Summary

The STARLINK-2128 satellite, also known as Starlink 2128, is owned and operated by SpaceX (SPXS) for communication purposes. Launched on January 20, 2021, from Launch Complex 39A at Kennedy Space Center, Florida, aboard a Falcon 9 launch vehicle, this satellite features a Box + pan shape with dimensions of 0.2 meters in length and 2.8 meters in diameter, while the span is 9 meters. It carries a dry mass of 248 kilograms and has a total launch mass of 260 kilograms. The payload includes Ku/Ka-band communications equipment and optical inter-satellite links on some prototypes, powered by solar arrays and batteries. The satellite uses krypton ion thrusters for propulsion and is part of the Starlink constellation designed to provide global broadband internet coverage.

Starlink is a satellite constellation developed by SpaceX with the aim of providing global broadband internet coverage. Thousands of small satellites are deployed in low Earth orbit (LEO), enabling high-speed internet access even in remote areas. However, the rapid increase in satellites raises concerns about space debris and the potential for collisions, which can lead to further debris creation and endanger other spacecraft. Additionally, the sheer number of Starlink satellites can affect astronomical observations by increasing light pollution. Proper deorbiting plans and international coordination are essential to mitigate these challenges and ensure long-term sustainability in space.
