Summary

The Starlink-2351 satellite, identified by NORAD CAT ID 47891 and OBJECT ID 2021-021AH, is a part of SpaceX's Starlink constellation designed for communication purposes. It was launched on March 14, 2021, from the Kennedy Space Center at Launch Complex 39A using a Falcon 9 launch vehicle. The satellite has dimensions of 0.2 meters in length and 2.8 meters in diameter with an overall span of 9 meters. Its dry mass is 248 kilograms while its launch mass was 260 kilograms, indicating the inclusion of propellant or other consumables at launch. It is equipped with a Ku/Ka-band payload for communication along with optical inter-satellite links and krypton ion thrusters as propulsion. Power is supplied by solar arrays and batteries. The satellite's shape consists of a box with a pan configuration, aligning with its mission to enhance global internet connectivity through the Starlink constellation.

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.
