HERCULES

Proven Leader in Aerospace Medical Support For Earth and Beyond


Hercules Medical Group is a specialized aerospace medical organization committed to protecting the health, safety, and mission readiness of those who venture beyond Earth. We deliver comprehensive medical support from pre-flight evaluations to post-flight recovery.

Our team of aerospace medicine boarded physicians and other specialists bring deep expertise and precision to every mission and uphold the highest standards of medical care in the most demanding environments. 

Hercules Medical Group has more experience supporting orbital commercial human spaceflight than any other company, being the medical services provider for all four private astronaut missions to the International Space Station flown to date.

While our foundation is firmly rooted in supporting human spaceflight, we are expanding our vision to support other organizations looking for unique medical solutions in the aerospace and aviation sector. Hercules is committed to ensuring those who take flight are prepared, protected, and mission ready.

Comprehensive Medical Support: Your Mission’s Best Investment

  • Our approach to comprehensive medical support in human spaceflight helps identify and manage health risks early, preventing last-minute medical issues that could delay launch or force mission cancellation. By ensuring crew members are flight-ready and equipped to handle in-flight health concerns, medical oversight minimizes costly launch delays, emergency interventions, and aborted missions. Proactive medical evaluation and planning protect both the mission timeline and the significant financial investments tied to each flight.

  • Spaceflight involves unique risks, including extreme environments (radiation, pressure, temperature), physical stress from microgravity and launch forces, and psychological challenges in a unique operating environment. Crews must also operate complex systems where safety and precision are critical.

  • As commercial spaceflight evolves from novelty to enterprise, crew safety must advance in parallel. Operating without dedicated medical oversight introduces critical risks to crew health and performance, as well as mission success.

  • We take a proactive approach to comprehensive prevention of health issues prior launch, personalizing care for each crew member, and ensuring all medical standards for safe human spaceflight are met.

  • We provide continuous medical support throughout pre-flight quarantine and launch operations as well as in-flight support performing in-flight private medical conferences for each crew members, responding quickly to any in-flight health issues, and helping to maintain crew psychological well-being throughout the mission.

  • We provide support throughout landing operations to monitor crew health in real time and manage any immediate medical issues. After landing, we help guide the safe recovery and rehabilitation process, addressing challenges like orthostatic intolerance, muscle weakness, and balance disturbances as the crew readapts to Earth’s gravity. Continuous post-mission care also provides critical data to improve health protocols for future spaceflights.

Corporate Practice of Medicine Solutions

The Corporate Practice of Medicine (CPOM) legal doctrine in most states prohibits corporations from directly employing or controlling physicians to ensure that medical decisions remain independent and patient-focused. In many states, this means corporations cannot dictate how doctors practice medicine, preserving the physician’s professional judgment and preventing conflicts of interest. As a result, companies must structure relationships to physicians and other medical providers carefully to comply with these restrictions and avoid legal penalties.

Hercules Medical Group can assist companies with specialized medical support needs develop unique solutions that comply with the CPOM restrictions specific to their state, whether within the aerospace sector or others.
