Summary

The STARLINK-3621 satellite, also known as Starlink 3621, is a communication satellite manufactured by SpaceX (SPXS) and launched on February 25, 2022, from Space Launch Complex 4E at Vandenberg Space Force Base using a Falcon 9 launch vehicle. The spacecraft measures 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. It has a dry mass of 275 kilograms and a launch mass of 297 kilograms. Equipped with Ku/Ka-band payload, an optical inter-satellite link, and Krypton ion thrusters for propulsion, it is powered by solar arrays and batteries. The satellite's shape is described as "Box + pan" and its mission purpose is communication.

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.
