Update Today on Water-Filled Spacesuit Helmet

NASA Spacewalk Mishap Investigation Board Report

"While I am concerned about ensuring this particular incident does not happen again, I am especially concerned about cultural factors that may have contributed to the event. In our exuberance to get the job done, we may have allowed ourselves to accept the commonly accepted causes for small anomalies. We have a responsibility not to move on from any abnormal situation until we understand it fully or have suitable mitigations to prevent it happening again. Our work both in-house and with our industry and commercial partners should entail diligence in assessing risk and commitment to ensuring mission safety."

"In summary, the causes for this mishap evolved from (1) inorganic materials causing blockage of the drum holes in the EMU water separator resulting in water spilling into the vent loop; (2) the NASA team's lack of knowledge regarding this particular failure mode; and (3) misdiagnosis of this suit failure when it initially occurred on EVA 22."

NASA Updates Media on Spacewalk Safety Investigation

"NASA will host a teleconference at 2 p.m. EST today to discuss the findings of an investigation into the July 2013 spacewalk at the International Space Station when water built up in an astronaut's spacesuit helmet. Soon after the incident, NASA created a Mishap Investigation Board to identify factors that may have contributed to the incident and recommend changes that could be implemented to prevent a similar situation from occurring again. This safety investigation ran concurrently with an engineering investigation into the equipment failure."
