Itokawa asteroid – pressnews

[ad_1] The three minute particles from an asteroid called Itokawa show some of these space rocks are vastly older than was thought, and are much tougher. The specks are tiny. No, really tiny. Smaller than the diameter of a hair. But they hold billions of years of history that reveal some of the secrets of asteroids. The three minute particles from an asteroid called Itokawa show some of these space rocks are vastly older than was thought, and are much tougher. And that could mean we need bolder ways to prevent catastrophic collisions with Earth, according to research published Tuesday. The three samples were collected in 2005 from the peanut-shaped Itokawa, some 300 million kilometres (186 million miles) from Earth. It took the Japanese spacecraft Hayabusa five years to return...

[ad_1] An asteroid, no more than a pile of rubble, is extremely hard to destroy. Astronomers believe that if the Earth were ever to face the threat of being struck by it, defending our planet would be impossible. When it comes to defense against asteroids, scientists have some methods that they believe they can rely on. Recently, NASA carried out the Double Asteroid Redirection Test (DART) to see whether a spacecraft colliding with an asteroid can push it away. Another method includes using nuclear weapons to destroy an asteroid. However, astronomers have discovered a class of asteroids, which are indestructible. This means if the Earth ever came face to face with this type of asteroids, a devastating strike is almost inevitable.According to a report published by EurekAlert, the study...
