It’s a question we’ve been getting with more and more frequency in the KSAT weather studio: “What’s that weird line of lights in the night sky?”
And, to be fair, the lights do look a little creepy — a perfect train of lights marching across the sky. Almost as if they were put there by intelligent beings 🤔.
Well, turns out WE are intelligent beings! To be specific, the line of lights is Starlink satellites.
Starlink is a network of satellites operated by Elon Musk’s SpaceX company.
The first satellites were deployed in 2019, so the line of lights in the sky is a new phenomenon. As of July 2023, there are over 4,000 Starlink satellites in orbit with plans to deploy more than 10,000 in the coming years.
The purpose of the satellites is to provide internet access across the globe. The satellites communicate with ground stations, the nearest of which is located in New Braunfels. There are four other ground stations located in Texas: Boca Chica, Sanderson, McGregor, and Hampshire.
With thousands of these satellites in low Earth orbit, there is a concern about light pollution from astronomers and general stargazers, making it more difficult to observe the natural night sky.
The Starlink satellites are just a part of the thousands of satellites in orbit right now. As the number of satellites grows, there is some concern for collisions leading to space “junk” or debris falling uncontrollably back to Earth.
The good news is that Starlink satellites are small enough and designed to completely burn up before reaching Earth’s surface.
A live map of where Starlink satellites are located can be found here. An approximation of times when the train of satellites will be visible can be found here.
