Three years ago, a space mission made history by altering an asteroid's trajectory. This experiment paved the way for new methods to protect Earth from dangerous celestial bodies. Images captured by ...

In 2022, NASA rammed a spacecraft into an asteroid to see if it could alter its orbital period around its parent asteroid. The mission, dubbed the Double Asteroid Redirection Test (DART), aimed to ...

One of the keyhole probability maps of the asteroid Bennu, The crosshair corresponds to the location on the surface that minimises the asteroid impact hazard after deflection. The maps assume a ...

In December, astronomers calculated that the asteroid YR4 had a small but not insignificant chance of striking Earth in 2032, a scenario that experts postulated could have more explosive potential ...

Blue Origin’s New Glenn rocket, already selected to carry NASA science missions to Mars, is drawing attention as a potential tool for planetary defense against hazardous asteroids. The heavy-lift ...

We need an enhanced version of SUNSET to establish a space-based, combined discovery and early-warning system for NEOs (Near Earth Objects). If we use multiple satellites traveling ahead of Earth on ...

Scientists caution that asteroid deflection must be precise, as striking the wrong spot risks sending it through a gravitational keyhole that sets up a future collision with Earth. Using lessons from ...

Asteroid systems, particularly binary configurations, represent dynamic natural laboratories for studying impact processes and collisional outcomes in our Solar System. Recent advances have shed light ...

A new spacecraft concept called NOVA could keep asteroids from hitting our planet by using a huge magnet to gradually pull ...
