NASA warns of potential planet-sized asteroid impact: 72% chance of Earth collision

NASA's hypothetical exercise reveals a 72% chance of a potentially hazardous asteroid hitting Earth, highlighting gaps in Earth's preparedness. The exercise, attended by representatives from various agencies, assessed Earth's ability to respond to such threats. Key gaps include decision-making processes and readiness for space missions. NASA's DART mission confirmed the ability to change an asteroid's trajectory, and NEO Surveyor, launching in 2028, aims to discover hazardous objects early. This exercise underscores the importance of preparedness for potential asteroid impacts.
