Summary

The satellite named STARLINK-3135 (OBJECT_ID: 2021-104S) is a Starlink communication satellite owned by SPXS. It was launched on November 13, 2021, from LC40 at AFETR using the Falcon 9 launch vehicle. The satellite has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters, and it weighs 270 kilograms dry (with an initial launch mass of 290 kilograms). Equipped with Ku/Ka-band payload, optical inter-satellite link, and Krypton ion thrusters for propulsion, the satellite is powered by solar arrays and batteries. The design shape consists of a box structure with a pan configuration, serving as part of SPXS's Starlink Group 4-1-17 constellation mission.

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.
