Summary
The STARLINK-2485 satellite, also known as Starlink 2485, is owned by SPXS and was launched on April 7, 2021, from Cape Canaveral Air Force Station (LC40) using a Falcon 9 launch vehicle. It operates for communication purposes and carries a Ku/Ka-band payload along with optical inter-satellite links. The satellite has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and a span of 9 meters, with a dry mass of 248 kilograms and a launch mass of 260 kilograms. It is equipped with Krypton ion thrusters for propulsion and solar arrays along with batteries to generate power. The satellite has a box plus pan shape and its payload identifier is Starlink V1.0-L23-51.
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.
