Summary

STARLINK-3631 is a Starlink communication satellite launched on February 25, 2022, from AFWTR SLC4E 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 275 kilograms and was equipped with a Ku/Ka-band payload, an optical inter-satellite link, and Krypton ion thrusters for propulsion. The satellite's power is provided by solar arrays and batteries. Launched as part of the Starlink Group 4-11-23 mission, it operates in a communication capacity. The satellite was manufactured by SpaceX (SPXS) and owned by the same entity.

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.
