SpaceX launches the first 60 Starlink LEO satellites

SpaceX successfully launched the first 60 satellites of its Starlink LEO constellation.

SpaceX has disclosed plans to deploy as many as 12,000 satellites in three, low earth orbit (LEO) shells. Cost estimates for full deployment approach $10 billion.

The launch used a SpaceX Falcon 9 rocket with a first stage that had previously been used on the Telstar 18 VANTAGE mission in September 2018 and the Iridium-8 mission in January 2019. Following the launch, the booster successfully landed on the “Of Course I Still Love You” droneship, which was stationed in the Atlantic Ocean.

The Starlink satellites were deployed at an altitude of 440km. Onboard propulsion was then used to boost each satellite to an operational altitude of 550km.

The Starlink satellites feature a flat-panel design with multiple high-throughput antennas and a single solar array. Each Starlink satellite weighs approximately 227kg.

SpaceX also said the Starlink satellites are able to track and maneuver around orbiting space debris using thrusters powered by Krypton.
