Summary
The STARLINK-4346 satellite, also known as Starlink 4346, is a communication satellite belonging to SpaceX's Starlink constellation. It was launched on July 11, 2022, from the AFWTR launch site at SLC4E using a Falcon 9 launch vehicle. The spacecraft has dimensions of 0.2 meters in length and 2.8 meters in diameter, with a span of 9 meters. Its dry mass is 275 kilograms and its launch mass was 297 kilograms. Equipped with Ku/Ka-band payload for communication purposes and optical inter-satellite links, the satellite uses krypton ion thrusters as propulsion and solar arrays along with batteries for power supply. The shape of the satellite is described as a box with panels. It operates in a communication mission under SpaceX ownership.
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.
