Summary
STARLINK-4458, also known as Starlink 4458, is a communication satellite launched by SpaceX on August 31, 2022, from AFWTR SLC4E using a Falcon 9 launch vehicle. It measures 0.2 meters in length with a diameter of 2.8 meters and spans 9 meters when fully deployed. The satellite has a dry mass of 290 kilograms and a launch mass of 300 kilograms. Equipped with Ku/Ka-band payload for communication purposes, it also features an optical inter-satellite link and is powered by solar arrays and batteries. It uses Krypton ion thrusters as its motor system. The satellite's shape is described as a box with panels.
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.
