Summary
The STARLINK-2373 satellite, also known as Starlink 2373, is part of SpaceX's Starlink constellation designed for communication purposes. Launched on March 11, 2021, from the Cape Canaveral Space Force Station using a Falcon 9 launch vehicle, it has a length of 0.2 meters and a diameter of 2.8 meters with a span of 9 meters. It weighs 260 kilograms at launch and its dry mass is 248 kilograms. The satellite uses solar arrays and batteries for power and is equipped with Ku/Ka-band payload (all) and optical inter-satellite links (a few prototypes). Its propulsion system consists of Krypton ion thrusters, and it has a box plus pan shape according to the available data.
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.
