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 of, analysis, particles, reported and/or august:
“Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
—Octavio Paz (b. 1914)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
“O my countrymen!—be nice;Mbe cautious of your language;—and never, O! never let it be forgotten upon what small particles your eloquence and your fame depend.”
—Laurence Sterne (1713–1768)
“Strange new problems are being reported in the growing generations of children whose mothers were always there, driving them around, helping them with their homework—an inability to endure pain or discipline or pursue any self- sustained goal of any sort, a devastating boredom with life.”
—Betty Friedan (b. 1921)
“That night ended the day when history was written in Abilene. August 14, 1865 was the date. That was the end of the first drive on the Chisolm Trail. It was just the first of thousands of such drives bringing beef to the world.”
—Borden Chase [Frank Fowler] (1900–1971)
