Using its heaviest launch vehicle, the LVM3-M6, the Indian Space Research Organization (ISRO) successfully completed a significant commercial space mission by launching BlueBird Block-2, a next-generation US communication satellite. The launch, which took place on Wednesday from the Satish Dhawan Space Centre (SDSC), Sriharikota, is yet another important turning point in India’s expanding involvement in the international commercial space economy.
Powered by two enormous S200 solid strap-on boosters, the 43.5-meter-tall LVM3 rocket took off from the second launch pad at Sriharikota, which is about 135 kilometers east of Chennai, at precisely 8.55 am. The mission demonstrated ISRO’s operational accuracy and technological dependability after a 24-hour countdown was successfully completed.
The BlueBird Block-2 satellite was detached from the launch vehicle and sent into its targeted Low Earth Orbit (LEO) at an altitude of around 520 kilometers, according to ISRO, following a mission that lasted about 15 minutes. The deployment satisfied all performance criteria and mission goals with great precision.
Commercial mission under the NSIL contract
The launch was carried out in accordance with a specific commercial contract between US based AST SpaceMobile (AST & Science, LLC) and NewSpace India Limited (NSIL). India’s position in the global launch services market is strengthened by NSIL, the commercial arm of ISRO, which is in charge of arranging and carrying out commercial satellite launch services for foreign clients.
This mission demonstrates ISRO’s increasing capacity to facilitate large-scale international commercial launches, particularly for next-generation satellites that need for heavy-lift vehicles like the LVM3. It also illustrates the growing trust that international private companies have in India’s technical know-how and space launch infrastructure.
Block-2 of BlueBird and worldwide connectivity
A vital component of AST SpaceMobile’s worldwide LEO constellation, which aims to enable direct-to-mobile satellite connection, is the BlueBird Block-2 satellite. Even in rural and underdeveloped areas of the world, the constellation is built to deliver seamless 4G and 5G services, including voice calls, video calls, messaging, data, and streaming.
BlueBird Block-2 is the biggest commercial communications satellite ever launched into Low Earth Orbit thanks to its enormous 223 square meter phased-array antenna, which is one of its most striking characteristics. Because of its sophisticated architecture, the satellite can communicate directly with common mobile devices without the need for specialized ground infrastructure.
According to ISRO authorities, the satellite was launched at a height of around 600 kilometers, guaranteeing the best coverage and operational effectiveness for the purpose for which it was designed.
A little change to the launch time
On the day of the launch, the original lift-off time of 8.54 am was changed to 8.55 am. According to ISRO officials, the alteration was made to guarantee accurate orbital insertion in response to modifications in mission time specifications.
According to an ISRO official, “the lift-off was originally scheduled for 11.30 am, but it was gradually revised and finally fixed at 8.55 am to meet the desired orbital conditions.”
Bolstering the commercial space credentials of India
ISRO’s reputation as a dependable and affordable launch service provider is strengthened by the successful launch of the heaviest foreign satellite from Indian territory. It also demonstrates how India might use its own launch vehicles to support cutting-edge commercial missions.
ISRO continues to play a crucial role in facilitating global connectivity solutions and advancing India’s economic and strategic interests in the quickly developing space economy with projects like BlueBird Block-2.
