Summary
The satellite STARLINK-2189 (also known as Starlink 2189), identified by NORAD CAT ID 47768 and OBJECT ID 2021-017AY, is part of the Starlink constellation manufactured by SpaceX (SPXS). Launched on March 4, 2021, from LC39A at AFETR using a Falcon 9 launch vehicle, this communication satellite has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters. It weighs 260 kilograms at launch and carries a dry mass of 248 kilograms. The payload includes Ku/Ka-band equipment (all) and optical inter-satellite links for communication purposes, powered by solar arrays and batteries. The satellite uses krypton ion thrusters as its propulsion system.
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.
