NASA scientists are hitting an asteroid head-on in a landmark experiment testing strategies that could potentially help save humanity.
The Double Asteroid Redirection Test (DART) is the first attempt to 'bump' an object out away from the planet. The collision is a bid to develop planetary defence techniques that would thwart asteroids from hitting the planet and causing unknown destruction.
The asteroid Dimorphos does not pose a threat, but a $330million (£290million) probe will slam into it in a feat reminiscent of a blockbuster. Keen stargazers can watch the impact as it happens on Monday night.
