Images from the first month after the DART spacecraft’s deliberate asteroid collision. Because each frame is the average over an entire night’s observing, the asteroid is in the centre and the stars appear as streaks. (University of Canterbury Ōtehīwai Mt John Observatory/UCNZ) |
Spacecraft knocked 1 million kg off asteroidThe asteroid that was deliberately hit with NASA’s Double Asteroid Redirection Test (DART) spacecraft last September lost one million kilograms of rock, gained a 1,000-kilometre-long debris tail and now completes its orbit 33 minutes faster than before the collision. A detailed analysis of what happened when DART smashed into the Great-Pyramid-sized asteroid Dimorphos has revealed how successful this first test of planetary defence really was. The spacecraft hit a spot close to the asteroid’s centre and caused a large spray of rubble to fly outwards, which maximized the impact’s force and added momentum.
