Summary
STARLINK-5861, also known as Starlink 5861, is a communication satellite manufactured by SPXS and owned by SpaceX (SPXS). It was launched on March 17, 2023, from AFWTR using the Falcon 9 launch vehicle from SLC4E. The spacecraft has dimensions of 0.2 meters in length, a diameter of 2.8 meters, and a span of 9 meters. At launch, it had a mass of 305 kilograms, reducing to a dry mass of 290 kilograms. Equipped with Ku/Ka-band payload capabilities and optical inter-satellite links, the satellite uses solar arrays and batteries for power supply. Its propulsion system includes Krypton ion thrusters. The mission of STARLINK-5861 is communication as part of the Starlink Group 2-8-08 constellation, with a shape described as box plus panel 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.
