NASA scientist Kelly Fast has issued a stark warning about the potential for a catastrophic event known as the 'a-rock-alypse'. She highlights the threat posed by up to 15,000 undetected near-Earth asteroids, each capable of destroying an entire city. These 'city killers' are particularly concerning due to their size, measuring around 500 feet, which makes them difficult to detect. Fast emphasizes that while larger asteroids are known and smaller impacts are common, it's these mid-size asteroids that pose a significant risk. With approximately 25,000 of these interstellar objects passing near Earth, and only 40% of their locations identified, the situation is dire. Fast's primary concern is to 'find asteroids before they find us', and she believes that developing methods to intercept them before they impact is crucial. However, even with recent experiments like NASA's Dart mission, which successfully altered the course of an asteroid, the challenge of defending against 'city killers' remains. The lack of funding for planetary defense measures and the difficulty of replicating the Dart mission's approach make it a complex problem. As scientists continue to monitor asteroids like YR4, which has a 4% chance of impacting the moon in 2032, the need for a comprehensive plan to prevent such disasters becomes increasingly urgent. This situation raises important questions about our preparedness and the potential for a global catastrophe. What do you think?
