An extremophile is an organism that is able to live in extreme environments, i.e. environments with conditions approaching or expanding the limits of what known life can adapt to, such as extreme temperature, radiation, salinity, or pH level.
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere. Measurements from Halley led to the discovery of the ozone hole in 1985. The current base is the sixth in a line of structures and includes design elements intended to overcome the challenge of building on a floating ice shelf without being buried and crushed by snow. As of 2020, the base has been left unstaffed through winter since 2017, due to concerns over the propagation of an ice crack and how this might cut off the evacuation route in an emergency. The Halley Bay Important Bird Area with its emperor penguin colony lies in the general vicinity of the base.
Jay Clark Buckey, Jr. is an American physician and astronaut who flew aboard one Space Shuttle mission (STS-90) as a Payload Specialist. Buckey briefly ran for the Democratic nomination to challenge New Hampshire Senator John E. Sununu, a first term Republican, when he was up for re-election in 2008. Buckey withdrew from the race when former Governor Jeanne Shaheen entered the race.
Dome C, also known as Dome Circe, Dome Charlie or Dome Concordia, located at Antarctica at an elevation of 3,233 metres (10,607 ft) above sea level, is one of several summits or "domes" of the Antarctic Ice Sheet. Dome C is located on the Antarctic Plateau, 1,100 kilometres (680 mi) inland from the French research station at Dumont D'Urville, 1,100 kilometres (680 mi) inland from the Australian Casey Station and 1,200 kilometres (750 mi) inland from the Italian Zucchelli station at Terra Nova Bay. Russia's Vostok Station is 560 kilometres (350 mi) away. Dome C is the site of the Concordia Research Station, jointly operated by France and Italy.
Concordia Research Station, which opened in 2005, is a French–Italian research facility that was built 3,233 m (10,607 ft) above sea level at a location called Dome C on the Antarctic Plateau, Antarctica. It is located 1,100 km (680 mi) inland from the French research station at Dumont D'Urville, 1,100 km (680 mi) inland from Australia's Casey Station and 1,200 km (750 mi) inland from the Italian Zucchelli Station at Terra Nova Bay. Russia's Vostok Station is 560 km (350 mi) away. The Geographic South Pole is 1,670 km (1,040 mi) away. The facility is also located within Australia's claim on Antarctica, the Australian Antarctic Territory.
Venturing into the environment of space can have negative effects on the human body. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton. Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells, balance disorders, eyesight disorders and changes in the immune system. Additional symptoms include fluid redistribution, loss of body mass, nasal congestion, sleep disturbance, and excess flatulence. Overall, NASA refers to the various deleterious effects of spaceflight on the human body by the acronym RIDGE.
Space medicine is the practice of medicine on astronauts in outer space whereas astronautical hygiene is the application of science and technology to the prevention or control of exposure to the hazards that may cause astronaut ill health. Both these sciences work together to ensure that astronauts work in a safe environment. The main objective is to discover how well and for how long people can survive the extreme conditions in space, and how fast they can adapt to the Earth's environment after returning from their voyage. Medical consequences such as possible blindness and bone loss have been associated with human spaceflight.
The MARS-500 mission was a psychosocial isolation experiment conducted between 2007 and 2011 by Russia, the European Space Agency, and China, in preparation for an unspecified future crewed spaceflight to the planet Mars. The experiment's facility was located at the Russian Academy of Sciences' Institute of Biomedical Problems (IBMP) in Moscow, Russia.
Ellsworth K. Eric Gunderson, Ph.D. was a psychologist who has studied human adaptation to living and working under the conditions associated with isolation and confinement. He is an important contributor to the field of Antarctic psychology.
Jessica Ulrika Meir is an American NASA astronaut, marine biologist, and physiologist. She was previously an assistant professor of anesthesia at Harvard Medical School, Massachusetts General Hospital, Boston, following postdoctoral research in comparative physiology at the University of British Columbia. She has studied the diving physiology and behavior of emperor penguins in Antarctica, and the physiology of bar-headed geese, which are able to migrate over the Himalayas. In September 2002, Meir served as an aquanaut on the NASA Extreme Environment Mission Operations 4 crew. In 2013, she was selected by NASA to Astronaut Group 21. In 2016, Meir participated in ESA CAVES, a training course in which international astronauts train in a space-analogue cave environment. Meir launched on September 25, 2019, to the ISS onboard Soyuz MS-15, where she served as a flight Engineer during Expedition 61 and 62. On October 18, 2019, Meir and Christina Koch were the first women to participate in an all-female spacewalk.
The winter-over syndrome is a condition that occurs in individuals who "winter-over" throughout the Antarctic winter, which can last seven to eight months. It has been observed in inhabitants of research stations in Antarctica, as well as in polar bases such as Thule, Alert and Eureka. It consists of a variety of behavioral and medical disturbances, including irritability, depression, insomnia, absentmindedness, aggressive behavior, and irritable bowel syndrome.
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) is an analog habitat for human spaceflight to Mars currently operated by the International MoonBase Alliance. HI-SEAS is located in an isolated position on the slopes of the Mauna Loa volcano on the island of Hawaii. The area has Mars-like features and an elevation of approximately 8,200 feet (2,500 m) above sea level. The first HI-SEAS study was in 2013 and NASA's Human Research Program continues to fund and sponsor follow-up studies. The missions are of extended duration from four months to a year. Its missions place HI-SEAS in the company of a small group of analogs that are capable of operating very long duration missions in isolated and confined environments, such as Mars500, Concordia, and the International Space Station.
Psychological and sociological effects of space flight are important to understanding how to successfully achieve the goals of long-duration expeditionary missions. Although robotic spacecraft have landed on Mars, plans have also been discussed for a human expedition, perhaps in the 2030s, or as early as 2024 for a return mission.
A Mars analog habitat is one of several historical, existing or proposed research stations designed to simulate the physical and psychological environment of a Martian exploration mission. These habitats are used to study the equipment and techniques that will be used to analyze the surface of Mars during a future crewed mission, and the simulated isolation of the volunteer inhabitants allows scientists to study the medical and psychosocial effects of long-term space missions. They are often constructed in support of extensive Mars analogs. However, sometimes existing natural places are also valued as Mars analogs. Crewed Mars habitats are featured in most human Mars missions; an alternative may be terraforming or telepresence.

Confined environment psychology is a refined subcategory of environmental psychology. There can be severe neurological impacts upon remaining in a confined environment over a prolonged period of time. Confined environment psychology can come in different forms, including; by location and lack of or limited human interaction. The broad subcategory also includes the effects of social isolation on animals.
