Reviews the planning, development, launching and function of the Orbiting Astronomical Observatory, a series of orbiting telescopes which are being used to study our solar system and the stars beyond. Features comments by the following leading scientists on the potential of this advancement in astronomy: Dr. Arthur Code, Wisconsin telescopes; Dr. James Kupperian, Goddard Flight Center using Cassegrain designs; Dr. Fred Whipple on the ultraviolet light sky mapping project; and Dr. Donald Morton on the Princeton OAO ultraviolet spectroscopy project.

The NIRSpec will be the first spectrograph in space that has this capability. Targets in the Field of View are normally selected by opening groups of shutters in a micro-shutter array (MSA) to form multiple apertures.NIRSpec will address all of the four main JWST science themes, and much more. It will enable large spectroscopic surveys of faint galaxies at high redshift, obtain sensitive spectra of transiting exoplanets and image line emission from protoplanetary disks and protostars. NIRSpec is being built for the European Space Agency (ESA) by the Airbus Group. || ", "hits": 22 }, { "id": 11428, "url": "https://svs.gsfc.nasa.gov/11428/", "result_type": "Produced Video", "release_date": "2013-12-03T12:00:00-05:00", "title": "Alien Atmospheres", "description": "Since the early 1990's, astronomers have known that extrasolar planets, or \"exoplanets,\" orbit stars light-years beyond our own solar system. Although most exoplanets are too distant to be directly imaged, detailed studies have been made of their size, composition, and even atmospheric makeup - but how? By observing periodic variations in the parent star's brightness and color, astronomers can indirectly determine an exoplanet's distance from its star, its size, and its mass. But to truly understand an exoplanet astronomers must study its atmosphere, and they do so by splitting apart the parent star's light during a planetary transit. || ", "hits": 328 }, { "id": 11339, "url": "https://svs.gsfc.nasa.gov/11339/", "result_type": "Produced Video", "release_date": "2013-09-30T12:00:00-04:00", "title": "Propylene on Titan", "description": "With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn's large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan's surface is far too cold for liquid water - instead, Titan's clouds, rain, and lakes consist of liquid hydrocarbons like methane and ethane (which exist as gases here on Earth). When these hydrocarbons evaporate and encounter ultraviolet radiation in Titan's upper atmosphere, some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propane.NASA's Voyager 1 spacecraft first revealed the presence of several species of atmospheric hydrocarbons when it flew by Titan in 1980, but one molecule was curiously missing - propylene, the main ingredient in plastic number 5. Now, thanks to NASA's Cassini spacecraft, scientists have detected propylene on Titan for the first time, solving a long-standing mystery about the solar system's most Earthlike moon. || ", "hits": 129 }, { "id": 20193, "url": "https://svs.gsfc.nasa.gov/20193/", "result_type": "Animation", "release_date": "2012-12-03T12:00:00-05:00", "title": "Curiosity Rover Shakes, Bakes, and Tastes Mars with SAM", "description": "NASA's Curiosity rover analyzed its first solid sample of Mars with a variety of instruments, including the Sample Analysis at Mars (SAM) instrument suite.
