Summary
The satellite named STARLINK-1873, also known as Starlink 1873, is a communication satellite manufactured by SpaceX (SPXS) and launched on November 25, 2020, from the Cape Canaveral Space Force Station Launch Complex 40 using a Falcon 9 launch vehicle. It has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters when fully deployed. The satellite weighs about 260 kilograms at launch with a dry mass of 248 kilograms. Equipped with Ku/Ka-band payload (all), optical inter-satellite links (some prototypes), solar arrays for power generation, and batteries, it uses Krypton ion thrusters as its motor system. The shape of the satellite is described as a box with an additional pan-like structure.

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.
