 Roger, I'd like to confirm whether or not you have gotten to stepcharly.22. 20, but I've closed out the vent valve. Copy. And also, Roger, while you're waiting, if possible, we'd like you to square up the TBC-1. It got bumped. Based up, just want to verify that there's argon and helium regulators. They're still in a good position before I move on to do the GC calibration. Affirmative. They still look good. May I sell a pencil for Greg? Affirmative. This is the first test point of the group, and you will select calibrate as well. Stand by one, please. Got to do something here in the tunnel. Okay, I'm ready to go here. I'm going to just repeat what I'm going to do. Be sure we've got this clear. When I keep the flame within the field of view of the image, I'm going to prevent it from lifting off. If it does lift off, I'll reattach it. I'll go slowly and try and find the smoke point. We've got six clicks in either direction. That's a good recap. Here we go, filling the fuel line. I think that'll occur in the middle of the video tape of Susan's IFM. Why don't we go ahead and start, and you'll tell us to hold off, to pause here at the appropriate time. Okay. I'm working on the droplet combustion experiment, and one of the things we have to do on this experiment is introduce the proper atmosphere into the test chamber. I've unstowed a new bottle, and I'm installing it into the test chamber here. This we do several times per day, perhaps. Then we get many burns, many droplet burns out of each atmosphere, so that we can test the burning over a range of conditions. Here I'm working on a glove box experiment. This one's called CHT, which is capillary-driven heat transfer. This is an experiment that comes out of the University of Dayton in my home state of Ohio. Here I'm taking out a test cell with a heat pipe, actually a capillary-pumped loop. What this is is a closed-loop system for transferring heat. We heat a fluid at one end of this loop, and it turns the vapor, transfers to a cold end, and condenses. It's a great way to transfer heat in space. This is the kind of technology we need if we're going to go to Mars, because it's wonderful. It has no moving parts to it, and it's got a long life. Here I'm shifting some of the fluid around. We don't have gravity to help get bubbles out, so when a bubble does form, we just put a little centrifugal force on it and move the bubble that way. Here I'm reinstalling it in the glove box, and these heat pipes have great application on the ground, potential for the future for getting some of the geothermal heat from the ground and transferring up to the sidewalks to melt snow, for example, in the wintertime, or having them on bridges so that we never have to worry about ice in the wintertime also. This is a procedure called an in-flight maintenance procedure. This is something that you don't expect to have to do, but if you do, the ground will send up a procedure. In this particular case, I am removing one of the lockers from the mid-deck. I'm going to go back behind the wall and inspect out so we can have the right configuration on entry. Sometimes we have to work in some tight places. Here you can see two bolts side by side. One from the locker I just removed and one from the locus and point to the ones. Dig loose in the bolt a couple of turns. Focus in on the front part of the bolt so you can get a better look at that. There's the front end of the bolt. It is very secure. And I think all of us here are confident that that bolt will work just fine for entry and hold the locker in place or ASRA PGBA if that's where we decide to place that experiment. Two-choice downlink. Once again we'd like to say thanks to Mission Control. We know I said it was halfway through for the flight crew. It's also halfway through for Mission Control and haven't been a capcom. I understand how hard y'all have to work for long, unending hours to make them look this easy to us. So we certainly appreciate your work. We will do it again tomorrow. Thanks a lot. And Janice, if you would try to give them a call. Thank you, Janice. I'm glad to hear you've got some. It's got even got Russian art. They translate it into 100 milliliters so we had to do some conversion here to get it to work on the gap. We're going to see all that stuff. It looks a lot like what you think it would from the thoughts that have been with you. As you've dealt with the bombs that you had to dealt, you've done just an outstanding job. So we would appreciate it if you would pass on to your chromatic nips that we think they're doing up there. Pleasure. And we sure appreciate you folks letting us listen along with you.
