The Indian Space Research Organisation (ISRO) is preparing for a landmark commercial launch as its heavy-lift rocket LVM3 is scheduled to place a next-generation communication satellite into orbit on December 24. The mission, designated LVM3-M6, will deploy the BlueBird Block-2 satellite for U.S.-based space communications company AST SpaceMobile, marking a significant milestone in global satellite-based mobile connectivity.
The mission aims to enable high-speed cellular broadband services delivered directly to standard smartphones, without the need for specialised satellite hardware. If successful, the launch will strengthen ISRO’s position as a reliable global commercial launch provider while advancing next-generation communications infrastructure.
A Commercial Mission with Global Impact
ISRO confirmed that the LVM3-M6 mission is a dedicated commercial launch conducted under an agreement between NewSpace India Limited (NSIL) and AST SpaceMobile (AST & Science, LLC). NSIL serves as ISRO’s commercial arm and oversees international launch contracts.
AST SpaceMobile is developing the world’s first space-based cellular broadband network designed to work directly with existing smartphones. The company says its mission is to eliminate coverage gaps faced by nearly six billion mobile users and to extend broadband access to regions that currently lack reliable connectivity.
The upcoming launch represents a major step toward achieving that goal.
BlueBird Block-2: A Technological Leap
The BlueBird Block-2 satellite has been engineered to deliver 24/7 high-speed cellular broadband directly to smartphones across the globe. According to AST SpaceMobile, the satellite will support 4G and 5G voice calls, video calls, text messaging, streaming, and data services from low Earth orbit.
One of the most notable features of the satellite is its 223-square-metre phased-array antenna, making it the largest commercial communications satellite ever deployed into low Earth orbit. ISRO said the spacecraft will also be the heaviest payload launched by the LVM3 rocket into low Earth orbit to date.
The satellite forms part of a broader low Earth orbit constellation planned by AST SpaceMobile to enable direct-to-mobile connectivity worldwide.
Expanding a Growing Satellite Network
AST SpaceMobile has already launched five satellites BlueBird 1 to BlueBird 5 in September 2024. These satellites currently support continuous internet coverage across the United States and selected international regions.
The company plans to expand its constellation through additional launches, including the BlueBird Block-2 mission, to enhance global coverage and network capacity. AST SpaceMobile has also partnered with more than 50 mobile network operators worldwide, positioning itself as a key player in the emerging satellite-to-smartphone connectivity market.
LVM3’s Proven Track Record
The LVM3 rocket, formerly known as Gaganyaan Mark-III, is ISRO’s most powerful launch vehicle and has a strong record of complex missions. It has previously launched major spacecraft including Chandrayaan-2, Chandrayaan-3, and two OneWeb missions carrying a total of 72 satellites.
ISRO’s most recent LVM3 mission, LVM3-M5/CMS-03, successfully placed a communication satellite into orbit on November 2, 2025, further reinforcing confidence in the vehicle ahead of the December launch.
Strengthening India’s Commercial Space Presence
The LVM3-M6 mission underscores India’s growing role in the global commercial space market. With rising demand for low Earth orbit satellite launches, ISRO’s ability to deliver heavy payloads reliably and cost-effectively has attracted increasing international interest.
Officials say the December 24 launch will not only showcase India’s launch capabilities but also contribute to the future of global digital connectivity.
As satellite-based broadband emerges as a solution for remote and underserved regions, the success of the BlueBird Block-2 mission could mark a turning point in how mobile networks reach users across the world.
