Summary
The STARLINK-5634 satellite, also known as Starlink 5634, was launched on January 31, 2023, from the AFWTR launch site using a Falcon 9 launch vehicle. It is part of the Starlink Group 2-6-49 communication mission and operated by SPXS (SpaceX). The satellite measures approximately 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters, featuring a box shape with panels. Equipped with Ku/Ka-band payload and optical inter-satellite link for data transmission, it uses solar arrays and batteries as its power source and krypton ion thrusters for propulsion. At launch, the satellite had a mass of 305 kilograms and a dry mass of 290 kilograms.
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.
