Summary
STARLINK-4789, also known as Starlink 4789, is a communication satellite operated by SPXS (SpaceX) and part of the Starlink Group 4-34-51 mission. It was launched on September 19, 2022, from LC40 at AFETR using a Falcon 9 launch vehicle. The satellite has dimensions of 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters with its deployed structures. Its dry mass is 290 kilograms, and it was launched with a total mass of 305 kilograms. Equipped with Ku/Ka-band payload and an optical inter-satellite link for communication, the satellite also features krypton ion thrusters for propulsion and solar arrays along with batteries for power generation. Its shape consists of a box structure plus panels.
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.
