Pada 24 November 2021, NASA meluncurkan pesawat ruang angkasa Double Asteroid Redirection Test (DART) pada roket SpaceX Falcon 9 dari Space Launch Complex 4 East di Vandenberg Space Force Base di California, AS.<ref name=Greshko-2021-11-23>{{cite news |last=Greshko |first=Michael |date=2021-11-23 |title=This NASA spacecraft will smash into an asteroid – to practice saving Earth |website=[[National Geographic]] |lang=en |url=https://www.nationalgeographic.com/science/article/nasas-dart-spacecraft-will-smash-into-an-asteroid-to-practice-saving-earth |url-status=live |access-date=2021-11-25 |archive-url=https://web.archive.org/web/20211123113703/https://www.nationalgeographic.com/science/article/nasas-dart-spacecraft-will-smash-into-an-asteroid-to-practice-saving-earth |archive-date=2021-11-23 }}</ref><ref>{{cite press release |last=Potter |first=Sean |date=2021-11-23 |title=NASA, SpaceX Launch DART: First test mission to defend planet Earth |website=NASA |url=http://www.nasa.gov/press-release/nasa-spacex-launch-dart-first-test-mission-to-defend-planet-earth |access-date=2021-11-25}}</ref> DART adalah percobaan pertama untuk mempertahankan Bumi dari asteroid berbahaya, dan pesawat ruang angkasa mencoba membelokkan Dimorphos sedikit dari posisinya.<ref name=Rincon-2021-11-24>{{cite news |last=Rincon |first=Paul |date=2021-11-24 |title=NASA DART asteroid spacecraft: Mission to smash into Dimorphos space rock launches |lang=en-GB |website=[[BBC News]] |url=https://www.bbc.com/news/science-environment-59327293|access-date=2021-11-25}}</ref> Pesawat ruang angkasa menabrak Dimorphos dengan kecepatan sekitar 15.000 mph (6,6 km/s)<ref name=Rincon-2021-11-24/> pada 26 September 2022.<ref>{{cite press release |last=Potter |first=Sean |date=2021-11-23 |title=NASA, SpaceX Launch DART: First test mission to defend planet Earth |website=NASA |publisher=[[National Aeronautics and Space Administration]] |url=http://www.nasa.gov/press-release/nasa-spacex-launch-dart-first-test-mission-to-defend-planet-earth |access-date=2021-11-25}}</ref> Tabrakan itu diperkirakan akan membawa Dimorphos dan Didymos lebih dekat satu sama lain.<ref name=Temming-2020-06-29/><ref name=Crane-2021-11-23>{{cite magazine |last=Crane |first=Leah |date=2021-11-23 |title=NASA's DART mission will try to deflect an asteroid by flying into it |magazine=[[New Scientist]] |lang=en-UK |url=https://www.newscientist.com/article/2298530-nasas-dart-mission-will-try-to-deflect-an-asteroid-by-flying-into-it/ |url-status=live |access-date=2021-11-25 |archive-url=https://web.archive.org/web/20211123132010/https://www.newscientist.com/article/2298530-nasas-dart-mission-will-try-to-deflect-an-asteroid-by-flying-into-it/ |archive-date=2021-11-23 }}</ref> Dimorphos kemudian akan mengelilingi Didymos lebih cepat dari sebelumnya, sehingga orbitnya dipersingkat setidaknya 10 menit.<ref name=Rincon-2021-11-24/><ref name=Temming-2020-06-29/>
=== Pengamatan pasca-tabrakan ===
Pesawat ruang angkasa DART didampingi oleh LICIACube, Cubesat flyby dari Badan Antariksa Italia (ASI) 6 Unit, dirilis 15 hari sebelum tumbukan untuk merekam tabrakan.<ref name=Greshko-2021-11-23/><ref>{{cite press release |title=DART's small satellite companion tests camera prior to Dimorphos impact |website=NASA.gov |publisher=[[National Aeronautics and Space Administration]] |url=https://www.nasa.gov/feature/dart-s-small-satellite-companion-tests-camera-prior-to-dimorphos-impact |access-date=25 September 2022}}</ref> Baik LICIACUbe<ref>[https://twitter.com/LICIACube LICIACube Twitter feed]</ref> dan observatorium ATLAS berbasis Bumi telah mendeteksi semburan ejecta dari dampak DART.<ref>[https://twitter.com/fallingstarIfA ATLAS twitter feed]</ref>
