Metal Solidification Under Microgravity

March 23, 2014
From the European Space Agency: An X-ray recording of metal solidifying under microgravity. The video was recorded on a Maser sounding rocket. In under seven minutes a small furnace was used to cook a metal sample to 700°C turning it liquid before it was frozen inside a cooling chamber to solidify into crystal clusters. An X-ray camera captured this dramatic experiment for analysis.
