Today’s spacewalk at ISS to repair a failed voltage regulator of the station’s power system has been cut short because a water bubble had appeared inside one of the astronaut’s spacesuit.
The astronauts are presently in the airlock about to remove their spacesuits, so it appears they are not in danger. However, this problem is the return of the earlier water leaks inside NASA’s spacesuits, something that the agency had thought it had solved last year. If it has returned, this is of serious concern, since it suggests that they have not yet pinpointed the chronic cause of the problem.
It should be noted that the astronauts had successfully replaced the voltage regulator prior to the premature conclusion of their spacewalk. They had had other less critical tasks on their schedule which they had to forego because of the leak.
