Presented here are the observations and interpretations from a comprehensive analysis of
16 representative particles returned from the C-type asteroid Ryugu by the Hayabusa2 …

Abstract Japan Aerospace Exploration Agency (JAXA) launched the asteroid exploration
probe “Hayabusa2” in December 3rd, 2014, following the 1st Hayabusa mission. With …

The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173)
Ryugu. The mission performed two landing operations to collect samples of surface and …

This paper presents a comprehensive review of the science and technology of accessing
near-Earth asteroids (NEAs), or making them accessible, for obtaining both information and …

Establishing the abundance and physical properties of regolith and boulders on asteroids is
crucial for understanding the formation and degradation mechanisms at work on their …

The reflectance spectra of the most abundant meteorites, ordinary chondrites, are different
from those of the abundant S-type (mnemonic for siliceous) asteroids. This discrepancy has …

Martian moons exploration, MMX, is the new sample return mission planned by the Japan
Aerospace Exploration Agency (JAXA) targeting the two Martian moons with the scheduled …

Regolith particles on the asteroid Itokawa were recovered by the Hayabusa mission. Their
three-dimensional (3D) structure and other properties, revealed by x-ray microtomography …

We present an experimental study on ion irradiation of carbonaceous chondrites, simulating
solar wind irradiation on primitive asteroids, to better constrain the space weathering …

The ubiquity of Lyman alpha (Lyα) emission in a sample of four bright [O iii]-strong star-
forming galaxies with redshifts above seven has led to the suggestion that such luminous …
