Astronauts are expected to train extensively for space missions. Crew member medical training is an important component of astronaut training that could potentially have significant implications on astronaut health and safety. Specifically, long duration space missions put crew members at higher risks. Although ultrasound is a critical diagnostic modality in this environment, extensive premission ultrasound training is currently not done [1]. Introductory lessons on technique, equipment, and remote guidance are given months in advance of the mission. During spaceflight, ground-based subject matter experts remotely guide the astronaut through imaging in a step-by-step manner.

Crew members receive a 1 hr didactic and approximately 2 hrs “hands-on” practice session prior to their flight [2]. Crew members are required to be trained in ultrasonography in order to assist flight surgeons in diagnosing injuries or monitoring physiological changes during missions due to microgravity environments.
