The six members of Expedition 42 are currently safely onboard the Russian segment of the International Space Station sealed off from the rest of the orbiting laboratory after an increase in pressure in a water cooling line was spotted. It was feared Ammonia had leaked into the water which is fed into the crew modules.
At the time of writing, it is strongly suspected due to lack of data supporting a leak, that is was indeed a false alarm. The crew are currently still in the Russian segment of the Station with hope of opening the hatches later today.
