On September 21, AST SpaceMobile, Inc. rose 5.18% in regular trading, trading at approximately $61.34 per share, with turnover of $132 million. The stock had plunged 6.68% in the prior session to $58.52, giving today's rebound a clear oversold recovery character.

On the news front, the broader space sector received multiple catalysts. SpaceX's upcoming first revenue-generating Starship mission lifted industry sentiment, with peers SpaceX gaining 2.02%, Anterix surging 8.26%, and Iridium climbing 1.38%. Additionally, market speculation emerged that United Launch Alliance (ULA) could face a potential sale, with AST SpaceMobile cited as a possible dark horse acquirer, drawing attention from investors.

Fundamentally, AST SpaceMobile continues to advance its satellite constellation buildout. The company recently launched BlueBird satellites 11 through 13 and disclosed a patent covering its Block 2 array technology targeting near-200 Mbps peak speeds for standard smartphones. However, questions linger over the launch timeline for BlueBird 14-16, with no firm dates announced despite earlier indications that the satellites were near completion. The company targets 45 satellites in orbit by early next year.
