Towards understanding the dynamical evolution of asteroid 25143 Itokawa: constraints from sample analysis
The data from the analysis of samples returned by Hayabusa from asteroid 25143 Itokawa are used to constrain the preaccretion history, the geological activity that occurred after accretion, and the dynamical history of the asteroid from the main belt to near-Earth space. We synthesize existing data to pose hypotheses to be tested by dynamical modeling and the analyses of future samples returned...

متن کاملThermal infrared observations of the Hayabusa spacecraft target asteroid 25143 Itokawa ⋆
We obtained N-and Q-band observations of the Apollo-type asteroid 25143 Itokawa during its close Earth approach in July 2004 with TIMMI2 at the ESO 3.6 m telescope. Our photometric measurement, in combination with already published data, allowed us to derive a radiometric effective diameter of 0.32±0.03 km and an albedo of 0.19 +0.11 −0.03 through a thermophysical model. This effective diameter...
