tubes in it. the water circulates around your body to keep your heat down. if you don t have the cooling system, you re going to overheat. it s game over. you have to come inside. the water came from the mix of the air and water. a complicated system, but it does miracles that holds the spacesuits we have. that was where the water came from. from the cooling water mixed with the air incorrectly and ended up coming in to the suit. john, i want to go back to you quickly. you touched on earlier how serious the shutdown of this coolant pump is, but what happens if the astronauts can t fix it? i mean, that s certainly a possibility. well, you know, bottom line is, you have it s a backup. a spare, and they re pretty confident the spare s going to work once they get it in there, but they can limp along with the one that they have working right now. and, of course, if god forbid they were to lose two of them, then they would have to rely on the russian remember the russian side of the
midsection. reporter: nasa astronauts always make space walks look easy, but the bottom line, navy s agency never wants to send them outside unless there is no other choice. this happens to be one of those times. victor, pam? all right, john zarrella in miami. thank you so much, john. hundreds of thousands of people are demanding that a & e end the suspension of one of the stars of duck dynasty. really a talker. find out what he s saying about the suspension now. [ male announcer ] this is george.
this astronaut and the sorry in the all white suit. obviously, this mission is inherently risky. mike, i want to go to you now. you know firsthand that the risks that these astronauts face. remember six months ago when that italian astronaut almost drown because of the water that got into this helmet. what is nasa doing, mike, to minimize the risk for these astronauts? well first, pamela and victor, thanks for having me on. john, it s good to hear your voice. they ve done a couple things. the problem that lucca, the italian astronaut, the problem he had, they re still looking into the actual cause of that, but they know whatever happened to cause the problem is a pump fan assembly that circulates air and water through the spacesuit. that got mixed, and floated, was forced into lucca s helmet area. that s what caused the problem. they removed that pump assembly.
let s bring our guests in now. rick, and mike are the astronauts. we ve got john zarrella, with us, also mike massimino, who joins us to talk us through what s happening. i want to start with you, john. tell us what s happening now. we re just a few minutes in to this. yeah, that s it. right now the astronauts have just exited the air lock there and they are going through some preps and check outs. mike massimino knows all about this from the space walks that he s done, and ultimately what s going to happen is on the end of the robotic arm, one of the astronauts, for much of this day. this first day out there while they re working, what they re going to be doing is preparing to change out that whole cooling pump box and put the new one in, but today is just disconnecting wiring and hoses and pumps and electrical connectors so that they can, then, get to that box,
minutes or so positirep before do the space walk. unbelievable video courtesy nasa tv. john zarrella and mike massimino, thank you both. thank you. target says, sorry. with a 10% discount, and, of course, that s not it. not at all. it s also offering customers, after millions of shoppers got credit and debit cards hacked, offering customers a credit monitoring. details on that, next. side-by-side, so you get the same coverage,
