Is it merely a contusion, or could it indicate a more serious medical issue? This scenario underscores the critical need for robust space healthcare systems for lunar missions and beyond, a challenge addressed by NASA and organizations like TRISH, focusing on astronaut health during deep space exploration and remote environments.
Comprehensive Medical Support for Lunar Missions
Determining the severity of such an incident necessitates immediate assessment and medical attention from the mission’s medical officer, situated at the lunar habitat. This officer may then need to consult with flight surgeons at mission control on Earth. Providing optimal care requires the medical officer to have instant access to the astronaut’s complete medical history, alongside a range of diagnostic instruments and physiological monitoring equipment to accurately evaluate the situation and guide appropriate treatment.
Addressing Healthcare Gaps in Space Exploration
Current medical protocols in low Earth orbit (LEO) on the International Space Station (ISS) rely heavily on real-time guidance from Earth-based medical experts. However, as we venture further, utilizing the lunar environment as a stepping stone for extended missions beyond Earth, self-sufficiency becomes paramount. This shift demands a fundamental rethinking of remote healthcare delivery in deep space environments.
TRISH and NASA: Pioneering Deep Space Medical Solutions
The development of advanced medical tools and innovative healthcare strategies for space exploration is a key priority for the Translational Research Institute of Space Health (TRISH), supported by NASA. Preparing for potential trauma and medical emergencies during demanding exploration missions to the Moon and Mars is crucial for astronaut safety and mission success.
Artemis Missions and the Imperative of Seamless Healthcare
NASA’s Artemis program, with Artemis 2’s lunar flyby paving the way for Artemis 3’s lunar landing, highlights the complexities of space travel. Astronauts will operate across diverse environments: the transit spacecraft, the lunar-orbiting Gateway station, lunar habitats, and exploration rovers. Given NASA’s plans to involve private companies in developing these elements, it’s highly probable that various entities will own and manage these habitats and vehicles. Therefore, medical preparedness must be comprehensive and interoperable across all vehicles and systems, ensuring uninterrupted access to necessary medical care for astronauts, regardless of their location.

Mitigating Health Risks in Deep Space
Astronauts also face health risks associated with prolonged space exposure, including radiation from solar particle events. In a lunar medical emergency, rapid Earth return is neither feasible nor safe, especially if an astronaut’s condition is critical. Consequently, crews must be equipped for on-site treatment and continuous health monitoring. Vigilant tracking of physiological changes and proactive identification of potential health issues before they escalate are essential aspects of deep space medical care.
HERMES: An Integrated Healthcare System for Astronauts
In 2024, a research initiative was launched to address these challenges, aiming to create HERMES (Health and Emergency Readiness for Medical Extended Spaceflight), a medical architecture designed for continuous astronaut health surveillance. HERMES seeks to detect early indicators of potential illness or physiological changes and provide guidance for effective medical interventions. While HERMES has been demonstrated, in-space flight and analogue environment testing, such as in Antarctica, are necessary for validation.
Real-Time Data and AI-Driven Medical Decisions
Deep-space missions necessitate immediate access to astronauts’ in-flight medical data and comprehensive medical histories. Currently, this information is primarily located at mission control on Earth; however, future missions will require localized support within spacecraft for dynamic, immediate decision-making. The system must integrate seamlessly with diverse health monitoring technologies and be adaptable across various spaceflight vehicles, potentially from different providers. Furthermore, continuous updates of crew health information throughout missions are crucial. Integrating artificial intelligence into such a healthcare system offers the potential not only for real-time treatment guidance but also for proactively identifying early signs of illness or declining performance, thereby enhancing astronaut well-being and mission success.
Economic and Safety Benefits of Space Healthcare Investment
Investment in astronaut health and performance capabilities by companies constructing space habitats, vehicles, and platforms is vital not only for protecting space explorers, military personnel, and space industry workers but also for ensuring the long-term viability of the space industry itself. A serious, unaddressed medical incident could erode public trust and negatively impact the perceived risk-benefit balance of crewed space missions.
A Lunar Medical Scenario: The Importance of HERMES-like Systems
A positive outcome during a health event hinges on numerous critical decision points requiring informed choices. To illustrate the significance of a real-time, informed healthcare system during Artemis-like missions, consider again the hypothetical lunar fall incident and how a comprehensive healthcare platform, similar to HERMES, could manage such a medical emergency far from Earth.
Immediate Response and Initial Assessment on the Moon
Following the fall, your geological tasks are paused as you prepare to return to the lunar habitat. Your crewmate assists you into a pressurized lunar rover. Mirroring terrestrial medical appointments, the initial step involves recording vital signs within a HERMES-type platform. Removing your spacesuit and donning a wearable sensor allows for continuous measurement of ECG, heart rate, and other key metrics. As the rover traverses the uneven lunar terrain, you experience fluctuating, sharp pain. Capturing these pain variations is essential for accurate diagnosis, emphasizing the importance of continuous and comprehensive vital readings.
Habitat Examination and Data Charting
Upon reaching the habitat and passing through the airlock, a medical examination ensues. The chief medical officer (CMO) notes a minor laceration from the pickaxe and documents it with a photograph. They record your pain description and observe an elevated heart rate. This crucial data is locally stored for future reference and transmitted to mission control for consultation. Similar to standard Earth-based medical practice, real-time charting during lunar medical assessments ensures accuracy, improves decision-making, enhances emergency response efficiency, and provides transparency for all parties involved. In remote settings like the Moon, real-time charting becomes even more critical, especially with potential medical care delivered across shifts and the need for up-to-date information for Earth-based support teams assisting from afar.
Diagnostic Insights and Treatment Guidance
Analyzing the collected data, the lunar CMO identifies a significant detail in your medical history: a previous non-obstructing kidney stone. Considering this and the nature of your reported pain, a thorough investigation is warranted. Utilizing a handheld ultrasound device, guided by real-time training videos and imagery (envisaged within HERMES), the CMO, in consultation with mission control, confirms a partially obstructing kidney stone near the uretero-pelvic junction. Pain management is initiated with onboard medications, and continuous monitoring is implemented. As full mission capacity is compromised, transport to the Gateway station for burst wave lithotripsy becomes necessary. This procedure, utilizing image-guided ultrasound and HERMES-enabled AI assistance, helps identify optimal settings to dissolve the stone. Post-treatment ultrasound images are transmitted to Earth when bandwidth permits. After three days of observation, mission resumption is authorized.
Post-Mission Care and Data Continuity
Upon returning to Earth, post-mission medical care benefits from seamless data capture and transmission. Your Earth-based physician gains access to your complete spaceflight medical records. This coordinated, comprehensive care model embodies HERMES’s objective of ensuring astronaut well-being during and after space missions.
