Summary

The STARLINK-2112 satellite, also known as Starlink 2112, is a communication satellite part of SpaceX's Starlink constellation. Launched on January 20, 2021, from Kennedy Space Center LC39A aboard a Falcon 9 launch vehicle, the spacecraft has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters. It weighs 248 kilograms dry and had a launch mass of 260 kilograms. The satellite is equipped with Ku/Ka-band payload (all) and optical inter-satellite links on prototypes, powered by solar arrays and batteries, and uses Krypton ion thrusters for propulsion. Its shape resembles a box with a pan configuration.

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.
