Last week, an Italian astronaut almost drowned in his flooded helmet while performing a spacewalk.
NASA is still uncertain why water leaked into the helmet worn by Luca Parmitano last Tuesday. But if spare parts are on board, then these repair tools will be useful in swapping out the bad pieces.

Parmitano, meanwhile, is doing fine.
