Normally, spaceships are not designed to crash. However, this is exactly what NASA did, on the night of Monday September 26 to Tuesday September 27, to deviate the trajectory of an asteroid by projecting a kamikaze ship on it. The moment of impact, 11 million kilometers from Earth, could be followed live on the NASA video channel, at the top of this article. The impact occurs precisely at 1’44″57. The ship, no larger than a car, had taken off in November from California. After ten months of travel, the collision took place at 1:14 a.m. on Tuesday, at a speed more than 20,000 km/h. The target was actually a couple of asteroids: a large one, Didymos (780 meters in diameter), and its satellite, Dimorphos (160 meters in diameter), in orbit around it. two are only about a kilometer apart. The smaller one, Dimorphos, was where the spacecraft crashed. Before the collision, the asteroid circled the larger one in 11 hours and 55 minutes, and the goal was to reduce its orbit by about ten minutes. The asteroid which was targeted did not pose any danger. But the mission, named Dart (“dart”, in English), must “help determine our response if we detect an asteroid threatening to hit Earth” in the future, NASA boss Bill Nelson said Monday.
