World's first planetary defence test

post-image

The world’s first full-scale planetary defence test – NASA’s Double Asteroid Redirection Test (DART) mission – is designed to strike an asteroid and adjust its course.

Today the DART spacecraft is expected to collide with a small asteroid, Dimorphos, at a speed of approximately 6.44 km per second.

Dimorphos is 160 metres in diameter, roughly the size of the Great Pyramid of Giza, and orbits a larger companion asteroid, Didymos.

If successful, the DART mission will show that intentionally crashing a spacecraft into an asteroid is an effective way to change its speed and trajectory. What we learn could be applied in future to protect Earth from potentially hazardous asteroids.

I can't wrap my head around how incredible this is! The footage right before impact is jaw dropping. Thanks for sharing!

Yes Matt- I was surprised when people didn't seem to quickly realise how important this idea is!
