Summary
STARLINK-5851 is a communication satellite part of the Starlink Group 2-8-34 constellation, owned and manufactured by SpaceX (SPXS). It was launched on March 17, 2023, from Space Launch Complex 4E at Vandenberg Space Force Base using a Falcon 9 launch vehicle. The satellite measures 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters, equipped with Ku/Ka-band payload and an optical inter-satellite link for communication purposes. It uses solar arrays and batteries for power generation and is propelled by krypton ion thrusters. The satellite has a launch mass of 305 kilograms and a dry mass of 290 kilograms.
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.
