The study is conducted by the Utah State University Materials that contamination can lead to catastrophic charging effects under certain circumstances, little direct information is presently available on the effects of sample deterioration and on emission properties for materials flown in space.

Approximately 145 samples will be mounted on panels on both the ram and wake sides of the ISS. They have been carefully chosen to provide needed information for different ongoing studies and broad cross-section of prototypical materials used on the exteriors of spacecrafts. Characterization measurements include optical and electron microscopy, reflection spectroscopy, resistivity and Auger electron spectroscopy. In addition, studies of the service life of composite and ceramic materials of the ATK Thermal Protection Systems and Lightweight Structure Systems will evaluate chemical and mechanical properties as a function of depth from the AO and UV exposure surface. This poster will chronicle the design, construction, and assembly of the sample holders and also the characterization of each of the material samples.

With a design based upon Robert Milikan's oil-drop experiment, this experiment is designed to observe the interactions of a lunar dust simulant without the conflicting effects of a dominant gravitational force. The dust particles will be charged by means of a lamp capable of photon energies necessary to emit electrons by the photoelectric effect. In the presence of an axial electric field, the photo-electrons and charged dust will be attracted to opposing sides of a capacitor and the net charge over time as well as physical trajectories of the particles can be determined.

Low Earth Orbiting Photographer (LEOP) Cube Satellite http://digitalcommons.usu.edu/gas_post/9 http://digitalcommons.usu.edu/gas_post/9 Wed, 04 Apr 2012 08:55:54 PDT The exploration and study of space is critical for the future of our society, but the opportunities for educational institutions to get involved in space research have faded dramatically in the last decade with the retirement of the space shuttle program. The USU Get Away Special (GAS) team is designing a new, low cost solution to space research, CubeSat (Cube Satellite). This small satellite, with a volume of approximately one liter, will have a high resolution camera directed at earth, and students will be able to request a picture of their area when the satellite flies overhead. In this way, students will have an eye-in-the-sky to help them be a part of space research. The GAS team expects this project to increase interest in space research and provide an affordable solution for future projects.

Development of Optimal Bubble-Seeding Microheaters to Study Nucleate Boiling Heat Transfer in Microgravity http://digitalcommons.usu.edu/gas_post/7 http://digitalcommons.usu.edu/gas_post/7 Fri, 23 Sep 2011 10:33:27 PDT Heat management is a critical issue facing engineers of spaceflight systems. Nucleate boiling has high heat transfer rates, but further study is needed to apply this method effectively to a heat transfer system in a microgravity environment. The USU Get Away Special (GAS) team is conducting a series of experiments aboard NASA's "Weightless Wonder" aircraft to further understanding of nucleate boiling activity in microgravity. Two specific focuses of the current experiment are determining optimal surface geometries of microheater arrays designed to induce nucleate boiling and constructing a lighting and video system to spatially and temporally resolve the anticipated jets of fine, high-speed bubbles. As we use these systems to collect and connect data, we expect to gain an increased understanding of the conditions, parameters, and applications of nucleate boiling in microgravity.

Effects of Micro-gravity on Thin-Wire Subcooled Nucleate Boiling Dynamics http://digitalcommons.usu.edu/gas_post/6 http://digitalcommons.usu.edu/gas_post/6 Sun, 18 Sep 2011 14:05:16 PDT Nucleate boiling is a highly effective means of transferring heat, and as space exploration begins to reach farther from Earth, efficient heat management systems in microgravity are becoming increasingly important. In the summer of 2010, members of the USU Get Away Special (GAS) team flew aboard NASA’s Weightless Wonder in order to study the effect of various system parameters on nucleate boiling heat transfer behavior in microgravity. This one dimensional study of boiling used a new geometry never tried before and concluded that heat transfer rates during boiling in microgravity do not significantly differ from those observed on Earth. These results will allow for a more in depth study of the phenomenon and hopefully lead to the development of a two dimensional heater with important practical applications.

A Systemic Study of Nucleate Boiling http://digitalcommons.usu.edu/gas_post/5 http://digitalcommons.usu.edu/gas_post/5 Sun, 18 Sep 2011 13:51:58 PDT Nucleate boiling is a heavily researched form of heat transfer due to its associated high heat transfer rates. Applying two-phase heat transfer to space systems would allow these systems to become more capable, efficient, and compact. However, a fundamental understanding of boiling dynamics in the absence of buoyancy is yet to be developed. This study intends to analyze the effects of gravity, power input, and surface geometry during successive periods of microgravity provided by NASA’s “vomit comet” through the Reduced Gravity Student Flight Opportunities Program.

Six members of the GAS team will fly in a specialized jet which will simulate microgravity where the experiment can be performed in 30 second intervals. The purpose of the experiment is to determine the properties of nucleate boiling of water in weightlessness. The experiment will be monitored with temperature sensors, accelerometers, and high definition cameras and the results will be analyzed frame by frame. This will provide important information related to the dynamics of heat transfer using thin wire heating elements in microgravity. Under these controlled conditions, the boiling dynamics will be under specific scrutiny. Additionally, other observations related to varying power inputs and the effects of alternate surface geometries of the platinum wire will be made. The GAS team flies June 17-26, 2010 at Johnson Space Center, Houston, TX.

Although this experiment is not designed to provide a dust mitigation strategy for lunar regolith, an increased understanding of the charging properties of silica by means of the Get Away Special Team’s experiment benefits the scientific community.

Space Research Projects for the International Space Station http://digitalcommons.usu.edu/gas_post/2 http://digitalcommons.usu.edu/gas_post/2 Sat, 17 Sep 2011 14:57:28 PDT Space Italian Dressing Experimental Setup (SIDES) examines the dynamics of fluid segregation between fluids of differing densities. While in space the fluids will not undergo buoyant or convective forces, thus isolating the affects of separation due to density and molecular forces. The experiment will serve as an outreach experiment in addition to gleaning scientific data; mixtures are a topic of study in the 5th grade curriculum.

The objective of International Paper Airplanes in Space (IPAS) is to excite children about space research by giving them a chance to take part in it. IPAS includes collecting paper airplanes made by elementary-school students from around the world. The airplanes will be sent to the International Space Station to determine the effects of microgravity on paper airplane flight. The data will be recorded, collected, and then disseminated.

Research on the Effects of Microgravity on the BRazil NuT problem (REMBRANT) examines the affects of inertia on granular separation. The experiment includes two to four different bead sizes in one container that will be shaken and recorded to evaluate the ensuing collisions. Because of minimized gravitational effects, the granules will not be subject to buoyant or convective forces.
