The occurrence of autowaves at the interface as a result of a first-order phase transition had been examined. The linear analysis of a system of the equations for a liquid which contains two components shows that a phase transition at the interface can give rise to autowaves. A spectrum of these autowaves depends on parameters of the system. For a special case of the system parameters an analysis is made of the dependence of the spectrum of autowaves from a temperature gradient the interface. We show that as a result of a interface instability in the bulk solid phase there are various periodic structures of distribution of the component concentration. Surfaces of equal concentration for the spectra of the autowaves are built. A qualitative and quantitative comparison of the numerical calculations with experimental data is made.

The National Aeronautics and Space Administration (NASA) has been supporting research in microgravity low temperature physics tor about 20 years. In the last 10 years the program has seen srgnrhcant growth rn the number ot funded investigations and in the breadth of the research activities being pursued. Currently, flight experiments are being performed exclusively on the Space Shuttle. For the future, a cryogenic Space Station facility is being developed by the Jet Propulsion Laboratory and industrial partners to support the microgravity needs ot the international scientific community. The facility will be attached to the Japanese Experiments Module’s Exposed Facility and will operate with a 6 month helium cryogen lifetime. Flights of the facility are planned at 2 year intervals starting in 2003 with each flight accommodating multiple scientific experiments. Capabilities, conceptual designs and development plans for the facility are discussed along with a summary of potential near term flight candidate experiments.
