☆ Kessler Syndrome: Space junk is clouding Earth’s orbit. Is it past the point of no return?

“So we are heading towards the situation that we are always dreading.”The event Reddy referred to is a hypothetical phenomenon called Kessler Syndrome. Named for American astrophysicist Donald Kessler and based on his 1978 academic paper, Kessler Syndrome — as the term is used today — has a muddy definition. Given that “Kessler Syndrome” is not an instantaneous event, scientists are debating whether the phenomenon could already be in motion. The researchers interviewed for this story offered differing perspectives on whether events indicative of Kessler Syndrome had already kicked off. But Frueh said that’s why she no longer believes Kessler Syndrome is a useful term.

Elon Musk, whose Starlink satellite constellation is the biggest, wields power in the new Trump administration. SpaceX's Starlink and other mega-constellations of satellites could damage the atmosphere in ways we don't yet understand, scientists say. About 100 scientists signed a letter in October asking the Federal Communications Commission, which regulates satellite launches in the US, to pause mega-constellations. A SpaceX Falcon 9 rocket carrying 56 Starlink internet satellites launches from Cape Canaveral, Florida. Without an environmental review, it's unclear what the impact of SpaceX's Starlink plans will be.
