Abstract The Isothermal Dendritic Growth Experiment (IDGE), to be performed on three of the USMP flights, starting with United States Microgravity Payload-2 (USMP-2), is designed to provide microgravity data on dendritic growth for a critical test of theory. Ground based test data using succinontrile (SCN), from both a flight capable growth chamber and a laboratory growth chamber, are compared to theoretical estimates of dendritic tip radii and velocities at several microgravity levels. The comparison shows that the data from the flight chamber are consistent with the historical data and that dendritic growth in a microgravity environment of 10−3 g0 or lower should exhibit significant differences from the dendritic growth of SCN at go.
