Starlink satellite trains , is this the future of the night sky?

Almost 15 years later, seeing the aurora borealis is a bit like a drug, says photographer Ronn Murray. “Once you get a taste for it … you’re always trying to see it again because you get this kind of spiritual high from it.” The lakes by Delta Junction in Alaska weren’t frozen over yet when it was just dark enough to see the magical halation over the night’s sky and another phenomenon Murray instantly knew — a moving train of lights. Guide and part-owner of the Aurora Chasers, an Alaska based tour group, Murray had seen the lineup of satellites a few days prior. He recognized it from other people’s accounts but had never seen it himself. Literally the stars aligned, and the night sky opened up on a drive 150 miles outside of Fairbanks. The footage shows what looks like stars trailing one another amid the emerald glow of the northern lights.

Murray captured the 46 objects launched on Aug. 31 by SpaceX clumped together, reflecting the sun back to observers on Earth. These satellites are part of the growing Starlink constellation aimed at providing broadband internet across the globe, much in the manner Global Positioning System (GPS) provides location data to cellphones around the planet. But unlike GPS, the task requires tens of thousands of satellites for service to work without drops in coverage. In three years, the aerospace company SpaceX, owned by Elon Musk, has gone from 60 satellites to launching over 3,500 Starlinks to date. Nearly half of all active satellites are from SpaceX, according to data from the nonprofit satellite tracker CelesTrak. A recent FCC authorization approved the launch of 7,500 more satellites and a nodding sentiment in the company’s plan to launch 30,000 orbiting internet boxes. A feat, that at this rate, they could achieve before 2050.
