that when you are in space. reporter: maybe not. he will have a new space suit ready to wear when they head out tuesday. you are welcome. thank you, good job. reporter: all right, nasa has about 12 of these space suits. they already had a spare space suit on board. that is being refit today. they want it to fit perfectly within they head out tomorrow. have they fixed out what happened in the july incident, yet? these two are not related. they are trying to figure out what happened in july and how could it happen again or could it happen again? they tell us they made modifications to fix the problems tchlts problems are related. nasa said they put pads in the back of the helmet so the astronauts can tip their heads back and see if there is moisture in the helmets. they didn t experience any moisture. nasa equipped them with snorkels in case water approaches again. it seems like an odd fix.
snorkels they can use if water did get into the helmets. snorkels. who would have thought. alexandra, it s an interesting time for the international space station in the post shuttle era. what s next for the iss? well, brianna, right now we know this space walk, an important space walk designed to replace this faulty pump was supposed to include three different space walks. it looks like they ll be able to get it done in two. we know the u.s. sent up a bunch of spare parts. they had to send up spare parts because you can t send them now when needed. the pump was there and will be replaced and the working go on. good to know they were prepared. thanks so much. and there s a change to the health care deadline. we ve been talking a little bit about it today. the government giving a little more time for people to sign up. our mark preston will take a look at why next. to help secure retirements and protect financial futures. to help communities
right. that incident nearly drowned him. this time, though, the nasa astronauts are equipped with the snorkels to allow them to keep breathing if there is a sudden water leak. is that a permanent fix for potential risk? if you ask if they permanently have snorkels, i don t know. we try to put the crew in the safest possible manner. the investigation on the malfunction is ongoing. we don t have a smoking gup yet. one thing that was found by nasa was contaminant in the water separators. that could have led to what happened. so like you said, the first line of defense is absorption pad behind the astronaut head inside the helmet itself. they are good for 600 to 800-milliliters of water. if that doesn t work, obviously, if there is any leak at all. the spacewalk is over. we would stop what they are doing. and head back inside.
fraud. cancel your card or change your account number. if you think our identity might have been stolen, put a freeze on your credit. credit cards are safer. if you have to use the debt card, choose credit instead of debit. avoid using the four-digit pin. so, do you worry about fraud when using your debit and credit cards? you can talk to me on twitter? @alexwitt. a critical mission is under way in space. why astronauts will have snorkels.

the door on saturday. reporter: a valve inside the pump failed over a week ago. complicating matters nasa has to carefully watch the crew s spacesuits. back in july, astronaut lucca s help mitt began mistierly filling with water. scary moments as others raced to get his helmet off. nasa still doesn t completely understand what went wrong. this will be the first walk since. all days spent with a lot of water chemists trying to figure this out. we ve not yet said it will be fleet-wide. reporter: they don t expect the problem to repeat but are taking no chances. water absorbing pads have been installed in helmets and tubing on the station fashioned into snorkels. this is your last resort, if water is encroaching your face, similar to happened to lucca the crew member can lean down and use this to breathe to receive fresh oxygen down near his
