Dynamics And Timescales Of Magmatic Processes At Cerro Uturuncu, Bolivia, Sarah Rasor
Dynamics And Timescales Of Magmatic Processes At Cerro Uturuncu, Bolivia, Sarah Rasor
NASA-Missouri Space Grant Consortium
Between 12-25°S latitude there is prolific volcanism fueled by the Altiplano-Puna Magmatic Body (APMB), a mid-crustal magma body above the 30° subduction of the Nazca plate and within 70-80 km thick South American crust. Cerro Uturuncu, the volcano directly above the APMB, demonstrates that the APMB experiences considerable mixing with the surrounding continental crust. Within the past 1 Ma, Uturuncu has experienced six distinct stages of andesitic to dacitic lava. With this research, we contribute greater understanding to the homogenization of and mixing within the APMB and comment on how this relates to magma residence times. The influx and recharge …

Analysis Of Laser Cut Living Hinge Pattern Design, Andrew Weber, Hussein Nassar
Analysis Of Laser Cut Living Hinge Pattern Design, Andrew Weber, Hussein Nassar
NASA-Missouri Space Grant Consortium
Living hinges are flexure bearings that consist of one material which makes up both the hinge and rigid end connections. They are typically made of plastics that can naturally bend without causing permanent strain. Plastic living hinges usually consist of a flat, thin strip of material connecting two ends, and have a wide range of commercial applications. The function of these living hinges can be replicated in plywood samples through subtractive manufacturing. Laser cut patterns produced in plywood samples reduce the flexural rigidity of the material and are popular amongst hobbyists.

High Pressure Injection Process For Ceramic Composites, Samuel Weiler
High Pressure Injection Process For Ceramic Composites, Samuel Weiler
NASA-Missouri Space Grant Consortium
Ceramic materials are valued for good heat resistance and corrosion resistance. Due to these benefits, they are widely used in the aviation, automotive, medical, construction, and other industries. Ceramic materials are also both hard and brittle, qualities that are not ideal in many applications. To reduce brittleness, and other undesirable characteristics of ceramics, engineers have turned to composites to increase the mechanical properties of these materials. By adding composite particles or fibers, these characteristics can be improved. Constructing ceramic composites is not without its challenges, however. Current processes are prone to high porosity, high shrinkage, and poor accuracy of parts. …
Performance Evaluation Of Additively Manufactured Carbon/Peek Composites, Matik S. Heskin
Performance Evaluation Of Additively Manufactured Carbon/Peek Composites, Matik S. Heskin
NASA-Missouri Space Grant Consortium
Carbon/PEEK composites have a broad range of applications due to their combinations of superior creep properties and excellent strength to weight ratios. Like all fiber-based composites they are limited geometrically by their required manufacturing processes. Additively manufactured (AM) materials overcome this issue and can be formed into incredibly complex shapes. By combining these two fields, a material limited in application by geometry can have its shortcomings supported with AM processes.
AM carbon/PEEK composites have already been created but this relatively new material still needs property characterization. Therefore, the objective of this work will be to evaluate the structural performance of …

Electricity On The Moon Through Reactors, Joseph Bui
NASA-Missouri Space Grant Consortium
There are many different ways to create electricity. One of the most common methods nowadays that people conclude to use is nuclear reactors. There are many different types of reactors but they all use similar methods to produce electricity. The most widely used method for reactors is fission, nuclear reactors. Reactors that use fission are common nowadays within the United States and across other countries, countries that are not able to afford nuclear reactors or have not moved to that method are in the works of doing so as it’s powerful, long lasting, reliable, and very low maintenance compared to …
Computations Of Flow Past A Three-Element 30p30n Airfoil Using Wray-Agarwal One Equation Turbulence Model, Karsten Hendrickson
Computations Of Flow Past A Three-Element 30p30n Airfoil Using Wray-Agarwal One Equation Turbulence Model, Karsten Hendrickson
NASA-Missouri Space Grant Consortium
The predictions of flow phenomenon that occur in high lift systems have proven to be challenging using the Reynolds-Averaged Navier-Stokes (RANS) equations with turbulence models. The complex interactions that occur among different elements of the wing can be difficult for turbulence models to accurately predict. Results from the recently developed Wray-Agarwal (WA) one-equation turbulence model, the frequently used Spalart-Allmaras (SA) and shear stress transport (SST) k-ω turbulence models are compared to experimental results to evaluate each model’s relative accuracy. The quadratic constitutive relation (QCR) is also used to produce results with the SA and WA models. It is shown that …

Isotopic Fractionation is a useful tool for investigating the formation of planetary bodies in the Solar System. Moderately volatile elements such as Potassium, Copper and Zinc can provide insight into the formative process and the origin of rocky planets. In this experiment Ortenberg basalt is heated to 1400° Celsius for different durations of time ranging from 1 minute at temperature to 7 hours at temperature under high vacuum conditions. The fractionation factor for K has been determined to be 0.9944 and the fractionation factor for Cu was found to be 0.9961. The fractionation factors of the Moon were found to …
Masses And Radii Of Subdwarf B Stars - Sed Fitting Method, Noah Singer
Masses And Radii Of Subdwarf B Stars - Sed Fitting Method, Noah Singer
NASA-Missouri Space Grant Consortium
The goal of this project is to determine masses and radii of hot subdwarf B stars in hopes of connecting these fundamental intrinsic properties to the evolutionary history of such stars. Subdwarf B stars burn helium in their core, serving as interesting physical laboratories, and the abundance of public data, including GAIA parallaxes and archival photometry, can be used to determine stellar characteristics. In this study, observed photometry is compared to synthetic photometry, calculated from a similar-stellaratmosphere model spectrum. This match determines the effective stellar temperature and radius. With an estimate of surface gravity, mass can be determined. Such determinations …
Distant Giant Planets And Their Influence On Inner Planet Formation, Caroline Witt
Distant Giant Planets And Their Influence On Inner Planet Formation, Caroline Witt
NASA-Missouri Space Grant Consortium
The most common planets within 1 AU of a star are a few Earth radii in size, dubbed 'super- Earths', and these planets exhibit a wide range of compositions and orbit properties. Yet our Solar system lacks a super-Earth. It is also known that it is possible for exoplanet systems to include a massive planet with an orbit distance of a few AU from the host star, similar to Jupiter in our solar system. It is natural to then question how the presence of such a massive, distant planet may affect the overall exoplanet system. This project investigated how the …

Investigating Outcomes Of Inner Planet Formation Influenced By A Jupiter-Like Perturber, Simarpreet Girn
NASA-Missouri Space Grant Consortium
The most common planets within 1 AU of a star are a few Earth radii in size, dubbed ‘super-Earths.’ Yet the Solar system lacks a super-Earth, and potentially the presence of Jupiter played a role. For this project, the outcomes of in situ inner planet formation under the influence of a massive outer planet were analyzed. Ninety-two N-body dynamical simulations were conducted of the in-situ formation process with a Jupiter-mass planet at a distance of five astronomical units from a host star. These simulations were then compared with the same inner planet conditions without a massive outer planet. The simulations …
