Summary
The STARLINK-3146 satellite, also known as Starlink 3146, is part of the Starlink constellation and was launched on November 13, 2021, from Cape Canaveral Air Force Station’s Launch Complex 40 using a Falcon 9 launch vehicle. It measures approximately 0.2 meters in length with a diameter of 2.8 meters and spans up to 9 meters when its components are extended. The satellite has a dry mass of 270 kilograms and weighed 290 kilograms at the time of launch. Equipped with Ku/Ka-band payload and optical inter-satellite link, it is designed for communication purposes and is powered by solar arrays and batteries. It utilizes krypton ion thrusters for propulsion and was manufactured by SpaceX (SPXS). The satellite's shape can be described as a box with additional pan elements.

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.

The Satellite That Found 22 Photons and Changed Astronomy

On April 27, 1961, a Scout rocket lifted a 37-kilogram NASA satellite into orbit from Wallops Island carrying the first serious instrument for detecting cosmic gamma rays. Explorer 11 operated for seven months before its tape recorder failed. In that time it registered 22 gamma-ray photons - a pitiful number by modern standards, but enough to launch an entire branch of astronomy.
