Summary
The STARLINK-1845 satellite, also known as Starlink 1845, is a communication satellite manufactured by SpaceX (SPXS) and launched on November 25, 2020, from Cape Canaveral Air Force Station, Launch Pad LC40, using a Falcon 9 launch vehicle. It belongs to the Starlink constellation and has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and a span of 9 meters. The satellite's dry mass is 248 kilograms with a launch mass of 260 kilograms. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links (prototypes), it utilizes solar arrays and batteries for power supply and employs krypton ion thrusters as its motor system. Its primary purpose is communication, featuring a box plus pan shape in design.
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.
