Summary
STARLINK-2125 is a Starlink satellite, identified by NORAD CAT ID 47725 and OBJECT ID 2021-017D, launched on March 4, 2021, from Launch Pad LC39A at AFETR using the Falcon 9 launch vehicle. It was manufactured by SPXS (SpaceX) for communication purposes. The satellite has a box plus pan shape with dimensions of 0.2 meters in length and 2.8 meters in diameter, with a span of 9 meters. Its dry mass is 248 kilograms and its launch mass is 260 kilograms. It is powered by solar arrays and batteries, and equipped with Ku/Ka-band payload (all) and optical inter-satellite links (a few prototypes). The satellite uses krypton ion thrusters for propulsion and operates in a communication mission.
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.
