Despite SpaceX Protests, FCC Clears AST SpaceMobile’s Massive Satellite

At over 2,000 square feet in size, the FM1 satellite is designed to be roughly three times larger than the company's existing BlueBird satellites currently in orbit.

Despite pushback from rival SpaceX, AST SpaceMobile has received FCC approval to launch its massive prototype satellite for phone connectivity from space.

On Friday, the FCC granted AST SpaceMobile an experimental license to essentially test FM1, a giant square-shaped satellite that the company has been aiming to launch this month. 

Although the experimental license prohibits AST from “conducting any commercial operations” through the satellite, the FCC's approval brings the company a step closer to building its satellite-to-phone internet system—avoiding what could have been a prolonged delay.

The FM1 marks AST’s first attempt at sending up a second-generation BlueBird satellite, which spans around 200 square meters — or about three times the size of the company’s first-generation BlueBirds. The FM1 weighs in at nearly 13,000 pounds and features a "phased array antenna" at about 199 square meters, letting it operate as a cell tower in space.

The FM1’s increased size and capability promises to help Texas-based AST SpaceMobile deliver even better satellite internet connectivity to everyday smartphones through carriers including AT&T and Verizon. 

The satellite connectivity is designed to power voice, video calls, and data to users in cellular dead zones. But the company faces a growing rivalry with SpaceX, which is developing its own competing solution in the cellular Starlink service, set to launch through T-Mobile on July 23.

Earlier this year, SpaceX criticized AST’s plans to launch the FM1, pointing out alleged flaws in the company’s application, including its orbital safety plan for the satellite. Last month, the Elon Musk company also seized on the paperwork problems with AST’s application, and urged the FCC to dismiss it. 

“The inconsistencies, discrepancies and inadequacies of AST’s orbital debris showings suggest its system will not promote sustainable operations in low-Earth orbit as the Commission’s rules intend,” SpaceX told the FCC on June 27.

But in response, AST told the commission days later that SpaceX’s objections were baseless and a sign of “anticompetitive behavior aimed at impeding AST SpaceMobile’s progress toward deploying its groundbreaking space-based cellular broadband network.” 

The FCC itself also found many discrepancies and minor errors in AST’s application, asking them to be corrected. However, the Commission's new chair, Republican Brendan Carr, has signaled his overall support for the US to expand and dominate in next-generation satellite services. In April, Carr posted pictures of his visit to AST’s headquarters in Midland, Texas. 

AST’s goal is to kick off its own beta service to consumers early next year. But doing so will depend on whether it can launch enough second-generation BlueBird satellites in the coming months. Currently, the company only has five first-generation BlueBird satellites in orbit when it needs at least 45 to 60 to begin offering continuous service across the US and other markets. AST also still needs to secure regulatory approval from the FCC to operate the BlueBirds for commercial phone activities.

To fly up the satellites, AST has tapped both SpaceX and Jeff Bezos’s Blue Origin. Meanwhile, the FM1 is slated to launch through India’s national space agency.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
