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...

Two new outbursts detected from the magnetar 1E 1048.1−5937

Using NASA's Neil Gehrels Swift Observatory, astronomers have identified two new outbursts from the magnetar 1E 1048.1−5937. The newly detected events could shed more light on the nature of this source. The finding is detailed in a paper published January 17 on arXiv.org.
