Some years ago, the consensus was that asteroid (16) Psyche was almost entirely metal.
New data on density, radar properties, and spectral signatures indicate that the asteroid is …

As we aim to expand human presence in space, we need to find viable approaches to
achieve independence from terrestrial resources. Space biomining of the Moon, Mars and …

INTRODUCTION Comets and asteroids preserve information on the earliest stages of Solar
System formation and on the composition of its building blocks. The nature of their solid …

The mineralogy of Vesta, based on data obtained by the Dawn spacecraft's visible and
infrared spectrometer, is consistent with howardite-eucrite-diogenite meteorites. There are …

Airless planetary bodies are covered by a dusty layer called regolith. The grain size of the
regolith determines the temperature and the mechanical strength of the surface layers. Thus …

Images obtained by the Optical, Spectroscopic, and Infrared Remote Imaging System
(OSIRIS) cameras onboard the Rosetta spacecraft reveal that asteroid 21 Lutetia has a …

Multispectral images (0.44 to 0.98 μm) of asteroid (4) Vesta obtained by the Dawn Framing
Cameras reveal global color variations that uncover and help understand the north-south …

Abstract Knowledge of water in the solar system is important for the understanding of a wide
range of evolutionary processes and the thermal history of the solar system. To explore the …

Abstract Hayabusa2 is the Japanese Asteroid Return Mission and targeted the
carbonaceous asteroid Ryugu, conducted by the Japan Aerospace Exploration Agency …

Asteroid crater retention ages have unknown accuracy because projectile–crater scaling
laws are difficult to verify. At the same time, our knowledge of asteroid and crater size …
