Overview

Sriharikota is a narrow barrier island off the coast of the southern Indian state of Andhra Pradesh. The island is best known as the location of the Satish Dhawan Space Centre (also called SHAR), which serves as the primary launch complex for India’s orbital rockets. Its coastal position between a major lagoon and the open sea has shaped both its human use and its natural environment.

Geography and environment

Sriharikota separates the brackish waters of Pulicat Lake from the Bay of Bengal and forms part of a dynamic coastal system. The island’s dune, marsh and scrub habitats support migratory birds and coastal wildlife around Pulicat, while its sandy shoreline faces the open ocean. The inhabited settlement nearest the island is the historic town of Pulicat, and administrative jurisdiction places the area in the Potti Sri Ramulu Nellore district. Transport connections link Sriharikota to nearby towns such as Sullurpeta and the industrial township Sri City.

Spaceport and facilities

The island hosts the Satish Dhawan Space Centre, operated by the Indian Space Research Organisation (ISRO). Launch pads, vehicle assembly buildings, control centres and tracking infrastructure are located here to support orbital missions. Sriharikota is used to launch satellites (satellite) into polar and geostationary transfer orbits using multi-stage launchers. Commonly used vehicles include the Polar Satellite Launch Vehicle and the Geosynchronous Satellite Launch Vehicle, examples of indigenous Indian rocket technology (launch vehicles).

History and development

Selected for its long, sparsely populated coastline and clear sea-track range, Sriharikota was developed to concentrate launch operations away from populated centres. Over time the site expanded with additional pads and support facilities to meet growing launch cadence. Its proximity to the sea allows safe downrange trajectories for polar and eastward launches, while access routes connect the complex to urban centres such as Chennai and regional transport hubs.

Access, logistics and local context

The nearest railway and highway connections are at Sullurpeta, which provides a gateway for personnel and supplies. The island itself is reached by a causeway and controlled entry because of the sensitive nature of launch operations. Sriharikota’s position adjacent to Pulicat Lake means local livelihoods, tourism and fishing interact with the spaceport’s activities, requiring coordinated environmental and social planning.

Significance and notable facts

Sriharikota is India’s principal orbital launch facility and a focal point for the nation’s civil space programme. Its geography — a barrier island between Pulicat Lake and the Bay of Bengal — provides a natural corridor for launches, while proximity to coastal communities shapes the site’s environmental stewardship.
