Videos: Space to Ground ISS report + Molten metal levitator

The latest NASA Space to Ground report on Int. Space Station activities:

Here is a video about an instrument used on the ISS to levitate metal while it is melted and then rapidly cooled. Dr. Douglas Matson of Tufts University is interviewed about

the Electromagnetic Levitator, a piece of physics experiment hardware operating in the station’s Columbus laboratory. The EML is a furnace that can heat metals to more than 2000 degrees Celsius and then cool them rapidly, and by doing so in a weightless environment—with the samples suspended in mid-air—allows scientists to more clearly observe some of the complex core processes of physics.
