 Brent, we're looking at both of you there on the flight deck, and it's had your discretion. Okay, it's okay. We'll bring them on now. If you want, we can power them down and then the DAT cream and power them back up. But if we're not going to take any more data, it just, it doesn't seem necessary. Roger. We copy. We're looking at the, that the GPS... A little bit more information overload. The disk has 26.5 megabytes available on 700-14. Okay. We copy. We're just puzzling over your call and wanted to make sure that we're configured properly for the GPS INS troubleshoot procedure that's timeline little before 2300. Yeah, I'll bring them. I'll bring 700-12 back up. We're in the chamber. This is John Baja. We have you loud and clear, John. Thanks for the call. We also can see you on the monitor in front of us. You asked me what did I think about the, how did that go with the BTS and the cartilage? Is that correct? That's my copy of that, John. Well, first of all, a tight bearing and a broad really shows the value of long duration. So on the ground had done a fantastic job designing it and everything and tested it on the shuttle. We were to find through the whole system and finally get into the vessel. And when I saw the bubbles first but then the people on the ground as before we, I mixed a new bag and we just had to get the human being involved. So that experiment as it turned well as human involvement. I'd like to again, I'd like to echo congratulations to you. My question is dealing more with on the psychological aspects of long duration. We're also doing some evaluation, psychological evaluations for our tests here. I was wondering, were there any, some things that you found helpful in making your stay more enjoyable for your, for the duration of your mission? One minute. Yes, I understand. You know, you're talking about something now that I think is crucial to a long duration flight be it a flight on a space station with an international crew. And I stress that international crew or a flight to Mars with an international crew. When you put people together who are from different colleges, their primary language, you even add to the psychological problem. For example, the four of you, your laboratory on the ground. And in fact, I think you could think of next time you do something like this, try nationalities together, language real well, because that introduces, I think, another element of psychological. And in my case, I had trained with two ready for a year and a half. And then unfortunately, a week before their launch, one of the people held, but so they had to change the crew. So I flew with a completely different two Russians than I had even trained with, which even added more to, I think, some stress in the first. So, but you're onto something that's very, very important, parameters, and we really need to think about it in the future with our international space station. For example, we have two Americans, two Russians, a European and a person from, say, Japan, owned by themselves and don't have a friend from their own culture. I think we're going to even have a little more special kind of problem that we need to pay attention to. Test, I was wondering if you had any experiences or interactions with the mere life support systems that you'd like to share with us? Absolutely. You know, you're right on at those life support. And I would say a couple of things on that that I noticed working with my two Russian colleagues, Valerie and Sasha. First of all, those systems at a deeper level than I remember I knew the ecosystems here on the shuttle. When you're able to clean a vehicle up on the ground as we do and then go into orbit and stay for two weeks and come home and clean it up again, that's one kind of level of knowledge. If you're going to go up there on our new space station, you need to go to a deeper level of knowledge and into that deeper level of knowledge because when something goes wrong, maybe the spare and take a small component out of this bulk and then actually fix it and then put it back in the box. That's the type of training we're going to have to do. And I saw a lot of that during my flight on Mir. Houston lent us for a job brought with him and we put them in PTCU-1, which is a five-degree C container. They're not supposed to be frozen, so we didn't put them in Leslie. We just want to make sure that you and the Biorack folks know that that's where they are. See them and concur. Thanks. Houston, for CMRF, we have a question. Do you want all of our little data runs here with only one CMO or we'd love to use two people to restrain the patient? Marsha, we'd like to use two, if possible. Okay, the first one went dead with, of course, a record time of 55 seconds of getting John restrained and now we'll do it with two. Space habit minus FO 12, step 12 is complete. And we copy, thanks. Houston, very impressive. We're one minute to the ZOE. We'll pick you up at 2233.
