Summary
The STARLINK-4128 satellite, also known as Starlink 4128, is part of the Starlink constellation and was launched on July 24, 2022, from LC39A at AFETR using a Falcon 9 launch vehicle. It has dimensions of 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. The satellite's dry mass is 275 kg, and its launch mass was 297 kg. Equipped with Ku/Ka-band payload and an optical inter-satellite link, it uses Krypton ion thrusters for propulsion. Its power system consists of solar arrays and batteries. Manufactured by SPXS, STARLINK-4128 is owned by the same entity and operates under a communication mission purpose. The satellite's shape is described as a box with a pan configuration.
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.
