Summary
STARLINK-1973, also known as Starlink 1973, is a communication satellite operated by SPXS (SpaceX). Launched on February 16, 2021, from LC40 at AFETR using a Falcon 9 launch vehicle, this satellite has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters. It carries a Ku/Ka-band payload along with optical inter-satellite links on some prototypes and uses solar arrays and batteries for power. The satellite is equipped with Krypton ion thrusters as motors and has a dry mass of 248 kilograms, weighing 260 kilograms at launch. Its shape consists of 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.
