Astronauts Explain Emergency Spacesuit Helmet Leak During ISS Work

Zero-gravity conditions can present disorienting, sometimes dangerous, challenges for astronauts conducting a spacewalk. In 2013, ESA astronaut Luca Parmitano and NASA astronaut Chris Cassidy were hard at work outside the International Space Station (ISS), when water started to leak into Luca Parmitano's space suit helmet, immediately resulting in the duo heading back to the Quest Airlock to terminate the EVA. Now, in collaboration with NASA, researchers from the Cambridge, MA-based nonprofit Draper are developing a new kind of spacesuit with a backup capability that secures a safe trip back to the space station.
