 for another exciting day here in the space business. For right now though, we're going to timbu up a fuel cell purge for you. This is Mission Control Houston. This morning's wake up call. The Air Force song by the United States Air Force Academy Cadet Chorus. That for pilot Steve Lindsey who is a major in the Air Force and Commander Kevin Kriegel formally of the Air Force. This is USMP4 science operations control Huntsville. Science activities aboard the space shuttle Columbia continue to go well this afternoon. A new growth cycle is underway with the isothermal dendritic growth experiment. The study is designed to improve metals used in automobiles and jet engines. In the experiment, our materials are melted and re-solidified to observe the growth of dendrites. You're looking now at live video downlinked from the shuttle Columbia of the IDGE experiment as the dendrite grows in space in the microgravity environment. IDGE's lead scientist, Professor Matthew Koss of Rensselaer Polytechnic Institute in Troy, New York, says the science team is repeatedly performing growth cycles at the same super cooling. This allows researchers to obtain the best science data set possible for later analysis. And the growth cycles continuing with the IDGE experiment on board the space shuttle Columbia. Also today, very good reports from the science teams, both with Mephisto and another furnace on board Columbia, the advanced automated directional solidification furnace. These views showing some of the payloads in the cargo bay. These payloads, many of them have been operating throughout the mission, mounted in canisters in Columbia's payload bay. They include various technology experiments studying new technologies that can be used on future spacecraft. Among those are a study of a heat pipe technology that can be used for cooling, a passive cooling system that would include no moving parts. Being studied for possible use on future satellites, that experiment is called the loop heat pipe experiment. It's sponsored by the Center for Space Power at Texas A&M University in Corpus Christi, Texas. Also another experiment in the cargo bay along with the heat pipe experiment is called the sodium sulfur battery experiment. Looking at how sodium sulfur batteries can operate in weightlessness possible source of battery power for future spacecraft. Other experiments in the cargo bay that have been operating throughout Columbia's mission include the turbulent gas jet diffusion flames experiment. That experiment seeks to understand the characteristics of turbulent gas jet diffusion flames in weightlessness. Training session underway as we see Jerry Ross here is to evaluate the handling characteristics of the satellite. He and his colleague Jim Newman have been passing the mock-up of the Spartan back and forth to understand and get a good feel for its handling characteristics. The Spartan actually weighs in at about 1,200 pounds of course in space with microgravity that it really has no weight but its mass is still there. So it is the prudent thing to do to understand the handling characteristics of the Spartan satellite. So they'll continue this training session for another couple of hours in the water tank which is near the Johnson Space Center here in Houston. And this wider view gives a better idea of the size of the satellite in relation to the two astronauts. And again in this view Jerry Ross is on the left and Jim Newman is on the right. They are distinguishable by their air hoses which obviously are not used in space but underwater they are and Jerry Ross is red and Jim Newman is white. So the second goal is to examine the various tools used by the station and the crane. Today I would like to show you the space that we can go through. The space on my right hand is the space that Winston can go through. And the space on my left hand is my space. You can divide it into four parts. The other part is the helmet part. I think you can see the glass part too. The helmet part has a helmet light. So we can use it at night. When the sun is very bright, we can use a visor which is very cute. The lower part of the helmet is the body part. The body part has various tools like this. The back part of the body part has a backpack. Inside the backpack, we need to operate in the air. There is a oxygen tank. There is also an anti-aircraft device that adjusts the temperature and humidity in space. In the lower part of the body part, the lower part of the helmet is my leg part. And the fourth important part is my hand bag. The Carpenter Carpenter Airlock is outside the video. Please throw my handbag at her. Carpenter, please throw my handbag. Thank you very much. In space, it is so easy to do things. This is my handbag. Compared to my handbag, it is twice or three times bigger. The handbag is like this. You can put it in the same part of the handbag. The second part of the handbag is very thick and hard to move. When you choose your handbag, it is important to choose your handbag. Otherwise, it will come back to you immediately when you use your handbag. We use various tools. Today, I will show you a power tool that you can use as a tool. Carpenter, please throw my handbag. Thank you very much. This is the power tool that we use in outdoor activities. If you look at it, it is a electric driver. There is a motor in this part. And then, this part of my handbag is in the battery. By using this power tool, I can stretch and tighten the hands of the crane. You can do a lot of rotation and torque. So, it is very easy to do the opening of the boat. Next, Winston and I will open the airlock that is behind me. Please come to outdoor activities. Thank you very much.
