Aquanaut
An aquanaut is any person who remains underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as saturation. Usually this is done in an underwater habitat on the seafloor for a period equal to or greater than 24 continuous hours without returning to the surface. The term is often restricted to scientists and academics, though there were a group of military aquanauts during the SEALAB program. Commercial divers in similar circumstances are referred to as saturation divers. An aquanaut is distinct from a submariner, in that a submariner is confined to a moving underwater vehicle such as a submarine that holds the water pressure out. Aquanaut derives from the Latin word ''aqua'' ("water") plus the Greek ''nautes'' ("sailor"), by analogy to the similar construction "astronaut". The first human aquanaut was Robert Sténuit, who spent 24 hours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NEEMO
NASA Extreme Environment Mission Operations, or NEEMO, is a NASA analog mission that sends groups of astronauts, engineers and scientists to live in the Aquarius (laboratory), Aquarius underwater laboratory, the world's only undersea research station, for up to three weeks at a time in preparation for future space exploration. Aquarius is an underwater habitat off Key Largo, Florida, in the Florida Keys National Marine Sanctuary. It is deployed on the ocean floor next to deep coral reefs below the surface. NASA has used it since 2001 for a series of space exploration simulation missions, usually lasting 7 to 14 days, with space research mainly conducted by international astronauts. The mission had cost about 500 million U.S. dollars. The crew members are called aquanauts (as they live underwater at depth pressure for a period equal to or greater than 24 continuous hours without returning to the surface), and they perform Extra-vehicular activity, EVAs in the underwater env ...

SEALAB
SEALAB I, II, and III were experimental underwater habitats developed by the United States Navy in the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of time. The knowledge gained from the SEALAB expeditions helped advance the science of deep sea diving and rescue, and contributed to the understanding of the psychological and physiological strains humans can endure. United States Navy Genesis Project Preliminary research work was undertaken by George F. Bond. Bond began investigations in 1957 to develop theories about saturation diving. Bond's team exposed rats, goats, monkeys, and human beings to various gas mixtures at different pressures. By 1963 they had collected enough data to test the first SEALAB habitat. SEALAB I SEALAB I was commanded by Captain Bond, who became known as "Papa Topside". SEALAB I proved that saturation diving in the open ocean was viable for extended periods. The experiment also offered info ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underwater Habitat
Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping. In this context, 'habitat' is generally used in a narrow sense to mean the interior and immediate exterior of the structure and its fixtures, but not its surrounding marine environment. Most early underwater habitats lacked regenerative systems for air, water, food, electricity, and other resources. However, some underwater habitats allow for these resources to be delivered using pipes, or generated within the habitat, rather than manually delivered. An underwater habitat has to meet the needs of human physiology and provide suitable environmental conditions, and the one which is most critical is breathing air of suitable quality. Others concern the physical environment (pressure, temperature, light, humidity), the chemical environment (drink ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Carpenter
Malcolm Scott Carpenter (May 1, 1925 – October 10, 2013) was an American naval officer and aviator, test pilot, aeronautical engineer, astronaut, and aquanaut. He was one of the Mercury Seven astronauts selected for NASA's Project Mercury in April 1959. Carpenter was the second American (after John Glenn) to orbit the Earth and the fourth American in space, after Alan Shepard, Gus Grissom, and Glenn. Commissioned into the U.S. Navy in 1949, Carpenter became a naval aviator, flying a Lockheed P-2 Neptune with Patrol Squadron 6 (VP-6) on reconnaissance and anti-submarine warfare missions along the coasts of Soviet Union and China during the Korean War and the Cold War. In 1954, he attended the U.S. Naval Test Pilot School at NAS Patuxent River, Maryland, and became a test pilot. In 1958, he was named Air Intelligence Officer of , which was then in dry dock at the Bremerton Navy Yard. The following year, Carpenter was selected as one of the Mercury Seven astronauts. He w ...

Robert Sheats
Robert Carlton Sheats (September 30, 1915 – March 9, 1995) was an American Master Diver in the United States Navy. He enlisted in the Navy in 1935 and retired in July 1966. Career World War II In 1941, while Sheats was serving as a First Class Diver aboard the submarine tender USS ''Canopus'' in the Philippines, the ship was severely damaged by Japanese planes during the Battle of Bataan. After the ship was scuttled, to prevent its capture by enemy forces, Sheats joined the ground forces defending Bataan and Corregidor. On May 6, 1942, Sheats and his men were captured and taken as prisoners of war. During his imprisonment at Bataan, Sheats and several members of his team were pressed into service as salvage divers by the Japanese to recover silver coins worth over $8 million (in 1942) that had been dumped by a U.S. Navy vessel between Manila Bay and the island of Corregidor when capture of the vessel by the Japanese was inevitable. He ensured that as few coins as possible we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People's Liberation Army Astronaut Corps astronauts and their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Sténuit
Robert Pierre André Sténuit (born 1933 in Brussels) is a Belgian journalist, writer, and underwater archeologist. In 1962 he spent 24 hours on the floor of the Mediterranean Sea in the submersible "Link Cylinder" developed by Edwin Link, thus becoming the world's first aquanaut. Early career Sténuit began spelunking at the age of seventeen. He discovered diving in 1953, when he began scuba diving in flooded caves in Belgium. He subsequently became interested in speleology, and went on to spend many years exploring the Caves of Han-sur-Lesse. Sténuit had a passion for history. At the age of 20, after reading ''600 Milliards Sous les Mers'' bHarry Reiseberg a work of fiction about shipwrecks and treasure diving, Sténuit left the Free University of Brussels, where he was studying political and diplomatic science in preparation for a career as a lawyer.
