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. ....
But, you know, there s ways to get around it. we don t want to get into that situation, so they re trying to bring up that first loop again so that you have that redundancy. and i read that in order to do this really, you re going to require a space walk. do you agree? maybe. we don t know yet. it s not the whole pump that s failed. they had this problem three years ago where the whole pump was down and they had to replace the pump. in this case, it s a valve inside of the pump assembly. they re trying different things to see if they can command the valve correctly and get it working. if they can t, the worst case scenario is a space walk to replace the whole unit. i don t think they re quite there yet. i know they re working hard and around the clock and working over the weekend to come up with a plan. that s kind of the last the last resort is to do the space walk in this case. sure. it would be, mike, a pleasure to talk to you. thank you very much. thanks for having me. ....
