Advances in the discovery and characterization of asteroids over the past decade have
revealed an unanticipated underlying structure that points to a dramatic early history of the …

▪ Abstract Visible and near-infrared spectra of reflected sunlight from asteroid surfaces
exhibit features that hold the promise for identifying surface mineralogy. However, the very …

The Hayabusa spacecraft successfully recovered dust particles from the surface of near-
Earth asteroid 25143 Itokawa. Synchrotron-radiation x-ray diffraction and transmission and …

Advancing technology in near-infrared instrumentation and dedicated planetary telescope
facilities have enabled nearly two decades of reconnoitering the spectral properties for near …

During the interval from September through early December 2005, the Hayabusa spacecraft
was in close proximity to near-Earth asteroid 25143 Itokawa, and a variety of data were …

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 …

Abstract The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith
Explorer (OSIRIS-REx) spacecraft mission characterized and collected a sample from …

We present new visible and near-infrared spectroscopic measurements for 252 near-Earth
(NEO) and Mars-crossing (MC) objects observed from 1994 through 2002 as a complement …

In this work we identify spectral similarities between asteroids and meteorites. Using spectral
features such as absorption bands and spectral curvature, we identify spectral matches …

Rendezvous of the Japanese spacecraft Hayabusa with the near-Earth asteroid 25143
Itokawa took place during the interval September through November 2005. The onboard …
