a father and daughter on a fishing trip in new jersey made a surprise discovery this week. instead of catching fish, they reeled in a wallet full of mud. it contained credit cards and a car key. they managed to track down the owner. he lost the wallet while jet skiing back in 1989. wow. well, two astronauts are in the beginning stages of a seven-hour space walk this morning. those astronauts are repairing a component on the international space station that provides cooling to the electronic equipment. let s get right to nbc s jay bar bring who barbary. this is no routine mission. this has danger involved here. reporter: it sure has. it s probably the most dangerous yet, alex, that they ve undertaken up there. this is space walk number 148 since they started building the space station, hooking it
together. the first one was in december 1998. so this one makes it so dangerous is because they re having to disconnect the ammonia lines under pressure. ammonia is toxic. if they get it on their suits, they have to stay out there until it evaporates because they can t bring it back inside the space station where you have four more members of the crew. they don t want to be breathing this. so they have to watch what they re doing. but so far everything is going perfectly. they re about a third of the way through the space walk. they have this failed ammonia pump unhooked. they re putting it on what they call the little cart which will run it down the backbone of this space station like a push cart or a railway, if you will. and, you know, this thing is longer than a football field. yeah. it s 330 feet long or so. so jay, this is already a long space walk. so if the unthinkable happens
