Summary
The STARLINK-1990 satellite, also known as Starlink 1990 and identified by NORAD CAT ID 47586, is part of the Starlink constellation owned and operated by SpaceX (SPXS). Launched on February 4, 2021, from Cape Canaveral Air Force Station's Launch Complex 40 using a Falcon 9 launch vehicle, this communication satellite has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and a span of 9 meters. It weighs 260 kilograms at launch with a dry mass of 248 kilograms. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links (on a few prototypes), STARLINK-1990 uses solar arrays and batteries for power generation and krypton ion thrusters for propulsion. Its primary mission is communication, featuring a box-shaped design 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.
