Summary
The STARLINK-2017 satellite, also known as Starlink 2017, is a communication satellite operated by SPXS (SpaceX). Launched on January 20, 2021, from LC39A at AFETR using a Falcon 9 launch vehicle, it has a dry mass of 248 kg and was launched with a mass of 260 kg. The satellite measures 0.2 meters in length, 2.8 meters in diameter, and its solar arrays span 9 meters. It is equipped with Ku/Ka-band payload (all) and optical inter-satellite links (on prototypes), powered by solar arrays and batteries, and uses Krypton ion thrusters for propulsion. Its mission focuses on communication services as part of the Starlink constellation.

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.
