El Double Asteroid Redirection Test (DART) el jera na NASA mision spasiàl che ła ga el scopo de testàr un metodo de difexa planetaria contro ogeti tereni (NEOs).[1][2] El xe stà progetà pa vałutàr cuanto un inpato de nave spasiàl el devia un asteroide co el so trasferimento de momentum co el colpise l’asteroide de fronte.[3] L'asteroide obietivo sełesionà, Dimorphos, el xe un luna de pianeta minore de l'asteroide Didymos; nisùn dei do asteroidi el xe na minacia de inpato pa ła Tera, ma łe so carateristiche comuni łe li ga fati deventar un obietivo de riferimento ideałe. Lancià el 24 novenbre 2021, ła nave spasiàl DART ła ga scontrà co Dimorphos el 26 setenbre 2022 ałe 23:14 UTC dała Tera. Ła cołixion ła ga scurtà l’orbita de Dimorfo de 32 minuti, tanto in pì del limite de suceso predefinìo de 73 secóndi.[4][5][6] El suceso de DART nel deviar Dimorphos el xe stà dovùo al trasferimento de momento asocià al rinculo dei detriti butài fora, che el jera tanto pi grando de queło causà da l’inpato steso.[7]
DART el jera un progeto congiunto tra ła NASA e el Johns Hopkins University Applied Physics Laboratory. El progeto el xe stà finansià dała NASA Planetary Defense Coordination Office, gestìo dała NASA Planetary Missions Program Office al Marshall Space Flight Center, e diversi laboratori e ufici deła NASA i ga fornìo suporto tecnico. L’Italian Space Agency el ga contribuio a LICIACube, un CubeSat che el ga fotografà l’evento de inpato, e altri partner internasionałi, come ła European Space Agency (ESA), e Japan Aerospace Exploration Agency (JAXA), i xe drìo contribuir a projeti rełativi o sucesivi.[8]
