Beth E. Clark,Paul Helfenstein,James F. Bell,Christine Peterson,Joseph Veverka,N. I. Izenberg,Deborah L. Domingue,Dennis D. Wellnitz,Lucy A. McFadden +8 more
TL;DR: In this article, the authors present near-infrared spectrometer (NIS) observations of the S-type asteroid 433 Eros obtained by the NEAR Shoemaker spacecraft and report results of their Hapke photometric model analysis of data obtained at phase angles ranging from 1.2° to 111.0° and at spatial resolutions of 1.25×2.5 km/spectrum.

Asteroid surface materials - Mineralogical characterizations from reflectance spectra
TL;DR: In this paper, the spectral reflectance curves of the asteroids of the main asteroid belt are dominated by the presence of metallic nickel-iron in their surface materials and the C2-like materials which dominate the main belt population appear to be relatively rare on earth-approaching asteroids.

Albedo and color contrasts on asteroid surfaces
TL;DR: Asteroids in general display only small or negligible variations in spectrum or albedo during a rotational cycle as mentioned in this paper, and only 3 Juno, 4 Vesta, 6 Hebe, 71 Niobe, 349 Dembowka, and 944 Hidalgo display color variations larger than 0.03 mag.

TL;DR: In this article, the authors used multispectral imaging to characterize hemispheric and regional color properties of Eros and obtained the highest-resolution whole-disk data, 180 m/pixel, during the last pre-orbit insertion sequence on 12 February 2000.
Journal ArticleDOI
Mining the Apollo and Amor Asteroids
TL;DR: In this paper, the authors suggest that several new candidate asteroids will be discovered over the next few years, which increases the likelihood that a variety of asteroidal resource materials can be retrieved on low-energy missions.

Surface properties of asteroids - A synthesis of polarimetry, radiometry, and spectrophotometry
TL;DR: In this article, surface compositions of 110 asteroids are analyzed using data obtained by polarimetry and visible and near-IR spectrophotometry, and the results support the conclusions that asteroids and meteorites have similar classes of mineral assemblages.

Asteroids: Surface Composition from Reflection Spectroscopy
TL;DR: In this article, the spectral properties of 14 asteroids were determined by using asteroid reflectance spectra and optical properties of meteorites and other materials, and it was shown that the asteroid belt is a source of at least some meteoritic material.
