TAMPA, Fla. โ€” AST SpaceMobile said June 13 that SpaceX aims to launch the prototype for its cellphone-compatible broadband constellation in the week of Aug. 15.

The actual launch date is subject to final integration of the BlueWalker 3 test satellite, AST SpaceMobile added, and other factors including the SpaceX Falcon 9 rocketโ€™s readiness and weather. 

The launch window announcement comes days after AST SpaceMobile CEO and chair Abel Avellan said BlueWalker 3 had successfully conducted end-to-end tests.

โ€œWe also got the satellite fueled for our planned summer launch,โ€ Avellan tweeted June 10.

BlueWalker 3 was developed at AST SpaceMobileโ€™s facilities in Texas and is slated to launch on a Falcon 9 rocket with other passengers from Cape Canaveral, Florida.

The 1,500-kilogram satellite has a 64-square-meter phased array antenna that is designed to unfold in space to connect standard smartphones and other devices at broadband speeds.

The startup has an experimental license for in-orbit BlueWalker 3 tests to configure ground equipment and software for significantly larger operational satellites called BlueBird.

Avellan said May 16 that BlueBirdโ€™s development is so advanced that it is ready to start deploying the operational satellites in 2023 even if Blue Walker 3 runs into issues.

SpaceX is also slated to launch the first BlueBird. 

By the end of 2024, AST SpaceMobile expects to have deployed 110 of the satellites to provide โ€œsubstantial globalโ€ mobile coverage.[spacenews-ad]
