QUE: Recently, the Indian Space Research Organisation (ISRO) launched the EOS-08 satellite using a Small Satellite Launch Vehicle (SSLV). How can this SSLV be beneficial to the Indian space programme?

Recently ISRO successfully launched the EOS-08 Earth Observation Satellite by Small Satellite Launch Vehicle (SSLV-D3) from Satish Dhawan Space Centre (SDSC) in Sriharikota. The Small Satellite Launch Vehicle (SSLV) developed by ISRO offers several strategic advantages to the Indian space programme in terms of deployment of small satellites, commercial opportunities in space and growing demands for national security requirements.

• Role of SSLV in Indian Space Program:

1. Cost-effective launch:

• SSLV is designed to launch small payloads (10-500 kg) into Low Earth Orbit (LEO). It is important for emerging space economies, research institutions and startups as a cost-effective option.
• For example, SSLV makes it possible for small companies to launch their satellites into orbit at low cost.

2. Quick turnaround time:

• SSLV has a simple design and the ability to launch quickly in a short time.

3. Versatility in payload delivery:

• SSLV is capable of launching small satellites into various orbits including Sun-synchronous and Low-Earth orbits. This is important for various applications like Earth observation, environmental monitoring and scientific research.
• For example, satellites like EOS-08, which provide various civil and military services through imaging and remote-sensing techniques.

4. Promoting India’s space diplomacy and commercial opportunities:

• SSLV helps grow India’s commercial satellite launch market by providing services to foreign customers. This also strengthens India’s space diplomacy.

5. Ability to launch more often:

• SSLV will be cost-effective for frequent satellite launches to meet the growing demand for small satellites required for broadband communication or Earth observation.

6. Space Startups and Innovation:

• SSLV offers new opportunities for Indian space startups by providing a cost-effective and dedicated platform to launch their innovative small satellites.
• Recently, with the rise of private participation in India’s space sector, SSLV enables these startups to test new technologies, which fosters innovation in the country’s space ecosystem.
• For example, Indian startups like Pixxel, which work on Earth imaging satellites, can greatly benefit from SSLV’s low-cost launch services.

7. Enhanced national security and strategic autonomy:

• SSLV plays a vital role in strengthening India’s national security by enabling rapid launch of defense and surveillance satellites.
• In a geopolitical arena where real-time intelligence is critical, SSLV provides India with the ability to rapidly launch reconnaissance and communication satellites, and it enhances India’s strategic autonomy by reducing dependence on foreign launch services.
• SSLV can provide fast and immediate essential services that are essential in satellite applications for disaster management. For example, launching satellites for real-time monitoring during natural disasters like floods or earthquakes.

SSLV can help ISRO and India become a leader in space science. SSLV also helps meet the growing satellite launch requirements through cost-effective and flexible launch, which will play a significant role in increasing India’s contribution to the space economy.
