Some active asteroids have been proposed to be formed as a result of impact events.
Because active asteroids are generally discovered by chance only after their tails have fully …

Abstract In 2003, comet 67P/Churyumov–Gerasimenko was selected as the new target of
the Rosetta mission as the most suitable alternative to the original target, comet …

On February 14, 2011 Stardust-NExT (SN) flew by Comet Tempel 1, the target of the Deep
Impact (DI) mission in 2005, obtaining dust measurements and high-resolution images of …

Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The
comet's outer layer is composed of 1-to 100-micrometer fine particles with negligible …

We apply recently updated scaling laws for impact cratering and ejecta to interpret
observations of the Deep Impact event. An important question is whether the cratering event …

Abstract The Double Asteroid Redirection Test (DART) had an impact with Dimorphos (a
satellite of the asteroid Didymos) on 26 September 2022. Ground-based observations …

Spitzer Space Telescope imaging spectrometer observations of comet 9P/Tempel 1 during
the Deep Impact encounter returned detailed, highly structured, 5-to 35-micrometer spectra …

The last 15 years have seen a surge of new multi-chip optical and near-IR imagers. While
some of them are accompanied by specific reduction pipelines, user-friendly and generic …

We have monitored the Didymos–Dimorphos binary asteroid in spectropolarimetric mode in
the optical range before and after the DART impact. The ultimate goal was to obtain …

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 …
