ISRO sends largest commercial communications satellite to orbit, Pg1

Key Highlights:

• ISRO successfully launched the BlueBird Block-2 satellite into Low Earth Orbit (LEO) on Wednesday.
• The launch took place from Satish Dhawan Space Centre, Sriharikota, using Launch Vehicle Mark 3 (LVM3) at 8:55 a.m.
• The BlueBird Block-2 satellite weighing 6,100 kg, is the heaviest payload launched by LVM3 from India.
• This mission marks ISRO's first dedicated commercial launch for a U.S. customer, AST SpaceMobile.
• The satellite features a 223m² phased array, enabling direct-to-mobile connectivity via satellite.

Detailed Insights:

• The BlueBird Block-2 satellite is designed to provide space-based broadband connectivity to smartphones, supporting 4G and 5G services.
• The successful launch of BlueBird Block-2 demonstrates the reliability of India's space program and enhances its commercial launch capabilities.
• The LVM3's precision in placing the satellite within two kilometers of the intended orbit showcases its performance in the global launch vehicle arena.
• This mission strengthens the foundation for future missions like Gaganyaan, expands commercial launch services, and deepens global partnerships in space exploration.
• The LEO constellation aims to provide ubiquitous connectivity, enabling voice and video calls, texts, streaming, and data access globally.

Key Concepts Involved:

• Low Earth Orbit (LEO): An orbit around Earth with an altitude of approximately 2,000 km or less.
• Commercial Communication Satellite: A satellite used for relaying communication signals for commercial purposes.
• Phased Array: An antenna system that uses multiple antennas to enhance signal strength and direction.
