NASA is sorting through a variety of possible uses for a pair of powerful spy satellite telescopes that fell into the agency's lap last year. <\/p>\n
In November, NASA asked scientists to suggest missions for the telescopes, which were donated by the U.S. National Reconnaissance Office (NRO) and are comparable in size and appearance to the famous Hubble Space Telescope. <\/p>\n
More than 60 serious proposals came flooding in, the most promising of which were presented in early February at the Study on Applications of Large Space Optics (SALSO) workshop in Huntsville, Ala. [Declassified U.S. Spy Satellites (Gallery)] <\/p>\n
\"There was a lot of excitement in the scientific community when these were transferred to NASA, because they are world-class, Hubble-class telescopes, optics,\" said SALSO project manager George Fletcher, of NASA's Marshall Space Flight Center in Huntsville. <\/p>\n
The two scopes were originallybuilt to carry out surveillance missions under a multibillion-dollar NRO program called Future Imagery Architecture. But cost overruns and delays killed the program in 2005, and NASA announced in June 2012 that the NRO had bequeathed the instruments to the space agency. <\/p>\n
While the telescopes' 8-foot-wide (2.4 meters) main mirrors are comparable to that of Hubble, the NRO instruments are designed to have a much wider field of view, NASA officials have said. <\/p>\n
Seven big ideas <\/p>\n
The ideas presented at the SALSO workshop fall into seven broad categories, meeting organizers and a technical review team determined: <\/p>\n
The SALSO workshop did not look into another possible use incorporating one of the NRO scopes into NASA's proposed $1.5 billion Wide-Field Infrared Survey Telescope, a high-priority mission that would hunt for exoplanets and probe the mysteries of dark energy because a separate research team is already investigating this possibility. <\/p>\n
The results of that second study, known as AFTA (Astrophysics Focused Telescope Assets), are expected any day now. Once AFTA is done, a more serious examination of the ideas presented at SALSO can begin. <\/p>\n
