India is preparing for a significant expansion of its space-launch infrastructure, with the country targeting four functional launch pads by 2029, according to ISRO Chairman V. Narayanan.
The roadmap comes as satellite deployment requirements increase and India seeks to strengthen its ability to support domestic space programmes and commercial launch activity. The expansion is expected to combine new launch infrastructure with greater participation from private companies and startups.
Editorial Insight
Key Highlights
Important points readers should notice.
Issue/Event: Expansion of India's space-launch infrastructure
Location: Sriharikota and Kulasekarapattinam, Tamil Nadu
Authority/Organisation: ISRO
Action Taken: Four functional launch pads targeted by 2029; upcoming uncrewed Gaganyaan tests outlined
Impact: Potential increase in launch capacity, mission readiness and opportunities for the domestic space industry
Narayanan outlined the plans while addressing a university convocation near Chennai. The proposed infrastructure includes a dedicated Small Satellite Launch Vehicle complex at Kulasekarapattinam in Tamil Nadu and a third launch pad at Sriharikota.
The planned Kulasekarapattinam complex is expected to cover approximately 2,000 acres. Its proposed infrastructure includes launch facilities, integration buildings, tracking systems and supporting technical facilities.
The expansion is intended to improve India's capacity to accommodate different launch requirements. However, the 2029 target is a stated plan, not confirmation that all four launch pads are already operational or that every facility will necessarily be completed on schedule.
Editorial Analysis
Why This Matters
Additional launch infrastructure could improve India's ability to support satellite missions and future space programmes. The Gaganyaan testing roadmap is equally important because human spaceflight requires extensive validation of spacecraft safety and life-support systems. The practical impact will depend on implementation, testing results, infrastructure completion and the pace of commercial demand.
Gaganyaan testing remains a major priority
Alongside launch infrastructure, ISRO is progressing towards the next stages of Gaganyaan, India's human-spaceflight programme.
Narayanan said the first uncrewed test was planned within the following two months, with two additional uncrewed tests expected before the crewed mission.
These tests are intended to evaluate important systems and operating conditions before astronauts travel aboard the spacecraft. Areas of assessment include environmental control, safety systems, crew-escape mechanisms and module performance under varying pressure, temperature and humidity conditions.
The uncrewed missions are important because they allow engineers to assess spacecraft performance without placing astronauts aboard. The results can help identify technical issues and guide any required modifications before a crewed flight is attempted.
The ISRO chairman also said that approximately 8,000 ground-based experiments had been conducted for the Gaganyaan programme. Four astronaut-designates were undergoing specialised training, according to his remarks.
Private-sector participation and future missions
The planned expansion also reflects the growing role of private industry in India's space ecosystem. ISRO intends to support startups and private enterprises by facilitating technological development and participation in space-related activities.
Private-sector involvement does not mean that ISRO is being privatised. Narayanan clarified that the national space agency would continue its role while working with industry to address increasing launch demand.
He also outlined plans for Chandrayaan-5, a proposed collaborative lunar mission with Japan's space agency. The mission plan discussed included a rover weighing approximately 350 kilograms, designed to conduct surface experiments over 100 days.
The details remain subject to the relevant programme approvals, technical planning and future official updates.
