Summary
The Starlink-2147 satellite, also known as Starlink 2147, is part of SpaceX's Starlink constellation and was launched on March 4, 2021, from Launch Pad LC39A at the Kennedy Space Center using a Falcon 9 launch vehicle. It has dimensions of approximately 0.2 meters in length with a diameter of 2.8 meters and spans about 9 meters. The satellite's dry mass is 248 kg while its launch mass was 260 kg. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links, it serves as a communication satellite using solar arrays for power along with batteries. It utilizes Krypton ion thrusters for propulsion and has a box-shaped body with pan attachments. The ownership of this satellite is attributed to SpaceX.
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.
