Puzzlingly, the parent bodies of ordinary chondrites (the most abundant type of meteorites) do not seem to be abundant among asteroids. One possible explanation is that surfaces of the parent bodies become optically altered, to become the S-type asteroids which are abundant in the main asteroid belt. The process is called ‘space weathering’—it makes the visible and near-infrared reflectance spectrum of a body darker and redder. A recent survey of small, near-Earth asteroids suggests that the… 
Solar wind as the origin of rapid reddening of asteroid surfaces
TLDR
The rapid colour change found implies that colour trends seen among asteroids are most probably due to compositional or surface-particle-size properties, rather than to different relative ages, as well as demonstrating the necessity to take account of composition when evaluating weathering effectiveness.
Q-type asteroids: Possibility of non-fresh weathered surfaces
Itokawa particles, which are samples recovered from the S-complex asteroid 25143 Itokawa by the Hayabusa spacecraft, demonstrate that S-complex asteroids are parent bodies of ordinary chondrite
Distinctive space weathering on Vesta from regolith mixing processes
The surface of the asteroid Vesta has prominent near-infrared absorption bands characteristic of a range of pyroxenes, confirming a direct link to the basaltic howardite–eucrite–diogenite class of
The Formation and Evolution of Ordinary Chondrite Parent Bodies
Ordinary chondrites (OCs) are by far the most abundant meteorites (80% of all falls). Their origin has long been the matter of a heated debate. About thirty years ago (e.g., Pellas 1988), it was
Space Weathering on Airless Bodies.
TLDR
Volatile-rich bodies and those composed of abundant hydrous minerals (dwarf planet Ceres, many dark asteroids, outer solar system satellites) are affected by space weathering processes differently than the silicate bodies of the inner solar system.
Oxygen and Asteroids
Hundreds of thousands of asteroids have been discovered in the asteroid belt and in near-Earth space. Oxygen is an abundant element in meteorites and presumably in most asteroids. Spectral
Mineralogies and source regions of near-Earth asteroids
Abstract Near-Earth Asteroids (NEAs) offer insight into a size range of objects that are not easily observed in the main asteroid belt. Previous studies on the diversity of the NEA population have
Global mapping of the degree of space weathering on asteroid 25143 Itokawa by Hayabusa/AMICA observations
We obtained color images of near-Earth asteroid 25143 Itokawa by the Hayabusa multiband imaging camera to characterize the regional color properties. Images were obtained for the whole disk from the
Secondary submicrometer impact cratering on the surface of asteroid 25143 Itokawa
Abstract Particle RA-QD02-0265 returned by the Hayabusa spacecraft from near-Earth asteroid 25143 Itokawa displayed a unique abundance of submicrometer-sized (≤500 nm) impact craters, which are
Do Meteoroids Originating from Near-Earth Asteroid (25143) Itokawa Exist?
Making a survey of Itokawids, i.e., meteor(oid)s originating from Apollo-type near-Earth Asteroid (25143) Itokawa, from among the multiple-station optical meteor orbit data, and employing several

Space weathering from Mercury to the asteroid belt
The variety of evidence bearing on the nature of space weathering is reviewed. The effects of space weathering include spectral darkening, reddening and subdued absorption bands, and the distinctive
MUSES-C target asteroid (25143) 1998 SF36: A reddened ordinary chondrite
Abstract— Near-Earth asteroid (25143) 1998 SF36 is a planned target for the Japanese MUSES-C sample return mission. High signal-to-noise and relatively high-resolution (50 A) visible and
Mass and Local Topography Measurements of Itokawa by Hayabusa
TLDR
Combined with surface observations, these data indicate that Itokawa is the first subkilometer-sized small asteroid showing a rubble-pile body rather than a solid monolithic asteroid.
Near-Infrared Spectral Results of Asteroid Itokawa from the Hayabusa Spacecraft
TLDR
Spectral shape over the 1-micrometer absorption band indicates that the surface of asteroid 25143 Itokawa has an olivine-rich mineral assemblage potentially similar to that of LL5 or LL6 chondrites.

Detailed Images of Asteroid 25143 Itokawa from Hayabusa
TLDR
Rendezvous of the Japanese spacecraft Hayabusa with the near-Earth asteroid 25143 Itokawa took place during the interval September through November 2005 and the onboard camera imaged the solid surface of this tiny asteroid with a spatial resolution of 70 centimeters per pixel, revealing diverse surface morphologies.

TLDR
Evidence from Apollo 11 and Apollo 12 samples and telescopic spectral reflectivity measurements indicates that the maria are similar in mineralogy on a regional scale and that the highlands are consistent with an anorthositic-gabbro composition.
