What SpaceX's Starlink Satellites Look Like in the Night Sky
In the video, SpaceX's Starlink satellites pass overhead like a string of pearls, a brilliant trail of moving lights in the night sky. SpaceX launched the satellites into an initial orbit 273 miles (440 kilometers) above Earth. They are making their way to a final orbit 342 miles (550 km) up.
"Over the coming days the 'train' of objects will be making 2-3 passes each night," he wrote on his website. "As they are actively manoeuvering with their ion thrusters, they will be more spread out with each pass, so the 'train' will probably quickly dissipate."
Each Starlink satellite is equipped with Krypton ion thrusters to adjust its orbit. They'll use those thrusters to spread apart over time.
