EUTELSAT 172B
Europe's first high-power all-electric telecom satellite doesn't just sit above the Pacific - it got there on robotic arms and plasma thrusters, broke records doing it, and now keeps your airplane Wi-Fi running between LA and Tokyo.

Summary
STARLINK-3901 is a communication satellite launched on May 13, 2022, from Space Launch Complex 4E at Vandenberg Air Force Base using a Falcon 9 launch vehicle. The spacecraft, part of the Starlink Group 4-13-39, measures 0.2 meters in length and has a diameter of 2.8 meters with a span of 9 meters. It features Ku/Ka-band payload capabilities along with optical inter-satellite links for data transmission and employs krypton ion thrusters as its motor system. The satellite's dry mass is 275 kilograms, while its launch mass was 297 kilograms, powered by solar arrays and batteries. Manufactured by SpaceX (SPXS), it serves a communication mission, owned by the same entity, with no further details provided on major events or materials composition.
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.
