Summary

The STARLINK-2135 satellite, also known as Starlink 2135, is owned by SPXS and was launched on January 20, 2021, from LC39A at AFETR using a Falcon 9 launch vehicle. It measures approximately 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters. The satellite has a dry mass of 248 kilograms and weighed 260 kilograms at launch. Equipped with a Ku/Ka-band payload and optical inter-satellite links, STARLINK-2135 is part of the Starlink constellation designed for communication purposes. It uses solar arrays and batteries for power generation and employs krypton ion thrusters as its motor system. The satellite's shape is described as box-like with a pan configuration, and it was manufactured by SPXS.

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.

The Civilian Space Traffic System America Almost Didn't Build

For nearly two decades, the U.S. Air Force and Space Force have been the world's unofficial civilian space traffic control system. The Department of Commerce's Traffic Coordination System for Space (TraCSS) is now taking over that job for commercial satellite operators - in stages, against persistent congressional pressure to kill the program, and with Department of Defense advocates pushing to make it happen before it is too late.
