The Martian chronicles

Abstract

Despite rigorous health screening in astronaut crews, there are a number of conditions that may occur during long duration, exploration class spaceflight. The risk of abdominal conditions requiring surgical intervention is not clear, yet submarine and polar base experiences suggest contingency planning is warranted. While radio communication time delay is only 2 s to the international space station (ISS), a potential Mars mission would necessitate time delays of about 15 min. We sought to demonstrate the feasibility of remote expert guidance of diagnostic ultrasound followed by laparoscopic appendectomy in a simulated Mars environment.
