Electron Yield Of A Carbon Fiber Composite, Matthew Robertson

Utah Space Grant Consortium

As electron yield models continue to evolve and improve, a study of carbon fiber materials was conducted to try and understand more complex nanoscale structures and their influence on electron yield.

Using Geologic And Geodetic Analyses To Define The Location, Slip Rate, And Geometry Of Off Fault Deformation, Hidden Spring Fault Zone, Southern California, Rebekah Riemann, Andrea Donnellan, Jay Parker

Utah Space Grant Consortium

A strain deficit of about 10 mm/yr exists across the San Andreas Fault system on the boundary between the North American and Pacific plates. We investigate the role of the Hidden Spring Fault Zone, east of the Salton Sea in Southern California, and related structures in accommodating some of this slip. We compile data from historic and current aerial and satellite imagery, coupled with UAVSAR and LiDAR data have allowed us to identify and map hundreds of new fault segments in the region. Where possible, we correlate some of these data with geologic evidence for the faults. These data emphasize …

Applying Real-World Learning Through Amusement Parks To Help Teach The Upcoming Changes To Utah Core Standard, Phil Lundgreen, Amanda Otterstrom

Utah Space Grant Consortium

To assist educators in satisfying the Science with Engineering Education (SEEd) Standards the Utah State University (USU) Physics Department has developed a curriculum centered around USU Physics Day at Lagoon.

With an upcoming change to Utah's core standards and a shift to more hands-on learning styles, the use of real-world learning offered by amusement park applications is analyzed in its ability to satisfy the Utah State Bureau of Education’s (USBE) SEEd standards. Amusement park learning allows educators a vehicle to capture students’ attention in the classroom by discussing science principles in a fun and exciting manner with a promise of …

Leveraging Commercial Nuclear Reactors To Power Space Exploration, Ben Johnson

Utah Space Grant Consortium

This study is aimed at exploring the adaptation of commercial nuclear reactors as an alternative to NASA’s current high-power fission reactor systems, particularly with respect to applications on the surface of Mars. The study concludes that while the Kilopower architecture is brilliantly poised to provide affordable, near-term power in the 1-10 kilowatts electric (kWe) range, the financial barrier to higher power scaling of such systems is significant. This financial barrier adds risk to the development of greater than 10kWe systems and is likely to result in the failure to successfully scale the technology to higher powers for space exploration applications. …

Internal Waves Generated From Asymmetric Topographies, Kyle Hakes

Utah Space Grant Consortium

Internal waves are a key part of the energy budget of the ocean and atmosphere. The generation of internal waves in the ocean from tides is dependent on the frequency of oscillation, the profile of the underwater mountain range, and the density of water in the surrounding ocean. A study of the effect of an asymmetric mountain range, with varying pro-files, on the generation of internal waves is presented. Results begin to indicate that the wave is mostly similar when generated on either side of the topography, but might extend to higher wavenumbers in Fourier space when generated on the …

Resistivity Of Nickel Silicide Thin Films, Rylan Woods

Utah Space Grant Consortium

The characterization of resistivity within thin films is paramount for proper integration into modern electronics wherein they show promise as contact materials due to their low contact resistance and high conductivity. Nickel silicide compounds often form in microelectronics at intersections between nickel and silicon, traditionally forming as a variety of intermetallic compounds including NiSi, Ni₂Si, Ni₃Si, Ni₃Si₂, and NiSi₂. Within this study, nickel silicide thin films ranging in thickness from 25nm to 110nm were synthesized on a silicon wafer substrate utilizing vapor deposition at a temperature of 900°C in low …

Implementing Theta-2-Theta Measurements To Measure Mirror Reflectance, Kylie Wolfe

Utah Space Grant Consortium

Our research group studies multilayer mirrors for use in space-based telescopes. The mirror property we are most interested in optimizing is reflectance. In the past, measuring the reflectance of our sample mirrors was difficult, as we either had to travel to the Advanced Light Source in Berkeley, California or we had to conduct and combine the data from many single-axis scans by hand. This made measuring reflectance tedious, error-prone, and time-consuming. By adding an automated theta-2-theta scan to our system, I removed these issues, allowing us to study our mirrors much more efficiently.

Mineralogy Of Great Salt Lake: An Analogue For Martian Evaporites, Calli B. Cahill, Adrik Z. Da Silva

Utah Space Grant Consortium

Gypsum (CaSO₄ · 2H₂O) and mirabilite (Na₂SO₄ · 10H₂O) are common precipitates at the Great Salt Lake (GSL). NASA’s Mars Exploration Rover, Opportunity, found veins of gypsum deposited by water in 2011 and gypsum has been detected on Mars as early as 2005 by the ESA’s Mars Express Orbiter. On Earth, gypsum is formed in hypersaline environments, in minerals left behind when water evaporates, trapping microorganisms in fluid inclusions. Likewise, GSL mirabilite develops when mineral-rich groundwater meets cold winter air to create crystalline structures. While there is no physical evidence of mirabilite …

The annual NASA Robotic Mining Challenge: Lunabotics tasks teams with building robots capable of traversing and mining simulated Lunar terrain. The competition goal is to utilize automation and sensing alongside mechanical systems to harvest icy regolith (gravel) from beneath the satellite’s surface.

This year, Utah Student Robotics sought to improve upon the design from last year. The 2019-2020 rover is based on proven NASA concepts, such as the RASSOR 2.0 digging drum, and the Rocker-Bogie mobility platform.
