 And once again, we have live downlink from... We copy Susan and you can proceed and the path card was good. This is Space Lab Mission Operations Control. We are now receiving live downlink from Orbiter Columbia. This view coming from within the Space Lab module. Go ahead for the daily status check. Put it at one. Once again, we're continuing to receive live downlink from the Space Lab module inside Columbia's cargo bay. And the view we're seeing here is coming from a camera that is mounted in the aft end of the Space Lab module. This camera is looking forward in the module and so we are seeing the right hand side or the starboard side of the Space Lab module. And just to point out a few of the things we're seeing in this view, if we look at the left hand most part of the view here, we see the two yellow boxes and what those are is that is where the Space Lab VCRs are located. Those VCRs used to record all the video that comes from these cameras that we are seeing. We only get portions, small opportunities to get this video downlinked and so those video recorders are used to record all the video that those cameras take. And then moving more just to the right, we see the bubble drop and particle unit experiment. That again is one of the facilities that uses the crew to load the different test chambers and initiate the test runs and then the experiments or the test runs are then remotely commanded to and operated from here on the ground at Space Lab Mission Operations Control. And further to the right almost directly in the center of your screen in the green colored rack is what is, that is where the astronaut lung function experiment is located. Again that experiment is studying the effects of weightlessness on the human pulmonary system. And just on the bottom left hand side of your screen you can see one of the crew members, this particular one being payload specialist Bob Thurst who is performing activities in the torque velocity dynamometer which is located in the center aisle of the module. Dr. Douglas Watt of McGill University in Montreal is the chief scientist behind the tree experiment. He has devoted his career to trying to understand how the vestibular system or our inner ear's balance and orientation center how it functions and how specifically it adapts to a weightless environment. The idea for the torso rotation experiment first came to Dr. Watt several years ago when one of his colleagues suffered an injury that required the wearing of a rigid neck brace. The colleague mentioned to Dr. Watt that after a few minutes of walking around the laboratory began to develop symptoms of nausea. Torso rotation is a term that we use to describe a person who rigidly fixes their head to their torso such that when they have to turn their head to the right or to the left they have to turn their whole torso as well. Torso rotation is an example of an abnormal motor strategy in which the subject concentrates on a body frame of reference rather than the external world. And this causes us to suppress the normal way that our vestibular apparatus in our brain likes to operate. Another good example of suppressing the normal way that our brain and vestibular system likes to operate is someone who is trying to read a book inside a car that is moving down a twisty country road over the place of trying to focus on it to make reference to the world that we see outside the window. And as you know several people who try to read books inside moving cars become motion sickness as well. What is interesting to Dr. Watt is that astronauts tend to inadvertently develop a torso rotation motor strategy as well during the first couple of days of space flight. And we probably do this to try to minimize our symptoms of motion sickness but in fact we might be exacerbating the symptoms. For Dr. Watt's torso rotation experiment study on the life and microgravity space lab mission we are going to be measuring our eye movements with special electrodes that we apply to our face with a special velocity rate center that we rigidly fix to the top of our head and also we'll be measuring our torso movements as well with a special backpack accelerometer which is fixed to our back. After the flight is over Dr. Watt is going to compare our eye movements to our head movements and our head movements to our chest movements and he'll be looking for any evidence that we might have adopted some torso rotation motor strategy during this flight. We'll be doing this experiment once early in the mission we've already done it exactly towards the middle of the flight in a couple of days and again towards the last day or two of the space mission. If it turns out in fact that we'd have adopted torso rotation motor strategy during the flight which might cause symptoms of motion sickness that it would be relatively easy to train future astronauts to avoid this type of motor strategy or to pre-adapt them to the atypical movement environment in a ground based laboratory prior to flight. Well that's what the torso rotation experiment is all about. If you see us in downlinked video over the next few days bearing strange looking apparatus on our head or on our chest you'll know that we'll be just checking out to see whether or not we are trying to unconsciously suppress the normal way that our vestibular apparatus likes to operate. Well that's it today from the space shuttle Columbia. Tune in tomorrow to learn about one of the other exciting LMS investigations. Goodbye. Now in view from Columbia the outer banks of the Carolinas Columbia moving out to above the Atlantic Ocean.
