ISRO LAUNCHES EARTH OBSERVATION SATELLITE EOS-08

Launch Overview

• Satellite: Earth Observation Satellite EOS-08 (primary payload) and SR-O DEMOSAT (secondary payload developed by Space Kidz India).
• Launch Vehicle: Small Satellite Launch Vehicle (SSLV)-D3 (third developmental flight).
• Launch Site: Satish Dhawan Space Centre, Sriharikota.
• Orbit: Circular Low Earth Orbit (LEO) at 475 km altitude with 37.4° inclination.
• Mission Life: 1 year.

Key Details

1. EOS-08:
   • Designed for Earth observation (EO) to monitor natural and human-made systems (physical, chemical, biological).
   • Applications: Early warning systems, environmental impact assessment, disaster management, and resource monitoring.
2. SR-O DEMOSAT:
   • A demonstrator satellite built by Space Kidz India, showcasing indigenous capabilities in space technology.

About SSLV-D3:

• Purpose: Launches mini, micro, or nano satellites (10–500 kg) into 500 km planar orbits.
• Stages:
  • First 3 stages: Solid fuel-based.
  • Final stage: Liquid fuel-based (velocity trimming module).
• Advantages:
  • Low cost and rapid turnaround time (launch readiness within 72 hours).
  • Minimal infrastructure requirements, making it ideal for small satellite deployments.

Significance of the Mission:

• SSLV Program: Enhances India’s competitiveness in the global small satellite launch market.
• EO Capabilities: Strengthens India’s remote sensing infrastructure for climate, agriculture, and security applications.
• Youth Engagement: SR-O DEMOSAT highlights ISRO’s collaboration with private/educational entities to foster innovation.

Thinking Process:

1. Structured Breakdown: Organized the information into sections (launch overview, satellite details, SSLV specifics, and mission significance) for clarity.
2. Key Focus Areas: Highlighted technical specs (orbit, inclination), payload purposes (EOS-08 vs. DEMOSAT), and SSLV’s strategic advantages.
3. Contextualization: Linked the mission to broader goals (e.g., India’s space economy, youth engagement in STEM).
4. Simplification: Avoided jargon (e.g., “velocity trimming module” instead of technical terms) to ensure accessibility.
5. Verification: Cross-checked numerical data (altitude, inclination) and ensured alignment with ISRO’s public communications.
