European satellite operator Eutelsat "plans to launch 440 Airbus-built LEO satellites in the coming years to replenish and expand its constellation," Reuters reported Friday. And last week America's Federal Communications Commission approved SpaceX's request to deploy another 7,500 Starlink satellites, while Starlink "projects it will eventually have a constellation of 34,000 satellites," writes Fast Company, and Amazon's Project Leo "plans to launch more than 3,200 satellites."
Meanwhile "Beijing and some Chinese companies are planning two separate mega-constellations, Guowang and G60 Starlink, totaling nearly 26,000 satellites," and this week the Chinese government "applied for launch permits for 200,000 satellites."
But a small Texas-based company called AST SpaceMobile "believes it can provide better service with fewer than 100 gigantic satellites in space."
AST SpaceMobile has developed a direct-to-cell technology that utilizes large satellites called BlueBirds. These machines use thousands of antennas to deliver broadband coverage directly to standard mobile phones, says the company's president, Scott Wisniewski. "This approach is remarkably efficient: We can achieve global coverage with approximately 90 satellites, not thousands or even tens of thousands required by other systems," Wisniewski writes in an email...
The key is its satellites' size and sophistication. AST's first generation of commercial satellite, the BlueBird 1-5, unfolds into a massive 693-square-foot array in space. Today, the company has five operational BlueBird 1-5 satellites in orbit, but its ambitions are much bigger. On December 24, 2025, AST launched the first of its next-generation satellites from India — called Block 2 — and this one broke records. The BlueBird 6 has a surface of almost 2,400 square feet, making it the largest single satellite in low Earth orbit. The company plans to launch up to 60 more by the end of 2026. "This large surface area is essential for gathering faint signals from standard, unmodified mobile phones on the ground," Wisniewski explains. It is essentially a single, extremely powerful and sensitive cell tower in the sky, capable of serving a huge geographical area...
To be clear, AST SpaceMobile's approach is not without its own controversies. The sheer size of the company's satellites makes them incredibly bright in the night sky, a significant source of frustration for ground-based astronomers. McDowell confirms that when it launched in 2022, AST's prototype satellite, BlueWalker 3, became "one of the top 10 brightest objects in the night sky for a while."
"It's a serious issue, and we are working directly with the astronomy community to mitigate our impact," Wisniewski says. The company is exploring solutions like anti-reflective coatings and operational adjustments to minimize the time its satellites are at maximum brightness...
AST SpaceMobile has already proven its technology works, the article points out, with six working satellites now transmitting at typical 5G speeds directly to regular phones.
