Summary

The STARLINK-2091 satellite, also known as Starlink 2091, was launched on February 16, 2021, from the Cape Canaveral Space Force Station using a Falcon 9 launch vehicle. It is part of SpaceX's Starlink constellation and has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and spans about 9 meters. The satellite has a dry mass of 248 kilograms and was launched with a total mass of 260 kilograms. Equipped with Ku/Ka-band payload capabilities (all) and optical inter-satellite links (on prototype models), STARLINK-2091 uses krypton ion thrusters for propulsion and solar arrays along with batteries for power generation. Its primary mission is communication.

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.
