NASA's DART mission reshaped an asteroid moon, Dimorphos, causing it to change shape from a hamburger to a football and potentially setting it on a chaotic new path. The impact may have also caused Dimorphos to tumble unpredictably, challenging previous beliefs about asteroid moons. The success of the mission opens new possibilities for planetary defense strategies.
