NASA Expert Urges Humanity to Prepare for Inevitable Asteroid Impacts

Human civilization must prepare for the inevitable reality of asteroid impacts, according to a leading expert at NASA. Umberto Campins, an asteroid specialist, emphasized that while the risk of a catastrophic impact during any individual's lifetime remains extremely low, such events are a recurring feature of the solar system's history.

Campins clarified that there are currently no known asteroids posing a direct threat to Earth. However, he stressed the critical need for developing long-term strategies to protect the planet. He pointed to major collisions, such as the one believed to have caused the extinction of the dinosaurs millions of years ago, as natural occurrences that underscore the importance of planetary defense.

Human civilization is required to prepare for the possibility of an asteroid colliding with Earth in the future, and such events will inevitably recur.

NASA has been advocating for serious attention to this threat for over three decades, leading to the establishment of an international network of observatories and scientists. This network monitors asteroids and assesses their risk using the Torino Scale, which calculates impact probabilities. International space agencies also conduct periodic simulations every three years to refine response mechanisms for potential impact scenarios.

Individuals have no reason to worry currently, because scientists are not monitoring any asteroid that poses a direct threat to Earth.

Campins cited NASA's DART mission in 2022 as a practical demonstration of planetary defense capabilities. The mission successfully altered an asteroid's trajectory by colliding a spacecraft with it, proving that what was once considered science fiction is now achievable. He also mentioned the upcoming close flyby of the asteroid Apophis in 2029, which, while posing no threat, offers a unique scientific opportunity to study the effects of Earth's gravity on an asteroid.

Beyond the risks, Campins also highlighted the potential economic opportunities presented by asteroids. Some contain valuable resources like water, rare metals such as platinum, and raw materials that could be used for in-space construction. Missions like NASA's OSIRIS-REx have already revealed the presence of water-bearing silicate minerals on asteroids, suggesting future possibilities for extracting water for rocket fuel and supporting space exploration endeavors. He anticipates that asteroid resource utilization projects could begin within the next decade or two, potentially forming a cornerstone for establishing permanent off-world bases.

This experiment practically proved the possibility of implementing what was previously considered science fiction.
