Lunar and Other Extraterrestrial Observations
In 2009, India's Chandrayaan-1 satellite, NASA's Cassini spacecraft and the Deep Impact probe have each detected the presence of water by evidence of hydroxyl fragments on the Moon. As reported by Richard Kerr, "A spectrometer (the Moon Mineralogy Mapper, aka "M3"), detected an infrared absorption at a wavelength of 3.0 micrometers that only water or hydroxyl–a hydrogen and an oxygen bound together–could have created." NASA also reported in 2009 that the LCROSS probe revealed an ultraviolet emission spectrum consistent with hydroxyl presence. The Venus Express orbiter has been continuously sending back Venus science data since April 11, 2006. Results from Venus Express include the detection of hydroxyl in the atmosphere.

Famous quotes containing the words lunar and/or observations:
“A bird half wakened in the lunar noon
Sang halfway through its little inborn tune.”
—Robert Frost (1874–1963)
“Jerry: She’s one of those third-year girls that gripe my liver.
Milo: Third-year girls?
Jerry: Yeah, you know, American college kids. They come over here to take their third year and lap up a little culture. They give me a swift pain.
Milo: Why?
Jerry: They’re officious and dull. They’re always making profound observations they’ve overheard.”
—Alan Jay Lerner (1918–1986)
