Could We Provide Better Cellphone Service With Fewer, Bigger Satellites?
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.

Retailers Rush to Implement AI-Assisted Shopping and Orders
This week Google "unveiled a set of tools for retailers that helps them roll out AI agents," reports the Wall Street Journal, The new retail AI agents, which help shoppers find their desired items, provide customer support and let people order food at restaurants, are part of what Alphabet-owned Google calls Gemini Enterprise for Customer Experience. Major retailers, including home improvement giant Lowe's, the grocer Kroger and pizza chain Papa Johns say they are already using Google's tools to help prepare for the incoming wave of AI-assisted shopping and ordering... Kicking off the race among tech giants to get ahead of this shift, OpenAI released its Instant Checkout feature last fall, which lets users buy stuff directly through its chatbot ChatGPT. In January, Microsoft announced a similar checkout feature for its Copilot chatbot. Soon after OpenAI's release last year, Walmart said it would partner with OpenAI to let shoppers buy its products within ChatGPT. But that's just the beginning, reports the New York Times, with hundreds of start-ups also vying for the attention of retailers: There are A.I. start-ups that offer in-store cameras that can detect a customer's age or gender, robots that manage shelves on their own and headsets that give store workers access to product information in real time... The scramble to exploit artificial intelligence is happening across the retail spectrum, from the highest echelons of luxury goods to the most pragmatic of convenience stores. 7-Eleven said it was using conversational A.I. to hire staff at its convenience stores through an agent named Rita (Recruiting Individuals Through Automation). Executives said that they no longer had to worry about whether applicants would show up to interviews and that the system had reduced hiring time, which had taken two weeks, to less than three days. The article notes that at the National Retail Federation conference, other companies showing their AI advancements included Applebee's, IHOP, the Vitamin Shoppe, Urban Outfitters, Rag & Bone, Kendra Scott, Michael Kors and Philip Morris.

53% of Crypto Tokens Launched Since 2021 Have Failed, Most in 2025
=[ "More than half of all cryptocurrencies ever launched are now defunct," reports CoinDesk, citing a new analysis by cryptocurrency data aggregator CoinGecko. And most of those failures occurred in 2025: The study looked at token listings on GeckoTerminal between mid-2021 and the end of 2025. Of the nearly 20.2 million tokens that entered the market during that period, 53.2% are no longer actively traded. A staggering 11.6 million of those failures happened in 2025 alone - accounting for 86.3% of all token deaths over the past five years. One key driver behind the surge in dead tokens was the rise of low-effort memecoins and experimental projects launched via crypto launchpads like pump.fun, CoinGecko analyst Shaun Paul Lee said. These platforms lowered the barrier to entry for token creation, leading to a wave of speculative assets with little or no development backing. Many of these tokens never made it past a handful of trades before disappearing.
