ISRO launched the GSLV-F17 rocket carrying Earth observation satellite EOS-05 from Sriharikota, enhancing India's remote sensing capabilities for agriculture, disaster management, and climate monitoring.

Key points

GSLV-F17 successfully placed EOS-05 into orbit from Satish Dhawan Space Centre, Sriharikota, marking another milestone in India's space program.

The 51.7-metre tall rocket lifted off after a 27.5-hour countdown, demonstrating ISRO's growing expertise in launch vehicle technology.

EOS-05 is an Earth observation satellite that will significantly enhance India's remote sensing capabilities for applications in agriculture, forestry, and disaster management.

This launch reinforces India's position in the global space sector, particularly in the field of earth observation and remote sensing technologies.

[GS3-Science and Technology] The successful launch showcases India's indigenous capabilities in space technology, a key component of the Science and Technology syllabus.

[GS3-Environment] EOS-05's data will be crucial for climate change monitoring and environmental conservation efforts, aligning with India's commitments under the Paris Agreement.

The launch follows India's recent space policy reforms aimed at encouraging private sector participation in space activities.

Way Forward: India should accelerate its satellite launch frequency, enhance international collaboration in earth observation data sharing, and further liberalize the space sector to attract private investment.

Key terms

GSLV-F17

Geosynchronous Satellite Launch Vehicle (GSLV) is ISRO's launch vehicle capable of placing satellites into geostationary orbit. The F17 variant demonstrates India's growing self-reliance in cryogenic engine technology, crucial for heavy payload launches and strategic space applications.

EOS-05

Earth Observation Satellite-05 is an advanced remote sensing satellite designed for high-resolution imaging of Earth's surface. Its data supports critical national needs including agricultural monitoring, urban planning, disaster management, and defense applications.

Satish Dhawan Space Centre

ISRO's primary launch center located in Sriharikota, Andhra Pradesh. It houses multiple launch pads and tracking facilities, serving as the nerve center of India's space launch operations and a symbol of India's space ambitions.

Remote Sensing

The science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. For UPSC, it's significant for applications in governance (GS2), environment (GS3), and disaster management - key areas in both prelims and mains examinations.
