Summary
The Starlink-3604 satellite, also known as Starlink 3604, was launched on February 25, 2022, from SLC4E at AFWTR using a Falcon 9 launch vehicle. It is part of the Starlink constellation and is owned by SpaceX (SPXS). The spacecraft has dimensions of 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. Its dry mass is recorded as 275 kilograms, and it weighs 297 kilograms at launch. Equipped with a Ku/Ka-band payload and optical inter-satellite link for communication purposes, the satellite utilizes solar arrays and batteries for power. It also features Krypton ion thrusters for propulsion.
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.
