Summary
The STARLINK-2736 satellite, also known as Starlink 2736, is owned and operated by SpaceX (SPXS) for communication purposes. Launched on May 26, 2021, from the Air Force Eastern Test Range (AFETR) at Launch Complex 40 using a Falcon 9 launch vehicle, it has a configuration of Bus Starlink with dimensions including a length of 0.2 meters, diameter of 2.8 meters, and span of 9 meters. Its dry mass is 248 kilograms and its launch mass was 260 kilograms. Equipped with Ku/Ka-band payload (all), it also includes optical inter-satellite links on a few prototypes, powered by solar arrays and batteries. The satellite's propulsion system uses Krypton ion thrusters.
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.
