TL;DR: ISRO four launch pads 2029 explained in one line: ISRO chairman V Narayanan has said India will have four functional launch pads by 2029 — the two existing pads at Sriharikota, a third pad there, and a new small-satellite spaceport at Kulasekarapattinam — while the first uncrewed Gaganyaan test flies within two months.

📌 KEY HIGHLIGHTS

  • ISRO will have four operational launch pads by 2029, chairman V Narayanan said on Saturday, 24 October 2026, at a graduation ceremony in Chennai.
  • The four pads are: the two existing pads at Sriharikota, a third pad being built there, and the new SSLV launch complex at Kulasekarapattinam in Tamil Nadu.
  • The 2,000-acre Kulasekarapattinam spaceport will be dedicated to Small Satellite Launch Vehicle (SSLV) flights, with its first launch expected next year.
  • Private companies will help run operations at the new spaceport — but ISRO will not be privatised, Narayanan stressed.
  • The first uncrewed Gaganyaan test is due within two months, with three uncrewed flights in total before Indian astronauts fly.

ISRO four launch pads 2029 explained: what Narayanan announced

Speaking as chief guest at the graduation ceremony of the Sri Ramachandra Institute of Higher Education and Research in Chennai, ISRO chairman and Department of Space secretary V Narayanan laid out the agency's launchpad roadmap. "India will expand its space operations significantly with four functional launch pads by 2029," he said, adding that the expansion is backed by "an increasing reliance on private industry partnerships to handle commercial operations".

The plan addresses a bottleneck. India currently launches from two pads at the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh, and demand for launches — from Indian satellites, private startups and foreign customers — is outgrowing that capacity. The four-pad network spreads the load across two states and two vehicle classes:

Launch padLocationStatus and role
First Launch Pad (FLP)SriharikotaOperational — PSLV and GSLV flights
Second Launch Pad (SLP)SriharikotaOperational — universal pad for ISRO's fleet
Third Launch Pad (TLP)SriharikotaApproved by the Union Cabinet in January 2025 — will support heavier future rockets including the Next Generation Launch Vehicle
SSLV launch complexKulasekarapattinam, Tuticorin district, Tamil NaduUnder development on 2,000 acres — dedicated small-satellite launches; first flight expected in 2027

What Kulasekarapattinam adds — and why private firms are involved

The Kulasekarapattinam complex is purpose-built for the SSLV, ISRO's small-lift rocket aimed at the booming market for small satellites. It will include stage-preparation and vehicle-integration buildings, a launch pad, rail-track systems, range systems, checkout systems, telemetry and telecommand systems, and safety and firefighting facilities. Its coastal site in southern Tamil Nadu suits launches toward polar orbits, and a dedicated small-satellite pad frees Sriharikota's pads for bigger PSLV and GSLV missions.

Narayanan was explicit about the private-sector role — and its limits. Clarifying that ISRO will not be privatised, he said partnering with private firms is essential because of surging demand for thousands of satellites. "To handle this expanding ecosystem, ISRO will handhold startups and private enterprises, transferring technological expertise to foster economic growth and generate thousands of high-tech jobs," he said. Private companies will be brought into some operations at Kulasekarapattinam, a model that mirrors how India's space sector has opened up since 2020, with startups now building rockets and satellites of their own.

Why it matters for India readers

The pad announcement came with a human-spaceflight update that matters just as much. Narayanan said ISRO plans to conduct the first uncrewed Gaganyaan test within the next two months, followed by two more uncrewed tests before the crewed mission. The tests will check the crew escape system, environmental control and safety systems — including pressure, temperature, humidity and oxygen and carbon dioxide levels inside the crew module — and the systems that slow the module down for a safe return. Around 8,000 ground-based experiments for the mission are already done, and four astronaut-designates are in specialised training.

Looking further ahead, Narayanan confirmed plans for Chandrayaan-5, a joint lunar mission with Japan's space agency JAXA, featuring a 350-kg rover designed to run 100 days of experiments on the Moon's surface. For Indian readers, the thread connecting all three announcements is capacity: more pads mean more flights, more flights mean faster missions, and a private-sector pipeline means more engineering jobs beyond ISRO itself. The contrast with the United States is instructive — California's Vandenberg base alone flew its 71st launch of 2026 this week, as covered in SpaceX's record-tying Falcon 9 flight — while India is still building toward that kind of launch cadence.

Should you care?

✅ Verdict: If you follow India's space programme, this roadmap is worth tracking — not because a 2029 target is guaranteed, but because it sets the next three milestones in plain sight: the first Kulasekarapattinam launch in 2027, the first uncrewed Gaganyaan test within two months, and the third Sriharikota pad. Watch those three dates, not the headline number, to judge whether the plan is on track.

What to watch next

Three things will decide how this story reads a year from now: whether the first uncrewed Gaganyaan test flies on the promised two-month timeline; whether Kulasekarapattinam hosts its first SSLV launch in 2027 as planned; and how the private-operator arrangements at the new spaceport are structured. ISRO's next big launch milestone is closer still — the NVS-03 navigation satellite launch on 30 October from Sriharikota.

FAQs

When will ISRO have four launch pads?
ISRO chairman V Narayanan has said India will have four functional launch pads by 2029: the two existing pads at Sriharikota, a third pad being built there, and the new SSLV launch complex at Kulasekarapattinam in Tamil Nadu.

Where is the Kulasekarapattinam spaceport?
Kulasekarapattinam is in Tuticorin district of Tamil Nadu. The 2,000-acre complex is dedicated to Small Satellite Launch Vehicle (SSLV) launches, with integration buildings, a launch pad, rail-track systems, telemetry and tracking systems, and its first launch expected in 2027.

When is the first uncrewed Gaganyaan test?
Within the next two months from 24 October 2026, according to Narayanan. Three uncrewed tests in total will fly before the crewed Gaganyaan mission, testing the crew escape system, environmental control, safety systems and the crew module's interiors.

What is Chandrayaan-5?
Chandrayaan-5 is a planned joint lunar mission between ISRO and Japan's space agency JAXA, featuring a 350-kg rover designed to conduct 100 days of experiments on the Moon's surface.

Takeaway: Four pads by 2029, a small-satellite spaceport in Tamil Nadu, Gaganyaan's uncrewed tests within two months and Chandrayaan-5 on the horizon — India's space programme is building the launch capacity its ambitions need.
