 Also, in addition to continuing work on the mid-deck of Columbia mission specialist, Mike Lopez-Alegria, will also take some time to exercise today on the bicycle ergometer that will be set up on Columbia's mid-deck. Mike Lopez-Alegria is also the astronaut on the blue team. Can you verify that that is Romeo 10 Echo that you're looking in? Copy that, Fred. SACA insertion is complete. Copy that, Fred. 5.14. For Katie, we did not hear that. Do you mean the gaps in TBC2? Affirmative. Talking about closing and the two underneath that. That is the termination fluid. The top plunger and the center plunger would terminate, so we do not want to close that small gap. Move cap on tape from the isolator from both ends. Let me see it on one end. Also, upcoming for the crew in about 20 minutes, one of the final activities for the blue team will be a test of a new system being flown for the first time on a shuttle aboard Columbia on STS-73. That system, a system that allows ground-to-air television to be sent, television from the ground to be sent up to the crew, and a vice-versa two-way television essentially for two-way conversations. Again, the first test of that system, which is being flown as a test objective on this flight, will be taking place in just about 20 minutes or so. The pre-recorded uplink transmission of the GATV. This is mission control Houston that, again, has been a test of ground-to-air television uplink to Columbia, that equipment being flown for the first time on this flight. Again, allowing scenes to be sent up to the shuttle from the ground for mission control. That segment, just a test segment with several different test patterns and several different highlights from past shuttle flights, just methods of illustrating this shot now is live from mission control of flight director Brian Austin and spacecraft communicator Carl Mead. Again, being sent up to Columbia as well. Again, Columbia, the first shuttle to fly with this equipment. It's a test objective. Several other tests of the ground-to-air television capability will be performed throughout the 16 days. Columbia spins in one bit. And we can see payload specialist Al Sacco there going into one of the stowage containers on the ceiling of the space lab module. There's a great variety of apparatus that has to be stored in special areas of the module or in the shuttle mid-deck in lockers. And all of that comes under the heading of stowage. It's one specialized aspect of preparing for a shuttle mission is just planning out where you're going to put all the things that the crew will need to get access to for launch and landing. Many of the things that they'll be using during the course of the mission are put away in particular areas so that they obviously, so that they aren't just floating around loose during those launch and landing periods. And so now we get a better look with Sacco in the foreground pulling down one of those stowage areas. It's like a drawer that in this case though comes down vertically from the ceiling of the space lab module. Space lab hunt still with words on DPM. Yes, Kathy, DPM would like you to manually tune X to start with and see what happens with that. This is in the AstroCulture Plant Growth Experiment System and it's the first opportunity that the science team for that experiment is having to take a look at. Unknown sources for the next several minutes. This is their first opportunity to see get a little insight into the status of the plant growth inside that facility which is intended to potato seedlings to grow in microgravity conditions. The principal investigator team here in Huntsville advised that they're elated at the way things look inside the facility. It's a rather close up view showing the tops of the leaflets. There are about three of the small potato plant leaflets that are visible in this very detailed view. The tubers that are the actual substance of the potatoes, the source of starch, are buried or obscured by the leaflets but the science team members are able to judge the status of growth from what they see in this video and they've indicated that what they see tells them that the plants so far at least are maintaining the vigor that they would like to see. And of course all of this is being done as preliminary steps to starting to go into the actual science work with liquid drops in the chamber. And Kathy we'd like you to go ahead and move the injectors in please fully inserted. And now we can see those injectors coming in and contacting the small solid sphere, immobilizing the sphere. This is another of the steps. That's affirmative Kathy we'd like to see that. We get a pretty good close up view of the liquid injector systems here in this video that's coming down. They are one of the portions of this system that have been improved since the first flight on STS-50, USML-1. The injectors and tips have been redesigned. This is Base Lab Operations Huntsville where we are currently receiving downlink video from inside the chamber of the single locker protein crystal growth experiment. This particular experiment is crystal growth by liquid liquid diffusion. For this experiment the protein crystals are grown in four handheld diffusion test cells which are often referred to as HHDTCs. Each one of these contains four test cells and by diffusing one liquid into another crystal growth is accomplished. In this particular experiment the two different liquids are brought into contact with each other but they are not actually mixed. Eventually these fluids will intermingle with one another what is often referred to as diffusion through the random motion of molecules by gradually increasing the concentration of the precipitate in the protein solution. This causes nucleation of the crystals.
