The "NEO Hunter" mission would use Blue Origin's Blue Ring spacecraft to deflect space rocks. This plan builds on NASA's successful DART mission, which proved an asteroid's path could be altered.

A new study reveals all five fundamental nucleobases – the molecular “letters” of life – have been detected in samples from the asteroid Ryugu. Asteroid particles offer a glimpse into the chemical ...

It may sound fanciful, but a Los Angeles-based company says it has conceived of a plan to fly out to a smallish, near-Earth asteroid, throw a large bag around it, and bring the body back to a “safe” ...
