Summary
The satellite named STARLINK-1840 (OBJECT_ID: 2020-088K) is a Starlink communication satellite launched on November 25, 2020, from Cape Canaveral Air Force Station Launch Complex 40 using a Falcon 9 launch vehicle. It has dimensions of 0.2 meters in length and 2.8 meters in diameter with a span of 9 meters. The dry mass is recorded at 248 kilograms while the launch mass was 260 kilograms, indicating it carries solar arrays and batteries for power supply. Equipped with Ku/Ka-band payload and optical inter-satellite links (in prototypes), the satellite employs Krypton ion thrusters as its motor system and has a box plus pan shape design. Manufactured by SPXS (SpaceX) for communication purposes, STARLINK-1840 operates under the ownership of SpaceX.
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.
