ISRO Makes History, Successfully Places the Largest Communication Satellite into Orbit, Know the Full Story

India’s space agency, the Indian Space Research Organisation (ISRO), has created history with the successful launch of its final mission of the year. In this mission, ISRO placed the largest commercial communication satellite, BlueBird Block-2, into orbit. Importantly, this was a fully commercial launch carried out for the US-based company AST SpaceMobile. As part of the mission, the BlueBird Block-2 satellite was successfully deployed into Low Earth Orbit (LEO) using ISRO’s LVM3 rocket.

Notably, this launch marked the 6th flight of the LVM3 launch vehicle and its third commercial mission. Over time, LVM3 has earned the nickname “Bahubali” because of its heavy-lift capability. The launch took place from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, at 8:55 am. After around 15 minutes of flight, the satellite separated from the rocket and was placed into orbit at an altitude of about 520 kilometres above the Earth. This mission is part of a commercial agreement between NewSpace India Limited (NSIL) and AST SpaceMobile (AST and Science, LLC).

Meanwhile, PM Narendra Modi welcomed the success of the mission and shared his happiness on social media. He saidthat India’s space programme is becoming more advanced and effective due to the strength of the country’s youth. He also highlighted that LVM3 has shown reliable heavy-lift performance, which strengthens preparations for future missions like Gaganyaan, expands commercial launch services, and deepens global partnerships. According to him, this growing capability and self-reliance will benefit future generations.

Why This Mission Is Important

Firstly, this successful launch significantly strengthens ISRO’s position in the global commercial space sector. The BlueBird Block-2 satellite weighs around 6,500 kilograms, making it the largest commercial communication satellite ever placed in Low Earth Orbit. Earlier as well, India has successfully used the LVM3 rocket for major missions such as Chandrayaan-2, Chandrayaan-3, and the OneWeb satellite launches aimed at providing global satellite internet services.In the OneWeb missions, ISRO deployed a total of 72 satellites into LEO across two launches.

Key Features and Capabilities of the BlueBird Block-2 Satellite

The BlueBird Block-2 satellite is part of a next-generation communication system. If it remains stable in orbit and passes all technical tests, it will allow direct 4G and 5G broadband connectivity to regular smartphones. In other words, users will not need any extra antenna or special hardware. At present, mobile phones depend on ground-based towers for 4G and 5G networks. However, with this satellite system, the role of mobile towers could be greatly reduced.

Moreover, this satellite can extend mobile services to remote areas such as mountains, oceans, and deserts, where network coverage is usually weak or unavailable. As a result, providing 4G and 5G connectivity in such regions will become much easier. Additionally, during natural disasters like cyclones, floods, earthquakes, or landslides—when telecom infrastructure often gets damaged—satellite-based networks remain more reliable. Therefore, BlueBird Block-2 has the potential to play a critical role in emergency communication and disaster management.
