SOLIDIFICATION OF A LIQUID METALIC BRIDGE IN MICROGRAVITY DURING A FREEFALL FROM A STRATOSPHERICAL BALLOON

摘要

Within the so called earthly infrastructures to create Microgravity, there is one that is based on the capacity to elevate a Capsule with Stratospherical Balloons that reach great altitude in order to release it in free falling. The Argentinean Laboratory of Microgravity located at the Comahue National University, has designed and built a Capsule to conduct Experiments in Microgravity by means of Stratospherical Balloons that would reach up to 25.000 meters high. In function of the release height, the drag coefficient of the Capsule (Co) and its weight, it is possible to create between 10 and 20 seconds of Microgravity with values that go from 10~(-1)G up to 10~(-4)G.
