Summary
STARLINK-1644, also known as Starlink 1644, is a communication satellite operated by SpaceX (SPXS). It was launched on October 6, 2020, from Cape Canaveral Air Force Station's Launch Complex 39A using a Falcon 9 launch vehicle. The satellite has dimensions of approximately 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters when fully deployed. It weighs 260 kilograms at launch with a dry mass of 248 kilograms and is powered by solar arrays and batteries. Equipped with Ku/Ka-band payload capabilities and optical inter-satellite links, it utilizes Krypton ion thrusters for propulsion. Its shape is described as "Box + pan," and it serves the purpose of communication within SpaceX's 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.

SpaceX Launches 29 Starlink Satellites From Cape Canaveral | KeepTrack X Report
SpaceX deploys 29 Starlink satellites from Cape Canaveral on the Starlink 6-100 mission. Falcon 9 lifted off at 6:31 p.m. EST continuing SpaceX's dominant satellite internet market position.
The Telescope That Needed Glasses
On April 25, 1990, the Space Shuttle Discovery's robotic arm lifted a 11,110-kilogram barrel of mirrors and instruments out of the payload bay and released it into orbit. Six weeks later, the first images came back badly out of focus. The Hubble Space Telescope had been ground to the wrong prescription, and America had just spent $2.5 billion on what the press was calling a 'technoturkey.'
