Canyon was a series of seven United States spy satellites launched between 1968 and 1977. Also known by its program number AFP-827, the satellites were developed with the participation of the Air Force. The Canyon project is credited as being the first American satellite system tasked for COMINT.

The satellites each had a mass of 700 kg and were launched from Atlas/Agena D rockets into near-geosynchronous orbits. They carried large parabolic reflecting dishes, estimated at 10m in diameter. The Canyon satellites were eventually replaced with the next generation of COMINT satellites, the Vortex/Chalet series. The program is still classified.

Seven Canyon satellites were launched from 1968 to 1977, all with Atlas Agena D vehicles from LC-13 at Cape Canaveral and there was one failure in 1971. The first four Canyons apparently remained attached to the Agena after achieving orbit, using its engine for maneuvering (the missions would have been concluded after Agena propellant depletion). Later Canyons were reputedly larger in size and did separate from the booster.

A canyon or gorge is a geographical feature.

Insomnia is a sleep disorder. People with insomnia have trouble sleeping: difficulty falling asleep, or staying asleep as long as desired. While the term is sometimes used to describe a disorder as diagnosed by polysomnographic or actigraphic evidence, this is often practically defined as a positive response to either of two questions: "do you experience difficulty sleeping?" or "do you have difficulty falling or staying asleep?"

Insomnia is most often thought of as both a medical sign and a symptom that can accompany several sleep, medical, and psychiatric disorders characterized by a persistent difficulty falling asleep and/or staying asleep or sleep of poor quality. Insomnia is typically followed by functional impairment while awake. Insomnia can occur at any age, but it is particularly common in the elderly. Insomnia can be short term (up to three weeks) or long term (above 3–4 weeks); it can lead to memory problems, depression, irritability and an increased risk of heart disease and automobile related accidents.

Deinonychus was a Dutch doom metal band formed in 1992 by Marco Kehren. There is a close relationship between Deinonychus and the German band Bethlehem: Kehren provided vocals on S.U.I.Z.I.D., Reflektionen auf's Sterben and Profane Fetmilch Lenzt Elf Krank, while Bethlehem bassist and lyricist Jürgen Bartsch joined Deinonychus in 2005. The first three albums and the early demos released as After the rain falls...an empty sky remains feature Kehren on all instruments and vocals; 1999's Deinonychus added Cradle of Filth drummer William Sarginson, and 2002's Mournument was recorded with a full band. The band announced that they disbanded in September 2008. Marco Kehren nowadays runs a martial industrial band by the name of Nihil Novi Sub Sole (Band). Warfare
