Shares of AST SpaceMobile (NASDAQ: ASTS) climbed 2% overnight Sunday after a regulatory filing signaled that direct-to-cell satellite operations in Japan could begin imminently. The filing, submitted to the Federal Communications Commission, confirmed AST SpaceMobile would launch non-U.S. direct-to-cell operations with its mobile network operator partners in the near term. Adding to investor optimism, AST SpaceMobile announced over the weekend that its BlueBird satellites received Guinness World Records recognition for deploying the largest commercial communications arrays in low-Earth orbit. The push for domestic-controlled satellite services creates an interesting opportunity for players already building global networks.” Every successful BlueBird launch chips away at the execution concerns.
