Summary
The STARLINK-5475 satellite, also known as Starlink 5475, is a communication satellite manufactured by SPXS and operated under its ownership. Launched on February 17, 2023, from the AFWTR launch site using the Falcon 9 launch vehicle, it has a dry mass of 290 kg and a launch mass of 305 kg. The satellite is part of the Starlink Group 2-5-34 payload and is equipped with a Ku/Ka-band payload for communication purposes, an optical inter-satellite link, and krypton ion thrusters as its motor system. It measures approximately 0.2 meters in length, has a diameter of 2.8 meters, and spans up to 9 meters. Power supply relies on solar arrays and batteries. The satellite's shape is described as "Box + pan."
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.
