AST SpaceMobile, Inc. ("AST SpaceMobile") (NASDAQ:ASTS), the company building the first and only space-based cellular broadband network accessible directly by everyday smartphones, designed for both commercial and government applications, today announced it has signed a Coordination Agreement with the U.S. National Science Foundation (NSF) to implement best practices between satellite communications and ground-based optical, infrared, and radio astronomy observations.

Under this agreement, AST SpaceMobile commits to collaborate closely with NSF, its major facilities, and the broader U.S. astronomy community to mitigate any potential impact on ground-based astronomical facilities. These efforts will include adopting measures recommended by the International Astronomical Union's Dark and Quiet Skies initiative, such as reducing satellite brightness and providing accurate, real-time satellite positioning data to observatories.

The company's proactive efforts in minimizing interference with astronomical research underscore its dedication to environmental and scientific responsibility.

"We recognize the importance of preserving the night sky for scientific research," said Abel Avellan, Founder, Chairman and CEO of AST SpaceMobile. "This agreement highlights our ongoing commitment to responsible stewardship of space and active cooperation with the global scientific community and ensures that our mission to eliminate connectivity gaps and make broadband accessible to all does not come at the expense of scientific discovery."

AST SpaceMobile's network is designed to deliver cellular broadband connectivity directly from satellites to standard mobile phones, improving connectivity in underserved areas globally and eliminating dead zones. The network will bring millions of Americans into the digital economy and enable access to vital online services such as education, healthcare, banking, jobs, and emergency response.
