The race to blanket the planet with satellite internet just gained a giant new contender. A spacecraft billed as the largest commercial communications satellite ever deployed in low Earth orbit has unfolded its vast antenna, and its mission is explicit: turn ordinary smartphones into satellite phones and challenge SpaceX’s Starlink on coverage and capability. Instead of building another dense broadband constellation, its backers are betting that one enormous “cell tower in space” can do the work of hundreds of smaller satellites.
At the center of this bet is AST SpaceMobile’s BlueBird 6, a next generation platform that combines a record breaking antenna with direct to device connectivity aimed at 4G and 5G phones. I see this launch as a pivotal moment in the satellite internet story, not because it adds yet another network to the sky, but because it tests a radically different architecture that could reshape how, and where, we expect our phones to work.
BlueBird 6, the new giant in low Earth orbit
BlueBird 6 is not just another spacecraft joining the crowded shell of low Earth orbit, it is designed as a floating cell tower with a footprint that dwarfs anything flying in commercial communications today. The satellite carries a phased array antenna spanning nearly 2,400 square feet, a surface area that would cover a modest house and yard if laid flat on the ground. That array is central to AST SpaceMobile’s claim that BlueBird 6 is the largest commercial communications structure ever deployed in low Earth orbit, and it is the hardware that will let the satellite talk directly to standard smartphones on the ground.
The company describes BlueBird 6 as part of a new generation of spacecraft that build on earlier test platforms but scale up dramatically in size and capacity. At nearly 2,400 square feet, AST says the satellite is more than three times larger and offers roughly ten times the throughput of its previous BlueBird design, which already pushed the limits of direct to device experiments. That scale is not cosmetic, it is what allows the spacecraft to form narrow, powerful beams that can reach individual phones without the bulky dishes or specialized terminals that define most satellite broadband today.
How India’s PSLV put the behemoth in orbit
Getting a satellite this large into orbit required a carefully choreographed launch and deployment sequence, and AST SpaceMobile turned to India’s workhorse rocket to do it. The BlueBird 6 mission lifted off at 10:25 p.m. EST from the Satish Dhawan Space Centre in Sriharikota, riding an Indian rocket that has become a reliable option for commercial payloads. After separation, AST SpaceMobile confirmed nominal telemetry, a crucial first sign that the satellite survived the ride to orbit and was ready to begin its complex unfolding sequence.
The choice of India’s launch infrastructure underscores how global the new satellite internet race has become. The Indian Space Research Organisation, through its facilities at ISRO, has positioned itself as a competitive provider for missions that need precise insertion into low Earth orbit and a track record of delivering on schedule. For AST SpaceMobile, partnering with this ecosystem offered a way to place its record breaking satellite into the right orbit while keeping costs in check, a reminder that the battle with Starlink is not just about technology in space but also about the economics of getting there.
Inside AST SpaceMobile’s direct-to-phone vision
AST SpaceMobile’s core pitch is deceptively simple: instead of asking users to buy new hardware, it wants their existing phones to connect directly to satellites as if they were ordinary cell towers. On its own site, AST describes a space based cellular broadband network designed to work with standard 4G and 5G devices, turning gaps in terrestrial coverage into seamless extensions of the grid. The company’s Next Gen Bluebird platform is built specifically for this purpose, with satellites engineered to deliver 24/7 high speed cellular broadband and to interoperate with mobile network operators rather than bypass them.
Earlier BlueBirds had antennas around 693 square feet, but the new design scales that up dramatically to the nearly 2,400 square foot array now in orbit, a jump that AST says translates into far higher capacity and more robust links to phones in challenging environments. The company frames these spacecraft as orbital “cellphone towers” that can slot into existing carrier networks, and it has already lined up partnerships with operators such as AT&T, Verizon and Vodafone to test and eventually commercialize the service.
Why BlueBird 6 is aimed squarely at Starlink
AST SpaceMobile is not shy about who it sees as the incumbent to beat. The company’s own messaging and outside analysis both frame BlueBird 6 as a direct response to SpaceX’s Starlink, which has already placed around 10,000 satellites into orbit to build out its broadband network. Where Starlink relies on a vast swarm of relatively small spacecraft and user owned terminals, AST is betting that a smaller number of extremely large satellites can deliver comparable or better service by talking directly to phones and integrating with terrestrial carriers.
That contrast is explicit in coverage that describes BlueBird 6 as a Starlink rival and highlights AST SpaceMobile’s ambition to provide 5G smartphone coverage from orbit. Another analysis notes that AST SpaceMobile release 223 m2 BlueBird 6 to compete with Starlink, underscoring that the satellite’s sheer physical size is part of its competitive strategy. I see this as a clash of architectures as much as brands, with one side optimizing for mass production and density, and the other for reach and integration with existing mobile ecosystems.
Capacity, coverage and the 223 m² question
Size in orbit only matters if it translates into usable capacity on the ground, and AST SpaceMobile is already touting what BlueBird 6 can do. The company says the satellite’s 223 m2, or 223 m2, antenna can support data rates up to 120 megabytes per second to individual devices, a figure that, if sustained in real world conditions, would rival or exceed many terrestrial mobile connections. That performance is not just about raw throughput, it is also about the ability to maintain links over wide areas, including oceans, deserts and rural regions where building towers is uneconomical.
AST has framed BlueBird 6 as over three times the size and roughly ten times the capacity of its earlier satellites, a leap that should allow it to serve far more simultaneous users without the congestion that has plagued some satellite networks. The company’s own description of the Next generation BlueBird architecture emphasizes 24/7 high speed cellular broadband, and outside reporting notes that the new satellite is expected to commence operations in the coming weeks as AST ramps up deployments every one or two months. That cadence, described in coverage of the next BlueBird Block 2 satellite, suggests the company is planning not just a one off demonstration but a scalable network.
From test calls to a 60-satellite network
BlueBird 6 is the latest step in a progression that began with smaller test satellites and headline grabbing phone calls from space. Earlier this year, AST SpaceMobile used its prototype spacecraft to place voice calls and send data to unmodified smartphones, including a regular Samsung Galaxy S22, proving that its direct to device concept could work in practice. Reporting on those tests notes that since then, AST has launched the largest satellite in space for this type of service, a clear reference to BlueBird 6’s record breaking antenna.
The company’s ambitions extend far beyond a single spacecraft. AST SpaceMobile wants to launch up to 60 of its satellites in 2026, building a constellation that can provide near continuous coverage as the Earth rotates beneath their orbits. Coverage of the project, including a piece by By Passant Rabie Published December, frames this as a bid to move from experimental connectivity to a commercial service that can beam broadband from space at scale. I read that roadmap as an aggressive attempt to close the gap with Starlink’s head start, using fewer but more capable satellites to reach a similar global footprint.
Investors, partners and the market’s early verdict
Capital markets have taken notice of BlueBird 6’s successful deployment. Shares of AST SpaceMobile, which trade under the ticker ASTS, rose after the company confirmed that the satellite had reached low Earth orbit, a sign that investors see the mission as a de risked step toward commercial service. The company has described BlueBird 6 as a validation of its direct to device capacity and a platform for future revenue growth, positioning itself as a key player in the emerging market for space based cellular connectivity in LEO.
On the customer side, AST has already secured partnerships that give it a path to millions of users if the technology performs as advertised. In the United States, In the United States, AST has partnered with AT&T and Verizon, while internationally it has lined up carriers that plan to integrate its satellite network into their roaming and emergency coverage. I see these alliances as one of AST’s biggest advantages over Starlink, which has often positioned itself as an over the top provider rather than a wholesale partner to mobile operators.
A crowded sky: Amazon Leo, legacy players and the new competition
BlueBird 6 is arriving in an orbital neighborhood that is already busy and getting more so. Alongside Starlink’s thousands of satellites, Amazon has rebranded its Project Kuiper as Amazon Leo as it prepares to take on Starlink starting in the coming years. A recent Key Points summary of the satellite mobile internet landscape notes that Amazon’s network, AST SpaceMobile’s direct to device system and traditional geostationary providers like Hughesnet and Viasat are all jockeying for position as new services come online and older ones bow out or retool.
In that context, AST’s decision to “go big” with a handful of enormous satellites looks like a deliberate attempt to differentiate itself from both Starlink’s dense swarm and Amazon Leo’s planned constellation. The company is pitching itself as a complement to terrestrial networks rather than a replacement, and its partnerships with carriers suggest it wants to be embedded in existing phone plans rather than sold as a separate subscription. I see this as a recognition that the satellite internet market is fragmenting into niches, with some players chasing RV owners and remote workers, others targeting maritime and aviation, and AST focusing on everyday smartphone users who simply want their phones to work everywhere.
What happens next in the Starlink–AST rivalry
With BlueBird 6 now in orbit, the next phase will be about proving that the satellite can deliver consistent, high quality service to real users and not just in controlled tests. Coverage that describes the mission as the biggest satellite ever to reach low Earth orbit emphasizes that SpaceX may have launched 10,000 Starlink satellites, but now it faces competition that is literally larger in physical scale. The real test will come when AST begins offering service to customers shortly after BlueBird 6 enters operations, and users can compare latency, speed and reliability against Starlink’s established offering.
AST’s own roadmap suggests that BlueBird 6 is just the first of many such satellites, with launches planned every one or two months and a target of up to 60 spacecraft in the near term. Coverage of the project underlines that Starlink Rival Launches Its Largest Satellite Yet for Space Based Cellular Network, and that AST is positioning itself as a long term competitor rather than a niche player. If the company can execute on that plan, the rivalry between these two very different visions of satellite connectivity will shape not just who dominates the market, but how billions of people experience being connected in the first place.
