Abstract
Earth-Moon telemedicine consultations are complicated by a 2.6-second round-trip communication delay, making real-time dialogue cumbersome and procedure guidance impractical. This review evaluates structured consultation frameworks, asynchronous consultation models, and AI-assisted decision support designed for the lunar communication environment.
The 2.6-second round-trip delay between Earth and Moon (1.3 seconds each way at mean orbital distance) transforms telemedicine from a video call into something closer to a structured dialogue protocol. Natural conversation is difficult: both parties instinctively begin speaking during the pause, creating crosstalk.
Protocol optimization has focused on three approaches: (1) Structured turn-taking with explicit end-of-transmission markers, adopted from radio communication protocols; (2) Pre-consultation data packages — the lunar medical officer uploads all relevant data (history, vitals, imaging, video) before the call, enabling the Earth specialist to arrive prepared; (3) Asynchronous store-and-forward consultation for non-urgent cases, eliminating the delay problem entirely.
For procedure guidance (endotracheal intubation, chest tube placement, emergency surgical procedures), the delay makes real-time instruction impractical. Our solution: pre-recorded procedure guidance libraries tailored to the lunar medical bay's specific equipment, supplemented by AI-assisted decision support with no communication latency.
At 1.3 seconds out and 1.3 seconds back, the lunar medical officer is ultimately on their own. The role of Earth telemedicine is preparation, not real-time rescue.
