NASA halts spacewalks after finding leak in spacesuit

NASA has halted spacewalks while it investigates an incident where water leaked into an astronaut's helmet. The investigation has sparked concerns over the reliability of the spacesuits being used by astronauts, some of which are decades old. The incident is similar to one suffered by ESA astronaut Luca Parmitano where coolant leaked from within his suit and dripped on his head – nearly causing him to drown.
