SpaceX Unveils New Starlink Satellite Details After Historic Launch
SpaceX reveals new technical details about its Starlink internet satellites following the successful deployment of its heaviest payload ever. The company shares insights into the flat-panel design, phased array antennas, and krypton-powered thrusters.
SpaceX achieves a major milestone by launching its heaviest payload ever, carrying 60 Starlink communications satellites into orbit. Following this successful mission, the company pulls back the curtain to share new details about the spacecraft that will eventually form a global internet constellation. Each flat-panel satellite weighs about 500 pounds and features a design that maximizes the number of units that fit inside a single rocket payload.
The newly launched Starlink website provides the clearest look yet at how the system operates, showing thousands of satellites beaming internet simultaneously to the surface below. Each satellite uses four phased array radio antennas to transmit and receive data in multiple directions and frequencies without requiring any moving parts. The spacecraft also utilizes a single solar array that unfolds upwards to capture sunlight, a choice that prioritizes simplicity and cost efficiency over redundancy.
To navigate space and avoid orbital debris, the satellites rely on a precise Startracker navigation system and a krypton-powered ion thruster. While having only one solar panel means less backup power, SpaceX anticipates replacing these satellites every few years as part of a massive production cycle. These design choices reflect a pragmatic approach to building a scalable space-based internet network that thousands of users will eventually rely on.
