SRIHARIKOTA (ANDHRA PRADESH) : In a historic Christmas Eve mission, ISRO’s heaviest rocket, LVM3-M6, successfully placed a US communication satellite into orbit on Wednesday.
The Bengaluru-headquartered space agency said the LVM3-M6 has successfully placed the BlueBird Block-2 satellite into its intended orbit.
The Bluebird Block-2 mission is part of a global LEO (Low Earth Orbit) constellation to provide direct-to-mobile connectivity through satellite. This constellation would enable 4G and 5G voice and video calls, texts, streaming and data for everyone, everywhere at all times.
LVM3-M6 carried the communication satellite as part of a commercial deal between NewSpace India Ltd (NSIL) and US-based AST SpaceMobile (AST and Science, LLC).
NewSpace India is the commercial arm of the ISRO.
The 43.5 metre tall rocket soared majestically at 8.54 am from the second launch pad here on Wednesday.
After a flight journey of about 15 minutes, the spacecraft Bluebird Block-2 got separated from the vehicle and it was successfully placed into orbit.
Weighing 6,100 kg, the communication satellite would be the heaviest payload to be placed into the Low Earth Orbit (LEO) in LVM3 launch history from Indian soil, the space agency said.
The previous heaviest was the LVM3-M5 Communication Satellite 03, weighing about 4,400 kg that was successfully launched by ISRO on November 2 in the Geosynchronous Transfer Orbit (GTO).
The mission is aimed at deploying the next-generation communication satellite designed to provide high-speed cellular broadband directly to smartphones.
AST SpaceMobile is building the first and only space-based cellular broadbank network, which is accessible directly by smartphones and designed for both commercial and government applications.
The LVM3-M6 also known as the Geosynchronous Satellite Launch Vehicle (GSLV-MkIII) is a three stage rocket with a cryogenic engine designed and developed by ISRO’s Liquid Propulsion Systems Centre.
The vehicle uses two S200 solid rocket boosters to provide the huge amount of thrust required for lift off. The booster has been developed by Vikram Sarabhai Space Centre, Thiruvananthapuram.
According to AST SpaceMobile, it has launched five satellites, Bluebird 1-5 in September 2024, which provide continuous coverage across the United States and other select countries.
The company has planned to launch similar satellites to augment its network support and has partnered with over 50 mobile operators across the globe.
The LVM3-M6 is the sixth operational flight of LVM3 and third dedicated commercial mission to launch the Bluebird Block-2 spacecraft.
The LVM3 has a spectacular pedigree of completing eight consecutive successful launches including the ambitious Chandrayaan-2, Chandrayaan-3 missions, ISRO said. (Agencies)
