Summary
STARLINK-3104 is a communication satellite manufactured by SpaceX and launched on September 14, 2021, from Space Launch Complex 4E at Vandenberg Air Force Base using a Falcon 9 launch vehicle. It has a dry mass of 275 kilograms and was deployed with a launch mass of 297 kilograms. The satellite measures 0.2 meters in length, 2.8 meters in diameter, and features a span of 9 meters due to its solar arrays. Equipped with Ku/Ka-band payload capabilities and an optical inter-satellite link, it uses Krypton ion thrusters for propulsion and is powered by solar arrays and batteries. The satellite's mission involves communication services as part of the Starlink Group 2-1-20 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.
