Later Surveys
Several space infrared telescopes have continued and greatly expanded the study of the infrared Universe, such as the Infrared Space Observatory launched in 1995, the Spitzer Space Telescope launched in 2003, and the AKARI Space Telescope launched in 2006.
A next generation of infrared space telescopes began when NASA's Wide-field Infrared Survey Explorer launched December 14, 2009 aboard a Delta II rocket from Vandenberg Air Force Base in California. Known as WISE, the telescope provided results hundreds of times more sensitive than IRAS at the shorter wavelengths, and also had an extended mission into 2011 even after its coolant supply ran out.

Famous quotes containing the word surveys:
“Linnæus, setting out for Lapland, surveys his “comb” and “spare shirt,” “leathern breeches” and “gauze cap to keep off gnats,” with as much complacency as Bonaparte a park of artillery for the Russian campaign. The quiet bravery of the man is admirable.”
—Henry David Thoreau (1817–1862)
“The three main medieval points of view regarding universals are designated by historians as realism, conceptualism, and nominalism. Essentially these same three doctrines reappear in twentieth-century surveys of the philosophy of mathematics under the new names logicism, intuitionism, and formalism.”
—Willard Van Orman Quine (b. 1908)
