Minor element evidence that Asteroid 433 Eros is a space-weathered ordinary chondrite parent body
The NEAR mission to 433 Eros provided detailed data on the geology, mineralogy, and chemistry of this S-class asteroid [McCoy, T.J., Robinson, M.S., Nittler, L.R., Burbine, T.H., 2002. Chem. Erde 62, 89–121; Cheng, A.F., 1997. Space Sci. Rev. 82, 3–29] with a key science goal of understanding the relationship between asteroids and meteorites [Cheng, A.F., 1997. Space Sci. Rev. 82, 3–29; Gaffey,...
متن کاملThe 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...
متن کاملThrust faults and the near‐surface strength of asteroid 433 Eros
[1] NEAR Shoemaker images reveal widespread occurrence of tectonic landforms on asteroid 433 Eros. Hinks Dorsum is a ridge that extends for about 18 km around the asteroid and strongly resembles thrust fault structures on the terrestrial planets. Tectonic landforms can provide information on the mechanical properties of asteroids, a subject of much controversy. Modeling constrained by topograph...
متن کاملImpact-induced seismic activity on asteroid 433 Eros: a surface modification process.
High-resolution images of the surface of asteroid 433 Eros revealed evidence of downslope movement of a loose regolith layer, as well as the degradation and erasure of small impact craters (less than approximately 100 meters in diameter). One hypothesis to explain these observations is seismic reverberation after impact events. We used a combination of seismic and geomorphic modeling to analyze...
متن کاملThe 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...
