Summary

The STARLINK-73 satellite, also known as Starlink 73, is owned and operated by SpaceX (SPXS). It was launched on May 24, 2019, from Cape Canaveral Air Force Station Launch Complex 40 (LC40) using a Falcon 9 launch vehicle. The satellite has dimensions of 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters when its components are fully deployed. It weighs 219 kilograms dry with an initial launch mass of 227 kilograms. Equipped with a Ku-band payload for communication purposes, STARLINK-73 uses solar arrays and batteries for power and is propelled by Krypton ion thrusters. Its mission focuses on providing global internet communication services as part of the Starlink V0.9-50 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.
