ISRO: A Legacy of Excellence
Historical Background
ISRO was established on August 15, 1969, as India’s premier space agency. Over the past five and a half decades, it has played a crucial role in advancing the nation’s space program, contributing significantly to scientific research, technological development, and practical applications of space technology.
Current Leadership
Under the chairmanship of Dr. S. Somanath, ISRO continues to push the boundaries of space exploration and satellite technology. The organization’s headquarters in Bengaluru serves as the nerve center for India’s space activities.
The EOS-08 Mission
Launch Details
The EOS-08 satellite is scheduled for launch on August 15, 2024, from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh. This launch site has been the starting point for numerous successful ISRO missions and continues to play a vital role in India’s space program.
Launch Vehicle
The satellite will be carried into orbit by the Small Satellite Launch Vehicle (SSLV)-D3. This launch marks the third and final developmental flight of the SSLV platform, a crucial step in establishing its operational status.
Earth Observation Satellite-08 (EOS-08)
Satellite Specifications
- Type: Remote-sensing microsatellite
- Mass: Approximately 175.5 kg
- Orbit: Circular Low-Earth Orbit (LEO) at an altitude of 475 km
- Operational Lifespan: Approximately 1 year
Capabilities and Applications
The EOS-08 is equipped with advanced imaging technology, allowing it to capture images in both Mid-Wave and Long-Wave infrared bands. This capability enables the satellite to function effectively during day and night, serving various critical applications:
- Disaster Monitoring: Satellite-based surveillance for natural and industrial disasters
- Environmental Monitoring: Tracking changes in ecosystems and environmental conditions
- Fire Detection: Early warning and monitoring of wildfires
- Surveillance: Supporting security and monitoring operations
- Volcanic Activity Observation: Tracking and studying volcanic eruptions
Additional Functions
The satellite will also contribute to:
- Ocean surface wind analysis
- Soil moisture assessment
- Cryosphere studies in the Himalayan region
- Flood detection
- Inland waterbody monitoring
These functions make EOS-08 a valuable asset for climate research, disaster management, and environmental protection.
Small Satellite Launch Vehicle (SSLV)
Overview
The SSLV is ISRO’s answer to the growing demand for launching smaller satellites. It is designed to provide a cost-effective and flexible launch platform for nano, mini, and microsatellites.
Key Features
- Payload Capacity: Up to 500 kg to a 500 km Low-Earth Orbit
- Flexibility: Capable of launching single or multiple satellites in one mission
- Structure: Three-stage rocket with solid propulsion stages and a liquid module final stage
Development History
- SSLV D-1 (August 2022): The first developmental flight, which unfortunately failed to meet mission objectives.
- SSLV D-2 (February 2023): A successful mission carrying three satellites – EOS-07, Janus-1, and AzaadiSAT-2.
- SSLV D-3 (Upcoming, August 15, 2024): The final developmental flight, carrying EOS-08.
Significance
A successful SSLV D-3 mission will mark the operational readiness of the SSLV platform, positioning ISRO to compete in the global small satellite launch market.
