Summary
STARLINK-4721 is a communication satellite launched by SpaceX (SPXS) on September 11, 2022, from LC39A at the Kennedy Space Center using a Falcon 9 launch vehicle. The spacecraft measures 0.2 meters in length and has a diameter of 2.8 meters with a span of 9 meters. It has a dry mass of 290 kilograms and a launch mass of 305 kilograms, equipped with Ku/Ka-band payload and an optical inter-satellite link for communication purposes. The satellite is powered by solar arrays and batteries and uses krypton ion thrusters as its propulsion system.
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 Satellites the Size of a Studio Apartment
AST SpaceMobile's BlueBird constellation is a bet that raw aperture size wins. Each satellite unfolds a 64-square-meter phased-array antenna in orbit, the largest commercial antenna ever deployed. The company claims a stock smartphone on the ground can connect directly to it. The competition says the physics doesn't support that. Seventeen satellites in and a contract with AT&T, Verizon, and Vodafone, somebody's math is wrong.
