Asteroid Justitia is a special main-belt object, being an extremely red body with a steeper spectral slope than any other D-type asteroid. Conversely, its spectral and polarimetric properties resemble organics-rich Centaurs and trans-Neptunian objects ...

Embryonic development of the Mediterranean starfish Hacelia attenuata
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

DART Impact Ejecta Plume Evolution: Implications for Dimorphos
The NASA Double Asteroid Redirection Test (DART) spacecraft impacted the moon Dimorphos of the [65803] Didymos binary system and changed the binary orbit period, demonstrating asteroid deflection by a kinetic impact and indicating that more momentum was ...

ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

The Mineralogical Connection between M- and K-type Asteroids as Indicated by Polarimetry
Polarimetry has the capacity to provide a unique probe of the surface properties of asteroids. Trends in polarization behavior as a function of wavelength trace asteroid regolith mineral properties that are difficult to probe without measurements in situ

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

The Secular Dynamical Evolution of Binary Asteroid System (65803) Didymos Post-DART
The successful impact of NASA’s DART mission with Dimorphos, the secondary body of binary asteroid system (65803) Didymos, altered the attitude, shape, and orbit of Dimorphos.

Taxonomic Classification of Asteroids Using the KMTNet Multiband Photometry Data Set
We report the multiband photometry of asteroids observed over 14 nights from 2015 December to 2017 December using the Korea Microlensing Telescope Network telescopes with the taxonomic classification of those objects. The data set contains the photometry

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Thermophysical Modeling of Asteroid (15) Eunomia from Spatially Resolved ALMA and VLA Data
Asteroid (15) Eunomia is the largest S-type asteroid in the main belt and the largest member of the Eunomia asteroid family. Previous visible-to-mid-infrared data suggested that Eunomia’s hemispheres have different olivine-to-pyroxene ratios and that ∼2%
