Summary
The STARLINK-2473 satellite, also known as Starlink 2473, is part of SpaceX's Starlink constellation and was launched on April 7, 2021, from Cape Canaveral Air Force Station using a Falcon 9 launch vehicle. The spacecraft measures approximately 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. It has a dry mass of 248 kilograms and was launched at a mass of 260 kilograms. Equipped with Ku/Ka-band payload (all), optical inter-satellite links (a few prototypes), and Krypton ion thrusters for propulsion, the satellite is designed for communication purposes. Power generation is provided by solar arrays and batteries. The spacecraft's shape consists of a box structure with an attached pan element.

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.
