Satish Dhawan Space Centre (SDSC): India’s Gateway to Space Exploration


The Satish Dhawan Space Centre (SDSC), formerly known as Sriharikota Range (SHAR), is India’s premier spaceport and a vital facility for the Indian Space Research Organisation (ISRO). Named in honor of Dr. Satish Dhawan, a prominent Indian space scientist and former chairman of ISRO, the center is located on Sriharikota Island in the southeastern state of Andhra Pradesh. Sriharikota Island is a spindle-shaped island in the SPSR Nellore district of Andhra Pradesh. It is situated in the backwater Pulicat Lake and sandwiched by Buckingham Canal on the West and the Bay of Bengal on the East. Established in 1971, the SDSC has played a pivotal role in advancing India’s space capabilities and is a testament to the nation’s remarkable progress in space exploration.

History and Evolution:

India’s journey into space exploration began in the early 1960s, and its ambitious space program required a dedicated launch facility. After an extensive search, Sriharikota Island was selected for its strategic location and proximity to the equator, which provides significant advantages for launching satellites into geostationary and polar orbits. The center was initially known as the Sriharikota Range (SHAR) and it became operational on October 9, 1971, with the flight of ‘Rohini-125’, a small sounding rocket.

On September 5, 2002, the center was renamed the Satish Dhawan Space Centre (SDSC) as a tribute to Dr. Satish Dhawan, who was instrumental in shaping India’s space program and steering it toward great success. Dr. Dhawan’s visionary leadership and scientific contributions significantly elevated India’s status in the global space community.

Infrastructure and Launch Vehicles:

SDSC boasts a state-of-the-art infrastructure with a range of launch pads and facilities. Notably, it features two operational launch pads: the First Launch Pad (FLP) and the Second Launch Pad (SLP). The First Launch Pad primarily handles the Polar Satellite Launch Vehicle (PSLV), used for launching a variety of payloads, including satellites for communication, remote sensing, and scientific research. The Second Launch Pad accommodates the larger and more powerful Geosynchronous Satellite Launch Vehicle (GSLV), designed to place heavier payloads into higher orbits.

Over the years, SDSC has witnessed numerous successful missions, including the prestigious Chandrayaan-1, India’s first lunar probe, and Mangalyaan (Mars Orbiter Mission), which made India the first Asian nation to reach Mars orbit and the fourth space agency in the world to do so.

Contributions to Space Research:

SDSC has been pivotal in advancing India’s space research endeavors. Its notable contributions include:

  1. Remote Sensing Satellites: SDSC has launched several remote sensing satellites, such as the Indian Remote Sensing (IRS) series, which have been instrumental in monitoring agricultural activities, disaster management, urban planning, and environmental conservation.
  2. Navigation Satellites: The center has played a key role in deploying the Indian Regional Navigation Satellite System (IRNSS), known as NavIC, which enhances navigation accuracy over the Indian subcontinent and the surrounding region.
  3. Interplanetary Missions: SDSC was at the forefront of India’s interplanetary missions with Chandrayaan-1 and Mangalyaan, which demonstrated India’s capabilities in exploring the Moon and Mars, respectively.
  4. International Collaboration: SDSC has collaborated with various international space agencies and organizations, strengthening India’s position in the global space community.

Future Endeavors

SDSC continues to evolve and expand its capabilities. It is set to be a crucial player in upcoming missions like Gaganyaan, India’s ambitious human spaceflight program, aimed at sending Indian astronauts (Gagannauts) to space. SDSC also plays a significant role in the development of the Unified Launch Vehicle (ULV) and reusable launch vehicle technology.
