Science Product Pipelines and Archive Architecture for the DART Mission Open
On 2022 September 26, the Double Asteroid Redirection Test (DART) mission was the first successful demonstration of a kinetic impactor for planetary defense. The DART mission utilized a novel autonomous data processing pipeline architectur…

Long-term Monitoring of Didymos with the LCOGT Network and MRO after the DART Impact Open
The world’s first planetary defense test mission was carried out in late 2022 by NASA’s Double Asteroid Redirection Test (DART) mission. The main DART spacecraft, which was accompanied by the ASI-provided LICIACube cubesat, intentionally i…

Photometry of the Didymos System across the DART Impact Apparition Open
On 2022 September 26, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the efficacy of a kinetic impactor for planetary defense by cha…

Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks Open
The impact of the Double Asteroid Redirection Test spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos’s orbit substantially, largely from the ejection of material. We present results from 12 Earth-based facilities i…

Моделирование механических свойств сильно неоднородных систем под внешним воздействием Open
Laboratory tests that were supplemented by a new numerical model have been conducted to study mechanical properties of asteroids with a highly heterogeneous structure. The functional form of the method of molecular dynamics, which was exte…

PHYSICAL CHARACTERIZATION OF ∼2 m DIAMETER NEAR-EARTH ASTEROID 2015 TC25: A POSSIBLE BOULDER FROM E-TYPE ASTEROID (44) NYSA Open
Small near-Earth asteroids (NEAs) (<20 m) are interesting, because they are progenitors for meteorites in our terrestrial collection. The physical characteristics of these small NEAs are crucial to our understanding of the effectiveness of…
