chris cassidy and tom marshburn are in the air lock and they'll be headed out to fix an ammonia leak in just a moment. we want to bring in cnn's john zarrella covering this from miami. walk us through leading up to this moment, what's going to happen as they start this emergency space walk as they call it. >> reporter: sure, they're a little bit behind schedule, had a little more difficulty getting suited up and getting into the outer portion where they are now but as you mentioned they should be out momentarily. what happened was about 48 hours ago the crew began to notice flakes, white flakes coming out of a section of the international space station. so they fairly quickly identified that it was ammonia leaking out, and ammonia is used to cool the space station. space station generates a lot of heat. ammonia absorbs the heat and it's pumped out of the space station. now give the viewers a look at what we're talking about here. the astronauts will traverse out here along this truss, the backbone of the station and in this area, right around where all of these solar arrays are, ther

now right there you're looking at that i believe yes, chris cassidy's helmet cam, on the bottom right you may be able to make out the number 20. that's an indication that it's chris cassidy's camera we're looking at, as he's doing some prep work and the helmet cam 18, if you see that one, that's tom marshburn's camera and he literally had a camera in his hand a few minutes ago, they're going to take images to send down to mission control so they can get an idea of what may or may not be happening but cassidy already reported at one point that he doesn't see anything, they don't see any flakes out there, brianna, those white flakes again, so this may be a little more difficult than they had anticipated finding this leak. >> john zarrella, thank you so much for that as we keep an eye on this emergency space walk and thank you to all of you for watching this morning. i'll see you back here in 30 minutes. first christine romans welcomes christiane amanpour for a special edition of "your money" that starts right now. >> you're out for a bargain but getting the best price may come at too hi

under where the astronauts have done that space walk how they finished and what's the up well chris cassidy and thomas marshburn two astronauts which you can roughly make out on this live on these live pictures from us they haven't actually found a leak. have replaced those pumps what was white these weight white flakes that was really found on thursday seen by the commander of the space station chris hadfield they these two have been sent out today to try and isolate it define exactly where it was and have not come across any more ammonia coming out does that mean the problem is fixed or well exactly does that mean there's a problem even now well it obviously was a problem somewhere but they think maybe by replacing these pumps they've eliminated the problem maybe when they put him only a back into the system they'll see that cooling system leaking again and they'll have to go and what's the point of the ammonia that kind of outflow could cool in the fridge as it's happening is an electrical coolant for the powering system that comes in from the solar panels that power the i assess there's

going to be a six hour walk obviously is this enough well it's just the beginning at the moment chris cassidy and thomas marshburn the two astronauts this is rather jumpy sometimes a bit grainy but some live pictures here from a nasa feed of those two astronauts up on the side of the international space station they have indeed found just very small traces unfortunately that's nothing special very small traces of that ammonia that was leaking out earlier they're looking for something more substantial and in the process of that operation they're going to try and find the cause of what we've seen lots of crystals leaving earlier described by the station's commander chris hadfield. a very steady stream of. profits got out of comics earlier and i rotated in towards florida so you know as we are we trust rotating surface waiting ritualistic they're always getting it if you're out of the. so there are two of them so there's two of them working there on the side of the station they've got to the place where where it is they're trying to take off for a pump supply box it's obviously a very complex ov

so right now tom marshburn and chris cassidy, the two u.s. astronauts, are in the quest air lock. they're doing the prebreathing, cleansing their bodies of nitrogen so they can get out there, and in just about an hour from now, they should be egressing the hatch there and beginning what is expected to be, victor, a 6 1/2 hour space walk to try to isolate, find the problem, and hopefully to fix it. victor? >> john zarrella for us in miami. following the commander chris hatchell on line.

a bit of a funny signal at times but chris cassidy and thomas marshburn have been up there just over two hours now on the outside of the international space station working steadily and i thought it clear through trying to find this leak they still haven't managed to get to the bottom of where this leads coming from what part of the machinery went wrong they've in the process of changing a pump system which they thought may have been had something to do with it they think it's probably just a precaution changing it at the moment earlier on the commander of the international space station chris hadfield how did conversation with nasa mission control about what exactly was happening we have a. very steady stream of. got out of the material by rotating towards the forward you know as the trust rotating we're just waiting for to rotate there are we getting it if you want to jump so as that space walk continues everyone's eyes now as the time continues looking at what could be behind this locator well two hours i said they've been already trying to fix it inch by inch trying to find the r

appears to be thick stuff the two nasa astronauts installed a new cooling pump in the system crewman chris cassidy and thomas marshburn took nearly six hour long space walk to try to tell what caused the leak which was first spotted on thursday and what they didn't find the exact source of the escape replacing a new pump at the suspected problem spot seems they say taking care of a problem says crews still monitoring the situation looking into what may have caused the incident. coming up as well action against the bailout this is still ahead in the program slovenia's package of measures to avert a financial meltdown amid fears it's about to follow cyprus to talk about that in fact in just a few moments. we speak your language. or music programs and documentaries in spanish matters to you. a little too much of angles stories. here. the spanish find out more visit. hello again slovenia is rushing to reform its economy amid mounting concern is next in line for an e.u. bailout plan includes the sale of fifteen state companies tax hikes and public sector wage cuts it comes ahead of a european commissio

what you're looking at there is through the helmet cam of astronaut chris cassidy. what they're doing is removing the spare pump that they have up there. they've already removed the one that was in place, where they thought that they were going to find the leak, or might find the leak. they did not find it. they're saying this ask a vexing problem now. they're not having any joy, they're not seeing the same flakes they saw a couple of days ago. but they decided to go ahead and put the spare pump in, and then they'll move forward with more troubleshooting. it may end up at the end of the day, when they're finished with this 6 1/2-hour space walk, that it's just going to require another space walk by another team down the road, before they actually can isolate the problem. real quickly, brianna, what they were trying to do is get out there as quickly as they could, while that ammonia, the flakes of ammonia were still coming out of that suspect area. but they don't see them now. that may mean there's no more ammonia in the system there. that's why they're not seeing th

crew members chris cassidy and tom mashburn are trying to find the source of a leak that happened yesterdaye crew reported seeing white flakes outside one of the solar arrays. it is leaking ammonia coolant. that cooling system has a long history of small leaks but that the station is capable of operating normally and the crew is not in danger. >>> closer to home now, new details about that multimillion dollar catamaran that capsized in the san francisco bay near treasure island. this morning an australian newspaper is reporting that the boat's new design could be blamed. one of the sailors said the boat cracked and crumbled, trapping and killing andrew simpson. the boats have been redesigned for speed for the summer's america's cup competition in the san francisco bay. and this could be part of the problem.

they get under way this morning, two veteran nasa space walkers chris cassidy and tom marshburn to try to replace the pump essentially. if all goes well the cooling systems come back up and everything will be hunky dory and nobody has a problem. but if they can't fix that, then they start to worry about, well, what is it going to take to address this ammonia leak and what is it going to take to deal with the coolant systems? as you alluded to already, lester, it is very unusual to put together a spacewalk so quickly but they're going to lose the expertise of tom marshburn in a couple days because he is scheduled to return to earth on monday on the soyuz which returns to earth. they want to take advantage of hicks expertise and his colleague's to get them out to fix this as quickly as they can. those two haven't done a space walk in four years so they're relying on some of this, the muscle memory if you will for these two. >> we'll wish them luck with the ultimate do-it-yourself project. thanks very much. >>> there are new questions this morning about the deadly attack in benghazi, liby

>> actually, we're watching remarkable video from the helmet cam of astronaut chris cassidy.side the international space station. they're basically performing some plumbing work 250 miles above the surface of the work. the two astronauts are trying to hunt down and locate the source of an ammonia leak and repair it if they possibly can. we're about one hour into what could be a six-hour spacewalk today, an emergency spacewalk and quick turn around for the two astronauts. >> steve, how did they know something was wrong? >> the crew on board, the six-person crew saw white flakes floating away from the station. looked like snowflakes. it was frozen bits of ammonia floating away. they've had problems in the area before with ammonia leaks. they thought it was the same thing. that's what it was. the attempt to repair and tha and remarkable attitude by the astronauts. the commander tweeted this is what we trained for r, for years. it's a fun day. >> just a little astronaut fun. that's interesting to see the white flakes, right? it does look like snow. but that doesn't make sense. >>
