A sudden increase in a previously small ammonia leak in the coolant lines of a power channel on the outside of the International Space Station (ISS) has prompted ground teams to enter into a state of rapid investigations and replanning, in order to stop the ammonia from leaking away into space as soon as is possible. Previously unplanned spacewalks are imminent – the first to take place on Saturday – in order to rectify the leak.
