 that you were starting at six o'clock. We're going around clockwise to show you the markings, and it is our perception that there was no movement of the hatch when we repressurized back to 14.7. Thank you, Tammy. In Columbia, as you saw, we walked around slowly throughout the entire hatch perimeter. We can't detect any displacement laterally, and we certainly see no gross motion as measured against the markers that we put around the door yesterday at 10-2. So we don't have any deltas to show you any other things that you'd like to see. OK, we are full closed. That is in the direction of closed. And now I'm going as far open as the handle will go easily. And now I'm going to push those extra couple of to the left impact to the closed direction. Yeah, that gave us a very good idea of what you had told us in words a couple of days ago. So we really appreciated that. And that concludes our requirements for downlink of the hatch. Thank you very much. That was excellent. I did the first series here on the tape, and we're starting out with the B-3 setting on the power tool. It was very easy holding onto the handrail of the hatch minute by the tool through the B-3 and B-4 settings. There was only a flight amount of torque applied when the fastener went all the way down to the hard stop. We copy. Watch us run through the series. But the basic finding at B-5 was that the body position was disturbed quite a bit by the B-5 hard stop force. And B-6 and B-7, while attempted, really swung the body around to the point where the tool was hopping off the bolts, or you could not hold your body position. In Houston, while we still have a few minutes of KU, I can just say briefly that we all found very similar results that the B-3 setting corresponding to 5 foot pounds was certainly acceptable, as was B-4. But when we get to B-5 setting of 15 foot pounds, that's a fair amount of force to react through your wrist. B-6, again, we got low torque readings indicating that we let go of the trigger early. And if we have enough time in this KU downlink, you'll see when I get to that setting, my body will get spent around much like Tom's did. One thing to think about when you're setting up your test is, as Tom mentioned, was that we will be on umbilicals. A handrail position is very important. This handrail position is not ideal. A handrail on the floor would have been a little bit more comfortable when reacting to higher torque. And we're wondering if we have enough clearance in the mid-deck, in a suit, without our legs contacting the walls and biasing the data. If you're truly looking for us to hold the tool and react all that torque through the wrist and not use our body in any way as previously briefed before we flew. We copy all. My data came out the same as through 15 foot pounds. Went very well beyond that in this particular non-suited environment. Not reasonable. I intuitively think that this is going to go a whole lot better when you're suited. Because instead of having 160 pounds of body inertia, you have about 480 pounds to help stabilize the body when the tool reaches its final torque. I also intuitively think that a gloved hand is going to hang onto the pistol grip a lot better than the bare hand does. And there's also a lot more strength and stability, at least stability, in the wrist and arms of a suit. So I intuitively think that this is going to go a lot better in a suited situation. We copy? Base Shuttle Columbia, astronauts Tammy Jernigan and Tom Jones are with us. The two of you, thanks for letting us be with you in the middle of your day. We can't start without talking about the fact you didn't get to go outside and conduct your space walks. Everybody on Earth is talking about it. What went through your mind, Tammy, when you tried to turn that hatch handle and it didn't work? I was certainly surprised that the handle would not rotate as I had trained for it to rotate. Certainly was frustrated. And so we tried to rotate a little harder and actually ended up working for a couple hours trying to get the hatch open. So we were certainly disappointed, but also thinking that there was a lot of time left in the flight. And we knew that the ground team and the crew would work hard together to perhaps think of a work around. Tom, you got into the act after that in that very craft airlock with Tammy. What did you think the problem was? Well, initially I just thought we had a sticky hatch. And the fact that Tammy's initial rotation wasn't able to free it up was just an indication that we'd have to put a little bit more elbow grease into it. She certainly tried and then asked me to give it a shot that I wasn't able to budge it either. And we were both putting out about the maximum force we ever tried to put into mechanical systems in our water tank training back in Houston. And so at that point I started to think that we had a jam of some sort that our strength wasn't going to be able to overcome. And so during those two hours in the airlock while we juggled our bodies around and tried to find a more mechanical advantage, I was also thinking about perhaps coming back the next day and trying this with some more strategy. What were the two of you trained to do? I guess let's start with Tom on this one. In case you were able to get the airlock open, but then you couldn't get it to seal completely when you were finished with your spacewalk. Well, we had physics working for us in that case. Once we got back inside the airlock after an EVA, the airlock glides up against its seals with a very easy motion and turning the crank handle nearly engages some mechanical dogs that hold the hatch mechanically tight. But if we could get it close enough where it would actually touch the seal, as soon as we got air in from inside the orbiter cabin and that air pressure would slam that hatch shut up against the seals and it would stay closed no matter how strongly we pulled on it. So we were pretty confident that we wouldn't be in a bad situation. But there's always a potential in trying to get our way out mechanically with some of the tools we have on board that we might damage or warp the hatch in such a way that those seals could be damaged. And I think that's the conservative approach that the shuttle program has taken here. They didn't want to damage the hardware for the objectives of the CDA, which could be rescheduled and thrown on a later flight. Yeah, that's the question that a lot of people have now. What are the two of you gonna do about your training as a space station construction workers since the best place to do that is out where the space station would be outside in the cargo bay or very near it? What do you think it's gonna mean to you and to the overall program? Does the failure of the hatch to open slow down space station construction even by a little bit? I certainly think there was interest in conducting these two EVAs. There was a lot of time and effort put into building the hardware and orchestrating the test plan so that we could test all this hardware and our concepts for station construction. And so certainly it is a bit of a setback. However, there are setbacks in a program as ambitious as NASA's space program and NASA will figure out a way to get the information they need to successfully construct the station. This hardware may fly on a later flight or they may use some more extensive ground testing to get the information they feel they'll need. But they will certainly take the steps to ensure that we have enough knowledge to have a successful station construction and maintenance program. Sure, well, the two of you. God, let me just add that we spent the last 10 months training extensively for these two space plots. And a lot of the work that we did underwater in Houston and on board the weightless training aircraft down there as well, we spent validating the approaches and the techniques that we would use here at orbit. And to a large extent, we have a lot of confidence in those techniques because we worked so hard on them on the ground. So I think the final icing on the cake and the final confirmation here at orbit would have been really valuable to us. But certainly we've learned a great deal in the last nine to 10 months just in the developmental and practice work we've done in training for the space walks. Yeah, the two of you are making the best of this course. And we've been watching you test some of the space station tools you're going to be using when you build the station later on. How do the tools work in the test that you've conducted on them over the past couple of hours? Well, the ISS power tool has performed well and as expected during the test we did on the mid-deck. And we were able at least to fulfill some of the objectives for the flight by doing the power tool checkout and then sending that data down to the ground. All right, Tammy, I've talked to Tammy Jernigan and Tom Jones several times over the past couple of years. And you know, maybe it's my question. Maybe my questions are bummer questions for you guys. But the two of you, despite the fact that you're always optimistic and almost bubbly, seem pretty much subdued as we talk right now. Am I right about this or is it my question leading you down a very serious and somber path today? No, I think certainly that we are feeling some combination of disappointment at the failure of the hatch but yet pleasure in being part of this mission that's been in every other way very successful. And we're both technical people and so when you ask us a technical question, you get a technical answer. I'm glad to see some smiles from both of you. Tom, any final comments? We've only got about a minute left. Well, disappointment naturally comes into our feelings and I hope for better times on future missions where I'm assigned to a spacewalk. I'll be an optimist about that too but you can't take away the fabulous nature of this experience. And personally last night, even after our EVAs were canceled, I spent an entire night orbit of the earth looking down at thunderstorms and out at the southern constellations and watching the lightning flicker off the surfaces of the orbiter. And that's such an experience that is unreachable on the ground that I'm very privileged to be here and I have no basis for complaints.
