Impact-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 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 کاملNEAR Magnetic Field Observations at 433 Eros: First Measurementsfrom the Surface of an Asteroid
The magnetometer investigation aboard the NEAR-Shoemaker spacecraft has obtained extensive magnetic field observations throughout the 433 Eros environment, from distances in excess of 100,000 km to those conducted after landing on 12 February 2001. We report the apparent absence of global scale magnetization at this asteroid (H < 0.005 A · m−1; natural remanent magnetization per kilogram < 1.9 ...
متن کاملNEAR Laser Rangefinder: A Tool for the Mapping and Topologic Study of Asteroid 433 Eros
n 1999, after a 3-year transit through space, the Near Earth Asteroid Rendezvous (NEAR) spacecraft will place a scientific payload consisting of five instruments into a low-altitude orbit (≈35 km) about the asteroid 433 Eros for 1 year. One instrument, the NEAR Laser Rangefinder (NLR), will use infrared laser pulses to provide astrophysicists with precision altimetry data, measurements that wer...
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...
