Summary
The satellite named STARLINK-2140 (OBJECT_ID: 2021-017J) is a Starlink communication satellite launched on March 4, 2021, from the Kennedy Space Center's Launch Complex 39A 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 as 248 kilograms and it was launched with a mass of 260 kilograms. Equipped with Ku/Ka-band payload and optical inter-satellite links, the satellite uses krypton ion thrusters for propulsion and solar arrays along with batteries for power generation. Manufactured by SpaceX (SPXS) in the US, this satellite is part of the Starlink V1.0-L17-09 constellation designed to provide communication services.
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.
