eight co-passengers are also unique, including a re-entry module, and emphasised that the Department of Space is contributing to national growth while touching human lives.

Mission at a Glance

The primary payload, EOS-N1, is an Earth Observation satellite for a user agency, along with DRDO’s Anvesha surveillance satellite. The mission’s 15 co-passengers include seven satellites from Dhruva Space and eight others, featuring international payloads from France, Nepal, Brazil and the UK. A standout among them is KID (Kestrel Initial Technology Demonstrator), a prototype re-entry vehicle from a Spanish start-up that will splash down in the South Pacific Ocean after completing its mission.

PSLV-C62 is the ninth dedicated commercial mission undertaken by NewSpace India Limited (NSIL), ISRO’s commercial arm, and the 64th flight of the PSLV overall.

Why the Launch Matters

The previous PSLV mission in May 2025 ended in failure due to an anomaly in the rocket’s third stage, making this launch critical for restoring confidence in one of the world’s most reliable launch vehicles. Beyond the technical recovery, the mission also reflects a broader shift in India’s space programme, where private companies are no longer peripheral players but key partners.

Dhruva Space and the Private Sector Surge

Dhruva Space’s Director of Space Missions, Vishal Latha Balakumar, dismissed any concerns about flying on a PSLV soon after the earlier failure. “Absolutely not. PSLV has always been reliable and it stays to be. We are launching seven different satellites on a single mission right now,” he said.

The satellites include Thibolt-3, designed for connectivity and remote monitoring, as well as several student-built satellites developed in collaboration with institutions such as Dayanand Sagar University (Karnataka), CV Raman Global University (Odisha), and Assam Don Bosco University. Dhruva Space is also supplying deployers for all the missions and providing ground station services for select payloads.

Notably, the company has secured the first licence from IN-SPACe to offer “ground station as a service,” supporting missions such as AAYULSAT (OrbitAID) and MOI-1 (TM2 Space) for both domestic and international customers.

Strategic and Global Impact

At the heart of the mission is the Anvesha satellite, which will strengthen India’s surveillance and intelligence-gathering capabilities at a time of heightened geopolitical tensions. The presence of multiple international payloads further reinforces India’s status as a preferred and dependable launch destination, built on PSLV’s strong track record — including its 2017 world record of launching 104 satellites in a single mission.

Looking Ahead

Dhruva Space has ambitious plans beyond this launch, with work underway on larger satellite platforms ranging from 50 kg to over 100 kg, aligning with India’s vision of becoming a global hub for space technology and services.

A Defining Moment

The PSLV-C62 mission represents more than just another launch. It symbolises ISRO’s resilience, India’s strategic priorities, and the coming of age of the country’s private space industry. If successful, it could mark a turning point — deepening collaboration between ISRO and private players and positioning India as a formidable force in the global space economy.
