Satish Dhawan Space Centre (SHAR), Nellore: India’s Gateway to the Stars

Nestled on the serene island of Sriharikota in the Nellore district of Andhra Pradesh, the Satish Dhawan Space Centre (SDSC) SHAR stands as the primary spaceport of India.¹ Operated by the Indian Space Research Organisation (ISRO), SHAR has been the launchpad for numerous groundbreaking missions that have propelled India to the forefront of space exploration.² Its strategic location, coupled with world-class infrastructure, makes it an indispensable asset to the nation’s space program.

A Historical Perspective:

The Sriharikota Range (SHAR) was established in 1971 and was later renamed the Satish Dhawan Space Centre in 2002 in honor of the former Chairman of ISRO, Professor Satish Dhawan [1].³ The choice of Sriharikota was deliberate, primarily due to its eastern coastline location, which provides the advantage of eastward launches that can utilize the Earth’s rotation to gain additional velocity. Its relative isolation and low population density also ensure safety during launch operations.⁴

Key Infrastructure and Facilities:

SHAR boasts state-of-the-art infrastructure crucial for rocket assembly, integration, and launch.⁵ Some of the key facilities include:

• Launch Pads: SHAR has two operational launch pads that can support the launch of a variety of rockets, including the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) series [2].⁶
• Solid Propellant Space Booster Plant (SPROB): This facility manufactures and processes large solid rocket motors that power the initial stages of ISRO’s launch vehicles [3].⁷
• Static Test and Evaluation Complex (STEX): Here, rocket motors and stages undergo rigorous testing to ensure their reliability and performance before launch [4].
• Vehicle Assembly Building (VAB): This is where the different stages of a rocket are integrated and assembled before being moved to the launch pad [5].⁸
• Mission Control Center: From here, scientists and engineers monitor and control all aspects of a launch mission, from pre-launch checks to satellite deployment [6].

Significant Achievements:

SHAR has been the launch site for a multitude of significant missions that have marked milestones in India’s space journey.⁹ These include:

• Chandrayaan Missions: India’s first lunar missions, Chandrayaan-1 and Chandrayaan-2, were launched from SHAR, demonstrating India’s capability in lunar exploration [7].¹⁰
• Mangalyaan (Mars Orbiter Mission): This groundbreaking mission, which successfully placed an orbiter around Mars, was also launched from SHAR, making India the first Asian nation to reach Martian orbit [8].¹¹
• PSLV’s Remarkable Run: The Polar Satellite Launch Vehicle (PSLV), often referred to as ISRO’s workhorse, has had numerous successful launches from SHAR, deploying a wide array of Indian and foreign satellites into various orbits [9].¹²
• GSLV and GSLV Mk III Missions: SHAR has also been the launch site for the Geosynchronous Satellite Launch Vehicle (GSLV) and its more powerful variant, the GSLV Mk III, which are crucial for deploying heavier communication satellites [10].¹³

Impact on Nellore and Beyond:

The presence of SHAR has had a significant impact on the Nellore region. It has created numerous employment opportunities, both directly within ISRO and in ancillary industries. The center has also fostered educational and research activities in the area. Furthermore, the achievements of ISRO, with SHAR at its forefront, have brought national pride and inspired generations of scientists and engineers across India.

Looking Ahead:

SHAR continues to play a vital role in India’s ambitious space program. With plans for future missions, including Gaganyaan (India’s first human spaceflight program) and further interplanetary explorations, the Satish Dhawan Space Centre remains the crucial gateway through which India will reach for the stars.¹⁴
