Transcript for Astronaut Conducts Spacesuit Analysis
I -- NASA astronaut Chris Cassidy on -- the International Space Station and now last week myself and the department's -- did a spacewalk in which we had. A problem -- -- inside his suit if there was leaking cooling water somehow. He and his. Ventilation system and that water. Cuts into his and to his helmet don't know the exact specifics right now -- engineers and other people in Houston are working on the problem. And try to figured out of this promotion. Soon but I wanted to show you where the water was coming from. Services this is -- his helmet. And the the ventilation air comes into the -- through this port right here. And then goes. Behind. The crew members head. And then blows there oppressive -- interface. Well with water mixture of water and air getting into this vent port. The water bubble started to build up behind is behind this white plastic. Peace. Once the water got big enough that. It went. All the way around and started coming outside. The edge of the way classic that it it -- his his communication have been. Sort of -- closures brought the water -- that all around his head. And he had. Water. Money's been filled up -- is -- coats it is certain to creep into his eyes covered covered his notes scary situation. The ground teams worked really well -- give us direction and as team we've got everybody back and everything was fine. But it the water. Will continue had been -- continually much more it would -- -- -- Soon. That was -- -- -- there's FaceBook. It planned for six and a half hours and it was about it and power -- so. So. Don't know -- rescheduled but the -- The most important thing is that the suits. Are determined to be safe so that whenever the next folks get outside. That it works -- for them. They're actually several ways that water could get inside of -- crew members who. And and and while we're outside we weren't really sure which of those. Methods it was there as fast streak -- it fits -- into this pouch and that's right. In the front. Along your belly. -- -- a little drink to coming out by action. That holds about 32 ounces of water and that was the first place that was suspect we'll be. You there's also sweat but it was a significant amount. More water than what normally would be produced by sweat. It could've been here and although to get their backers that it is very unlikely. And then the other source of water that's out there with us on a -- Is in the cooling -- and we where. Cooling garment. This. Special long underwear like. The -- kind of risk. Tubes woven in cooling tubes. Woven into the fabric. And ventilation lines. -- -- -- -- -- There's plugs into the suit. With a connector here that goes by your belly but. So this was another area that. That. I thought evidently we've. Right and one of this -- here maybe that was -- And then. The -- guts of the -- -- behind in the backpack here and others. Plumbing that goes that where the pursuit and that the ventilation and cooling. Systems. Meet and there's different air bases there that that's what engineers are looking at right now and the ventilation comes into this -- here which makes up with the part of the helmet that are issue. And that's where the water was coming from.
