Summary

The STARLINK-1891 satellite, also known as Starlink 1891, is a communication satellite under the Starlink constellation operated by SpaceX (SPXS). It was launched on November 25, 2020, from Cape Canaveral Air Force Station's LC40 launch pad using a Falcon 9 launch vehicle. The satellite measures approximately 0.2 meters in length with a diameter of 2.8 meters and a span of 9 meters when fully deployed. It has a dry mass of 248 kilograms and a launch mass of 260 kilograms. Equipped with Ku/Ka-band payload capability (available on all units) and optical inter-satellite links (featured in some prototypes), the satellite is powered by solar arrays and batteries, featuring Krypton ion thrusters for propulsion. The shape of the spacecraft is described as a box with an attached panel or antenna array.

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 Multi-Orbit Myth? Why One Startup Thinks the Satellite Industry Got It Wrong

The satellite industry's biggest operators are betting on multi-orbit architectures that combine LEO, MEO, and GEO into unified networks. A San Francisco startup called Contrivian thinks they've overcomplicated the problem, and the physics might be on its side.
