 This television is from Columbia. This television, a view of the isothermal dendritic growth experiment, experiment actually located in Columbia's cargo bay as part of the United States microgravity payload. The IDGE experiment, as it's called, studies the crystals that form metals on Earth, those crystals called dendrites. Dendrites can be formed much more purely in weightlessness and in much more pure form than they can in Earth's gravity. Thus, hopefully providing scientists a better insight into the basic structure of metals. Columbia, for Clark Park. Go ahead, Casey. Focus right now, as you see. And I think you can see what's happening to the particles, not better out here. And you can see sometimes the particle reaches the interface. It just joins the collection, and another collection gets dislodged, goes in a very different direction, so you lose track of the particle altogether. We copy that, Casey. I appreciate your focusing on these different levels. That's going to help the team out. I think it'll make it easier to measure the particle sizes. Oh, sure. This is Mission Control Houston. This view coming from one of Columbia's payload bay cameras, looking down on the Earth as the orbiter flies. 152 nautical miles above the surface of the Earth, passing over the central portion of Africa.
