 The other is the Orbital Acceleration Research Experiment, or OER. Both experiments make use of instruments called accelerometers. I will show you what I mean for an accelerometer. With the weight in the middle is a simple example of an accelerometer. Watch what happens when I move my hand up in a second. For just a moment, the weight in the middle resists the movement. Our eyes serve as the detectors in this demonstration. We see the weight resists the movement, but there is an acceleration. Let's expect an acceleration to make the magnitude of this acceleration with this simple detector. Two tanks, six and seven, heaters, alpha and bravo. All four of those H2 switches to auto. Affirm. Now we'll get the O2, and that's tanks six and seven, heaters, alpha only, two to auto. Only to auto, on six and seven. Affirmative. We're a minute to the ZOE. We'll be AOS at 16-16. It's on the ground. And all of the experiments that we have performed are experiments where the flames are produced, or in fact the flame is rather rapidly down and slow of oxygen to support the combustion. So all the combustion we did was underflow, and it is great to see the spreading of the flame in weightlessness in the absence of convection in the presence of flow. And this will give us a lot of information about the design of the space system in the future for spacecraft, in particular for manned spacecraft in order to prevent dangerous combustion of elements of the spacecraft in case of fire. If I may interrupt just a second. As we are talking about other experiments that we have here on board, apart from the tether satellite system and the interspace microgravity pilot, I would like, frankly, in Chang here, which is the pay dot commander, to talk about another very important experiment that we have here on board that concerns medicine. One of the experiments that we have in the crew cabin is a very small contribution from the countries of Latin America to investigate the effects of crystallization of certain proteins with an aim to combat a very serious disease in Central and South America called Chagas disease. And we carry with us certain proteins, which we are crystallizing right now over the course of our mission, and we will bring those crystals back to Earth to be analyzed and studied so that they can actually determine the structure of this very serious disease. Okay, and now? Lots of camera activity on board on a long flight. We can't carry enough half of that magazine for the whole flight. So we have to reload film from small cassettes into the magazine, which involves working inside a dark bag. And that's what I'm doing here. And still, that should hopefully keep us going for the rest of the mission. We're having a little trouble with this cable here. So I'm contemplating what's the best way to go about fixing this cable so we can use our camcorder interface to get you better pictures coming on down. The ground said be ingenious, and I'm thinking about it. If you're ready for the rotation maneuvers that we didn't do, of course, commanders love to turn on all the primary jets. To maneuver an orbiter, we'll certainly go ahead and take it. Okay, at 3D, we're working on this for the last four samples. And Dracke was helping, you know, with the procedures. Basically, I'm stating the procedure on the basis of the last message that we received. Well, that experiment apparently needs three people because you've got to have one person pushing the button from the camera and setting the 80 kilometers so the flames fire at just the right moment. So that's what I was getting to do here to help those guys get the experiment done. No more samples for 50, so we are looking for other things to burn here. Maybe portion of the slide data files that we don't use or something like that. We have lots of messages coming up and going down between the orbiter and the ground. We have a KCA, which is the computer I'm working at, and I'm just checking the mail and telling Scott that he forgot his discount. We got cutters there. And one of my all-time favorites here is the stripper on this side. Thanks again for having fixed this right up and it's going to save us a lot of hassle getting videos down to you guys. Okay, they've been listening and watching this. If that thing is missing in the next inventory, they will know where to find it. Maybe for such a good job, they might give me one as a present. Columbia is, she is going to kill me, but you ought to know it's Darina's birthday. She's 35 today. Yes, sir. Thank you very much, Muratio. Hello, Columbia. Go ahead. It's Darina. I'm very happy birthday. I can't think of a better bunch to spend it with. Columbia, could you put a candle in the glove box? Too, we can dig up story. And Columbia Huntsville, I see that, and thank you very much. This? Yeah, we're getting a great picture. I just wanted to wish you a happy birthday from me. Thank you very much. That's much appreciated. For the birthday you've had better things to do, but certainly this one you'll remember. Most definitely.
