Summary
The STARLINK-11407 [DTC], also known as Starlink 11407, is a satellite from the Starlink V2M bus series launched on November 14, 2024, by SpaceX (SPXS) from Vandenberg Space Force Base (AFWTR), SLC-4E pad, using a Falcon 9 launch vehicle. With dimensions of 0.3 meters in length and 4.1 meters in diameter, it has a dry mass of 700 kg and was launched with a total mass of 730 kg. The satellite's shape is described as "Box + pan," and its primary payload is part of the Starlink Group 9-11-01 constellation. It operates under ownership by SpaceX, but specific details about its power supply, purpose, and major events are not provided.
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.
