The spin state of 433 Eros and its possible implications

In this paper, we show that Asteroid (433) Eros is currently residing in a spin–orbit resonance, with its spin axis undergoing a smallamplitude libration about the Cassini state 2 of the proper mode in the nonsingular orbital element sin I/2 exp(ıΩ), where I the orbital inclination and Ω the longitude of the node. The period of this libration is 53.4 kyr. By excluding these libration wiggles, w...

Spectral properties and rotational spectral heterogeneity of 433 Eros

Composite spectra of different rotational aspects of the S asteroid 433 Eros were assembled from previous studies, covering the wavelength range 0ø33-2.5 grn. These data allow us to measure significant attributes of Eros's spectrum• its mafic mineral absorptions, and the degree and nature of compositional heterogeneity of its surfaceo We also evaluated previous Sasteroid taxonomies using indepe...

The Orbital Dynamics Environment of 433 Eros: A Case Study for Future Asteroid Missions

The Near-Earth Asteroid Rendezvous (NEAR)–Shoemaker mission was a milestone in that it represented the practical navigation of a spacecraft in the most severely perturbed orbital environment (relative to the standard two-body problem) ever experienced by a spacecraft. Furthermore, all future asteroid orbital missions will encounter environments similar, in some way, to the environment encounter...

Elemental Composition from Gamma-ray Spectroscopy of the Near-shoemaker Landing Site on 433 Eros

Elemental composition and composition ratios derived from gamma-ray measurements collected by the NEAR-Shoemaker spacecraft while on the surface of 433 Eros are reported. Performance of the gamma-ray spectrometer (GRS) during cruise and orbit is reviewed. The best gamma-ray data were collected on the surface of Eros after the spacecraft’s controlled descent on 12 February 2001. Methods used in ...
