SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. The Starlink Mobile network will expand Starlink’s vision by providing ubiquitous connectivity and seamless access to text, voice, and data for phones and devices across the globe. The Starlink Mobile network leverages the infrastructure we’ve built for Starlink and provides cellular service through an additional constellation of satellites.
