Last Monday morning, NASA astronauts were forced to postpone a spacewalk at the International Space Station due to a water leak from one of the spacesuits, NASA Postponed ISS Spacewalk Over Spacesuit Water Leak: Are Astronauts Safe? Fortunately, the astronauts were not in danger, and the leak was detected before they floated outside. The planned spacewalk, which aimed to address a faulty communications box and collect microbe samples, lasted only half an hour.
