ISSI-BJ Webinar on NASA's DART Mission | Andy Cheng

ABOUT THIS WEBINAR
The NASA Double Asteroid Redirection Test (DART) mission will be the first space experiment to demonstrate asteroid deflection by a kinetic impactor. DART will impact Dimorphos, the secondary member of the (65803) Didymos system, in late September - early October 2022 in order to change the binary orbit. DART will carry to Didymos a 6U CubeSat called LICIACube, contributed by the Italian Space Agency, to document the DART impact on Dimorphos and to observe the impact ejecta. DART will use ground-based telescopes to determine the orbital period change caused by the impact on Dimorphous. Besides, the DART spacecraft observations consist of approach imaging to measure Didymos light curves to determine rotation and orbital characteristics, further approach imaging to measure the sizes and shapes of Didymos and Dimorphos, and terminal approach imaging to determine the impact site location and local surface geology. LICIACube will observe the structure and evolution of the DART impact ejecta plume and image the non-impact hemispheres of Didymos and Dimorphous. We will update DART status and discuss DART determinations of the momentum transfer efficiency and new modeling results of DART impact outcomes.
