Vikram Sarabhai Space Centre

What Vikram Sarabhai Space Centre does

Vikram Sarabhai Space Centre (VSSC) is the lead launch vehicle research and development centre of the Indian Space Research Organisation (ISRO), operating under India's Department of Space. Founded in 1962 at Thumba, Kerala, near the magnetic equator, VSSC designs, develops and integrates India's full portfolio of launch vehicles — the Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV), heavy-lift LVM3 (GSLV Mk III), Rohini sounding rockets, and the new Small Satellite Launch Vehicle (SSLV). Advanced programmes in development include the Reusable Launch Vehicle (RLV), Air Breathing Propulsion hypersonic technology, and the Gaganyaan human-rated launch system targeting India's first crewed spaceflight by early 2027.

VSSC's technology stack spans solid propulsion, cryogenic systems, aero structures, composites, avionics, guidance and control, aerospace mechanisms, vehicle integration and testing, and space ordnance. Its Space Physics Laboratory (SPL) operates the ARFINET aerosol monitoring network of 42+ observatories across India including Arctic and Antarctic stations, and conducts atmospheric and climate research. Supporting units include the Ammunition Perchlorate Experimental Plant (APEP) at Aluva for solid propellant production, the ISRO Inertial Systems Unit (IISU) for inertial systems, and the Semi-Conductor Laboratory (SCL) at Chandigarh for ASIC and MEMS development.

The centre is funded primarily through Department of Space budget allocations from the Government of India, which also acts as its principal customer for satellite deployment, navigation, Earth observation and scientific missions. Commercial launch services are channelled through Antrix Corporation Limited, DOS's commercial arm, executing dedicated missions such as OneWeb India-1 and BlueBird Block-2. VSSC leads a network of 18 ISRO centres across India, enabling end-to-end programme ownership from propulsion development to launch operations at Sriharikota, and serves international collaborators including NASA through joint missions to the International Space Station.

Broad incumbents

• China Aerospace Science and Technology Corporation (CASC): CASC operates the full Long March launch family (CZ-2 through CZ-7) and is the principal Chinese state-owned launch vehicle prime — comparable to VSSC as a state-owned launch vehicle developer with parallel indigenous propulsion, cryogenic, and crewed spaceflight programs.
• Northrop Grumman: Northrop Grumman produces solid rocket motors (Omegas, SRB-X) and operates the Antares launch vehicle for Cygnus missions. It is comparable to VSSC as a propulsion and launch systems integrator for national security and commercial customers.
• Japan Aerospace Exploration Agency (JAXA): JAXA operates Japan's H3 and Epsilon launch vehicles and pursues crewed launch ambitions. It is comparable to VSSC as a national space agency developing indigenous launch vehicles and advanced propulsion (including reusable and reusable cryogenic capabilities).

Emerging players

• Relativity Space: Relativity is developing Terran R, a reusable medium-to-heavy lift launch vehicle using additive manufacturing. It overlaps partially with VSSC's RLV and LVM3 programs, especially around next-generation manufacturing techniques and reusable heavy-lift operations.
• Skyroot Aerospace: Skyroot Aerospace is an Indian private launch vehicle startup developing the Vikram-II series small launchers — emerging domestic competition relevant to VSSC's SSLV in the Indian small-satellite launch market.
