A NASA Spacecraft Will Collide With an Asteroid . Watch Live Here


On September 26 at 11.15 pm UTC, NASA’s DART mission (Double Asteroid Redirection Test) will be the first to deliberately and measurably change the motion of a significant body in our Solar System.

In other words, it will smash into an asteroid.

The mission will provide the first test of a technique that could be used in the future – to redirect any asteroids we detect on a collision course with Earth.

For decades, scientists around the world have been scanning the sky, searching for potentially hazardous asteroids in the vicinity of Earth. And as astronomers discover near-Earth asteroids in ever greater numbers, attention is now turning toward how we might protect Earth should an asteroid on a collision course be discovered. One technique is brute force, and to test it, DART will collide with the 560-foot-wide (170 m) Dimorphos at 7:14 p.m. EDT (2314 GMT) on Sept. 26.

Dimorphos is a member of a binary system with another asteroid, the 2,600-foot-wide (780 m) Didymos, making it the ideal target with which to measure our deflection capabilities. DART’s so-called “kinetic impact” will alter Dimorphos’ orbit around Didymos, and because the two rocks are gravitationally bound, there’s no chance that the impact could send Dimorphos accidentally careening across space.
