Zero G Mass Measurement Device (ZGMMD), Phase II

The Zero Gravity Mass Measurement Device (ZGMMD) provides the ability to measure the mass of samples in a microgravity environment, like that found on the International Space Station (ISS). One of the primary measurements often taken during science experiments is mass. This is even more relevant in biology, where mass is often one of the key measurements taken for analysis. During the Phase I effort, a ZGMMD prototype was developed, tested, and demonstrated the feasibility of a means to determine the mass of samples less than 1kg, without the use of earth's gravity. The ZGMMD's innovative way of determining the mass, of low mass objects, in microgravity environments has been shown to be feasible, and effective. The Phase I prototype has shown to be able to provide great mass measurement capabilities, exceeding the Phase I requirements, specifically in accuracy and precision.
