Beschreibung:
The final five-and-a-half minutes of images leading up to the DART spacecraft's intentional collision with asteroid Dimorphos. The DART spacecraft streamed these images from its DRACO camera back to Earth in real time as it approached the asteroid. This replay movie is 10 times faster than reality, except for the last six images, which are shown at the same rate that the spacecraft returned them. Both Didymos and its moonlet Dimorphos are visible at the start of the movie. At the end, Dimorphos fills the field of view. The final image in the movie shows a patch of Dimorphos that is 51 feet 16 meters) across. DART's impact occurred during transmission of the final image to Earth, resulting in a partial picture at the end of this movie. Didymos is roughly 2,500 feet (780 meters) in diameter; Dimorphos is about 525 feet (160 meters) in length.

Double Asteroid Redirection TestDer Double Asteroid Redirection Test (DART) ist ein Teil des AIDA-Programms von NASA und ESA. Die Sonde DART flog zu dem Doppelasteroiden Didymos und schlug am 26. September 2022 auf dem Begleiter Dimorphos ein. Der mitgeführte Cubesat LICIACube beobachtete die Kollision. DART ist der erste Versuch in der Geschichte der Weltraumforschung und damit der Menschheit, die Bahn eines Himmelskörpers – in diesem Fall eines erdnahen Asteroiden – zu verändern. .. weiterlesen
