NASA has not yet determined what went wrong when Astronaut Luca Parmitano’s spacesuit filled with water from a leaking assemblage on his July 16 spacewalk. If you want to do some of your own speculating about the cause of one of the worst EVA incidents in spaceflight history, you can start with a study of the makeup of the Extravehicular Mobility Unit (EMU) that Parmitano was wearing at the time.
Need even more background? Check out our series on the history of pressure suits. The third installment will be coming up in the Summer 2013 issue of Space Safety Magazine.
