H.A.P.M.O.S.
Stories of Human Adaptation
Psychological and Physiological Alterations
in Isolated, Confined, and Extreme (ICE) Environments
H.A.P.M.O.S. (Human Adaptation Procedures and Measurements for Operational Solutions) is an ongoing NeurAstra project under the umbrella of the Blue Dot/White Tangerine and Specteore systems. It is dedicated to advancing our understanding of human behaviour, performance, and physical health in Isolated, Confined, and Extreme (ICE) environments.
ICE environments are Earth-based settings that allow us to simulate the conditions space travellers (STs) face during space missions. Isolation implies environments with limited contact with the outside world; confinement often involves living and working in small, enclosed spaces, mimicking the confined quarters of spacecraft and space habitats; while extreme environments include challenging conditions, extreme temperatures, limited resources, and harsh landscapes. Taken together, these three factors have proved to be valuable conditions for studying the physical, psychological, and operational burdens associated with living and working in space.
H.A.P.M.O.S. is designed around three distinctive phases. PHASE I. is thought to define and categorise the different environmental characteristics and their respective challenges to understand the context of ICE environment research. PHASE II. proposes a set of complementary experiments and procedures to measure physiological and psychological alterations. Ultimately, PHASE III. will take inspiration from the results to build operational solutions.

ICE ENVIRONMENTS SETTINGS (EARTH-BASED ANALOGUES)
Space analogue sites provide a controlled setting to study the effects of isolation, confinement, and other space-related factors on human health and performance. They also share several features with natural sites used in astrobiology research, which, while relevant, are outside of our experiments’ scope.
For more details about these analogue sites, see the planetary field analogues map annex.
H.A.P.M.O.S. studies rely mainly on the following sites/settings:
- POLAR EXPEDITIONS

research focus: long-term psychological and physical effects of space travel, team dynamics, mission planning and execution, and life support systems.
THE SPACE EXPOSOME CONCEPT
Exposome is a term used in environmental health and epidemiology to describe the totality of environmental exposures that an individual experiences over their lifetime, from conception to death. This includes not only traditional environmental factors like air pollution, diet, and chemicals but also psychosocial and lifestyle factors. In the context of space exploration, space exposome can refer to the complete set of environmental exposures and stressors that STs encounter throughout their missions, from pre-flight preparations to their time in space and their return to Earth. NASA’s Human Research Program coined the term RIDGE to pinpoint the five major stressors/hazards STs will encounter on their journey.
RIDGE: Radiation, Isolation and confinement, Distance from Earth, Gravity fields, hostile and closed Environments
- RADIATION
Outside Earth’s protective magnetic field and atmosphere, ionising radiation in space poses a serious risk to STs during deep-space missions. High-energy galactic cosmic rays, remnants from supernovas, and solar storms, like solar particle events and coronal mass ejections, can harm the body and spacecraft and have potential long-term health consequences.
Although astronauts and cosmonauts aboard the International Space Station (ISS) are exposed to higher levels of radiation than people on Earth, several factors limit however their impact. Indeed, the ISS orbits at an altitude of approximately 400 kilometres (about 250 miles) above the Earth, which is still within the protective layers of the Earth’s atmosphere and magnetosphere which provide significant protection against solar and cosmic radiation. The magnetosphere deflects and traps many of the high-energy particles from the sun and cosmic rays, reducing the amount of radiation that reaches the ISS. Secondly, the ISS itself is designed with shielding materials that help protect the crew from radiation. The modules are constructed using materials that can absorb and deflect radiation, and certain areas of the ISS offer more protection where astronauts can go during periods of increased solar activity. Finally, while the ISS provides some protection, the duration of exposure is also a factor. Most astronauts/cosmonauts spend about six months on the ISS, which limits their total radiation dose compared to more extended missions or those travelling beyond low Earth orbit.
- ISOLATION & CONFINEMENT
The psychological stress of long-duration space missions, coupled with confinement to a small spacecraft, can have significant mental health implications. Expedition crews selected for a stay onboard the space station are carefully chosen, trained, and supported to ensure they will be able to work effectively as a team for the duration of their six to 12-month missions. Crews for a Moon or Mars mission will undergo even more careful assessment, selection, and preparation since they will travel farther and potentially for longer than previous humans in an isolated and confined environment, with only a few other people. Additionally, crews will likely be international and multi-cultural, making cross-cultural sensitivity and team dynamics paramount to mission success.
- DISTANCE FROM EARTH
The space station orbits around 400 km (240 miles) above Earth. The Moon is 1,000 times farther from Earth than the space station. In contrast, Mars is, on average, 225 million kilometres (140 million miles) from Earth. With a communication delay of up to 20 minutes one-way while on Mars, STs must be able to solve problems and identify solutions as a team without help from their mission control. The types of food and medicine to be packed for a multi-year trip without access to a grocery store or pharmacy are also essential to consider. Unlike space station crews, which regularly receive supplies from cargo flights from Earth, STs going to Mars will have to bring all of the food, equipment, and medical supplies they need.
- ALTERED GRAVITY FIELDS (/MICROGRAVITY)
STs are exposed to a unique gravitational environment in space which can impact various physiological systems in the human body and induce several health outcomes, such as muscle and bone loss, cardiovascular changes, and fluid redistribution. On a Mars mission, STs will encounter three different gravity fields. On the six-month trek between the planets, crews will be weightless. While living and working on Mars, crews will be in approximately one-third of Earth’s gravity. Finally, upon returning home, crews will have to readapt to Earth’s gravity. Transitioning from one gravity field to another is not as easy as it seems. It affects spatial orientation, head-eye and hand-eye coordination, balance, and locomotion, and some crew members can experience space motion sickness (SMS). Landing a spacecraft on Mars, for instance, could be challenging as STs adjust to the gravity field of another celestial body. In addition, when shifting from weightlessness to gravity, STs may experience post-flight orthostatic intolerance, where they are unable to maintain their blood pressure when standing up, which can lead to lightheadedness and fainting.
- HOSTILE & CLOSED ENVIRONMENTS
The ecosystem inside the spacecraft plays a big role in everyday life in space. Microbes can change characteristics in space, and micro-organisms that naturally live on the human body are transferred more easily from person to person in closed habitats, such as the space station. Stress hormone levels are elevated and the immune system is altered, which could lead to increased susceptibility to allergies or other illnesses. Earth-based analogues do not perfectly simulate the spaceflight environment, making them insufficient for studying on the ground how human immune systems react in space. However, analogue studies could provide insight into how certain spaceflight stressors may affect the human immune system.
Further Readings:
Understanding the space exposome is consequently crucial as it allows space agencies and researchers to identify potential health risks and develop strategies to mitigate them. This can involve developing better shielding from radiation, designing spacecraft that minimise noise and vibration, optimising exercise routines, and proposing specific methodologies to address mental health issues remotely. Additionally, understanding the space exposome can inform the selection and training of STs, as individuals with specific attributes and coping mechanisms may be better suited to the challenges of space travel. H.A.P.M.O.S. projects focus on the following risk factors: 1. Isolation & Confinement, 2. Distance from Earth, and 3. Hostile & Closed Environments because of their feasibility and replicability in ICE environments.
