Summary
STARLINK-4739 is a communication satellite part of the Starlink Group 4-2-20 constellation, manufactured by SPXS and owned by SpaceX (SPXS). Launched on September 11, 2022, from LC39A at AFETR using a Falcon 9 launch vehicle, it has dimensions of 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters. The satellite carries a Ku/Ka-band payload and an optical inter-satellite link with krypton ion thrusters for propulsion. It uses solar arrays and batteries for power generation. At launch, the satellite weighed 305 kilograms and has a dry mass of 290 kilograms. Its primary mission is communication.
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.
