Summary
The Starlink satellite designated as STARLINK-3138 (OBJECT_ID: 2021-104Y) was launched on November 13, 2021, from Launch Complex 40 at the Cape Canaveral Space Force Station aboard a Falcon 9 launch vehicle. It is owned and operated by SpaceX for communication purposes and weighs approximately 270 kg dry with solar arrays and batteries providing power. The satellite is equipped with Ku/Ka-band payload and optical inter-satellite link capabilities, utilizing Krypton ion thrusters as its motor system. With dimensions of 0.2 meters in length, a diameter of 2.8 meters, and a span of 9 meters, it has a box + pan shape and was manufactured by SpaceX (SPXS).
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.
