Analysis of Particles Reported in August 2011
The 26 August 2011, issue of Science devoted six articles to findings based on dust that Hayabusa had collected from Itokawa. Scientists' analysis suggested that Itokawa was probably made up from interior fragments of a larger asteroid that broke apart. Dust collected from the asteroid surface was believed to have been exposed there for about eight million years.
Scientists used varied techniques of chemistry and mineralogy to analyze the dust from Itokawa. Itokawa's composition was found to match the common type of meteorites known as "low-total-iron, low metal ordinary chondrites". Another team of scientists determined that the dark iron color on the surface of Itokawa was the result of abrasion by micrometeoroids and high-speed particles from the sun which had converted the normally whitish iron oxide coloring.

Famous quotes containing the words analysis, particles, reported and/or august:
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
“The atoms of Democritus
And Newton’s particles of light
Are sands upon the Red Sea shore,
Where Israel’s tents do shine so bright.”
—William Blake (1757–1827)
“The few who can talk like a book, they only get reported commonly. But this writer reports a new lieferung.”
—Henry David Thoreau (1817–1862)
“The aim of every political association is the preservation of the natural and imprescriptible rights of man. These rights are liberty, property, security and resistance to oppression.”
—French National Assembly. Declaration of the Rights of Man (drafted and discussed August 1789, published September 1791)
