Context
- Grahaa Space, a Bengaluru-based spacetech start-up, has secured launch authorisation from IN-SPACe for its maiden nano-satellite mission — Solaras S2.
• The satellite will be launched by the end of November as a technology demonstration mission.
Key Highlights
About the Solaras S2 Mission
- Type: Nano-satellite technology demonstration.
• Objective:
→ Qualify Grahaa’s nano-satellite bus/platform.
→ Assess spaceworthiness & performance for future deployment.
• Launch Site: Alcântara Space Center (CEA), Brazil.
• Launch Vehicle: Hanbit-Nano rocket developed by Innospace (South Korea).
Start-up’s Future Roadmap
- Early 2026 missions with Skyroot (India):
→ To validate communications module.
→ Capture geospatial data via optical payload.
→ Establish inter-satellite links (ISL) for satellite networking.
Institutional Support
- IN-SPACe — Granted authorisation for launch.
• TIIC incubation centre at IIST Trivandrum — Technical support for development.
Relevant Prelims Points
- IN-SPACe (Indian National Space Promotion and Authorisation Centre):
→ Autonomous body under Department of Space.
→ Promotes and authorises private sector participation in India’s space activities. - Nano-satellites:
→ 1–10 kg category; low cost & quick development.
→ Deployed for Earth observation, IoT, communication experiments, remote sensing. - Hanbit-Nano Launch Vehicle:
→ Developed by Innospace (South Korea) for small satellite launches. - Alcântara Space Center, Brazil:
→ Equatorial launch site — provides fuel & performance advantage for certain orbits. - Skyroot Aerospace:
→ Hyderabad-based private launch vehicle developer — Vikram series rockets.
Relevant Mains Points
Significance for India’s Private Space Sector
- Reinforces India’s shift from ISRO-led to ISRO-plus-private ecosystem.
• Facilitates commercial satellite development & launch capability by start-ups.
• Encourages foreign launch collaboration (Brazil + South Korea) while preparing for domestic launch with Skyroot.
Technological Importance
- Nano-satellite bus qualification is a critical milestone for scalable satellite constellations.
• Upcoming missions to focus on:
→ Optical geospatial imaging
→ Satellite networking (inter-satellite links) → key for real-time EO and broadband constellations.
Economic & Strategic Implications
- Strengthens India’s potential in global NewSpace markets — Earth observation, defence analytics, agri & climate intelligence, logistics optimisation.
• Boosts space-based services exports and supports convergence of AI + EO + telecom.
Challenges Ahead
- Capital-intensive nature of satellite constellations.
• Market competition from SpaceX (Starlink), Planet Labs, BlackSky, etc.
• Need for clear licensing rules for downstream geospatial data.
Way Forward
- Support via IN-SPACe single-window clearances and faster satcom/geospatial policy rollout.
• Incentivise export-oriented EO analytics & dual-use tech innovation.
• Strengthen PPP model around ISRO infrastructure + private manufacturing.
