After Jeff Bezos’s New Glenn rocket failed to put BlueBird 7 into orbit, AST SpaceMobile will use Elon Musk’s trusty Falcon 9 to help build out AST’s space-based cellular broadband network useable by everyday smartphones. The delivery of those giant BlueBird 8, 9, and 10 satellites — which feature the largest commercial communications arrays ever deployed in low Earth orbit — is currently scheduled for Wednesday, June 17th.
