Summary

The Starlink-3120 satellite, also known as Starlink 3120 and identified by its OBJECT_ID 2021-104M, is a communication satellite manufactured by SpaceX (SPXS). Launched on November 13, 2021, from the Cape Canaveral Air Force Station (AFETR) using a Falcon 9 launch vehicle, this satellite has dimensions of 0.2 meters in length, 2.8 meters in diameter, and a span of 9 meters. It carries a Ku/Ka-band payload and an optical inter-satellite link for communication purposes. The dry mass is recorded at 270 kilograms with a launch mass of 290 kilograms. Its power system includes solar arrays and batteries. Equipped with Krypton ion thrusters as its motor, the satellite's shape is described as 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.
