Summary

STARLINK-4491 is a communication satellite under the Starlink program, owned and operated by SpaceX (SPXS). Launched on August 10, 2022, from LC39A at AFETR using a Falcon 9 launch vehicle, it has a dry mass of 275 kg and measures 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. The satellite is equipped with Ku/Ka-band payload for communication purposes and an optical inter-satellite link. It uses solar arrays and batteries for power supply, and its propulsion system consists of Krypton ion thrusters. Its shape can be described as box-shaped 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.
