Abstract On September 24, 2023, NASA's OSIRIS‐REx mission dropped a capsule to Earth
containing~ 120 g of pristine carbonaceous regolith from Bennu. We describe the delivery …

Nowadays, asteroid and comet exploration is one of the most important components of deep
space exploration. Through asteroid and comet exploration missions, it is possible to reveal …

An asteroid's interior dictates how its space environment changes its shape and surface,
which provides a record of the collisional and dynamical evolution of the Solar System …

The radar circular polarization ratio (CPR) is an indicator of near-surface, wavelength-scale
complexity. Interestingly, previous surveys also noted an association between near-Earth …

Spectral characterization of near-Earth asteroids (NEAs) has revealed a continuum of space-
weathered states for the surfaces of S-complex NEAs, with Q-class NEAs, an S-complex …

Context. Near-Earth objects (NEOs) are the most accessible small Solar System bodies by
both spacecrafts and ground-based telescopes. Close encounters of these objects with …

Aims. We present a model for the distribution of dust ejected by asteroids and comets. Our
model incorporates the effects of solar gravity and radiation pressure. In specific cases it can …

Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer
(OSIRIS-REx) was a NASA New Frontiers–class asteroid sample return mission to (101955) …

Near-Earth object 2024 MK was discovered on 2024 June 16, less than 2 weeks before it
made a sub-lunar-distance close approach. This close approach provided an ideal …

This paper presents Bennunet, a hybrid neural network-based method, devoted to on-board
spacecraft relative position and attitude estimation in the vicinity of minor bodies using …
