Human Space ExplorationMoon Base / Mars Exploration
• Challenging unexperienced risks• Using ISS for verification = ISS as a test‐bed

Mars Environmental Aspects for Human
• Limited Resources• Isolation• Hostile/closed environment spacecraft design
• Altered gravity• Space Radiation
![Page 13: Space Medicine and Satellite Technology “Tele Epidemiology” · lesser extent low Earth orbit, are protected by the Van Allen Belts, regions of trapped radiation held in place](https://reader034.vdocument.in/reader034/viewer/2022050204/5f57d6557842e8722e4fb609/html5/thumbnails/13.jpg)
Limited Resources
• “Storage, power, and weight limitations in the crafts in which humans will travel and live in deep space will affect the amount and type of food, medical supplies, exercise equipment, and other resources available.” NASA Office of Inspector General IG‐16‐003
![Page 14: Space Medicine and Satellite Technology “Tele Epidemiology” · lesser extent low Earth orbit, are protected by the Van Allen Belts, regions of trapped radiation held in place](https://reader034.vdocument.in/reader034/viewer/2022050204/5f57d6557842e8722e4fb609/html5/thumbnails/14.jpg)
Isolation• “Because crews will be millions of
of miles and many months travel from Earth, they must be prepared to deal with a variety of medical situations ranging from minor cuts to catastrophic injuries.In addition, isolation from Earth may case psychological and behavioral issues for crew members that could affect their wellbeing and performance. Finally, the periodic deliveries of supplies available to crews living on the ISS will not be an option in deep space.”

Hostile/Closed Environment Spacecraft Design
• “Spacecraft will have a closed life‐support system and cramped working and living quarters. The ISS has 15,000cubic feet of habitable area ‐ more than a conventional 3‐bedroom house. In contrast, the Orion crew capsule NASA is developing and plans to use for at least the initial forays beyond low Earth orbit has 314 cubic feet of habitable area.”

Altered Gravity• “The prolonged
weightlessness experienced in space causes astronauts to endure a number of physical and physiological changes. For example, astronauts routinely experience altered inner ear function as well as loss of bone density and muscle strength and blood and other body fluids move from the legs and lower extremities to the upper parts of the body.”

Space Radiation • “Deep space radiation is significantly
different from radiation encountered on Earth, and it is unknown how the human body will respond to prolonged exposure. Earth, and to a lesser extent low Earth orbit, are protected by the Van Allen Belts, regions of trapped radiation held in place by the Earth’s magnetic field that shield the planet and its human inhabitants from space radiation and solar weather. Missions that travel beyond low Earth orbit do not enjoy the protection of the Belts.”
