The Mars Society is a nonprofit organization that advocates for human Mars exploration and colonization. It was founded by Robert Zubrin in 1998 and based on Zubrin's Mars Direct philosophy, which aims to make human mission to Mars as lightweight and feasible as possible. The Mars Society aims to generate interest in the Mars program by garnering support from the public and lobbying. Many Mars Society members and former members are influential in the wider spaceflight community, such as Buzz Aldrin and Elon Musk.

A life-support system is the combination of equipment that allows survival in an environment or situation that would not support that life in its absence. It is generally applied to systems supporting human life in situations where the outside environment is hostile, such as outer space or underwater, or medical situations where the health of the person is compromised to the extent that the risk of death would be high without the function of the equipment.
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as an aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all.
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.
The Flashline Mars Arctic Research Station (FMARS) is the first of two simulated Mars habitats located on Devon Island, Nunavut, Canada, which is owned and operated by the Mars Society. The station is a member of the EU-INTERACT, circumarctic network of currently 89 terrestrial field bases located in northern Europe, Russia, US, Canada, Greenland, Iceland, the Faroe Islands, and Scotland as well as stations in northern alpine areas.
Ebullism is the formation of gas bubbles in bodily fluids due to reduced environmental pressure, for example at high altitude. It occurs because a system of liquid and gas at equilibrium will see a net conversion of liquid to gas as pressure lowers; for example, liquids reach their boiling point at lower temperatures when the pressure on them is lowered.
Hubertus Strughold was a German-born physiologist, war criminal, and prominent medical researcher. Beginning in 1935 he served as chief of aeromedical research for Hermann Göring's Ministry of Aviation, holding this position throughout World War II. In 1947 he was brought to the United States as part of Operation Paperclip and went on to serve in a number of high-level scientific posts with the US Air Force and NASA.
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.
Michael Reed Barratt is an American physician and a NASA astronaut. Specializing in aerospace medicine, he served as a flight surgeon for NASA before his selection as an astronaut, and has played a role in developing NASA's space medicine programs for both the Shuttle-Mir Program and International Space Station. His first spaceflight was a long-duration mission to the International Space Station, as a flight engineer in the Expedition 19 and 20 crew. In March 2011, Barratt completed his second spaceflight as a crew member of STS-133.

Space neuroscience is the scientific study of the central nervous system (CNS) functions during spaceflight. Living systems can integrate the inputs from the senses to navigate in their environment and to coordinate posture, locomotion, and eye movements. Gravity has a fundamental role in controlling these functions. In weightlessness during spaceflight, integrating the sensory inputs and coordinating motor responses is harder to do because gravity is no longer sensed during free-fall. For example, the otolith organs of the vestibular system no longer signal head tilt relative to gravity when standing. However, they can still sense head translation during body motion. Ambiguities and changes in how the gravitational input is processed can lead to potential errors in perception, which affects spatial orientation and mental representation. Dysfunctions of the vestibular system are common during and immediately after spaceflight, such as space motion sickness in orbit and balance disorders after return to Earth.
It is inevitable that medical conditions of varying complexity, severity and emergency will occur during spaceflight missions with human participants. Different levels of care are required depending on the problem, available resources and time required to return to Earth.
Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself, while others are injuries that could have occurred on Earth's surface. A non-exhaustive list of these conditions and their probability of occurrence can be found in the following sources:
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.
James R. Kass is a Canadian physicist engaged in the field of human spaceflight.
The United States Air Force School of Aerospace Medicine (USAFSAM) is the United States Air Force (USAF) organization focused on education, research, and operational consultation in aerospace and operational medicine. USAFSAM was founded in 1918 to conduct research into the medical and physiologic domains related to human flight, and as a school for medical officers trained to support military aviation operations, later coined as flight surgeons. The school supported early military aviation from World War I through the evolution of aviation and into the modern era. USAFSAM conducted medical research and provided medical support for the initial US space operations beginning in 1947 through the establishment of NASA in 1958. After the creation of NASA, USAFSAM continued to actively support civilian and military manned space missions through clinical and physiologic research. USAFSAM is one of the oldest continually operating school for flight surgeons and other operational medical personnel of its kind in the world. USAFSAM is located in Dayton, Ohio at Wright-Patterson Air Force Base, and is part of the 711th Human Performance Wing and the Air Force Research Laboratory (AFRL).
