Abstract
Space medicine is an essential medical discipline that focuses on safe and healthy human space travel by incorporating medical information and practices from a number of relevant medical specialties to address the challenges and hazards of human spaceflight. With increasing global space activities, there is a growing demand for trained professionals in this field. We propose a cascade of educational and training programs: A short course (2–4 weeks) about space medicine, its roles, its accomplishments, and recommendations for further education; postgraduate diploma (6 months) that includes structured teaching, assessments, and practical components, covering critical areas in the practice of space medicine; master’s degree (1 to 2 years) covering the fundamental of space medicine with a rigorous research component to improve the safety and health of space-farers; and a residency program (2–4 years) that trains physicians to become certified space medicine specialists. This paper advocates for establishing comprehensive education and training programs in space medicine globally, emphasizing the Middle East due to its burgeoning space ambitions.
INTRODUCTION
Human space exploration has entered an unprecedented phase, driven by increased commercial activities, multinational collaborations, and ambitious projects such as the Artemis program by the National Aeronautics and Space Administration (NASA), China’s Tiangong space station, and numerous private ventures. 1 This “second space age” leverages cutting-edge technologies in molecular biology, precision medicine, and biotechnology, underscoring the urgent need for specialized education in space medicine. 2
Despite its critical role, awareness and structured education in space medicine remain limited, particularly in regions newly engaging in space activities, such as the Middle East. 3 This paper argues for robust global educational initiatives tailored to varying professional demands, highlighting the Middle East as a case for immediate and structured educational interventions.
THE CURRENT STATUS AND IMPORTANCE OF SPACE MEDICINE
Space medicine is defined as the medical specialty dedicated to ensuring human health and performance in the extreme environment of space, addressing challenges such as microgravity, radiation exposure, and neuro-ocular disorders. 4 Historically, advancements in space medicine have significantly contributed to terrestrial health care, exemplified by technologies like insulin pumps and cochlear implants. 5 Space medicine is fundamental to human exploration of space, including future planned crewed long-duration missions to the Moon, Mars, and beyond, as it underpins the health, performance, and survival of crews on historic missions such as the inaugural crewed flight to Mars. 6
Medical conditions in space range from cardiovascular and musculoskeletal disorders to neuro-ocular syndromes and behavioral health issues, necessitating comprehensive training programs to equip health care providers adequately. 7 The reported adverse health conditions during and after spaceflight threaten the health status of the space-farer but also impair performance and success of space missions. These include the effects of exposure to space radiation leading to the (1) risk of cancer, (2) cardiovascular disease, (3) cognitive decline, (4) damage to the central nervous system, and (5) behavioral changes. 8 Also, the effects of exposure to microgravity result in (1) musculoskeletal and skeletal adverse outcomes, including bone density loss (osteopenia), muscle atrophy, lengthening of the spine and back pain, and general loss of body mass; (2) vision and ocular effects, such as Spaceflight Associated Neuro-ocular Syndrome and other vision changes; (3) cardiovascular and circulatory changes that result in slowed cardiovascular system function and decreased red blood cell production; (4) hearing loss; (5) neurovestibular effects, such as motion sickness and balance disorders; (5) weakened immune system and response to infection and disease; (6) behavioral, cognitive, and psychological effects, resulting in cognitive decrements, performance errors, anxiety, depression, difficulties with psychosocial adaptation, sleep disturbances, and circadian rhythm disorders; and (7) digestive and nutritional issues related to constipation, food poisoning, and difficulties with nutrition and digestion.9,10 Each of these categories of reported health effects must be robustly studied for the purpose of identifying effective countermeasures and mitigation strategies. 11
GLOBAL DEMAND AND STRATEGIC RELEVANCE
Globally, space medicine education programs exist predominantly in the United States, Russia, and Europe, focusing on established space agencies like NASA, Roscosmos, and the European Space Agency. However, recent commercial spaceflight expansions by companies such as SpaceX, Blue Origin, and Virgin Galactic underscore the critical need for broader, globally accessible training programs. 12
With increased civilian space travel, understanding and mitigating spaceflight-induced health risks have become paramount. 13 Moreover, as the commercial spaceflight industry seeks to make space inclusive and accessible for all who desire to travel, this goal creates a new challenge: establishing appropriate medical guidelines will require the involvement of health care professionals and scientists from diverse backgrounds, all of whom will need education in space medicine to contribute meaningfully. 14
EMPHASIS ON THE MIDDLE EAST
The Middle East, notably Saudi Arabia and the United Arab Emirates (UAE), has expressed significant space ambitions aligned with their national development visions. 15 Saudi Arabia’s Vision 2030 explicitly emphasizes economic diversification through knowledge-based industries, including space medicine. The establishment of the Saudi Space Commission (now the Saudi Space Agency) in 2018 highlighted the country’s commitment to becoming a leading player in space exploration and medicine. 16
A recent survey demonstrated that while most Saudi health care professionals and students had limited prior knowledge of space medicine, the majority expressed significant interest in pursuing careers in the field if provided opportunities. 17 This gap between interest and awareness indicates a substantial latent demand for structured educational initiatives.
Founded in 2014, the UAE Space Agency sets national space policy and serves as the sector’s principal regulatory authority.18,19 The Mohammed bin Rashid Space Center was established in 2015 and executes satellite projects and manages the UAE astronaut program. 3 Under their collective efforts, space medicine research has accelerated, yielding new insights into the physiological and psychological effects of human spaceflight.
Moreover, the UAE’s 100-year national program aims to develop national cadres capable of achieving scientific breakthroughs and facilitating human transportation to Mars in the next decades. 19 The UAE’s 100-year plan aims to develop space science expertise via scientific research programs at universities. It will instill a desire for space in future generations. The project will result in a variety of research activities, including life support systems for Mars. The UAE Space Exploration Vision aims to create scientific capabilities for a sustainable human colony on Mars. 19 Aligned with this long-term vision, the proposed educational cascade will systematically develop the multidisciplinary expertise needed to advance the UAE and the region’s space ambitions.

By integrating these structured academic and practical components, space medicine education programs will successfully prepare health care professionals to address the unique medical and operational challenges inherent in human space exploration. Such comprehensive training will ultimately support global collaboration, innovation, and excellence in space medicine, particularly within emerging regions such as the Middle East.
ROADMAP AND IMPLEMENTATION STRATEGY
For the Middle East, creating an independent human space research and educational program is recommended. Partnerships with international institutions could enhance the program’s credibility and effectiveness. 16
To align curriculum complexity with the developing infrastructure and faculty capacity, a clear implementation roadmap includes:
Phase I (Year 1): Launch a short course to build awareness and pilot instructional resources.
Phase II (Years 2 to 3): Introduce a postgraduate diploma that consolidates the short course content into a coherent, credit-bearing pathway.
Phase III (Years 4 to 5): Expand to a full master’s program and an accredited residency, benefiting from the faculty, facilities, and partnerships matured in phases I to II.
A structured blueprint for building these space medicine training programs will be followed. Kern’s six-step curriculum-development model for medical education will serve as the guiding framework. 27 By moving systematically from (1) problem identification, general needs assessment and (2) targeted needs assessment, the framework lays the foundation. It then advances to (3) explicit goals and objectives and (4) aligned educational strategies. Finally, steps (5) implementation and (6) evaluation and feedback ensure coherence between learning outcomes and regional educational needs. 28
The curriculum will accommodate both part-time and full-time enrollment, delivered through a blended model that mixes online learning with targeted face-to-face sessions. Instruction combines asynchronous, self-paced materials with scheduled synchronous discussions to encourage real-time interaction and teamwork. Complementing the virtual components is hands-on workshops, laboratory sessions, simulation training, and guided tour visits to partner space centers and institutions. Formal collaboration agreements and industry partnerships will embed students within active research and operational environments, ensuring the program remains practice-oriented and globally connected.
BENEFITS AND GLOBAL IMPLICATIONS
The benefits of establishing structured space medicine education are multifold. Educational programs can significantly improve Earth-based health care through technology transfer, enhance national prestige in space exploration, and build regional expertise capable of leading international collaborations. 29
Remote sensing technologies, telemedicine innovations, and biotechnological advancements originating from space medicine research can be directly applied to Earth-based health care, demonstrating tangible global benefits. 30
CHALLENGES AND FUTURE PROSPECTS
Challenges include funding, limited existing expertise, and a need for sustained governmental support. Overcoming these requires clear national and international collaborations and investments in educational infrastructure and faculty development.
The gap of limited local pool of experienced space medicine educators can be bridged initially by encouraging visiting professor schemes in addition to short secondments from faculty from international space associations. Visiting professors may deliver key modules while mentoring region-based clinicians into future instructor roles. Such adaptation will support national capacity building for the region’s expanding role in space exploration leadership.
The future of space medicine education is promising, given growing global interest in space exploration. 31 Collaborative initiatives could serve as models, providing globally recognized certifications and setting educational standards.
