High Resolution Imaging Science Experiment is a camera on board the Mars Reconnaissance Orbiter. The 65 kg (143 lb), $40 million USD instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5 m (19.7 in) aperture reflecting telescope, the largest so far of any deep space mission, which allows it to take pictures of Mars with resolutions of 0.3 m/pixel (about 1 foot), resolving objects below a meter across.
HiRISE has imaged Mars landers on the surface, including the ongoing Curiosity<ref name=HiRISE Operations Center. (2012, September 29). hirise images of msl (curiosity).

History
In the late 1980s, Alan Delamere of Ball Aerospace began planning the kind of high-resolution imaging needed to support sample return and surface exploration of Mars. In early 2001 he teamed up with Alfred McEwen of the University of Arizona to propose such a camera for the Mars Reconnaissance Orbiter (MRO), and NASA formally accepted it November 9, 2001.
Fil
FIL or Fil may refer to:
Filmjölk
Filmjölk (also known as fil) is a Nordic dairy product made from soured milk. It is similar to yogurt, but is produced using different bacteria and cultured at a lower temperature than yogurt, which gives it a different taste and texture. It is the modern version of the traditional product surmjölk (sour milk).
It is a mesophilic fermented milk product that is made by fermenting cow's milk with a variety of bacteria from the species Lactococcus lactis and Leuconostoc mesenteroides. The bacteria metabolize lactose, the sugar naturally found in milk, into lactic acid which means people who are lactose intolerant can tolerate it better than other dairy products. The acid gives filmjölk a sour taste and causes proteins in the milk, mainly casein, to coagulate, thus thickening the final product. The bacteria also produce a limited amount of diacetyl, which gives filmjölk its characteristic taste. Filmjölk is similar to cultured buttermilk, kefir, or yogurt in consistency, but has a different taste and texture. Its taste is mild and slightly acidic. In Sweden, it is normally sold in 1-liter packages with live bacteria. It has a shelf-life of around 10–14 days at refrigeration temperature.
Fili
A fili was a member of an elite class of poets in Ireland, up until the Renaissance, when the Irish class system was dismantled by the English.
Etymology
The word "file" is thought to derive from the Proto-Celtic *widluios, meaning "seer, one who sees" (attested on the Gaulish inscription from Larzac as "uidluias", which is the feminine genitive singular form), derived ultimately from the verb *widlu-, "to see". This may suggest that the filí were originally prophetic poets, who foretold the future in the form of verse or riddle, rather than simply poets.
Elite scholars
According to the Textbook of Irish Literature, by Eleanor Hull:
Oral tradition
The fili maintained an oral tradition that predated the Christianization of Ireland. In this tradition, poetic and musical forms are important not only for aesthetics, but also for their mnemonic value. The tradition allowed plenty of room for improvisation and personal expression, especially in regard to creative hyperbole and clever kenning. However, the culture placed great importance on the fili's ability to pass stories and information down through the generations without making changes in those elements that were considered factual rather than embellishment.
