In-flight calibration of ESA Hera's HyperScout-H imager
G. P. Prodan, M. Popescu, J. de León +21
ESA's Hera space mission is on its way to the mission target, the binary asteroid (65803) Didymos. HyperScout-H, one of the instruments onboard Hera, is a hyperspectral imager oper…
Polarimetry and albedo of the Near-Earth Asteroid 2025 FA22
J. -P. Rivet, S. Bagnulo, P. Bendjoya +17
We report spectropolarimetric and broadband polarimetric observations of the near-Earth asteroid 2025 FA22 during its close approach of 18 September 2025 (about two Moon distances)…
Rapid-response characterization of near-Earth asteroid 2024 YR4 during a Torino Scale 3 alert
Maxime Devogèle, Olivier R. Hainaut, Marco Micheli +32
On 27 December 2024, near-Earth object (NEO) 2024 YR was discovered by the ATLAS survey and identified as a virtual impactor. A few weeks later, it eventually reached level 3 o…
HyperScout-H: the hyperspectral imager for the ESA Hera mission
Marcel M. Popescu, Julia de León, George Pantelimon Prodan +16
The HyperScout-H (HS-H) instrument is one of the payloads aboard ESA's Hera spacecraft. Hera is a planetary defence mission that aims to provide a detailed characterization of the…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Ejecta from the DART-produced active asteroid Dimorphos
Jian-Yang Li, Masatoshi Hirabayashi, Tony L. Farnham +61
Some active asteroids have been proposed to be the result of impact events. Because active asteroids are generally discovered serendipitously only after their tail formation, the p…
