ISRO's ISRO-05 Satellite: A Comprehensive Overview

1. Introduction / Meaning

The ISRO-05 (ISRO-1-0) satellite has been successfully placed in orbit as planned. This further elevates ISRO's prestige on the global stage and serves as an inspiration for future endeavors.

2. Key Concepts

  • Following the failure of the ISRO-1 satellite launched on January 12, the ISRO-05 was successfully launched.
  • Given the previous failure of ISRO-09, the success of ISRO-05 was of great concern to ISRO scientists.
  • The ISRO-05 satellite was successfully placed in orbit within 19 minutes via a 17-rocket from Earth in the Eurobicol region at 2.55.

3. Features of the Agreement / Event

  • The lifespan of the ISRO-05 satellite is 10 years.
  • It is currently orbiting at an altitude ranging from 171 km to 31,026 km.
  • It captures images from approximately 36,000 km above Earth.
  • ISRO-05 is the 107th foreign mission launched from the Eurobicol center.
  • The ISRO-1 satellite, launched by ISRO via rocket in 2001, weighed only 1,536 kg.

4. Why is it Needed?

  • This is the first time in ISRO's history that a satellite has been placed in orbit at an altitude of 36,000 km.
  • It will undertake Earth observation and research missions.
  • Previously launched 21 remote sensing satellites were placed using Earth's surface or solar energy.
  • It is needed for monitoring India's borders and obtaining critical information for security agencies.
  • This satellite can capture and transmit images of natural disasters such as weather forecasts, storms, and floods.

5. Impact

  • It will enable continuous monitoring of all parts of India.
  • It will aid in taking precautionary measures for weather, floods, and domestic disasters.
  • Previously, much weather-related information was obtained only with the help of foreign satellites, including NASA. Now, ISRO-05 can provide this information independently.
  • Information on climate monitoring, security-related data, and maritime activities can also be obtained through ISRO-05.

6. Drawbacks / Challenges

  • The ISRO-05 satellite weighs 2,367 kg. This posed a challenge to ISRO's rocket technology.
  • The previous failures of ISRO-1 and ISRO-09 satellites presented challenges for ISRO's future projects.

7. Current Relevance

  • Many projects, including ISRO's 'Gaganyaan', are among ISRO's future endeavors.
  • Approximately 8,000 crores have been raised for the Gaganyaan project so far.
  • ISRO-05, launched via the ISRO-17 launch vehicle, is India's first shallow-orbit satellite.

8. Exam Notes

  • ISRO-05 (ISRO-1-0) satellite.
  • Lifespan: 10 years.
  • Weight: 2,367 kg.
  • Orbit: 171 km to 31,026 km.
  • Imaging distance: 36,000 km.
  • This is the 107th foreign mission launched from the Eurobicol center.
  • Launched via the ISRO-17 launch vehicle.

9. Summary

The successful launch of the ISRO-05 satellite is a significant milestone in India's space programs. It provides essential information for national security, weather forecasting, and disaster management, while also laying a strong foundation for ISRO's future projects.
