Asteroid deflection technologies

Asteroid deflection technologies are methods and strategies developed to prevent potential impacts of asteroids with Earth. These technologies aim to alter the trajectory of an asteroid to ensure it does not collide with our planet Following the success of NASA's DART (Double Asteroid Redirection Test) mission, discussions about planetary defense and asteroid deflection strategies are increasingly prominent. Here are some principal methods and how they work: 1. Kinetic Impactor:    - How It Works: This method involves sending a spacecraft to collide with an asteroid at high speed. The impact changes the asteroid's velocity and trajectory, ideally enough to avoid a collision with Earth.    - Example: NASA's DART (Double Asteroid Redirection Test) mission successfully demonstrated this technique by impacting the moonlet Dimorphos in 2022. 2. Gravity Tractor:    - How It Works: A spacecraft positioned near an asteroid uses its gravitational pull to...

Humankind's most distant outpost was recently captured crossing the face of our enormous and gleaming sun. The fleeting transit of the International Space Station was over in the blink of an eye, but Ian Griffin, Director at the Otago Museum of New Zealand, made sure he was in the right place to capture it.
