Canadian Space Agency's Joshua Kutryk, NASA's Jessica Watkins and Luke Delaney, and Roscosmos's Andrey Fedyaev run through emergency procedures at NASA's Johnson Space Center.

Astronauts train for all sorts of different situations that they could encounter during their mission. Emergency training simulates dangers like fire, depressurization, and air contamination.   (Credit: NASA/David DeHoyos)
