Perspective Chapter: Beyond the Algorithm – The Irreplaceable Role of Human Doctors in Space

摘要

As human spaceflight moves from the relative safety of low Earth orbit to the Moon, Mars, and beyond, the demands on medical care will change in unprecedented ways. This chapter examines the evolving role of the “space surgeon,” a dedicated, highly trained physician prepared to address the full spectrum of medical care in an environment where evacuation is improbable, resources are constrained, and communication delays hinder real-time guidance from Earth. Drawing on lessons from six decades of human spaceflight, the unique physiological, operational, and psychological challenges of long-duration missions are discussed, including microgravity-induced physiological impairments, radiation exposure, and the stresses of isolation and confinement. This chapter evaluates how emerging technologies like autonomous diagnostics, robotics, and artificial intelligence, can extend medical capabilities in space, while underscoring their limits in replacing human judgment, adaptability, and compassion. Through an integrated discussion of risks, operational constraints, and mission-critical contingencies, an argument is made that despite rapid advances in medical technology, the presence of a skilled human physician will remain indispensable for safeguarding crew health, ensuring mission resilience, and enabling the next era of deep space exploration.
