Solifugae

Families
See text.

A Solifugid (plural form Solifugae) is an arachnid belonging to the order Solifugae, latin for They flee from the sun. The order is also known by the names Solpugida, Solifugae, Solpugides, Solpugae, Galeodea, and Mycetophorae. The order includes 900 known species, whose common names include "windscorpion", "sun spider", and "camel spider".

Most solifugae live in tropical or semitropical regions where they inhabit warm and arid habitats, but some species have been known to live in grassland or forest habitats. The most distinctive feature of solifugae is their large chelicerae. Each of the two chelicerae are composed of two articles forming a powerful pincer; each article bears a variable number of teeth. Males in all families but Eremobatidae possess a flagellum on the basal article of the chelicera. Solifugae also have long pedipalps, which function as sense organs similar to insects' antennae. Pedipalps terminate in eversible adhesive organs.

Solifugae are carnivorous or omnivorous, with most species feeding on termites, darkling beetles, and other small arthropods. Prey is located with the pedipalps and killed and cut into pieces by the chelicerae. The prey is then liquified and the liquid ingested through the pharynx. Reproduction can involve direct or indirect sperm transfer; when indirect, the male emits a spermatophore on the ground and then inserts it with his chelicerae in the female's genital pore.

As indicated by their name, Solifugae are mostly nocturnal, and seek shade during the day. It is this behavior which led coalition soldiers in the 2003 invasion of Iraq to think these arachnids were attacking them. In reality, they were merely moving toward the newly available shade provided by the soldiers' presence. The absence of shade sends them away.

Myths

Solifugae are the subject of many myths and exaggerations about their size, speed, behavior, appetite, and lethality. They are not especially large, the biggest having a legspan of perhaps 5 inches, and although they are fast on land compared to other invertebrates, the fastest can run perhaps 10 miles per hour, a common running speed for many humans. Members of this order of Arachnidae have no venom and do not spin webs. In the Middle East, it is common belief among American soldiers stationed there that Solifugae will feed on living human flesh. The story goes that the creature will inject some anesthetizing venom into the exposed skin of its sleeping victim, then feed voraciously, leaving the victim to awaken with a gaping wound. Solifugae, however, do not produce such an anesthetic, and, like most creatures with any sort of survival instinct, they do not attack prey larger than themselves unless they feel they must, such as situations of defense or protection of young. Due to their bizarre appearance and the fact that they produce a hissing sound when they feel threatened, many people are startled or even afraid of them. However, the greatest threat they pose to humans is their bite in self-defense when one tries to handle them. There is no chance of death directly caused by the bite, but, due to the strong muscles of their chelicerae, they can produce a proportionately large, ragged wound which is prone to infection. While one species, Rhagodes nigrocinctus, does appear to possess venom, its bite is not known to be dangerous to humans.

There are thirteen families belonging to the order Solifugae:. Such was the case with the winning team Scaled Composites, whose founder Burt Rutan announced in 1996 that the company would compete for the X Prize but worked entirely in secret for seven years, finally revealing the completed vehicle in April 2003. While one species, Rhagodes nigrocinctus, does appear to possess venom, its bite is not known to be dangerous to humans. Some companies developed their craft in secret, not publicly announcing their plans until they were ready to request air/space permission from their local government. There is no chance of death directly caused by the bite, but, due to the strong muscles of their chelicerae, they can produce a proportionately large, ragged wound which is prone to infection. Louis, Missouri), maintains a list of organizations registered to compete for the prize. However, the greatest threat they pose to humans is their bite in self-defense when one tries to handle them.

Due to their bizarre appearance and the fact that they produce a hissing sound when they feel threatened, many people are startled or even afraid of them. The X PRIZE Foundation, (based at the St. Solifugae, however, do not produce such an anesthetic, and, like most creatures with any sort of survival instinct, they do not attack prey larger than themselves unless they feel they must, such as situations of defense or protection of young. Created in May 1996 and initially called just "X Prize", it was renamed "Ansari X Prize" on May 6, 2004 following a multimillion dollar donation from Iranian-born entrepreneurs Anousheh Ansari and Amir Ansari. The story goes that the creature will inject some anesthetizing venom into the exposed skin of its sleeping victim, then feed voraciously, leaving the victim to awaken with a gaping wound. Although only the Tier One team actually launched a spacecraft into suborbital space, several other teams have conducted low-altitude tests or announced future plans to launch into space:. In the Middle East, it is common belief among American soldiers stationed there that Solifugae will feed on living human flesh. The trophy is currently on display in the lobby of the Science Fiction Museum in Seattle, Washington.

Members of this order of Arachnidae have no venom and do not spin webs. (Note: the winning team is referred to by several names at various times: Tier One, Scaled Composites, and Mojave Aerospace Ventures.). They are not especially large, the biggest having a legspan of perhaps 5 inches, and although they are fast on land compared to other invertebrates, the fastest can run perhaps 10 miles per hour, a common running speed for many humans. They thus won the prize, which was awarded on November 6, 2004. Solifugae are the subject of many myths and exaggerations about their size, speed, behavior, appetite, and lethality. The Tier One project made two successful competitive flights, X1 on September 29, 2004 and X2 on October 4, 2004. The absence of shade sends them away. However, the X Prize Foundation itself did not ban these companies from applying, so long as they could prove their efforts on this project would be free of government funding.

In reality, they were merely moving toward the newly available shade provided by the soldiers' presence. government agencies. It is this behavior which led coalition soldiers in the 2003 invasion of Iraq to think these arachnids were attacking them. These critics claim as evidence the companies' several failed attempts to do so, such as the X-33 project, on contract from NASA and other U.S. As indicated by their name, Solifugae are mostly nocturnal, and seek shade during the day. This contestant list notably did not include traditional space access companies like Boeing and Lockheed, which many in the industry believe to be incapable of replacing their present space transportation vehicles with low-cost alternatives. Reproduction can involve direct or indirect sperm transfer; when indirect, the male emits a spermatophore on the ground and then inserts it with his chelicerae in the female's genital pore. Twenty-six teams from around the world participated, ranging from volunteer hobbyists to large corporate-backed operations:.

The prey is then liquified and the liquid ingested through the pharynx. NASA is developing similar prize programs called Centennial Challenges to generate innovative solutions to space technology problems. Prey is located with the pedipalps and killed and cut into pieces by the chelicerae. The X Prize was modeled after many prizes from the early 20th century that helped prod the development of air flight, including notably the $25,000 Orteig Prize that spurred Charles Lindbergh to make his solo flight across the Atlantic Ocean. Solifugae are carnivorous or omnivorous, with most species feeding on termites, darkling beetles, and other small arthropods. If everything goes as planned, the X Prize winners could become pioneers of low-cost space travel and unfettered human expansion into the solar system. Pedipalps terminate in eversible adhesive organs. It is also hoped that competition will breed innovation, introducing new low-cost methods of reaching Earth orbit.

Solifugae also have long pedipalps, which function as sense organs similar to insects' antennae. It aimed to demonstrate that spaceflight can be affordable and accessible to corporations and civilians, opening the door to commercial spaceflight and space tourism. Males in all families but Eremobatidae possess a flagellum on the basal article of the chelicera. The X Prize was designed to help encourage the space industry in the private sector, which is why the entries were not allowed to have any government funding. Each of the two chelicerae are composed of two articles forming a powerful pincer; each article bears a variable number of teeth. Private sponsors were acceptable, however. The most distinctive feature of solifugae is their large chelicerae. Teams were forbidden to accept government funding for their efforts.

Most solifugae live in tropical or semitropical regions where they inhabit warm and arid habitats, but some species have been known to live in grassland or forest habitats. Official altitudes were determined by a compromise between the three systems. The order includes 900 known species, whose common names include "windscorpion", "sun spider", and "camel spider". There was a flight recorder, referred to as the "gold box", carried on each competitive flight, and two separate radar systems were used. The order is also known by the names Solpugida, Solifugae, Solpugides, Solpugae, Galeodea, and Mycetophorae. Altitudes achieved were measured by three separate systems. A Solifugid (plural form Solifugae) is an arachnid belonging to the order Solifugae, latin for They flee from the sun. The vehicle must be intact and theoretically reusable after the second flight, and the crew must return unharmed.

Solpugidae. Even NASA's Space Shuttle falls short of this performance requirement, since it takes much more than two weeks to ready a given shuttle between flights. Rhagodidae. With the exception of propellant, no more than 10% of the vehicle could be replaced between flights; the rest of the vehicle must be reused. Mummuciidae. The two competitive flights were required to be made by the same vehicle. Melanoblossidae. The 100 km target is the boundary of space as defined by the Fédération Aéronautique Internationale.

Karschiidae. The spacecraft were permitted to land at the same site that they launched from. Karschiidae. Reaching orbit was not a goal, and so all the competitors aimed to make suborbital flights only. Hexisopodidae. The contest winner was to be the first team to launch a piloted spacecraft, carrying at least three crewmembers (or one human pilot and payload equivalent to two more), to an altitude of at least 100 kilometers (328,100 ft or 62.14 mi), and then repeat the feat using the same spacecraft within two weeks. Gylippidae. .

Galeodidae. The prize was won on October 4, 2004, 47th anniversary of the Sputnik 1 launch, by the Tier One project using the experimental spaceplane SpaceShipOne. Eremobatidae. It was modelled after early 20th-century aviation prizes, and aimed to spur development of low-cost spaceflight. Daesiidae. The Ansari X Prize (formerly the X Prize) was a US$10,000,000 prize, offered by the X PRIZE Foundation, for the first non-government organization to launch a reusable manned spacecraft into space twice within two weeks.

On February 15, 2005, AERA (Formerly American Astronautics) announced its plans to send seven paying passengers into space as early as 2006, a full year before the first Virgin Galactic flight. On August 8, 2004, Space Transport Corporation's Rubicon 1 and Armadillo Aerospace's test vehicle, in two separate unmanned test launches, both crashed and were destroyed. The Canadian Arrow team conducted a successful full-power engine test in 2005 and announced on June 2, 2005, that it had received permission from the Canadian government to use Cape Rich as a future launch site. They have not announced a revised timetable.
