Deep-Space Telehealth Delay Simulator

Astronaut telemedicine is bottlenecked by two separate, additive delays: how far light has to travel, and how long the link takes to push the actual medical data through at its available bandwidth. This simulator places the Earth and Mars on real, independently-orbiting circular paths driven by a mission-day timeline, computes the true line-of-sight distance and its resulting light-speed propagation delay with a law-of-cosines calculation, and layers a bandwidth-limited transfer-time model on top for a chosen medical payload — an ECG snapshot, a lab panel, a video-consult clip, or a full diagnostic-imaging batch. A recommended communication mode (live video, delayed video, store-and-forward telemetry, or fully autonomous AI diagnosis) updates live from the combined round-trip delay, matching the thresholds real Mars-mission medical planning has to work within.
