Summary
The STARLINK-3155 satellite, also known as Starlink 3155, is part of the Starlink constellation and was launched on December 2, 2021, from Cape Canaveral Air Force Station's LC40 launch pad using a Falcon 9 launch vehicle. The satellite measures 0.2 meters in length with a diameter of 2.8 meters and spans 9 meters. It has a dry mass of 270 kilograms and was launched with a mass of 290 kilograms. Equipped with Ku/Ka-band payload and an optical inter-satellite link, the satellite is designed for communication purposes. It uses krypton ion thrusters as its motor and solar arrays along with batteries for power supply. The satellite reached stable orbit on December 3, 2021. It was manufactured by SpaceX (SPXS) and owned by 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.
