Summary
STARLINK-1621, also known as Starlink 1621, is a communication satellite manufactured by SpaceX and owned by SpaceX. It was launched on August 18, 2020, from the Air Force Eastern Test Range (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 when fully deployed. It carries a Ku/Ka-band payload and optical inter-satellite links for communication purposes. STARLINK-1621 weighs approximately 248 kilograms dry and had an initial launch mass of 260 kilograms. Its power is supplied by solar arrays and batteries, and it uses krypton ion thrusters as its propulsion system. The satellite's shape consists of a box with a 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.
