Summary
The STARLINK-2561 satellite, also known as Starlink 2561 and designated as OBJECT_ID 2021-038BC, is part of the Starlink constellation operated by SpaceX (SPXS). Launched on May 4, 2021, from Launch Pad LC39A at AFETR using a Falcon 9 launch vehicle, this communication satellite has a length of 0.2 meters, diameter of 2.8 meters, and span of 9 meters. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links (a few prototypes), the satellite features Krypton ion thrusters for propulsion and utilizes solar arrays and batteries for power. Its dry mass is 248 kg, while its launch mass was 260 kg. The satellite's shape is described as a box with a pan configuration and serves to provide communication services in orbit.
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.
