SpaceX’s Starlink satellites may use unique solar array deployment mechanism
Spotted on an official SpaceX T-shirt commemorating Starlink’s first two prototype satellites and corroborated through analysis of limited public photos of the spacecraft, SpaceX appears to be testing a relatively unique style of solar arrays on the first two satellites launched into orbit, known as Tintin A (Alice) and B (Bob).
It’s difficult to judge anything concrete from the nature of what may be immature prototypes, but SpaceX’s decision to take a major step away from its own style of solar expertise – Cargo Dragon’s traditional rigid panel arrays – is almost certainly motivated by a need to push beyond the current state of the art of satellite design and production.

- Just like a scissor mechanism, Tintin’s solar arrays have an extremely thin sandwich of what looks like four interlocking leaves. (SpaceX)
- If the thin structure is a scissor deployment mechanism, the wider black section would be a housing for wiring and the solar array panels, likely thin and flexible rectangles that fold out to reach their full 6m length. (SpaceX)
Unlike any discernible solar panel deployment mechanism with a flight history, SpaceX’s Starlink engineers seem to have taken a style of deployment used successfully on the International Space Station and mixed it with a modern style of solar arrays, relying on several flexible panels that can be efficiently packed together and designed to be extremely lightweight. While a major departure from SpaceX’s successful Cargo Dragon solar arrays, the mechanisms visible on the Tintins seem to have the potential to improve upon the packing efficiency, ease of manufacturing, and number of failure modes present on Dragon’s panels.
In essence, those three motivations are indicative of the challenges SpaceX’s Starlink program must solve in a more general sense. In order to even approach SpaceX’s operational aspirations for Starlink (i.e. high-speed internet delivered from space almost anywhere on Earth), the company will need to find ways to mass-produce hundreds or thousands of high-performance satellites annually at a price-per-unit unprecedented in the history of commercial satellites, all while keeping the weight and volume of each satellite as low as possible (no more than a few hundred kilograms).
To give an idea of where the industry currently stands, satellite internet provider Viasat launched its own Viasat-2 spacecraft in 2017. Weighing in around 6500 kg (14300 lb), the immense satellite cost at least $600 million and offers an instantaneous bandwidth of 300 gigabits per second, impressive but also gobsmackingly expensive at $2 million/Gbps. To ever hope to make Starlink a reality, SpaceX will need to beat that value by at least a factor of 5-10, producing Starlink satellites for no more than $1-3 million apiece ($4.5B-$13.5B alone to manufacture the initial 4,425 satellite constellation) with a bandwidth of 20 Gbps – baselined in official statements.
Compared to the state of the art, a $1 million satellite with optical (laser) interlinks, multiple phased array antennae, electric ion propulsion, two 1-2 kW solar arrays, and bandwidth on the order of 20 Gbps is – to put it nicely – wildly ambitious. Fundamentally, SpaceX will need to revolutionize design and mass-production of all of the above subcomponents, and perhaps the unfamiliar solar arrays present on the Tintin twins are a first step towards tackling at least one of those revolutions-in-waiting.
Will do another rev before final design

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.

Elon Musk’s Starbase, TX included in $84.6 million coastal funding round
The funds mark another step in the state’s ongoing beach restoration and resilience efforts along the Gulf Coast.
Elon Musk’s Starbase, Texas has been included in an $84.6 million coastal funding round announced by the Texas General Land Office (GLO). The funds mark another step in the state’s ongoing beach restoration and resilience efforts along the Gulf Coast.
Texas Land Commissioner Dawn Buckingham confirmed that 14 coastal counties will receive funding through the Coastal Management Program (CMP) Grant Cycle 31 and Coastal Erosion Planning and Response Act (CEPRA) program Cycle 14. Among the Brownsville-area recipients listed was the City of Starbase, which is home to SpaceX’s Starship factory.
“As someone who spent more than a decade living on the Texas coast, ensuring our communities, wildlife, and their habitats are safe and thriving is of utmost importance. I am honored to bring this much-needed funding to our coastal communities for these beneficial projects,” Commissioner Buckingham said in a press release.
“By dedicating this crucial assistance to these impactful projects, the GLO is ensuring our Texas coast will continue to thrive and remain resilient for generations to come.”
The official Starbase account acknowledged the support in a post on X, writing: “Coastal resilience takes teamwork. We appreciate @TXGLO and Commissioner Dawn Buckingham for their continued support of beach restoration projects in Starbase.”
The funding will support a range of coastal initiatives, including beach nourishment, dune restoration, shoreline stabilization, habitat restoration, and water quality improvements.
CMP projects are backed by funding from the National Oceanic and Atmospheric Administration and the Gulf of Mexico Energy Security Act, alongside local partner matches. CEPRA projects focus specifically on reducing coastal erosion and are funded through allocations from the Texas Legislature, the Texas Hotel Occupancy Tax, and GOMESA.
Checks were presented in Corpus Christi and Brownsville to counties, municipalities, universities, and conservation groups. In addition to Starbase, Brownsville-area recipients included Cameron County, the City of South Padre Island, Willacy County, and the Willacy County Navigation District.

SpaceX targets 150Mbps per user for upgraded Starlink Direct-to-Cell
If achieved, the 150Mbps goal would represent a significant jump from the current performance of Starlink Direct-to-Cell.
SpaceX is targeting peak download speeds of 150Mbps per user for its next-generation Direct-to-Cell Starlink service. The update was shared by SpaceX Spectrum & Regulatory Affairs Lead Udrivolf Pica during the International Telecommunication Union’s Space Connect conference.
“We are aiming at peak speeds of 150Mbps per user,” Pica said during the conference. “So something incredible if you think about the link budgets from space to the mobile phone.”
If achieved, the 150Mbps goal would represent a significant jump from the current performance of Starlink Direct-to-Cell.
Today, SpaceX’s cellular Starlink service, offered in partnership with T-Mobile under the T-Satellite brand, provides speeds of roughly 4Mbps per user. The service is designed primarily for texts, low-resolution video calls, and select apps in locations that traditionally have no cellular service.
By comparison, Ookla data shows median 5G download speeds of approximately 309Mbps for T-Mobile and 172Mbps for AT&T in the United States, as noted in a PCMag report. While 150Mbps would still trail the fastest terrestrial 5G networks, it would place satellite-to-phone broadband much closer to conventional carrier performance, even in remote areas.
Pica indicated that the upgraded system would support “video, voice, and data services, clearly,” moving beyond emergency connectivity and basic messaging use cases.
To reach that target, SpaceX plans to upgrade its existing Starlink Direct-to-Cell satellites and add significant new capacity. The company recently acquired access to radio spectrum from EchoStar, which Pica described as key to expanding throughput.
“More spectrum means a bigger pipeline, and this means that we can expand what we can do with partners. We can expand the quality of service. And again, we can do cellular broadband basically, cellular broadband use cases, like AI or daily connectivity needs,” he stated.
SpaceX has also requested regulatory approval to deploy 15,000 additional Direct-to-Cell satellites, beyond the roughly 650 currently supporting the system. The upgraded architecture is expected to begin rolling out in late 2027.
