Enhanced 3d Image Reconstruction Using Scattered Light Tomography, Tyler O'Loughlin, Vern Hart

Utah Space Grant Consortium

Coherent diffraction imaging (CDI) is a powerful technique for reconstructing phase shifts occurring in biological samples by capturing the interference between scattered light. These diffraction patterns contain spectral information, where shorter wavelengths (higher spatial frequencies) yield images with enhanced spatial resolution, improving detail and accuracy. However, higher spatial frequencies are located further from the central axis, rendering them fainter and more challenging to measure. To address this, our group developed a gyroscopic CDI system featuring a rotating platform driven by a stepper motor. This platform positions the sample between a broadband light source and a beam profiler, which are mounted …

Genetic Analysis Of Great Salt Lake Microbialites, Alivia Preston, Bonnie Baxter

Utah Space Grant Consortium

Among the major contributors to the bottom of the food chain in Great Salt Lake (GSL), microbialites are mats of microorganisms supported by rock-like structures. The microbiome includes photosynthesizers such as cyanobacteria, but they also include more complex organisms such as algae. The microbialites are the foundation for the food chain in the lake, and without them, the food chain will likely face a collapse. As GSL is shrinking, more areas are exposed to drying out and high salt conditions. This project aims to analyze the genetic microbial community of the microbialites form 2016 and 2023 to see the effects …

Further Investigation Of Using Rr Lyrae Periods As A Tracer Of Multiple Populations In Globular Clusters, Brent Lane Racker Jr., Jonathan Barnes

Utah Space Grant Consortium

Recent work (Racker & Barnes 2024) using Gaia spacecraft data appeared to show a weak but noticeable correlation between the spread of periods for both the ab- and c-type RR Lyrae variable stars in certain Milky Way Globular Clusters (GCs) and the fraction of first-generation to the total number of stars as determined in (Milone et al. 2017). This research further suggests that the correlation is unaffected by angular distance from the GC center relieving the question of whether crowding or other effects impact the results. Then, looking outward, this correlation was used on just over one thousand RR Lyrae …

Cracking The Code For Pcb Cleanup: Pcr Optimization Meets Synthetic Biology, Leptzy Romero, Lane Law

Utah Space Grant Consortium

This study focuses on the construction of a plasmid harboring biphenyl (BPH) genes, with the aim of enabling potential degradation of polychlorinated biphenyls (PCBs). Optimization experiments were conducted to enhance PCR amplification and assembly efficiency. PCR conditions were refined using a primer concentration gradient and by varying magnesium chloride levels through adjustments in reaction buffer volume, resulting in improved specificity and yield. Six BPH gene fragments were successfully litigated into the pSHDY vector using Gibson Assembly, alongside a GA+ positive control. The resulting construct represents a foundational step toward engineering organisms capable of PCB biodegradation.

Optimizing Satellite Handoffs In Leo Constellations, A Predictive Model, Savanna Sanborn

Utah Space Grant Consortium

Low-Earth Orbit (LEO) satellites are huge players in the modern space infrastructure and are used for a variety of human needs, including public communication, weather imaging, and scientific research. Typically these satellites orbit at altitudes between 300km and 600km above the earth's surface, complete an entire orbit around the Earth in 90-100 minutes, and make several orbits around the earth in a given day.

Poly(2-Methyl 1-Pentene Sulfone) (Pmps) As A Potential Oxidation Retardant For Aluminum Mirrors For Space Telescopes, Kira Sand, Matthew Clarkson, Morgan Peterson, David Allred

Utah Space Grant Consortium

The reflectivity of aluminum mirrors, essential for capturing high-quality far-ultraviolet (FUV) images in space telescopes, is compromised by oxidation caused by exposure to Earth's atmosphere. Barrier coatings like magnesium fluoride can protect aluminum but still permit slow oxidation over time. To address this, we propose using photodegrading polymer films, which depolymerize under UV light in a vacuum, as a protective coating for aluminum mirrors until they exit Earth's atmosphere. Our research focuses on Poly(2-methyl 1-pentene sulfone) (PMPS), which depolymerize when exposed to ultraviolet light in vacuum, ensuring stability until reaching space.

Mapping Accretion Around The Black Hole X-Ray Binary Maxi J1803-298 With Reflection, Brianna Searle, Benjamin Coughenour

Utah Space Grant Consortium

MAXI J1803-298 is a recently discovered transient black hole (BH) X-ray binary that went into outburst on May 1st, 2021, and was detected with MAXI/GSC¹ onboard the ISS. NuSTAR observed MAXI J1803-298 four times during its outburst (see Table 1, Figure 1)^2,3. I modeled the spectrum to see reflection features and learn about the inner accretion disk and the environment around the BH. Figure 1 and Table 1 show that the outburst started roughly on May 1st, the peak was on May 14th, and the last observation was on June 17th.

Increasing Rocket Reusability Via Guided Recovery Systems, Chandler Taylor

Utah Space Grant Consortium

As rocketry continues to emphasize reusability and cost-effectiveness, the question arises: how can these goals be achieved in the context of sounding rockets? One promising method is the use of air brakes. These systems can serve multiple purposes, such as assisting in stage separation or guiding a rocket safely back to the ground. Much of the recent air brake testing has taken place at events like the Intercollegiate Rocket Engineering Competition (IREC), often to meet specific altitude targets. But this paper aims to use air brakes to increase the rockets recoverability and reusability by employing air brake gird fins to …

High-Velocity Pulsar Kicks Via Anisotropic Neutrino Emission, Tate R. Thomas, Alexander M. Panin

Utah Space Grant Consortium

Observations reveal that some neutron stars (NS) exhibit high velocities, reaching over 1000 km/s in some instances. This cannot be attributed to the orbital velocity of the NS around our Milky Way galaxy, as it is around 250 km/s on average. The origin of this phenomenon, known as a pulsar kick, is not fully understood and remains a subject of debate among astrophysicists.

During NS formation, the rotation and strong (potentially asymmetric) magnetic field of its progenitor star may result in an asymmetric collapse of the star's core plasma. If this is the case, we might anticipate the formation of …

Increased Angle Space For A Fourier Scatter Microscope Via Simultaneous Axial And Off-Axis Imaging, Haley Blackburn, Marren Williams, Vincent M. Rossi

Utah Space Grant Consortium

Fourier Scatter Imaging (FSI) has proven to be an innovative tool for measuring particle size. This research incorporates Fourier optics into a scatter imaging system with the addition of an off-axis pathway in a Fourier Scatter Microscope. The system uses 0.28 numerical aperture (NA) long working distance objectives that provide angular resolution over +/- 16.3° in the forward direction and 90° +/- 16.3° in the off-axis direction. This setup enables simultaneous capture of axial and off-axis scatter signals using a shared camera, significantly enhancing the angular scattering measurement capabilities. This proof-of-principle system demonstrates the potential for improvements in scattering image …
