The agency also revealed that the same suit had leaked only days before, and that this was incorrectly attributed to a minor problem with the drinking water. “The severity of this event wasn’t understood as quickly as it could have been,” says Chris Hansen, chair of the NASA investigation. What caused the clog itself is still unknown. Non-critical spacewalks are on hold until the investigation is complete.
