Summary
The satellite STARLINK-5839 (OBJECT_ID: 2023-088D) is a Starlink communication satellite launched on June 22, 2023, from AFWTR SLC4E using a Falcon 9 launch vehicle. With dimensions of 0.2 meters in length and a diameter of 2.8 meters, the satellite features solar arrays and batteries for power supply. Its primary equipment includes a Ku/Ka-band payload and an optical inter-satellite link. The satellite's dry mass is 290 kilograms, and it was launched with a total mass of 305 kilograms. Equipped with Krypton ion thrusters, STARLINK-5839 operates within the Starlink Group 5-7-04 constellation for communication purposes. Manufactured by SPXS, the satellite is owned by SpaceX (SPXS).
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.
