Summary
The STARLINK-2405 satellite, also known as Starlink 2405, is a communication satellite owned and operated by SpaceX (SPXS). It was launched on March 14, 2021, from Launch Complex 39A at the Kennedy Space Center using a Falcon 9 launch vehicle. The spacecraft measures 0.2 meters in length with a diameter of 2.8 meters and spans 9 meters when deployed. Equipped with a Ku/Ka-band payload and optical inter-satellite links (prototypes), it has a dry mass of 248 kg and launched at 260 kg, powered by solar arrays and batteries, with propulsion provided by krypton ion thrusters. The satellite's shape is described as "Box + pan," suitable for its mission to provide communication services.

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.
