Summary
The satellite named STARLINK-3639, also known as Starlink 3639, is a communication satellite belonging to the Starlink constellation operated by SpaceX (SPXS). Launched on February 25, 2022, from AFWTR SLC4E using a Falcon 9 launch vehicle, it has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters. The satellite weighs approximately 275 kilograms dry and 297 kilograms at launch. It is equipped with a Ku/Ka-band payload for communication purposes and an optical inter-satellite link, powered by solar arrays and batteries. Its propulsion system includes krypton ion thrusters.
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.
