Summary
STARLINK-1974 is a communication satellite operated by SPXS and launched on February 16, 2021, from Cape Canaveral Air Force Station's Launch Complex 40 using the Falcon 9 launch vehicle. The satellite measures 0.2 meters in length, has a diameter of 2.8 meters, and a span of 9 meters. It has a dry mass of 248 kilograms and was launched with a total mass of 260 kilograms. Equipped with Ku/Ka-band payload and optical inter-satellite links, STARLINK-1974 is powered by solar arrays and batteries, utilizing krypton ion thrusters for propulsion. Its shape consists of a box with a pan configuration and it serves the purpose of communication as part of the Starlink constellation.

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.
