BlueWalker 3 is the world's largest communications satellite and it is a testbed for a roughly 100-satellite constellation designed to beam broadband internet straight to smartphones., a team of scientists detailed their observations of BlueWalker 3's brightness over 130 days, showing that it is now one of the brightest objects in the night sky.
"Broadly speaking, the negative impacts stem from number and brightness of the satellites," she continued, adding that it's difficult to compare the impact of different constellations in a constantly shifting landscape. What's more, the cleanup project would be comparable to "collecting bullets" from Earth orbit, Lawler added, due to the speed at which space debris flies around our planet.that SpaceX's mega-constellation could decrease "our planet's ability to detect and possibly redirect a potentially catastrophic impact."
"SpaceX continues to set industry standards for testing and deploying darkening mitigations on their hardware," Rawls said. "However, the newest Starlink satellites are significantly larger than older ones, so even state-of-the-art darkening technology cannot guarantee that satellites will be dimmed to the extent astronomers prefer or in all phases of their life cycle."
