Summary
The Starlink satellite identified by NORAD CAT ID 47604 and OBJECT ID 2021-009BJ was launched on February 4, 2021, from LC40 at the AFETR launch site using a Falcon 9 vehicle. The satellite is owned and manufactured by SPXS (SpaceX) for communication purposes as part of the Starlink constellation. It has dimensions of 0.2 meters in length, 2.8 meters in diameter, and a span of 9 meters. With a dry mass of 248 kilograms, it weighed 260 kilograms at launch. The satellite is equipped with Ku/Ka-band payload (all), optical inter-satellite links (a few prototypes), solar arrays for power, and krypton ion thrusters as its motor system. Its shape can be described as a box with pan configuration.
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.
