Comparative laboratory study of materials returned to Earth from the Itokawa asteroid with particles collected in the stratosphere
نویسنده
چکیده
Description: Samples from extra-terrestrial objects that are available for detailed investigation in the laboratory are particularly important to advance our understanding of the formation and evolution of our solar system, where sophisticated instrumentation can be deployed to unlock the secrets they contain. The most primitive and pristine materials are the most useful, but also the rarest samples. Such material falling to Earth as meteorites and dust is readily destroyed or modified during atmospheric entry, and that which does survive to the surface of Earth rapidly reacts with the terrestrial environment. Samples collected in space and returned by spacecraft offer the best opportunity to identify and study the most primitive materials from the earliest stages of solar system formation.

Oxygen isotopic compositions of asteroidal materials returned from Itokawa by the Hayabusa mission.
Meteorite studies suggest that each solar system object has a unique oxygen isotopic composition. Chondrites, the most primitive of meteorites, have been believed to be derived from asteroids, but oxygen isotopic compositions of asteroids themselves have not been established. We measured, using secondary ion mass spectrometry, oxygen isotopic compositions of rock particles from asteroid 25143 I...
متن کاملTowards 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 کاملAdvanced robotic system of hopping rovers for small solar system bodies
Japan has announced the official development of “Hayabusa-2”, the second sample return mission to a Near-Earth asteroid. When the development is made smoothly, Hayabusa-2 will be launched in 2014. The predecessor spacecraft “Hayabusa” made a great success when it returned to the Earth in June 2010 with a capsule containing some particles obtained from S-type asteroid “Itokawa.” The authors inst...

متن کاملGranular Mechanics in Asteroid Regolith: Simulating and Scaling the Brazil Nut Effect
Introduction It is well known that shaking can drive size sorting and segregation in granular media ( [1] and references therein). We consider the hypothesis that seismic shaking on asteroids could promote the size sorting of its constituent particles [2]. Such sorting is evident in the images sent by the Hayabusa mission of the surface of the asteroid Itokawa [3]. The simplest example of this ...
