The Indian Space Research Organisation (ISRO) has successfully launched its Small Satellite Launch Vehicle (SSLV), marking a significant milestone in India's space exploration efforts. This launch carried the experimental earth imaging satellite EOS-8 and the SR-0 Demo Sat, developed by the Chennai-based start-up Space Rickshaw. The SSLV, a compact rocket weighing 120 tonnes, is engineered to deploy satellites weighing up to 500 kilograms into low Earth orbit. For comparison, India's largest rocket, the Geosynchronous Satellite Launch Vehicle (GSLV Mk 3), also known as Bahubali, has a heftier weight of 640 tonnes.
In line with ISRO's strategy to execute cost-efficient space missions, the SSLV was developed with an investment exceeding ₹170 crore, a project that spanned over seven years. While ISRO has not publicly disclosed the precise cost of the launch, industry analysts suggest that each SSLV mission will cost around ₹30-35 crore, positioning it as one of the most economical launch vehicles in its class.
The EOS-8 satellite is equipped with a specialized instrument designed to measure ultraviolet (UV) light exposure on surfaces. This technology is set to play a crucial role in India's inaugural manned space mission, Gaganyaan, by monitoring UV light exposure for astronauts, which is vital for evaluating cancer risks.
Innovation and Impact
ISRO Chairman Dr. S. Somanath has lauded the SSLV for its "simplicity and production friendliness," highlighting its potential to revolutionize the space industry. He noted that the SSLV is crafted for mass production, allowing for flexible integration and requiring minimal testing before launch. Notably, the entire rocket can be stored and maintained in a state of readiness for rapid deployment.
In a strategic move to privatize India's space program, the government has opened the development of the small satellite launch vehicle to private companies, attracting interest from 20 firms. This initiative is part of a broader strategy to enhance private sector involvement in India's space activities.
Global Market Potential
The global small satellite market, valued at $3.25 billion in 2020, is projected to grow to $13.71 billion by 2030, according to industry reports. This anticipated growth highlights the substantial commercial potential of the SSLV, positioning it as a significant contender in the rapidly expanding small satellite sector.
